準備VSCode

在官網下載最新版的VSCode:git

安裝Golang插件

打開擴展面板github

VSCode->查看->擴展golang
找到Go插件在搜索框裏輸入Go, 找到第二行寫有 Rich Go language support for Visual Studio Code的插件, 點擊安裝json

注意不是排名最高的編輯器
重啓編輯器spa

配置啓動項

打開調試面板插件

VSCode->查看->調試命令行
添加調試目標debug

在"沒有調試"的下拉框中點擊"添加配置.."調試

添加目標調試配置

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插件自動生成的

"env"爲設置環境變量, 設置爲你的工程目錄就能夠(包含bin, src的文件夾)

準備調試插件

此時找到main.go按F5, 會報錯提示:

Failded to continue:"Cannot find Delve debugger. Install from https://github.com/derekparker/delve & ensure it is in your "GOPATH/bin" or "PATH"

咱們使用go命令行編譯調試器

go get github.com/derekparker/delve/cmd/dlv

將dlv調試器放在GOPATH(工程目錄)的bin目錄下

開始調試

選中要調試的main.go, 點擊F5, 既能夠開始調試

調試快捷鍵和Visual Studio系一致

F9 切換斷點
F10 Step over
F11 Step in
Shift+F11 Step out

注意點

某些結構體成員沒法直接顯示時, 能夠直接選中變量名, 添加到監視, 或者右鍵點擊: "調試:求值"

多項目調試

在launch.json中能夠添加多組調試入口, 經過調試面板中選中對應的配置開啓不一樣目標的調試

{
    "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}"是以當前選中文件做爲啓動點

更建議使用"program"的"${workspaceRoot}", 以包名做爲啓動點的方式進行配置
