设置 launch.json 配置文件

实现效果

安装 delve

windows

go get -u github.com/go-delve/delve/cmd/dlv

linux

go get -u github.com/go-delve/delve/cmd/dlv

$ git clone https://github.com/go-delve/delve.git $GOPATH/src/github.com/go-delve/delve
$ cd $GOPATH/src/github.com/go-delve/delve
$ make install

GO15VENDOREXPERIMENT=1

OSX

$ go get -u github.com/go-delve/delve/cmd/dlv

执行上述代码前，确保你电脑上有编译工具

设置 launch.json 配置文件

ctrl+shift+pDebug: Open launch.jsonlaunch.json

{
	"version": "0.2.0",
	"configurations": [
		{
			"name": "Launch",
			"type": "go",
			"request": "launch",
			"mode": "auto",
			"program": "${fileDirname}",
			"env": {},
			"args": []
		}
	]
}

常见属性如下

在 debug 配置中使用 VS Code 变量

${workspaceFolder} 调试 VS Code 打开工作空间的根目录下的所有文件
${file} 调试当前文件
${fileDirname} 调试当前文件所在目录下的所有文件

使用构建标记(build tags)

buildFlags-tags=whatever_tag""-tags='first_tag second_tag third_tag'"

	"request": "launch",
	"mode": "test",
	"program": "${workspaceFolder}",
	"args": [
		"-test.run",
		"MyTestFunction"
	]
}

调试包中所有的测试用例配置片段

{
	"name": "Launch test package",
	"type": "go",
	"request": "launch",
	"mode": "test",
	"program": "${workspaceFolder}"
}

{
	"name": "Launch executable",
	"type": "go",
	"request": "launch",
	"mode": "exec",
	"program": "absolute-path-to-the-executable"
}

远程调试

Delve

$ dlv debug --headless --listen=:2345 --log --api-version=2

Delve

dlv debug --headless --listen=:2345 --log -- -myArg=123

launch.json

{
	"name": "Launch remote",
	"type": "go",
	"request": "launch",
	"mode": "remote",
	"remotePath": "服务器调试文件的目录（绝对路径）",
	"port": 2345,
	"host": "127.0.0.1",
	"program": "本地调试文件所在的目录（绝对路径）",
	"env": {}
