我的Android客户端中的Google Cloud Endpoint身份验证：不允许受众，并且Oauth框架用户与oauth令牌用户不匹配

Question

I'm trying to access a deployed appengine backend api using OAuth2.0 support from my android client.

Authentication is working fine from the api explorer using the authorised email address

On the android side, I'm using the credentials/account picker method described here: https://developers.google.com/appengine/docs/python/endpoints/consume_android

But I get a 403 status code saying the access is forbidden and the following in the appengine log when accessing from an android client:

D 12:52:53.042 Checking for id_token.
W 12:52:53.046 Audience not allowed: 901326459160-vnpoik6ebefbnhtagqns7r0qlkt31gdo.apps.googleusercontent.com
D 12:52:53.047 Checking for oauth token.
D 12:52:53.049 Oauth framework user didn't match oauth token user.
I 12:52:53.050 Access rejected from none user.

What is happeing because the web app client id has been included in the whitelist for client ids and also the android client id?....

Answer 1

从该错误看来，您的应用程序正在传递不正确的用户令牌或后端API，这就是为什么它显示“ Oauth框架用户与Oauth令牌用户不匹配。我建议您检查在其中使用的clientID您在此页面上的“配置Android客户端以提供凭据”的代码，并查看客户端ID（Android）是否与开发者控制台中的相同

我想出了什么问题。...Web客户端电子邮件是作为端点Api方法中的访问者而不是Web客户端ID传递的
