准备VSCode

在官网下载最新版的VSCode:

Visual Studio Code - Code Editing. Redefined**

安装Golang插件

配置启动项

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

注意点

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
