将 Firebase 令牌从 Android 发送到 Google Cloud Endpoints

Question

我正在将 Firebase 身份验证集成到我的 Android 应用中。登录成功后，Android App 会调用一些运行在 Google App Engine 上的 Google Cloud Endpoints。

所以我需要将从身份验证收到的 Firebase 令牌传递给 Google Cloud Endpoints。我正在使用以下代码调用端点 (source)

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

myApiService.sayHi(name).execute();

那么如何将令牌转发到我的后端？

Answer 1

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();
