## 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

                "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
