# 1. 环境
|
||
golang1.18.1
|
||
调试端: win10+vscode
|
||
被调试端: ubuntu20.04LTS+dlv
|
||
## dlv安装
|
||
参考官方文档https://github.com/go-delve/delve/tree/master/Documentation/installation
|
||
```
|
||
go install github.com/go-delve/delve/cmd/dlv@latest
|
||
```
|
||
|
||
## 被调试端
|
||
```
|
||
cd /your-src-path #要确保两端源码一致
|
||
dlv debug --headless --listen=:2345 --api-version=2
|
||
# 如果失败可查看更多日志
|
||
# dlv debug --headless --listen=:2345 --api-version=2 --log --log-output=rpc,dap,debugger
|
||
```
|
||
|
||
## 调试端（vscode）
|
||
```
|
||
打开vscode，修改launch.json，增加下面远程调试配置
|
||
{
|
||
"version": "0.2.0",
|
||
"configurations": [
|
||
{
|
||
"name": "RemoteDebug",
|
||
"type": "go",
|
||
"request": "attach",
|
||
"mode": "remote",
|
||
"port": 2345,
|
||
"host": "192.168.3.29",
|
||
}
|
||
]
|
||
}
|
||
按F5启动调试
|
||
```
|
||
|
||
## 没有公网IP或不在同一个局域网，无法直连如何调试
|
||
到https://openp2p.cn/注册一个用户获得token，两端安装一个客户端程序，可将被调试端的2345端口，通过p2p连接映射到调试端本地。
|
||
p2p连接可通过web配置 https://github.com/openp2p-cn/openp2p/blob/master/README-ZH.md#%E5%BF%AB%E9%80%9F%E5%85%A5%E9%97%A8
|
||
|
||
也可以手动下载https://github.com/openp2p-cn/openp2p/releases 通过命令行手动配置
|
||
|
||
```
|
||
# 注意替换下面YOUR-开头的参数改成自己的
|
||
./openp2p -node YOUR-DEBUG-SERVER -token YOUR-TOKEN
|
||
|
||
openp2p.exe -node YOUR-DEBUG-CLIENT -token YOUR-TOKEN -peernode YOUR-DEBUG-SERVER -dstport 2345 -srcport 2345
|
||
|
||
2022/04/22 11:07:26 25680 INFO LISTEN ON PORT tcp:2345 START
|
||
#显示这条日志说明成功了
|
||
```
|
||
|
||
p2p端口映射完成后，把vscode的配置改成本地127.0.0.1，一样可以顺利调试。
|
||
```
|
||
{
|
||
"version": "0.2.0",
|
||
"configurations": [
|
||
{
|
||
"name": "RemoteDebug",
|
||
"type": "go",
|
||
"request": "attach",
|
||
"mode": "remote",
|
||
"port": 2345,
|
||
"host": "127.0.0.1",
|
||
}
|
||
]
|
||
}
|
||
```
