从Android向Google Cloud端点发送Firebase令牌

Question

我正在将Firebase身份验证集成到我的Android应用中。成功登录后，Android应用程序将调用在Google App Engine上运行的一些Google Cloud Endpoints。

因此，我需要将从身份验证中收到的Firebase令牌传递给Google Cloud Endpoints。我使用下面的代码来调用端点（source）

MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(), 
       new AndroidJsonFactory(), null) 
myApiService = builder.build(); 

myApiService.sayHi(name).execute(); 

所以，我怎么可以转发令牌到我的后台？

您可以使用HttpRequestInitializer注入令牌：

HttpRequestInitializer requestInitializer = new HttpRequestInitializer() { 
    @Override 
    public void initialize(HttpRequest request) throws IOException { 
    HttpHeaders httpHeaders = new HttpHeaders(); 
    httpHeaders.setAuthorization("Bearer " + getFirebaseToken()); 
    request.setHeaders(httpHeaders); 
    } 
}; 

MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(), 
      new AndroidJsonFactory(), requestInitializer) 
myApiService = builder.build();
