这里的技巧是我.env在我的工作区文件夹下： ${workspaceFolder}/.env，但vscode没有${workspaceFolder}用作我通过调用我的 go 函数来获取文件的当前工作目录。.envos.Getwd()

load_eng.go摘录如下：

curDir, err := os.Getwd()

if err != nil {

    log.Println(err)

}

loadErr := godotenv.Load(curDir + "/.env")

if loadErr != nil {

  log.Fatalln("can't load env file from current directory: " + curDir)

}

所以，我只需要通过在我的文件中$cwd添加来设置当前工作目录："cwd": "${workspaceFolder}"launch.json

"configurations": [

    {

      "name": "My Application",

      "type": "go",

      "request": "launch",

      "mode": "debug",

      "envFile": "${workspaceFolder}/.env",

      "program": "${workspaceFolder}/src/main.go",

      "cwd": "${workspaceFolder}"

    }

  ]
