准备VSCode
在官网下载最新版的VSCode:
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
注意不是排名最高的
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
例子:
{ "version": "0.2.0", "configurations": [ { "name": "Launch", "type": "go", "request": "launch", "mode": "debug", "remotePath": "", "port": 2345, "host": "127.0.0.1", "program": "${fileDirname}", "env": { "GOPATH":"D:/Develop/vscodegolang" }, "args": [], "showLog": true } ] }
其中: "port", "host"都是go插件自动生成的
"env"为设置环境变量, 设置为你的工程目录就可以(包含bin, src的文件夹)
准备调试插件
此时找到main.go按F5, 会报错提示:
Failded to continue:"Cannot find Delve debugger. Install from https://github.com/derekparker/delve & ensure it is in your "GOPATH/bin" or "PATH"
我们使用go命令行编译调试器
go get github.com/derekparker/delve/cmd/dlv
将dlv调试器放在GOPATH(工程目录)的bin目录下
开始调试
选中要调试的main.go, 点击F5, 既可以开始调试
调试快捷键和Visual Studio系一致
F9 切换断点
F10 Step over
F11 Step in
Shift+F11 Step out
注意点
某些结构体成员无法直接显示时, 可以直接选中变量名, 添加到监视, 或者右键点击: "调试:求值"
多项目调试
在launch.json中可以添加多组调试入口, 通过调试面板中选中对应的配置开启不同目标的调试
{ "version": "0.2.0", "configurations": [ { "name": "client", "type": "go", "request": "launch", "mode": "debug", "remotePath": "", "port": 2345, "host": "127.0.0.1", "program": "${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
