[**ACL (Access Control List)**](https://en.wikipedia.org/wiki/Access_control_list) -2. **ACL with [superuser](https://en.wikipedia.org/wiki/Superuser)** -3. **ACL without users**: especially useful for systems that don't have authentication or user log-ins. -3. **ACL without resources**: some scenarios may target for a type of resources instead of an individual resource by using permissions like ``write-article``, ``read-log``. It doesn't control the access to a specific article or log. -4. **[RBAC (Role-Based Access Control)](https://en.wikipedia.org/wiki/Role-based_access_control)** -5. **RBAC with resource roles**: both users and resources can have roles (or groups) at the same time. -6. **RBAC with domains/tenants**: users can have different role sets for different domains/tenants. -7. **[ABAC (Attribute-Based Access Control)](https://en.wikipedia.org/wiki/Attribute-Based_Access_Control)**: syntax sugar like ``resource.Owner`` can be used to get the attribute for a resource. -8. **[RESTful](https://en.wikipedia.org/wiki/Representational_state_transfer)**: supports paths like ``/res/*``, ``/res/:id`` and HTTP methods like ``GET``, ``POST``, ``PUT``, ``DELETE``. -9. **Deny-override**: both allow and deny authorizations are supported, deny overrides the allow. -10. **Priority**: the policy rules can be prioritized like firewall rules. - -## How it works? - -In Casbin, an access control model is abstracted into a CONF file based on the **PERM metamodel (Policy, Effect, Request, Matchers)**. So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. You can customize your own access control model by combining the available models. For example, you can get RBAC roles and ABAC attributes together inside one model and share one set of policy rules. - -The most basic and simplest model in Casbin is ACL. ACL's model CONF is: - -```ini -# Request definition -[request_definition] -r = sub, obj, act - -# Policy definition -[policy_definition] -p = sub, obj, act - -# Policy effect -[policy_effect] -e = some(where (p.eft == allow)) - -# Matchers -[matchers] -m = r.sub == p.sub && r.obj == p.obj && r.act == p.act - -``` - -An example policy for ACL model is like: - -``` -p, alice, data1, read -p, bob, data2, write -``` - -It means: - -- alice can read data1 -- bob can write data2 - -We also support multi-line mode by appending '\\' in the end: - -```ini -# Matchers -[matchers] -m = r.sub == p.sub && r.obj == p.obj \ - && r.act == p.act -``` - -Further more, if you are using ABAC, you can try operator `in` like following in Casbin **golang** edition (jCasbin and Node-Casbin are not supported yet): - -```ini -# Matchers -[matchers] -m = r.obj == p.obj && r.act == p.act || r.obj in ('data2', 'data3') -``` - -But you **SHOULD** make sure that the length of the array is **MORE** than **1**, otherwise there will cause it to panic. - -For more operators, you may take a look at [govaluate](https://github.com/casbin/govaluate) - -## Features - -What Casbin does: - -1. enforce the policy in the classic ``{subject, object, action}`` form or a customized form as you defined, both allow and deny authorizations are supported. -2. handle the storage of the access control model and its policy. -3. manage the role-user mappings and role-role mappings (aka role hierarchy in RBAC). -4. support built-in superuser like ``root`` or ``administrator``. A superuser can do anything without explicit permissions. -5. multiple built-in operators to support the rule matching. For example, ``keyMatch`` can map a resource key ``/foo/bar`` to the pattern ``/foo*``. - -What Casbin does NOT do: - -1. authentication (aka verify ``username`` and ``password`` when a user logs in) -2. manage the list of users or roles. I believe it's more convenient for the project itself to manage these entities. Users usually have their passwords, and Casbin is not designed as a password container. However, Casbin stores the user-role mapping for the RBAC scenario. - -## Installation - -``` -go get github.com/casbin/casbin/v2 -``` - -## Documentation - -https://casbin.org/docs/overview - -## Online editor - -You can also use the online editor (https://casbin.org/editor/) to write your Casbin model and policy in your web browser. It provides functionality such as ``syntax highlighting`` and ``code completion``, just like an IDE for a programming language. - -## Tutorials - -https://casbin.org/docs/tutorials - -## Get started - -1. New a Casbin enforcer with a model file and a policy file: - - ```go - e, _ := casbin.NewEnforcer("path/to/model.conf", "path/to/policy.csv") - ``` - -Note: you can also initialize an enforcer with policy in DB instead of file, see [Policy-persistence](#policy-persistence) section for details. - -2. Add an enforcement hook into your code right before the access happens: - - ```go - sub := "alice" // the user that wants to access a resource. - obj := "data1" // the resource that is going to be accessed. - act := "read" // the operation that the user performs on the resource. - - if res, _ := e.Enforce(sub, obj, act); res { - // permit alice to read data1 - } else { - // deny the request, show an error - } - ``` - -3. Besides the static policy file, Casbin also provides API for permission management at run-time. For example, You can get all the roles assigned to a user as below: - - ```go - roles, _ := e.GetImplicitRolesForUser(sub) - ``` - -See [Policy management APIs](#policy-management) for more usage. - -## Policy management - -Casbin provides two sets of APIs to manage permissions: - -- [Management API](https://casbin.org/docs/management-api): the primitive API that provides full support for Casbin policy management. -- [RBAC API](https://casbin.org/docs/rbac-api): a more friendly API for RBAC. This API is a subset of Management API. The RBAC users could use this API to simplify the code. - -We also provide a [web-based UI](https://casbin.org/docs/admin-portal) for model management and policy management: - -![model editor](https://hsluoyz.github.io/casbin/ui_model_editor.png) - -![policy editor](https://hsluoyz.github.io/casbin/ui_policy_editor.png) - -## Policy persistence - -https://casbin.org/docs/adapters - -## Policy consistence between multiple nodes - -https://casbin.org/docs/watchers - -## Role manager - -https://casbin.org/docs/role-managers - -## Benchmarks - -https://casbin.org/docs/benchmark - -## Examples - -| Model | Model file | Policy file | -|---------------------------|----------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------| -| ACL | [basic_model.conf](https://github.com/casbin/casbin/blob/master/examples/basic_model.conf) | [basic_policy.csv](https://github.com/casbin/casbin/blob/master/examples/basic_policy.csv) | -| ACL with superuser | [basic_model_with_root.conf](https://github.com/casbin/casbin/blob/master/examples/basic_with_root_model.conf) | [basic_policy.csv](https://github.com/casbin/casbin/blob/master/examples/basic_policy.csv) | -| ACL without users | [basic_model_without_users.conf](https://github.com/casbin/casbin/blob/master/examples/basic_without_users_model.conf) | [basic_policy_without_users.csv](https://github.com/casbin/casbin/blob/master/examples/basic_without_users_policy.csv) | -| ACL without resources | [basic_model_without_resources.conf](https://github.com/casbin/casbin/blob/master/examples/basic_without_resources_model.conf) | [basic_policy_without_resources.csv](https://github.com/casbin/casbin/blob/master/examples/basic_without_resources_policy.csv) | -| RBAC | [rbac_model.conf](https://github.com/casbin/casbin/blob/master/examples/rbac_model.conf) | [rbac_policy.csv](https://github.com/casbin/casbin/blob/master/examples/rbac_policy.csv) | -| RBAC with resource roles | [rbac_model_with_resource_roles.conf](https://github.com/casbin/casbin/blob/master/examples/rbac_with_resource_roles_model.conf) | [rbac_policy_with_resource_roles.csv](https://github.com/casbin/casbin/blob/master/examples/rbac_with_resource_roles_policy.csv) | -| RBAC with domains/tenants | [rbac_model_with_domains.conf](https://github.com/casbin/casbin/blob/master/examples/rbac_with_domains_model.conf) | [rbac_policy_with_domains.csv](https://github.com/casbin/casbin/blob/master/examples/rbac_with_domains_policy.csv) | -| ABAC | [abac_model.conf](https://github.com/casbin/casbin/blob/master/examples/abac_model.conf) | N/A | -| RESTful | [keymatch_model.conf](https://github.com/casbin/casbin/blob/master/examples/keymatch_model.conf) | [keymatch_policy.csv](https://github.com/casbin/casbin/blob/master/examples/keymatch_policy.csv) | -| Deny-override | [rbac_model_with_deny.conf](https://github.com/casbin/casbin/blob/master/examples/rbac_with_deny_model.conf) | [rbac_policy_with_deny.csv](https://github.com/casbin/casbin/blob/master/examples/rbac_with_deny_policy.csv) | -| Priority | [priority_model.conf](https://github.com/casbin/casbin/blob/master/examples/priority_model.conf) | [priority_policy.csv](https://github.com/casbin/casbin/blob/master/examples/priority_policy.csv) | - -## Middlewares - -Authz middlewares for web frameworks: https://casbin.org/docs/middlewares - -## Our adopters - -https://casbin.org/docs/adopters - -## How to Contribute - -Please read the [contributing guide](CONTRIBUTING.md). - -## Contributors - -This project exists thanks to all the people who contribute. - - -## Backers - -Thank you to all our backers! 🙏 [[Become a backer](https://opencollective.com/casbin#backer)] - - - -## Sponsors - -Support this project by becoming a sponsor.

The resultant expression will be able to invoke those functions during evaluation. Once parsed, an expression cannot have functions added or removed - a new expression will need to be created if you want to change the functions, or behavior of said functions. - -Functions always take the form `()`, including parens. Functions can have an empty list of parameters, like `()`, but still must have parens. - -If the expression contains something that looks like it ought to be a function (such as `foo()`), but no such function was given to it, it will error on parsing. - -Functions must be of type `map[string]govaluate.ExpressionFunction`. `ExpressionFunction`, for brevity, has the following signature: - -`func(args ...interface{}) (interface{}, error)` - -Where `args` is whatever is passed to the function when called. If a non-nil error is returned from a function during evaluation, the evaluation stops and ultimately returns that error to the caller of `Evaluate()` or `Eval()`. - -## Built-in functions - -There aren't any builtin functions. The author is opposed to maintaining a standard library of functions to be used. - -Every use case of this library is different, and even in simple use cases (such as parameters, see above) different users need different behavior, naming, or even functionality. The author prefers that users make their own decisions about what functions they need, and how they operate. - -# Equality - -The `==` and `!=` operators involve a moderately complex workflow. They use [`reflect.DeepEqual`](https://golang.org/pkg/reflect/#DeepEqual). This is for complicated reasons, but there are some types in Go that cannot be compared with the native `==` operator. Arrays, in particular, cannot be compared - Go will panic if you try. One might assume this could be handled with the type checking system in `govaluate`, but unfortunately without reflection there is no way to know if a variable is a slice/array. Worse, structs can be incomparable if they _contain incomparable types_. - -It's all very complicated. Fortunately, Go includes the `reflect.DeepEqual` function to handle all the edge cases. Currently, `govaluate` uses that for all equality/inequality. diff --git a/vendor/github.com/casbin/govaluate/OperatorSymbol.go b/vendor/github.com/casbin/govaluate/OperatorSymbol.go deleted file mode 100644 index 4b810658..00000000 --- a/vendor/github.com/casbin/govaluate/OperatorSymbol.go +++ /dev/null @@ -1,309 +0,0 @@ -package govaluate -

-Provides support for evaluating arbitrary C-like artithmetic/string expressions. - -Why can't you just write these expressions in code? --- - -Sometimes, you can't know ahead-of-time what an expression will look like, or you want those expressions to be configurable. -Perhaps you've got a set of data running through your application, and you want to allow your users to specify some validations to run on it before committing it to a database. Or maybe you've written a monitoring framework which is capable of gathering a bunch of metrics, then evaluating a few expressions to see if any metrics should be alerted upon, but the conditions for alerting are different for each monitor. - -A lot of people wind up writing their own half-baked style of evaluation language that fits their needs, but isn't complete. Or they wind up baking the expression into the actual executable, even if they know it's subject to change. These strategies may work, but they take time to implement, time for users to learn, and induce technical debt as requirements change. This library is meant to cover all the normal C-like expressions, so that you don't have to reinvent one of the oldest wheels on a computer. - -How do I use it? --- - -You create a new EvaluableExpression, then call "Evaluate" on it. - -```go - expression, err := govaluate.NewEvaluableExpression("10 > 0"); - result, err := expression.Evaluate(nil); - // result is now set to "true", the bool value. -``` - -Cool, but how about with parameters? - -```go - expression, err := govaluate.NewEvaluableExpression("foo > 0"); - - parameters := make(map[string]interface{}, 8) - parameters["foo"] = -1; - - result, err := expression.Evaluate(parameters); - // result is now set to "false", the bool value. -``` - -That's cool, but we can almost certainly have done all that in code. What about a complex use case that involves some math? - -```go - expression, err := govaluate.NewEvaluableExpression("(requests_made * requests_succeeded / 100) >= 90"); - - parameters := make(map[string]interface{}, 8) - parameters["requests_made"] = 100; - parameters["requests_succeeded"] = 80; - - result, err := expression.Evaluate(parameters); - // result is now set to "false", the bool value. -``` - -Or maybe you want to check the status of an alive check ("smoketest") page, which will be a string? - -```go - expression, err := govaluate.NewEvaluableExpression("http_response_body == 'service is ok'"); - - parameters := make(map[string]interface{}, 8) - parameters["http_response_body"] = "service is ok"; - - result, err := expression.Evaluate(parameters); - // result is now set to "true", the bool value. -``` - -These examples have all returned boolean values, but it's equally possible to return numeric ones. - -```go - expression, err := govaluate.NewEvaluableExpression("(mem_used / total_mem) * 100"); - - parameters := make(map[string]interface{}, 8) - parameters["total_mem"] = 1024; - parameters["mem_used"] = 512; - - result, err := expression.Evaluate(parameters); - // result is now set to "50.0", the float64 value. -``` - -You can also do date parsing, though the formats are somewhat limited. Stick to RF3339, ISO8061, unix date, or ruby date formats. If you're having trouble getting a date string to parse, check the list of formats actually used: [parsing.go:248](https://github.com/casbin/govaluate/blob/0580e9b47a69125afa0e4ebd1cf93c49eb5a43ec/parsing.go#L258). - -```go - expression, err := govaluate.NewEvaluableExpression("'2014-01-02' > '2014-01-01 23:59:59'"); - result, err := expression.Evaluate(nil); - - // result is now set to true -``` - -Expressions are parsed once, and can be re-used multiple times. Parsing is the compute-intensive phase of the process, so if you intend to use the same expression with different parameters, just parse it once. Like so; - -```go - expression, err := govaluate.NewEvaluableExpression("response_time <= 100"); - parameters := make(map[string]interface{}, 8) - - for { - parameters["response_time"] = pingSomething(); - result, err := expression.Evaluate(parameters) - } -``` - -The normal C-standard order of operators is respected. When writing an expression, be sure that you either order the operators correctly, or use parenthesis to clarify which portions of an expression should be run first. - -Escaping characters --- - -Sometimes you'll have parameters that have spaces, slashes, pluses, ampersands or some other character -that this library interprets as something special. For example, the following expression will not -act as one might expect: - - "response-time < 100" - -As written, the library will parse it as "[response] minus [time] is less than 100". In reality, -"response-time" is meant to be one variable that just happens to have a dash in it. - -There are two ways to work around this. First, you can escape the entire parameter name: - - "[response-time] < 100" - -Or you can use backslashes to escape only the minus sign. - - "response\\-time < 100" - -Backslashes can be used anywhere in an expression to escape the very next character. Square bracketed parameter names can be used instead of plain parameter names at any time. - -Functions --- - -You may have cases where you want to call a function on a parameter during execution of the expression. Perhaps you want to aggregate some set of data, but don't know the exact aggregation you want to use until you're writing the expression itself. Or maybe you have a mathematical operation you want to perform, for which there is no operator; like `log` or `tan` or `sqrt`. For cases like this, you can provide a map of functions to `NewEvaluableExpressionWithFunctions`, which will then be able to use them during execution. For instance; - -```go - functions := map[string]govaluate.ExpressionFunction { - "strlen": func(args ...interface{}) (interface{}, error) { - length := len(args[0].(string)) - return (float64)(length), nil - }, - } - - expString := "strlen('someReallyLongInputString') <= 16" - expression, _ := govaluate.NewEvaluableExpressionWithFunctions(expString, functions) - - result, _ := expression.Evaluate(nil) - // result is now "false", the boolean value -``` - -Functions can accept any number of arguments, correctly handles nested functions, and arguments can be of any type (even if none of this library's operators support evaluation of that type). For instance, each of these usages of functions in an expression are valid (assuming that the appropriate functions and parameters are given): - -```go -"sqrt(x1 ** y1, x2 ** y2)" -"max(someValue, abs(anotherValue), 10 * lastValue)" -``` - -Functions cannot be passed as parameters, they must be known at the time when the expression is parsed, and are unchangeable after parsing. - -Accessors --- - -If you have structs in your parameters, you can access their fields and methods in the usual way. For instance, given a struct that has a method "Echo", present in the parameters as `foo`, the following is valid: - - "foo.Echo('hello world')" - -Fields are accessed in a similar way. Assuming `foo` has a field called "Length": - - "foo.Length > 9000" - -The values of a `map` are accessed in the same way. Assuming the parameter `foo` is `map[string]int{ "bar": 1 }` - - "foo.bar == 1" - -Accessors can be nested to any depth, like the following - - "foo.Bar.Baz.SomeFunction()" - -This may be convenient, but note that using accessors involves a _lot_ of reflection. This makes the expression about four times slower than just using a parameter (consult the benchmarks for more precise measurements on your system). -If at all reasonable, the author recommends extracting the values you care about into a parameter map beforehand, or defining a struct that implements the `Parameters` interface, and which grabs fields as required. If there are functions you want to use, it's better to pass them as expression functions (see the above section). These approaches use no reflection, and are designed to be fast and clean. - -What operators and types does this support? --- - -* Modifiers: `+` `-` `/` `*` `&` `|` `^` `**` `%` `>>` `<<` -* Comparators: `>` `>=` `<` `<=` `==` `!=` `=~` `!~` -* Logical ops: `||` `&&` -* Numeric constants, as 64-bit floating point (`12345.678`) -* String constants (single quotes: `'foobar'`) -* Date constants (single quotes, using any permutation of RFC3339, ISO8601, ruby date, or unix date; date parsing is automatically tried with any string constant) -* Boolean constants: `true` `false` -* Parenthesis to control order of evaluation `(` `)` -* Arrays (anything separated by `,` within parenthesis: `(1, 2, 'foo')`) -* Prefixes: `!` `-` `~` -* Ternary conditional: `?` `:` -* Null coalescence: `??` - -See [MANUAL.md](https://github.com/casbin/govaluate/blob/master/MANUAL.md) for exacting details on what types each operator supports. - -Types --- - -Some operators don't make sense when used with some types. For instance, what does it mean to get the modulo of a string? What happens if you check to see if two numbers are logically AND'ed together? - -Everyone has a different intuition about the answers to these questions. To prevent confusion, this library will _refuse to operate_ upon types for which there is not an unambiguous meaning for the operation. See [MANUAL.md](https://github.com/casbin/govaluate/blob/master/MANUAL.md) for details about what operators are valid for which types. - -Benchmarks --- - -If you're concerned about the overhead of this library, a good range of benchmarks are built into this repo. You can run them with `go test -bench=.`. The library is built with an eye towards being quick, but has not been aggressively profiled and optimized. For most applications, though, it is completely fine. - -For a very rough idea of performance, here are the results output from a benchmark run on a 3rd-gen Macbook Pro (Linux Mint 17.1). - -``` -BenchmarkSingleParse-12 1000000 1382 ns/op -BenchmarkSimpleParse-12 200000 10771 ns/op -BenchmarkFullParse-12 30000 49383 ns/op -BenchmarkEvaluationSingle-12 50000000 30.1 ns/op -BenchmarkEvaluationNumericLiteral-12 10000000 119 ns/op -BenchmarkEvaluationLiteralModifiers-12 10000000 236 ns/op -BenchmarkEvaluationParameters-12 5000000 260 ns/op -BenchmarkEvaluationParametersModifiers-12 3000000 547 ns/op -BenchmarkComplexExpression-12 2000000 963 ns/op -BenchmarkRegexExpression-12 100000 20357 ns/op -BenchmarkConstantRegexExpression-12 1000000 1392 ns/op -ok -``` - -API Breaks --- - -While this library has very few cases which will ever result in an API break, it can happen. If you are using this in production, vendor the commit you've tested against, or use gopkg.in to redirect your import (e.g., `import "gopkg.in/casbin/govaluate.v1"`). Master branch (while infrequent) _may_ at some point contain API breaking changes, and the author will have no way to communicate these to downstreams, other than creating a new major release. - -Releases will explicitly state when an API break happens, and if they do not specify an API break it should be safe to upgrade. - -License --- - -This project is licensed under the MIT general use license. You're free to integrate, fork, and play with this code as you feel fit without consulting the author, as long as you provide proper credit to the author in your works. diff --git a/vendor/github.com/casbin/govaluate/TokenKind.go b/vendor/github.com/casbin/govaluate/TokenKind.go deleted file mode 100644 index 7c9516d2..00000000 --- a/vendor/github.com/casbin/govaluate/TokenKind.go +++ /dev/null @@ -1,75 +0,0 @@ -package govaluate - -/* - Represents all valid types of tokens that a token can be. -*/ -type TokenKind int - -const ( - UNKNOWN TokenKind = iota - - PREFIX - NUMERIC - BOOLEAN - STRING - PATTERN - TIME - VARIABLE - FUNCTION - SEPARATOR - ACCESSOR - - COMPARATOR - LOGICALOP - MODIFIER - - CLAUSE - CLAUSE_CLOSE - - TERNARY -) - -/* - GetTokenKindString returns a string that describes the given TokenKind. - e.g., when passed the NUMERIC TokenKind, this returns the string "NUMERIC". -*/ -func (kind TokenKind) String() string { - - switch kind { - - case PREFIX: - return "PREFIX" - case NUMERIC: - return "NUMERIC" - case BOOLEAN: - return "BOOLEAN" - case STRING: - return "STRING" - case PATTERN: - return "PATTERN" - case TIME: - return "TIME" - case VARIABLE: - return "VARIABLE" - case FUNCTION: - return "FUNCTION" - case SEPARATOR: - return "SEPARATOR" - case COMPARATOR: - return "COMPARATOR" - case LOGICALOP: - return "LOGICALOP" - case MODIFIER: - return "MODIFIER" - case CLAUSE: - return "CLAUSE" - case CLAUSE_CLOSE: - return "CLAUSE_CLOSE" - case TERNARY: - return "TERNARY" - case ACCESSOR: - return "ACCESSOR" - } - - return "UNKNOWN" -} diff --git a/vendor/github.com/casbin/govaluate/evaluationStage.go b/vendor/github.com/casbin/govaluate/evaluationStage.go deleted file mode 100644 index 965040a7..00000000 --- a/vendor/github.com/casbin/govaluate/evaluationStage.go +++ /dev/null @@ -1,542 +0,0 @@ -package govaluate - -import ( - "errors" - "fmt" - "math" - "reflect" - "regexp" - "strings" - "unicode" -) - -const ( - logicalErrorFormat string = "Value '%v' cannot be used with the logical operator '%v', it is not a bool" - modifierErrorFormat string = "Value '%v' cannot be used with the modifier '%v', it is not a number" - comparatorErrorFormat string = "Value '%v' cannot be used with the comparator '%v', it is not a number" - ternaryErrorFormat string = "Value '%v' cannot be used with the ternary operator '%v', it is not a bool" - prefixErrorFormat string = "Value '%v' cannot be used with the prefix '%v'" -) - -type evaluationOperator func(left interface{}, right interface{}, parameters Parameters) (interface{}, error) -type stageTypeCheck func(value interface{}) bool -type stageCombinedTypeCheck func(left interface{}, right interface{}) bool - -type evaluationStage struct { - symbol OperatorSymbol - - leftStage, rightStage *evaluationStage - - // the operation that will be used to evaluate this stage (such as adding [left] to [right] and return the result) - operator evaluationOperator - - // ensures that both left and right values are appropriate for this stage.
