vscode 中未检测到 env 文件

Question

我有一个my-project多根工作区：

\n

- my-project\n   - my-project-api-gateway\n   - another-root-folder-we-dont-care-about\n

\n

这是我的launch.json配置文件my-project-api-gateway

\n

- my-project\n   - my-project-api-gateway\n   - another-root-folder-we-dont-care-about\n

\n

调试控制台输出

\n

这里的技巧是 my.env位于我的工作区文件夹下： ${workspaceFolder}/.env但是delve不用作${workspaceFolder}当前工作目录，这就是我用来从这里os.Getwd()获取的原因.env。

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)
}

因此，我只需在文件中$cwd添加以下内容来设置当前工作目录："cwd": "${workspaceFolder}"launch.json

"configurations": [
    {
      "name": "My Application",
      "type": "go",
      "request": "launch",
      "mode": "debug",
      "envFile": "${workspaceFolder}/.env",
      "program": "${workspaceFolder}/src/main.go",
      "cwd": "${workspaceFolder}"
    }
  ]
