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 应用程序中。成功登录后，Android 应用程序将在 Google App Engine 上调用一些 Google 云端点 运行。

所以我需要将从身份验证收到的 Firebase 令牌传递给 Google 云端点。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();
