本文介绍了如何通过使用FCM而不使用XMPP或任何其他脚本将设备发送到设备通知？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我知道XMPP服务器可以接收上游消息并将通知发送给其他设备。要接收使用上游API发送的消息，我需要实现一个XMPP服务器，但是还有其他方法吗？
：包含两个库。
compile'com.squareup.okhttp3：okhttp： 3.4.1'
compile'com.google.firebase：firebase-messaging：9.2.0'
第二步：在您的MainActivity或您想要发送通知的地方。
OkHttpClient mClient = new OkHttpClient（）;
String refreshedToken =; //添加使用firebase登录的用户刷新标记。
JSONArray jsonArray = new JSONArray（）;
jsonArray.put（refreshedToken）;
第3步：创建一个向所有设备发送通知的异步任务。
public void sendMessage（final JSONArray recipients，final String title，final String body，final String icon，final String message） b
$ b新的AsyncTask< String，String，String>（）{
@Override
保护字符串doInBackground（String ... params）{
try {
JSONObject root = new JSONObject（）;
JSONObject notification = new JSONObject（）;
notification.put（body，body）;
notification.put（title，title）;
notification.put（icon，icon）;
JSONObject data = new JSONObject（）;
data.put（message，message）;
root.put（通知，通知）;
root.put（data，data）;
root.put（registration_ids，收件人）;
String result = postToFCM（root.toString（））;
Log.d（主要活动，结果：+结果）;
返回结果;
catch（Exception ex）{
ex.printStackTrace（）;
}
返回null;
$ b @Override
保护无效onPostExecute（字符串结果）{
尝试{
JSONObject resultJson = new JSONObject（result）;
int成功，失败;
success = resultJson.getInt（success）;
failure = resultJson.getInt（failure）;
Toast.makeText（MainActivity.this，Message Success：+ success +Message Failed：+ failure，Toast.LENGTH_LONG）.show（）;
} catch（JSONException e）{
e.printStackTrace（）;
Toast.makeText（MainActivity.this，Message Failed，Unknown error occurred，Toast.LENGTH_LONG）.show（）;
}
}
} .execute（）;
字符串postToFCM（String bodyString）抛出IOException {
public static final String FCM_MESSAGE_URL =https：// fcm .googleapis.com / FCM /发送;
final MediaType JSON
= MediaType.parse（application / json; charset = utf-8）;
RequestBody body = RequestBody.create（JSON，bodyString）;
Request request = new Request.Builder（）
.url（Url.FCM_MESSAGE_URL）
.post（body）
.addHeader（Authorization，key =+你的服务器密钥）
.build（）;
响应响应= mClient.newCall（request）.execute（）;
return response.body（）。string（）;
第四步：通过点击按钮
btnSend.setOnClickListener（new View.OnClickListener（）{
@Override
public void onClick（View v）{
sendMessage（jsonArray，Hello，How ru，Http：\\google.com，My Name is Vishal）;
}
} ）;
Is there any way to send Upstream notification message through FCM from one android device to another devices connected with Firebase database.
I know that XMPP server can then receive the upstream messages and send the notifications to the other devices.To receive messages sent with the upstream API i need to implement an XMPP server but there is any other way???
解决方案
After lots of try finally i got one solution and its work perfectly
Step 1 :Include two library.
compile 'com.squareup.okhttp3:okhttp:3.4.1' compile 'com.google.firebase:firebase-messaging:9.2.0'
Step 2 : In your MainActivity or from where you want to send notifications.
OkHttpClient mClient = new OkHttpClient();
String refreshedToken = "";//add your user refresh tokens who are logged in with firebase.
JSONArray jsonArray = new JSONArray();
jsonArray.put(refreshedToken);
Step 3: Create one async task which sends notifications to all devices.
public void sendMessage(final JSONArray recipients, final String title, final String body, final String icon, final String message) {
new AsyncTask<String, String, String>() {
@Override
protected String doInBackground(String... params) {
try {
JSONObject root = new JSONObject();
JSONObject notification = new JSONObject();
notification.put("body", body);
notification.put("title", title);
notification.put("icon", icon);
JSONObject data = new JSONObject();
data.put("message", message);
root.put("notification", notification);
root.put("data", data);
root.put("registration_ids", recipients);
String result = postToFCM(root.toString());
Log.d("Main Activity", "Result: " + result);
return result;
} catch (Exception ex) {
ex.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
try {
JSONObject resultJson = new JSONObject(result);
int success, failure;
success = resultJson.getInt("success");
failure = resultJson.getInt("failure");
Toast.makeText(MainActivity.this, "Message Success: " + success + "Message Failed: " + failure, Toast.LENGTH_LONG).show();
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(MainActivity.this, "Message Failed, Unknown error occurred.", Toast.LENGTH_LONG).show();
}
}
}.execute();
}
String postToFCM(String bodyString) throws IOException {
public static final String FCM_MESSAGE_URL = "https://fcm.googleapis.com/fcm/send";
final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");
RequestBody body = RequestBody.create(JSON, bodyString);
Request request = new Request.Builder()
.url(Url.FCM_MESSAGE_URL)
.post(body)
.addHeader("Authorization", "key=" + "your server key")
.build();
Response response = mClient.newCall(request).execute();
return response.body().string();
}
Step 4 : Call in onclick of your button
btnSend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
sendMessage(jsonArray,"Hello","How r u","Http:\\google.com","My Name is Vishal");
}
});
