Question

我想在不使用Firebase控制台的情况下发送通知（我想在服务器端制作）。为此，我正在尝试将设备令牌ID发送到Web服务。我在这个Android项目中使用Firebase Cloud Messaging。我怎么能这样做？

public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService{

    private static final String TAG = "MyFirebaseIIDService";

    @Override
    public void onTokenRefresh() {
        String token = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Token: " + token);

        sendRegistrationToServer(token);
    }

    private void sendRegistrationToServer(String token) {
        // send token to web service ??

    }

谢谢！

Answer 1

首先，您应该运行一些服务器来接收令牌和存储。然后，您可以从应用程序进行API调用，以将FCM令牌发布到您的服务器。

Answer 2

1）创建firebase ref像这样

    private void sendRegistrationToServer(String token) {
            // send token to web service ??   
        final FirebaseDatabase database = FirebaseDatabase.getInstance();
        DatabaseReference ref = database.getReference("server/saving-data/IDs");
        // then store your token ID
        ref.push().setvalue(token)
    }

将以下给出的代码粘贴到您的类中，此方法将自动从“onTokenRefresh（）”方法执行。只需确保使用您自己的服务器的Web服务URL替换Web服务URL。

private void sendRegistrationToServer(String deviceToken) {

class SendPostReqAsyncTask extends AsyncTask<String, Void, String> {

    @Override
    protected String doInBackground(String... params) {
        String deviceToken = params[0];



        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(
            "http://lib-dm.process9.com/libertydm/ValidateUserHandler.ashx");// replace with your url
        httpPost.addHeader("Content-type",
            "application/x-www-form-urlencoded");
        BasicNameValuePair usernameBasicNameValuePair = new BasicNameValuePair(
            "UserId", paramUsername);  // Make your own key value pair
        BasicNameValuePair passwordBasicNameValuePAir = new BasicNameValuePair(
            "Password", paramPassword);// make your own key value pair

        // You can add more parameters like above

        List<NameValuePair> nameValuePairList = new ArrayList<NameValuePair>();
        nameValuePairList.add(usernameBasicNameValuePair);
        nameValuePairList.add(passwordBasicNameValuePair);

        try {
            UrlEncodedFormEntity urlEncodedFormEntity = new UrlEncodedFormEntity(
                nameValuePairList);
            httpPost.setEntity(urlEncodedFormEntity);

            try {
                HttpResponse httpResponse = httpClient
                    .execute(httpPost);
                InputStream inputStream = httpResponse.getEntity()
                    .getContent();
                InputStreamReader inputStreamReader = new InputStreamReader(
                    inputStream);
                BufferedReader bufferedReader = new BufferedReader(
                    inputStreamReader);
                StringBuilder stringBuilder = new StringBuilder();
                String bufferedStrChunk = null;
                while ((bufferedStrChunk = bufferedReader.readLine()) != null) {
                    stringBuilder.append(bufferedStrChunk);
                }

                return stringBuilder.toString();

                } catch (ClientProtocolException cpe) {
                    System.out
                        .println("First Exception coz of HttpResponese :"
                            + cpe);
                    cpe.printStackTrace();
                } catch (IOException ioe) {
                    System.out
                        .println("Second Exception coz of HttpResponse :"
                            + ioe);
                    ioe.printStackTrace();
                }

        } catch (UnsupportedEncodingException uee) {
            System.out
                .println("An Exception given because of UrlEncodedFormEntity argument :"
                    + uee);
            uee.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
    }
}

SendPostReqAsyncTask sendPostReqAsyncTask = new SendPostReqAsyncTask();
sendPostReqAsyncTask.execute(token);
}
