专用频道无法与Laravel回显服务器一起使用 [英] Private channel not working with Laravel echo server
问题描述
我在控制台上收到此JS错误:
I'm getting this JS error on the console:
app.js:167未捕获的ReferenceError:未定义receiveId
app.js:167 Uncaught ReferenceError: receiverId is not defined
这是我完整的代码:
PrivateChatController:
event(new PrivateMessageEvent($chat, $receiverId));
PrivateMessageEvent:
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use App\User;
use App\PrivateChat;
class PrivateMessageEvent implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $privateChat, $receiverId;
/**
* Create a new event instance.
*
* @return void
*/
public function __construct(PrivateChat $privateChat, $receiverId)
{
$this->privateChat = $privateChat;
$this->receiverId = $receiverId;
}
/**
* Get the channels the event should broadcast on.
*
* @return Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel('private-chat.' . $this->receiverId);
}
}
Bootstrap.js
import Echo from "laravel-echo"
window.Echo = new Echo({
broadcaster: 'socket.io',
host: window.location.hostname + ':6001'
});
window.Echo.private(`private-chat.${receiverId}`)
.listen('PrivateMessageEvent', (e) => {
console.log(e);
});
channels.php
Broadcast::channel('private-chat.{receiverId}', function ($user, $receiverId) {
return true; // this is just for debugging to allow anyone to listen on this channel
//return $user->id === $receiverId;
});
laravel-echo-server.json
{
"authHost": "http://localhost",
"authEndpoint": "/broadcasting/auth",
"clients": [],
"database": "redis",
"databaseConfig": {
"redis": {},
"sqlite": {
"databasePath": "/database/laravel-echo-server.sqlite"
}
},
"devMode": true,
"host": null,
"port": "6001",
"protocol": "http",
"socketio": {},
"sslCertPath": "",
"sslKeyPath": ""
}
在后台 queue:work 和 laravel-echo-server 已在运行
在触发该事件时,我正在laravel-echo-server控制台上收到此消息:
Upon firing that event, I'm getting this message on the laravel-echo-server console:
Channel: private-private-chat.
Event: App\Events\PrivateMessageEvent
CHANNEL private-private-chat.
注释:
-
我可以成功收听公共频道.私人频道的唯一问题.
I'm successfully able to listen to the public channel. The only issue with the private channel.
使用最新的Laravel版本,即5.4
Using latest Laravel version i.e 5.4
我已经按照官方文档做了所有事情:
I have done all the things as per the official docs:
https://laravel.com/docs/master/广播
https://github.com/tlaverdure/laravel-echo-server
我也在github repo上提出了问题:
I have also raised issue on github repo:
https://github.com/tlaverdure/laravel-echo-server /issues/158
我花了十多个小时,尽我所能,但没有运气.
I have spent more than 10 hours and tried everything I could, but no luck.
谢谢
推荐答案
尝试更改此行:
$this->$receiverId = $receiverId;
此行:
$this->receiverId = $receiverId;
在您的PrivateMessageEvent __construct()
In your PrivateMessageEvent __construct()
更新:
尝试使用像这样的固定频道ID:
Try to use use a fixed channel id like this:
window.Echo.private('private-chat.1')
我建议您也使用状态显示频道,它也是私有的,但具有更多功能,即:
I suggest you also to use presence channel, are private too but with more features, i.e.:
Echo.join('private-chat.1')
.listen('PrivateMessageEvent', (e) => {
console.log(e);
});
如果您使用的是动态频道编号,即:
If you use a dinamic channel number like you use, i.e.:
window.Echo.private(`private-chat.${receiverId}`)
您必须在JavaScript中为receiverId
赋一个值,该声明是一个通用的房间侦听器,但应定义receiveId,$ {receiverId}是字符串插值.
You have to give receiverId
a value in javascript, this declaration is a generic room listener but receiverId should be defined, ${receiverId} is a string interpolation.
例如,可以使用刀片语法在加入app.js之前在模板中定义接收器ID:
You can define receiverId in the template before inluding app.js, for example, using blade syntax:
<script>
receiverId = {{ $receiverId }};
</script>
另一种想法:我想清楚一点,在以上所有代码中,receiverId代表客户端希望加入的聊天室的ID,而不是接收用户的ID.
Another think: I want to be clear that, in all the code above, receiverId represent the id of the chat/room a client want join to not the ID of the receiving user.
