准备VSCode
在官网下载最新版的VSCode:
Visual Studio Code - Code Editing. Redefined
安装Golang插件
- 打开扩展面板
VSCode->查看->扩展 - 找到Go插件 在搜索框里输入Go, 找到第二行写有 Rich Go language support for Visual Studio Code的插件, 点击安装
- 重启编辑器
配置启动项
- 打开调试面板
VSCode->查看->调试 - 添加调试目标
在”没有调试”的下拉框中点击”添加配置..” - 添加目标调试配置
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch",
"type": "go",
"request": "launch",
"mode": "debug",
"remotePath": "",
"port": 2345,
"host": "127.0.0.1",
"program": "${fileDirname}",
"env": {
"GOPATH":"D:/Develop/vscodegolang"
},
"args": [],
"showLog": true
}
]
}其中: “port”, “host”都是go插件自动生成的
“env”为设置环境变量, 设置为你的工程目录就可以(包含bin, src的文件夹)
准备调试插件
我们使用go命令行编译调试器
go get github.com/derekparker/delve/cmd/dlv开始调试
选中要调试的main.go, 点击F5, 既可以开始调试
调试快捷键和Visual Studio系一致
- F9 切换断点
- F10 Step over
- F11 Step in
- Shift+F11 Step out
多项目调试
在launch.json中可以添加多组调试入口, 通过调试面板中选中对应的配置开启不同目标的调试
{
"version": "0.2.0",
"configurations": [
{
"name": "client",
"type": "go",
"request": "launch",
"mode": "debug",
"remotePath": "",
"port": 2345,
"host": "127.0.0.1",
"program": "${fileDirname}",
"env": {
"GOPATH":"D:/Develop/vscodegolang"
},
"args": [],
"showLog": true
},
{
"name": "server",
"type": "go",
"request": "launch",
"mode": "debug",
"remotePath": "",
"port": 2345,
"host": "127.0.0.1",
"program": "${workspaceRoot}/src/server",
"env": {
"GOPATH":"D:/Develop/vscodegolang"
},
"args": [],
"showLog": true
}
]
}“program”中的”${fileDirname}”是以当前选中文件作为启动点
更建议使用”program”的”${workspaceRoot}”, 以包名作为启动点的方式进行配置
