安卓 :What is the difference between app signing certificate and upload certificate?

Question

应用签名证书和上传证书有什么区别？
我在将 Google Play 游戏与我的应用程序集成时遇到了问题(我将此作为另一个问题发布)，我注意到用于在 Google API 控制台上自动生成的客户端 ID 的那个称为签名证书。
但是，当我在 Android Studio 上运行登录报告时可以看到的内容称为上传证书。

应该为客户 ID 设置哪一个？顺便说一句，两者都没有解决我的问题，但我很好奇其中的区别。

签署证书

Certain Google Play services (such as Google Sign-in and App Invites) require you to provide the SHA-1 of your signing certificate so we can create an OAuth2 client and API key for your app. For more info refer:doc

上传证书

When you publishing an app that is not signed by an upload key, the Google Play Console provides the option to register one for future updates to the app. Although this is an optional step, it’s recommended that you publish your app with a key that’s separate from the one Google Play uses to distribute your app to users. That way, Google keeps your signing key secure, and you have the option to reset a lost or compromised private upload key. This section describes how to create an upload key, generate an upload certificate from it, and register that certificate with Google Play for future updates of your app. For more info refer:doc
