Firebase 通知未从本地服务器接收

我正在开发使用本地主机的Firebase通知演示。

我使用 android studio 配置火碱库并将服务器密钥添加到我的 php 文件中，我在我的 Phpmyadmin(Wamp 服务器)中获得了令牌，但是当我使用 html 文件发送通知时，我无法收到通知。

我是安卓开发人员，所以我不知道php api。我认为这可能是send_ntification.php文件中的问题。

但是我使用Firebase控制台进行了测试，它工作正常。

这是我的php 文件

初始化.php

<?php
$host = "localhost";
$db_user = "root";
$db_password = "";
$db_name = "fcm_db";
$con = mysqli_connect($host,$db_user,$db_password,$db_name);
if($con)
echo "Connection Success";
else
echo"Connection Error....."; 
?>

fcm_insert.php

<?php
require "init.php";
$fcm_token = $_POST["fcm_token"];
$sql = "insert into fcm_info values('".$fcm_token."');";
mysqli_query($con,$sql);
mysqli_close($con)
?>

send_notification.php

<?php
include_once("init.php");
$message =$_POST['message'];
$title = $_POST['title'];
$path_to_fcm = "https://fcm.googleapis.com/fcm/send";
$server_key = "MY SERVER KEY";
$sql = "select fcm_token from fcm_info";
$result = mysqli_query($con,$sql);
$row = mysqli_fetch_row($result);
$key = $row[0];

$headers = array(
'Authorization:key=' .$server_key,
'Content-Type:application/json'
);

$fields = array('to'=>$key,
'notification'=>array('title'=>$title,'body'=>$message));
$payload = json_encode($fields);
$curl_session = curl_init();
curl_setopt($curl_session, CURLOPT_URL, $path_to_fcm);
curl_setopt($curl_session, CURLOPT_POST, true);
curl_setopt($curl_session, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl_session, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_session, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_session, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
curl_setopt($curl_session, CURLOPT_POSTFIELDS, $payload);
$result = curl_exec($curl_session);
curl_close($curl_session);
mysqli_close($con);
?>

send_notificatiion.html

<html>
<body>
<form action="send_notification.php" method="post">
<table>
<tr>
<td> Title : </td> <td><input type="text" name="title"/></td>
<tr>
<tr>
<td>Message : <td><td><input type="text" name="message"/></td>
</tr>
<td><input type="submit" value="submit"/></td>
</tr>
</table>

这是我的安卓代码

FcmInstenceIdService.java

public class FcmInstenceIdService extends FirebaseInstanceIdService {

@Override

String recent_token = FirebaseInstanceId.getInstance().getToken();
Log.e(TAG, "onTokenRefresh: token = "+recent_token );
SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(getString(R.string.FCM_PREF), Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString(getString(R.string.FCM_TOKEN),recent_token);
editor.apply();
}
}

Fcm消息服务.java

notificationManager.notify(0,builder.build());

我不明白问题在哪里，请帮助我。任何帮助将不胜感激。我花了3个小时来寻找解决方案。

好吧，由于服务器密钥和旧版服务器密钥之间的一些误解，我在 FCM 中遇到了同样的问题。

对于 FCM，请始终使用服务器密钥。我们错误地使用旧版服务器密钥，因为它的长度;我们在GCM中使用了那个简短的Web API密钥。
您需要在后端系统中使用发件人ID 才能发送推送通知;我们从未在 GCM 的后端中使用发件人ID。

按照这两个步骤操作，希望您能收到FCM的推送通知。
