这是我在使用Android my app设置CircleCI时遇到的错误。我认为这是因为我的回购中没有Google-Services.json文件！但出于安全考虑，我无法上传它。什么是解决此问题的最佳替代方法？

Answer 1

我遇到了完全相同的事情，这是我解决该问题的步骤。

1. 获取google-services.json的内容并对其进行base64编码。您可以像这样在powershell中进行操作：

   PS C:\Temp>$s = [System.Text.Encoding]::UTF8.GetBytes("contents of file pasted here")
   PS C:\Temp>[System.Convert]::ToBase64String($s)
   

   或使用这样的网站：https://www.base64encode.org/

2. 向您的CircleCI项目添加一个环境变量，其中键的值是步骤1中的base64编码的字符串。例如：

3. 在CircleCI congfig.yml中，添加以下命令，最好在顶部附近添加

   - run:
       # Export base64 encoded google-services.json
       # into local bash variables
       name: Export Google Services Json
       command: echo 'export GOOGLE_SERVICES_JSON="$GOOGLE_SERVICES_JSON"' >> $BASH_ENV
   - run:
       # Decode the base64 string
       name: Decode Google Services Json
       command: echo $GOOGLE_SERVICES_JSON | base64 -di > app/google-services.json
   

您可以从那里正常触发构建，并且可以运行。这基本上是在以安全的私有方式存储json，从而避免将其检入版本控制中。它将base64编码的CircleCI变量导出到构建服务器可用的bash变量。从那里将其解码为解码命令末尾指定位置的文件。这是google文档告诉您的放置位置。这是文档的链接：Firebase Docs

注意事项：

1. 如果您的google-services.json的内容发生了变化，则您将必须像步骤1中一样重新上传字符串。
