Vscode调试golang的debug

配置启动项

　　打开调试面板：VSCode->查看->调试

　　添加调试目标：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"post","host"都是go插件自动生成的，“env”为设置环境变量，设置为工程目录包含bin、src的文件夹

准备调试插件

　　选中要调试的main.go，点击F5会报错误提示：Failded to continue:"Cannot find Delve debugger. Install from https://github.com/derekparker/delve & ensure it is in your "GOPATH/bin" or "PATH"

　　使用命令编译调试器：go get github.com/derekparker/delve/cmd/dlv　　将dlv调试器放在GOPATH的bin目录下

开始调试

　　选中要调试的main.go，点击F5可以开始调试

　　调试快捷键：

　　　　　　F9 切换断点

　　　　　　F10 Step over

　　　　　　F11 Step in

　　　　　　Shift+F11 Step out

　　注意：有些结构体成员法务直接显示时，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

                "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
