Php 如何从web向应用程序发送FCM通知

我正在开发基于Firebase数据库和存储的聊天应用程序。一切正常，但现在我需要实现FCM，以便在应用程序处于后台或前台时在应用程序上接收通知。我找不到在PHP中实现的方法，PHP会监听firebase数据库中的任何更改，如果有任何更改，则向应用程序发送推送通知

有太多的代码从PHP发送通知，但没有一个是基于Firebase数据库的，甚至官方文档也有我的共享主机不支持的Node.js指南

我已经在我的应用程序端实现了FCM代码，这是从Firebase控制台测试的

这是我的Firebase数据库结构

发送推送通知只需向FCM服务器发送post请求即可

下面是一个工作示例：

$data = json_encode($json_data);
//FCM API end-point
$url = 'https://fcm.googleapis.com/fcm/send';
//api_key in Firebase Console -> Project Settings -> CLOUD MESSAGING -> Server key
$server_key = 'YOUR_KEY';
//header with content_type api key
$headers = array(
    'Content-Type:application/json',
    'Authorization:key='.$server_key
);
//CURL request to route notification to FCM connection server (provided by Google)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
if ($result === FALSE) {
    die('Oops! FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);

JSON付费负载的示例：

[
    "to" => 'DEVICE_TOKEN',
    "notification" => [
        "body" => "SOMETHING",
        "title" => "SOMETHING",
        "icon" => "ic_launcher"
    ],
    "data" => [
        "ANYTHING EXTRA HERE"
    ]
]

你可以用邮递员代替。 在chrome中打开Postman扩展并使用POST url

试试这段代码，它对我来说既适用于android，也适用于iOS

<?php
    $url = "https://fcm.googleapis.com/fcm/send";
    $token = "your device token";
    $serverKey = 'your server token of FCM project';
    $title = "Notification title";
    $body = "Hello I am from Your php server";
    $notification = array('title' =>$title , 'body' => $body, 'sound' => 'default', 'badge' => '1');
    $arrayToSend = array('to' => $token, 'notification' => $notification,'priority'=>'high');
    $json = json_encode($arrayToSend);
    $headers = array();
    $headers[] = 'Content-Type: application/json';
    $headers[] = 'Authorization: key='. $serverKey;
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST,"POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
    curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
    //Send the request
    $response = curl_exec($ch);
    //Close request
    if ($response === FALSE) {
    die('FCM Send Error: ' . curl_error($ch));
    }
    curl_close($ch);
?>

您可以不使用curl发送post请求（在我的服务器上不可用）

使用邮递员。：）你应该看看。特别是在.@AL.my服务器上，不支持从您的数据库中提取数据，并生成all@meda我有个问题。。。在这种情况下，如果要向ios设备发送通知，服务器密钥是什么？或者如何使用pem文件向ios设备发送通知？显示“Error=MissingRegistration”。您好，我已经学习了很多类似于您的示例，但我没有收到任何通知，即使CURL响应为肯定，也没有在firebase控制台中列出通知。。状态：200字符串（143）“{“multicast_id”：8573812091209374332，“success”：1，“failure”：0，“canonical_id”：0，“results”：[{“message_id:“0:1550852694105682%0762e9f8f9fd7ecd”}”，当我通过firebase控制台将它发送到它工作的相同设备令牌时，你知道吗？从firebase云获取设备令牌firestore@VishnuTasok我也犯了这个错误。如果你使用POSTMAN，你必须在正文中选择raw，然后从raw单选按钮旁边的下拉菜单中选择JSON（application/JSON）。然后它将覆盖您的标题。因此，即使您在header选项卡中输入了header，body选项卡中的错误设置也会在POSTMAN中覆盖您的header。应用程序端通知工作正常我通过FCM控制台检查了如何添加多个设备id或注册id以创建设备令牌数组$token=[“设备令牌\ 1”，“设备令牌\ 2”]或$token=array(“device_token_1”、“device_token_2”）感谢您的回复，我们需要将参数更改为“registration_ID”，否则将显示错误我认为变量名没有问题，但“registration_ID”是FCM的标准。谢谢@ShawkatAlam@RiajulIslamiam获取无效注册id错误获取错误：{“多播_id”：132596829075065854success“：0，“failure“：1，“canonical_id”：0，“results:[{”error:“InvalidParameters:请求中的数据字段不能包含重复的键。”}]}
