从Android向Google云终端发送Firebase令牌 [英] Send Firebase Token from Android to Google Cloud Endpoints

问题描述

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应用程序将调用Google App Engine上运行的一些Google Cloud Endpoints。

$ b 因此，我需要将通过身份验证收到的Firebase令牌传递给Google云终端。我正在使用以下代码来调用端点（ source a>）
$ b $ pre $ MyApi.Builder builder = new MyApi.Builder（AndroidHttp.newCompatibleTransport（），$ b $ new AndroidJsonFactory ），null）
myApiService = builder.build（）;

myApiService.sayHi（name）.execute（）;


那么我怎样才能将令牌转发给我的后端呢？

HttpRequestInitializer 注入令牌：

  HttpRequestInitializer requestInitializer = new HttpRequestInitializer（）{
 @Override $ b $ 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（）; 
  

I am integrating Firebase Authentication into my Android App. After successful login, the Android App will call some Google Cloud Endpoints running on Google App Engine.

So I need to pass the Firebase Token I received from the Authentication to the Google Cloud Endpoints. I am using the following code to call the endpoints (source)

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

myApiService.sayHi(name).execute();

So how can I forward the token to my backend?

解决方案

You can use an HttpRequestInitializer to inject the token:

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();
