我正在尝试使用laravel-echo-server(socket.io),但遇到了一个障碍,即客户端似乎没有收到任何广播的事件。
一切似乎都正常连接,socket.io服务器报告它正在连接并授权用户,但是当我广播消息时似乎什么也没发生。该事件出现在Laravel Horizon上,但除此之外,什么也没有发生。这是我的代码:
server.js运行laravel-echo-server:
require('dotenv').config();
const env = process.env;
require('laravel-echo-server').run({
authHost: env.APP_URL,
devMode: env.APP_DEBUG,
database: "redis",
databaseConfig: {
redis: {
host: env.REDIS_HOST_PUBLIC,
port: env.REDIS_PORT,
}
}
});
我在channel.php中的频道
Broadcast::channel('message.pushed', function () {
return true;
});
我的活动:
<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Contracts\Broadcasting\ShouldBroadcastNow;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
class MessagePushed implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $message;
/**
* Create a new event instance.
*
* @return void
*/
public function __construct()
{
$this->message = "My New Message";
}
/**
* Get the channels the event should broadcast on.
*
* @return Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel('message.pushed');
}
}
我在app.js中的事件监听器
import Echo from 'laravel-echo';
window.io = require('socket.io-client');
if (typeof io !== 'undefined') {
var token = $('meta[name="_token"]').attr('content')
window.Echo = new Echo({
auth : {
headers: {
Authorization: `Bearer ${token}`,
},
},
broadcaster: 'socket.io',
host : window.location.hostname + ':6001',
});
}
function listenForBroadcast() {
Echo.private('message.pushed')
.listen('MessagePushed', (e) => {
console.log(e)
console.log("Listened")
});
}
listenForBroadcast();
最后发送邮件的路线:
Route::get('/event-test', function () {
broadcast(new App\Events\MessagePushed());
});
我不太确定自己哪里出了问题,或者为什么客户什么也没捡到。
在laravel-echo-server中查看时,命令行在回显:
Channel: laravel_database_private-message.pushed
Event: App\Events\MessagePushed
答案 0 :(得分:0)
在浏览器中,您需要像Redis一样监听Channel,也要像redis那样监听事件,因此更改listenForBroadcast()方法可能会有所帮助。 在代码中,通道名称从message.pushed更改为laravel_database_private-message.pushed,事件名称从MessagePushed更改为.App \ Events \ MessagePushed(不要错过App的点前缀)
function listenForBroadcast() {
Echo.private('laravel_database_private-message.pushed')
.listen('.App\\Events\\MessagePushed', (e) => {
console.log(e)
console.log("Listened")
});
}
我根据以下链接中给出的解决方案尝试了此解决方案,它对我有用 laravel Echo does not listen to channel and events
