问题

我有一个名为my-project的多根工作区：

  1. - my-project
  2.    - my-project-api-gateway
  3.    - another-root-folder-we-dont-care-about

这是我针对my-project-api-gateway的launch.json配置文件：

  1. {
  2.   // 请参阅 https://code.visualstudio.com/docs/editor/debugging#_launchjson-attributes
  3.   // 和这里的变量 https://code.visualstudio.com/docs/editor/variables-reference
  4.   "version": "0.2.0",
  5.   "configurations": [
  6.     {
  7.       "name": "my-project-api-gateway",
  8.       "type": "go",
  9.       "request": "launch",
  10.       "mode": "debug",
  11.       "envFile": "${workspaceFolder}/.env", ----> 加载 .env 文件时出错
  12.       "program": "${workspaceFolder}/src/main.go"
  13.     }
  14.   ]
  15. }

答案1

得分: 2

这里的技巧是，我的 .env 文件位于工作空间文件夹下：${workspaceFolder}/.env，但是 delve 不使用 ${workspaceFolder} 作为 当前工作目录，所以我使用 os.Getwd() 来获取这里的 .env 文件。

load_eng.go 的代码片段如下：

  1. curDir, err := os.Getwd()
  2. if err != nil {
  3. 	log.Println(err)
  4. }
  5. loadErr := godotenv.Load(curDir + "/.env")
  6. if loadErr != nil {
  7.   log.Fatalln("无法从当前目录加载环境文件：" + curDir)
  8. }

因此，我只需要在我的 launch.json 文件中添加 "cwd": "${workspaceFolder}" 来设置当前工作目录 $cwd：

  1. "configurations": [
  2.     {
  3.       "name": "My Application",
  4.       "type": "go",
  5.       "request": "launch",
  6.       "mode": "debug",
  7.       "envFile": "${workspaceFolder}/.env",
  8.       "program": "${workspaceFolder}/src/main.go",
  9.       "cwd": "${workspaceFolder}"
  10.     }
  11.   ]

英文:

The trick here is that my .env is under my workspace folder: ${workspaceFolder}/.env, but delve doesn't use ${workspaceFolder} as the current working directory that why I'm using os.Getwd() to fetch the .env from here.

load_eng.go excerpt below:

  1. curDir, err := os.Getwd()
  2. if err != nil {
  3. 	log.Println(err)
  4. }
  5. loadErr := godotenv.Load(curDir + &quot;/.env&quot;)
  6. if loadErr != nil {
  7.   log.Fatalln(&quot;can&#39;t load env file from current directory: &quot; + curDir)
  8. }

So, I just had to set the current working directory $cwd by adding &quot;cwd&quot;: &quot;${workspaceFolder}&quot; in my launch.json file:

  1. &quot;configurations&quot;: [
  2.     {
  3.       &quot;name&quot;: &quot;My Application&quot;,
  4.       &quot;type&quot;: &quot;go&quot;,
  5.       &quot;request&quot;: &quot;launch&quot;,
  6.       &quot;mode&quot;: &quot;debug&quot;,
  7.       &quot;envFile&quot;: &quot;${workspaceFolder}/.env&quot;,
  8.       &quot;program&quot;: &quot;${workspaceFolder}/src/main.go&quot;,
  9.       &quot;cwd&quot;: &quot;${workspaceFolder}&quot;
  10.     }
  11.   ]
