我正在尝试将Web Socket集成到我的Laravel项目中。 我已经完成了这里的所有步骤。
composer require pusher/pusher-php-server
/Users/alpha/Sites/jdoe/config/broadcasting.php
https://dashboard.pusher.com/apps/888
app_id = "888"
key = "***"
secret = "333"
cluster = "us2"
|
V
BROADCAST_DRIVER=pusher
PUSHER_APP_ID=888
PUSHER_APP_KEY=***
PUSHER_APP_SECRET=333
PUSHER_APP_CLUSTER=us2
.env.example + .env
npm install --save laravel-echo pusher-js
npm run watch
---------------------------------------------------
php artisan make:event logEvent
<?php
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;
class logEvent implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
private $data;
/**
* Create a new event instance.
*
* @return void
*/
public function __construct($data)
{
$this->data = $data;
}
/**
* Get the channels the event should broadcast on.
*
* @return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new Channel('logEventChannel');
}
public function broadcastWith()
{
return [
'data' => $this->data
];
}
}
---------------------------------------------------
/Users/alpha/Sites/jdoe/resources/js/app.js
require('./bootstrap');
Echo.channel('logEventChannel').listen('logEvent', (e) => {
// console.log(typeof JSON.parse(JSON.stringify(e))) //object
// console.log(typeof JSON.parse(JSON.stringify(e.data))) //string
// console.log(JSON.parse(e.data)); //decode or parse it
let data = JSON.parse(e.data);
/*=============================

console.log('data ===== ',data);
});
---------------------------------------------------
route
Route::post('ws/log', 'BroadcastController@logEvent');
---------------------------------------------------
Controller
<?php
namespace App\Http\Controllers;
use App\Events\LogEvent;
use Illuminate\Http\Request;
class BroadcastController extends Controller
{
public function vnfevent(Request $request)
{
$body = json_decode($request->getContent(),true);
dd($body);
$json = json_encode($body);
broadcast(new LogEvent($json));
return response()->json($body,200);
}
}

CSRF
/Users/alpha/Sites/jdoe/app/Http/Middleware/VerifyCsrfToken.php
protected $except = [
'/ws/log'
];
---------------------------------------------------
TEST
POSTman
ws/log
{
"type": "poop"
}
place a dd in broadbast
arrived !!
array:1 [
"type" => "poop"
]
ErrorException: array_merge(): Expected parameter 2 to be an array, null given in file
---------------------------------------------------
Debug the crashing line
/Users/alpha/Sites/jdoe/vendor/pusher/pusher-php-server/src/Pusher.php
dd($post_params, $params);
$all_params = array_merge($post_params, $params);
array:3 [▼
"name" => "App\Events\logEvent"
"data" => array:1 [▼
"data" => "{"type":"poop"}"
]
"channels" => array:1 [▼
0 => "logEventChannel"
]
]
Look correct
我测试了向我的/ws/log发送帖子
{
"type": "poop"
}
我一直收到以下错误信息：
ErrorException: array_merge(): 预期参数 2 是数组，但给定的是 null，文件路径为 /Users/alpha/Sites/jdoe/vendor/pusher/pusher-php-server/src/Pusher.php，行数为 518
于是我打开了那个文件。
$all_params = array_merge($post_params, $params);
$params某种方式等于null
我该如何进一步调试这个问题？
编辑
我按照建议删除了我的vendor/目录，并尝试使用版本4.1。
"require": {
"php": "^7.2.5",
"doctrine/dbal": "^2.10",
"fideloper/proxy": "^4.2",
"fruitcake/laravel-cors": "^1.0",
"guzzlehttp/guzzle": "^6.3",
"intervention/image": "^2.3",
"laravel/framework": "^7.0",
"laravel/tinker": "^2.0",
"laravelcollective/html": "~6.0",
"pusher/pusher-php-server":"^4.1"
},
我在使用POSTman向我的路由发送POST请求时仍然遇到问题。
