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。
