laravel-echo，加入私人频道报错419，解决。

@lmdfx 你用的那个包全名叫什么？有github地址吗？如果是 这个 下面有说明：

// Setup options
EchoOptions options = new EchoOptions();

// Setup host of your Laravel Echo Server
options.host = "http://{my-host}:{my-port}";
/*
 * Add headers for authorizing your users (private and presence channels).
 * This line can change matching how you have configured 
 * your guards on your Laravel application
 */
options.headers.put("Authorization", "Bearer {token}");
...
SocketIOPrivateChannel privateChannel = echo.privateChannel("channel-name");
privateChannel.listen("EventName", new EchoCallback() {
    @Override
    public void call(Object... args) {
        // Event thrown.
    }
});

@LiamHao 是这个包，但是加了token之后，加入频道还是会419，，
这是安卓端代码，

这是服务器laravel-echo-server报的错

@lmdfx config/auth.php 和 routes.channels.php 里面是怎么写的？用的是 socket.io + laravel-echo-server 作为 socket 通信的客户端和服务端吗？

@LiamHao

'defaults' => [
        'guard'     => 'web',
        'passwords' => 'users',
    ],

    /*
    |--------------------------------------------------------------------------
    | Authentication Guards
    |--------------------------------------------------------------------------
    |
    | Next, you may define every authentication guard for your application.
    | Of course, a great default configuration has been defined for you
    | here which uses session storage and the Eloquent user provider.
    |
    | All authentication drivers have a user provider. This defines how the

    | mechanisms used by this application to persist your user's data.
    |
    | Supported: "session", "token"
    |
    */

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

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

这是config/auth.php

Broadcast::channel('{target}.chat', ChatChannel::class);

这是channels.php

class ChatChannel
{
    /**
     * Create a new channel instance.
     *
     * @return void
     */
    public function __construct()
    {

    }

    /**
     * Authenticate the user's access to the channel.
     *
     * @param  \Zhiyi\Plus\Models\User  $user
     * @param  User  $target
     * @return array|bool
     */
    public function join(User $user, User $target)
    {
        Log::info('room', ['chat.user' => $target->id.'--'. $user->id]);

        return $user->id === $target->id;
    }
}

这是channels.php引入的ChatChannel类
然后，服务端用的是laravel-echo-server和sockit.io

@lmdfx 你 app 需要登陆到服务器就可以，默认是用 session 做验证的，也就是 app 要有对应的 session 。如果你没法做到 app 保持登陆状态，那就需要将{target}.chat这个频道改为其他的认证方式，例如 token 认证。将：

Broadcast::channel('{target}.chat', ChatChannel::class);

改为

Broadcast::channel('{target}.chat', ChatChannel::class, ['guards' => 'api']);

就可以了。但这样会使 web 端的验证也被迫变为 token 认证方式，如果你想保持 web 端依然使用 session 驱动进行认证，而 app 使用 token 认证，可以这样写：

Broadcast::channel('{target}.chat', ChatChannel::class, ['guards' => ['web','api']]);

@LiamHao 嗯嗯，我突然发现，laravel的版本是5.7，好像不支持

Broadcast::channel('{target}.chat', ChatChannel::class, ['guards' => ['web','api']]) 

这种写法呀，它只能传两个参数

@LiamHao
可以这样写,在app/Providers/BroadcastServiceProvider.php，这里认证。

class BroadcastServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Broadcast::routes(['middleware' => ['web','auth:api']]);

        require base_path('routes/channels.php');
    }
}

谢谢大佬

@lmdfx 哈，对，我给忘了，尴尬。之前 臭鼬 这个大佬在我的文章下留言了，链接在这：博客：「手把手」通过laravel-echo主动向服务端发送消息，实现在线状态管理
