Laravel Echo不会触发回调

我最近设置了Laravel应用程序并配置了Echo以接收Pusher Notifications。遗憾的是,即使接收到事件并且数据也随之触发,也不会触发回调函数。您可以在下面找到我的代码:

web.php

Route::get('/pusher', function() {
    $location = ['lang' => 'langTets', 'lat' => 'latTest'];
    event(new Freight\Events\LocationUpdated($location));
    return "Event has been sent!";
});

bootstrap.js

import Echo from 'laravel-echo'

window.Pusher = require('pusher-js');
Pusher.logToConsole = true;

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: 'iscorrect',
    cluster: 'eu',
    encrypted: true
});

window.Echo.channel('location-updates')
    .listen('.LocationUpdated', function(location) {
        console.log("Test");
    });

我的app.blade

<!DOCTYPE html>
<html lang="{{ app()->getLocale() }}">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!-- CSRF Token -->
    <meta name="csrf-token" content="{{ csrf_token() }}">

    <title>Freight</title>

    <!-- Styles -->
    <link href="{{ asset('css/app.css') }}" rel="stylesheet">
    <!-- JS -->
    <script src="{{ asset('js/app.js') }}"></script>
</head>
<body>
...

当我打开页面时,这会显示在我的控制台中:

app.js:32652 Pusher : State changed : initialized -> connecting
app.js:32652 Pusher : Connecting : {"transport":"ws","url":"censoredstuff"}
app.js:32652 Pusher : State changed : connecting -> connected with new socket ID morecensoredstuff
app.js:32652 Pusher : Event sent : {"event":"pusher:subscribe","data":{"channel":"location-updates"}}
app.js:32652 Pusher : Event recd : {"event":"pusher_internal:subscription_succeeded","data":{},"channel":"location-updates"}
app.js:32652 Pusher : No callbacks on location-updates for pusher:subscription_succeeded

现在,在触发事件时,这是控制台中显示的内容:

Pusher : Event recd : {"event":"Freight\\Events\\LocationUpdated","data":{"location":{"lang":"langTets","lat":"latTest"}},"channel":"location-updates"}
app.js:32652 Pusher : No callbacks on location-updates for Freight\Events\LocationUpdated

你有什么线索,为什么console.log无法正常工作?如果需要更多信息,请随时提出。

我仍然没有找出问题的根源。但是,这完全解决了它:

  • 在您的事件中实现方法broadcastAs(),如下所示:

broadcastAs(){ return 'myneweventname'; }

  • 更改.js文件,以便您正在侦听新创建的事件别名(没有前导句点)。
