GoogleAuthException:使用Cloud Endpoints进行身份validation时未知

我正在尝试向我的Cloud Endpoints添加身份validation,但我无法让它工作。 我正在使用此博客作为指南: http : //devthots.blogspot.nl/2012/07/building-awesome-android-apps-with.html

我拥有的:

在AppEngine项目中:

@Api(name = "noteendpoint", clientIds = { "123456789012-abcdefghijklmnopqrstuvwxyz012345.apps.googleusercontent.com" }, audiences = { "my_project_id.appspot.com" }, namespace = @ApiNamespace(ownerDomain = "example.com", ownerName = "example.com", packagePath = "myapp")) public class NoteEndpoint { // Rest of class, added parameter User to all methods. } 

在我的Android应用项目中:

 Note note = new Note(); note.setDescription("Description!"); GoogleAccountCredential credential = GoogleAccountCredential.usingAudience(MainActivity.this, "my_project_id.appspot.com"); credential.setSelectedAccountName(ACCOUNT_NAME); note.setEmailAddress(credential.getSelectedAccountName()); Builder endpointBuilder = new Noteendpoint.Builder( AndroidHttp.newCompatibleTransport(), new JacksonFactory(), credential); Noteendpoint endpoint = CloudEndpointUtils.updateBuilder(endpointBuilder).build(); Note result = endpoint.insertNote(note).execute(); // Exception thrown 

当我运行它时,抛出一个GoogleAuthException: Unknown

我怎么解决这个问题?

用于NoteEndpoint类的clientId是从“已安装应用程序的客户端ID”复制的,其中包含调试密钥sha1。

使用GoogleAccountCredential.usingAudience(MainActivity.this, "server:client_id:my_project_id.appspot.com"); (所以使用server:client_id: prefixed)没有帮助。

生成Android客户端ID时要小心。 输入包名称时,请使用app / build.gradle中编写的应用程序ID。 它可能与您的源类的包不同。

说明:

在项目创建时,您输入的包名称由Android用作应用程序ID,用于为源类生成包。 在项目开发期间,您可以更改源类的包名称。 但要小心,Android Studio不会自动更改您的应用程序ID!

运用

 GoogleAccountCredential credential = GoogleAccountCredential.usingAudience(MainActivity.this, "server:client_id:12312312312-abcdefghijklmnopqrstuvw012345678.apps.googleusercontent.com"); 

 @Api(name = "noteendpoint", clientIds = { Ids.WEB_CLIENT_ID, Ids.ANDROID_CLIENT_ID }, audiences = { Ids.ANDROID_AUDIENCE }, namespace = @ApiNamespace(ownerDomain = "example.com", ownerName = "example.com", packagePath = "test")) public class NoteEndpoint { public class Ids { public static final String WEB_CLIENT_ID = "12312312312312-abcdefghijklmnopqrstuvwxyz012345678.apps.googleusercontent.com"; public static final String ANDROID_CLIENT_ID = "12312312312312-0123456789abcdefghabcdefghabcdefgha.apps.googleusercontent.com"; public static final String ANDROID_AUDIENCE = WEB_CLIENT_ID; } 

解决了这个问题。
