无法从本地服务器

我正在使用localhost开发firebase通知演示。

我使用android studio配置firebase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android开发人员所以我不知道php api。我认为这可能是send_ntification.php文件中的一个问题。

但我测试使用firebase控制台它工作正常。

以下是我的 php文件

的init.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>

</form>

</body>

这是我的安卓代码

FcmInstenceIdService.java

    @Override
    public void onTokenRefresh() {

        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();
    }
}

FcmMessagingService.java

我不明白问题在哪里请帮助我。任何帮助将非常感谢。我花了3个小时来寻找解决方案。

答案 0 :(得分：1)

嗯，我遇到了与FCM相同的问题，因为服务器密钥和旧服务器密钥之间存在一点误解。

  • 对于FCM，请始终使用服务器密钥。由于其长度，我们通常会采用旧服务器密钥;我们在GCM中使用了这个简短的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;我们从未在后端使用发件人ID 用于GCM。

请按照以下两个步骤操作，希望您能收到来自FCM的推送通知。
