如何解决在 Vue 前端使用 Pusher 和 Laravel Echo 实现 Laravel 8 广播
我正在尝试使用 Laravel 实现事件广播和通知。目标是通过通知向登录用户广播私人消息。
我创建了这个事件,见下面的代码:
<?php
namespace App\Events;
use App\Models\User;
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 TradingAccountActivation implements ShouldBroadcast
{
use Dispatchable,InteractsWithSockets,SerializesModels;
/**
* The authenticated user.
*
* @var \Illuminate\Contracts\Auth\Authenticatable
*/
public $user;
public $message;
/**
* Create a new event instance.
*
* @param \Illuminate\Contracts\Auth\Authenticatable $user
* @return void
*/
public function __construct(User $user)
{
$this->user = $user;
$this->message = "{$user->first_name} is ready to trade";
}
/**
* Get the channels the event should broadcast on.
*
* @return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel('user.'.$this->user->id);
}
}
每个新验证的用户都会触发该事件,因此我将事件放在项目的电子邮件验证控制器中,请参阅以下代码:
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Auth\Events\Verified;
use App\Events\TradingAccountActivation;
use Illuminate\Foundation\Auth\EmailVerificationRequest;
class VerifyEmailController extends Controller
{
/**
* Mark the authenticated user's email address as verified.
*
* @param \Illuminate\Foundation\Auth\EmailVerificationRequest $request
* @return \Illuminate\Http\RedirectResponse
*/
public function __invoke(EmailVerificationRequest $request)
{
if ($request->user()->hasVerifiedEmail()) {
return redirect()->intended(RouteServiceProvider::HOME.'?verified=1');
}
if ($request->user()->markEmailAsVerified()) {
event(new Verified($request->user()));
}
event(new TradingAccountActivation($request->user()));
return redirect()->intended(RouteServiceProvider::HOME.'?verified=1');
}
}
此时事件失败并显示以下错误消息:
ErrorException
array_merge(): Expected parameter 2 to be an array,null given
堆栈跟踪指向带有星号的行上的 pusher:
Illuminate\Foundation\Bootstrap\HandleExceptions::handleError
C:\xampp\htdocs\spa\vendor\pusher\pusher-php-server\src\Pusher.php:391
$path = $this->settings['base_path'].'/events';
// json_encode might return false on failure
if (!$data_encoded) {
$this->log('Failed to perform json_encode on the the provided data: {error}',array(
'error' => print_r($data,true),),LogLevel::ERROR);
}
$post_params = array();
$post_params['name'] = $event;
$post_params['data'] = $data_encoded;
$post_params['channels'] = array_values($channels);
* $all_params = array_merge($post_params,$params);
$post_value = json_encode($all_params);
$query_params['body_md5'] = md5($post_value);
Laravel Telescope 确认事件失败并提供以下详细信息:
工作详情

连同事件要发出的数据:
{

"class": "App\Events\TradingAccountActivation","properties": {
"user": {
"id": 75,"uuid": "75da67ef-d6f8-4cd0-9d57-e1dcf66c1f5e","first_name": "John","last_name": "Doe","mobile_phone_number": "08033581133","verification_code": null,"phone_number_isVerified": 0,"phone_number_verified_at": null,"email": "j@doe.com","email_verified_at": "2021-04-06T08:04:49.000000Z","created_at": "2021-04-06T08:03:56.000000Z","updated_at": "2021-04-06T08:04:49.000000Z"
},"message": "John is ready to trade","socket": null
}
},"tries": null,"timeout": null,"connection": null,"queue": null,"chainConnection": null,"chainQueue": null,"chainCatchCallbacks": null,"delay": null,"afterCommit": null,"middleware": [
],"chained": [
]
}
奇怪的是,尽管事件失败,但似乎广播频道已创建并已建立连接。刷新错误页面似乎继续控制器的下一个操作,即重定向到经过身份验证的用户的仪表板。此时建立广播连接。请参阅下面的 Laravel Telescope 详细信息以及有效负载:

由于事件失败,我没想到会建立一个广播通道,或者为后续的侦听器和通知广播消息触发。
我无法弄清楚事件失败的原因,即如何处理异常“array_merge(): Expected parameter 2 to be an array,null given”,或者如何修复它。
或者是否与接收/记录/显示广播消息的后续代码有关。
谢谢。
解决方法
此问题已在 8.29.0 版本中解决。您需要升级到指定的版本,或者降级 pusher-http-php (composer require pusher/pusher-php-server ^4.1
)
