php - Laravel Echo 服务器在浏览器中没有响应
问题描述
我正在遵循https://medium.com/@dennissmink/laravel-echo-server-how-to-24d5778ece8b中给出的教程。
我安装了laravel-echo-server
, redis
, socket.io
, laravel-echo
.
这是配置laravel-echo-server init
{
"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": {},
"secureOptions": 67108864,
"sslCertPath": "",
"sslKeyPath": "",
"sslCertChainPath": "",
"sslPassphrase": "",
"subscribers": {
"http": true,
"redis": true
},
"apiOriginAllow": {
"allowCors": false,
"allowOrigin": "",
"allowMethods": "",
"allowHeaders": ""
}
}
app.blade.php
此js代码在所有页面的底部
<script type="module">
import Echo from 'laravel-echo'
window.io = require('socket.io-client');window.Echo = new Echo({
broadcaster: 'socket.io',
host: window.location.hostname + ':6001'
});
window.Echo.channel('test-event')
.listen('ExampleEvent', (e) => {
console.log(e);
});
</script>
我创建了一个事件php artisan make:event ExampleEvent
如下
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\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
class ExampleEvent implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
/**
* Create a new event instance.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Get the channels the event should broadcast on.
*
* @return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new Channel('test-event');
}
public function broadcastWith()
{
return [
'data' => 'Hi bro!'
];
}
}
和以下路线
Route::get('test-broadcast', function(){
broadcast(new \App\Events\ExampleEvent);
});
我还启动了一个队列监听器
php artisan queue:listen --tries=1
当我访问该页面时,test-broadcast
我在终端中看到了这个
但是浏览器的控制台什么也没有显示,而console.log(e);
必须返回一些东西。我也这样做了
window.Echo.channel('test-event')
.listen('ExampleEvent', (e) => {
alert('hi')
console.log(e);
});
但没有任何警报。听着好像有什么问题。
提前致谢。
更新
login
我在访问或任何页面包含时从浏览器控制台收到此错误app.blade.php
更新
我更新了脚本代码如下
<script src="http://{{ Request::getHost() }}:6001/socket.io/socket.io.js"></script>
<script src="{{ asset('/js/app.js') }}"></script>
<script type="module">
import Echo from 'laravel-echo'
window.Echo = new Echo({
broadcaster: 'socket.io',
host: window.location.hostname + ':6001'
});
window.Echo.channel('test-event')
.listen('.ExampleEvent', (e) => {
console.log(e);
});
</script>
控制台还是报错
TypeError:解析模块说明符时出错:laravel-echo
更新
我跑
npm run development -- --watch
这就是结果
cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js "--watch"
'cross-env' is not recognized as an internal or external command,

解决方案
总而言之,这是需要的:
- 默认 Laravel 安装
- 作曲家需要 predis/predis
- 安装 NPM 模块(laravel-echo-server、socket.io 和 laravel-echo)
通过控制台设置 Laravel Echo Server(大部分是默认设置,域名除外):
{ "authHost": "http://echo", "authEndpoint": "/broadcasting/auth", "clients": [ { "appId": "fc3de97a1787ea04", "key": "ecf31edced85073f7dd77de1588db13b" } ], "database": "sqlite", "databaseConfig": { "redis": {}, "sqlite": { "databasePath": "/database/laravel-echo-server.sqlite" } }, "devMode": true, "host": null, "port": "6001", "protocol": "http", "socketio": {}, "secureOptions": 67108864, "sslCertPath": "", "sslKeyPath": "", "sslCertChainPath": "", "sslPassphrase": "", "subscribers": { "http": true, "redis": true }, "apiOriginAllow": { "allowCors": true, "allowOrigin": "http://echo:80", "allowMethods": "GET, POST", "allowHeaders": "Origin, Content-Type, X-Auth-Token, X-Requested-With, Accept, Authorization, X-CSRF-TOKEN, X-Socket-Id" } }
设置 Redis 服务器并使用 Laravel broadcasting.php 文件连接到它
'default' => env('BROADCAST_DRIVER', 'redis')
或 .env 文件中的 BROADCAST_DRIVER=redis
- 在 web.php 中添加路由
Route::get('/test-broadcast', function(){
broadcast(new \App\Events\ExampleEvent);
return response('OK');
});
- 在 bootstrap.js 中添加代码:
从“laravel-echo”导入 Echo
window.io = require('socket.io-client');
window.Echo = new Echo({ 广播者:'socket.io',主机:window.location.hostname + ':6001' });
添加
window.Echo.channel('MyChannel') .listen('.ExampleEvent', (e) => { console.log(e); });
- 运行
npm run dev
编译所有 Javascript 模块 - 运行
laravel-echo-server start
以启动 Laravel Echo Server - 运行
php artisan queue:listen --tries=1
以启动监听队列 - 访问http://echo/test-broadcast
更新
11.1 将 ExampleEvent 的方法调整为:
public function broadcastOn() { return new Channel('MyChannel'); }
公共函数广播As(){返回'ExampleEvent'; }
11.2 在welcome.blade.php 中,在BODY 标签前,添加
<script type="text/javascript" src="/js/app.js"></script>
11.3 在database.php中,设置redix前缀为空字符串值
'prefix' => env('REDIS_PREFIX', '')
不要忘记重新运行npm run dev
并清除浏览器缓存
