Question

官方文档中关于错误的说法是这样的：

注册令牌绑定到特定的一组发送者。客户端应用程序注册FCM时，必须指定允许哪些发件人发送消息。将消息发送到客户端应用程序时，应使用这些发件人ID之一。如果您切换到其他发送者，则现有的注册令牌将不起作用。

我确实在“ applicationServerKey”中指定了发件人，它是urlB64ToUint8Array（applicationServerPublicKey）。我从firebase控制台获取了公钥，并且在发送通知时，我使用的是firebase控制台中也提供的firebase服务器api密钥。

这是我注册客户端代码的一部分：

const applicationServerPublicKey = '<public key obtained from "web push certificates" inside firebase console -> cloud messaging>';
let swRegistration = null;

// Take the application server's public key which is base 64 URL safe encoded, and convert it to a UInt8Array as this is the expected input of the subscribe call.
function urlB64ToUint8Array(base64String) {
    const padding = '='.repeat((4 - base64String.length % 4) % 4);
    const base64 = (base64String + padding)
        .replace(/\-/g, '+')
        .replace(/_/g, '/');

    const rawData = window.atob(base64);
    const outputArray = new Uint8Array(rawData.length);

    for (let i = 0; i < rawData.length; ++i) {
        outputArray[i] = rawData.charCodeAt(i);
    }

    return outputArray;
}

// Register a Service Worker
if ('serviceWorker' in navigator && 'PushManager' in window) {
    navigator.serviceWorker.register(pageURL+'inc/js/serviceWorker.js')
    .then(function(swReg) {
        swRegistration = swReg;
    })
    .catch(function(error) {
        // ignore
    });
} else {
    // ignore
}

// Call the subscribe() method on service worker's pushManager
function subscribeUser() {
    const applicationServerKey = urlB64ToUint8Array(applicationServerPublicKey);
    swRegistration.pushManager.subscribe({
        userVisibleOnly: true,
        applicationServerKey: applicationServerKey
    })
    .then(function(subscription) {
        // user is subscribed
        updateSubscriptionOnServer(subscription, applicationServerKey);
        isSubscribed = true;
    })
    .catch(function(err) {
        // ignore
    });
}

我从firebase（端点，p256dh，auth）获得了响应，并将其存储在数据库中。这是我的PHP代码，用于稍后发送通知：

$registrationID = explode('/', $data['endpoint']);
$message = [
    'title' => 'Message title',
    'body' => 'This is sample notification'
];
$payload = [
    'registration_ids' => [end($registrationID)],
    'data' => $message
];
$headers = [
    'Authorization: key=' . FIREBASE_SERVER_KEY,
    'Content-Type: application/json'
];

$ch = curl_init('https://fcm.googleapis.com/fcm/send');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($payload));
$result = curl_exec($ch);
curl_close($ch);

var_dump($result);

使用

“ explode（'/'，$ data ['endpoint']））”是因为它包含从firebase返回的注册ID。端点响应如下所示：

https://fcm.googleapis.com/fcm/send/d-_yquqweTE:APA91bWKmKoWEXsyr5W0a8YnVdcm36BhB9Vh3ZbCMECGGxPJDOTYlQS9Zkh2Y7AdqdDcmB8S41eZ6nagR7dfBdvxyhuR3b8R2ilb8XH4wyKzbZQYzE-HH2b-R0cLdJcQ_vtR3AaISBz8

现在var_dump给出：

字符串（119） “ {” multicast_id“：6615023055114007195，”成功“：0，”失败“：1，” canonical_ids“：0，”结果“：[{”错误“：” MismatchSenderId“}]}”“

经过2天的反复试验后，我没有看到错误，请您能帮助我。谢谢！

从网络服务器发送推送通知时，Firebase错误“ MismatchSenderId”
