從Android向Google Cloud端點發送Firebase令牌

Question

我正在將Firebase身份驗證集成到我的Android應用中。成功登錄後，Android應用程序將調用在Google App Engine上運行的一些Google Cloud Endpoints。

因此，我需要將從身份驗證中收到的Firebase令牌傳遞給Google Cloud Endpoints。我使用下面的代碼來調用端點（source）

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

myApiService.sayHi(name).execute(); 

所以，我怎麼可以轉發令牌到我的後臺？

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();
