Laravel广播-无需承载令牌即可访问的私人频道

Question

我有安装插座。io与laravel echo一起加入并收听laravel广播频道。公共频道工作正常，因为它们不需要任何授权。专用通道未按预期工作，我可以使用套接字加入任何专用通道。未传递授权令牌的io客户端。

插座io客户端

window.Echo = new Echo({
    host: "http://127.0.0.1:6001",
    auth:{
        headers: {
            Accept: 'application/json',
            Authorization: 'Bearer ',
        },
    },
    broadcaster: 'socket.io',
});

window.Echo.private('user'+"."+userid)
.listen('Notification', (e) => {
    console.log(e);
})

Laravel Echo服务器配置

{
"authHost": "http://127.0.0.1:8000",
"authEndpoint": "/broadcasting/auth",
"clients": [],
"database": "redis",
"databaseConfig": {
    "redis": {
        "port": "6379",
        "host": "localhost"
    },
    "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": "localhost",
    "allowMethods": "GET, POST",
    "allowHeaders": "Origin, Content-Type, X-Auth-Token, X-Requested-With, Accept, Authorization, X-CSRF-TOKEN, X-Socket-Id"
}
}

航道

Broadcast::channel('user.{userId}', function ($user, $userId) {
    return (int) $user->id === (int) $userId;
});

广播服务提供商

Broadcast::routes(['middleware' => ['auth:api']]);

用户配置

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'passport',
        'provider' => 'users',
        'hash' => false,
    ],
],

127.0.0.1:8000/无令牌访问时的广播/授权响应

{"message":"Unauthenticated."}

Laravel回声服务器

[4:50:17 PM] - Preparing authentication request to: http://127.0.0.1:8000
[4:50:17 PM] - Sending auth request to: http://127.0.0.1:8000/broadcasting/auth
[4:50:17 PM] - LtnbMInYDGa_QMMcAAAA authenticated for: private-user.1
[4:50:17 PM] - LtnbMInYDGa_QMMcAAAA joined channel: private-user.1

所以我猜laravel echo服务器在响应“未经验证”时不会返回false

任何帮助都将不胜感激

Answer 1

好吧，这很有趣。我决定检查laravel echo服务器如何请求“广播/授权”，以及它如何处理该请求的响应。

您可以在这里查看：https://github.com/tlaverdure/laravel-echo-server/blob/master/src/channels/private-channel.ts

因此laravel-echo-server返回true如果广播/授权的响应代码是200，返回false如果响应代码不是200或如果有一个错误的请求。

这里的问题是，当您向通过passport身份验证处理的laravel api路由发送请求时，它确实返回“Unauthenticated”消息，但没有401代码，因此laravel echo服务器认为请求成功，并允许用户加入该通道。

解决方案：

1. 返回401代码和Passport未经验证的响应
2. 通道认证中间件

返回401代码与护照未经验证的响应

projectdir\app\Exceptions处理程序。php

...
use Illuminate\Auth\AuthenticationException;

...
public function render($request, Exception $exception)
{
    if($exception instanceof AuthenticationException){
        return response()->json(['message' => $exception->getMessage()], 401);
    }else{
        return response()->json(['message' => $exception->getMessage() ]);
    }

    return parent::render($request, $exception);
}

用于通道认证的中间件

php artisan make:中间件[名称]

Projectdir\app\Http\Middleware[name]. php

use Closure;
use Illuminate\Support\Facades\Auth;

class SocketAuth
{

    public function handle($request, Closure $next)
    {
        $user = Auth::User();

        if($user !== null){
            if($request->channel_name == "private-user.".$user->id){
                return $next($request);
            }else{
                return response()->json(["message" => "Unauthenticated."], 401);
            }
        }

        return response()->json(["message" => "Unauthenticated."], 401);
    }
}

广播服务提供商

Broadcast::routes(["prefix" => "api", 'middleware' => ['auth:api', 'SocketAuth']]);

注册中间件

Projectdir\app\Http Kernel.php

protected $routeMiddleware = [
    ...
    'SocketAuth' => \App\Http\Middleware\SocketAuth::class,
];

Laravel Echo服务器配置

"authEndpoint": "/api/broadcasting/auth",

后果

>

认证200-（Laravel-Echo-Server True）在：[令牌存在于来自客户端的请求和请求的用户通道==请求用户的通道]

您可以将用于验证用户的逻辑应用于中间件中的通道。
