问题描述
我需要帮助以使用 Laravel 调度作业，似乎系统在使用队列作业时尝试序列化闭包，因此出现此错误.
I need help to dispatch a job with Laravel, seems the system try to serialize a closure when using queue job so there's this error.
我该如何解决这个问题?我也试过这个包
https://github.com/jeremeamia/super_closure
但在我的情况下它不起作用.
How can I fix this problem? I also tried this package
https://github.com/jeremeamia/super_closure
but it doesn't work in my case.
这是我的代码:
在控制器 FacebookController 中:
In the controller FacebookController:
public function getPosts(SammyKLaravelFacebookSdkLaravelFacebookSdk $fb) //get all post of logged user
{
dispatch(new SyncFacebook($fb));
}
还有要派遣的工作:
<?php
namespace AppJobs;
use IlluminateBusQueueable;
use IlluminateQueueSerializesModels;
use IlluminateQueueInteractsWithQueue;
use IlluminateContractsQueueShouldQueue;
use IlluminateFoundationBusDispatchable;
use Session, DB, CarbonCarbon, Auth;
use App{
User, Reaction, Post, Synchronisation
};
class SyncFacebook implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $fb;
public function __construct($fb)
{
$this->fb = $fb;
}
public function handle()
{
set_time_limit(0);
$user = Auth::user();
try {
$response = $this->fb->get('/me/posts?limit=100', session('fb_user_access_token'));
} catch(FacebookExceptionsFacebookSDKException $e) {
dd($e->getMessage());
}
$postEdge = $response->getGraphEdge();
if(count($postEdge) > 0){
$pageCount = 0;
$maxPages = 9000000000000000000;
DB::beginTransaction();
try{
do{
foreach ($postEdge as $result) {
$result = $result->asArray();
$post_id = $result['id'];
$post = Post::where('post_id', $post_id)->first() ?: new Post;
$post->post_id = $post_id;
$post->user_id = $user->id;
$post->timezone = collect($result['created_time'])->toArray()['timezone'];
$post->post_date = collect($result['created_time'])->toArray()['date'];
$post->content = $result['message'] ?? $result['story'] ?? '';
$post->save();

$post_id.'/reactions?limit=100&summary=total_count&since'.time(Synchronisation::whereUserId($user->id)->orderBy('id','desc')->date) :
$post_id.'/reactions?limit=100&summary=total_count';
try {
$response = $this->fb->get($req, session('fb_user_access_token'));
} catch(FacebookExceptionsFacebookSDKException $e) {

$react = $react->asArray();
$reaction = Reaction::where('reaction_id', $react['id'])->first() ?: new Reaction;
$reaction->type = $react['type'];
$reaction->reaction_id = $react['id'];
$reaction->post_id = $post->id;
$reaction->author = $react['name'];
$reaction->save();
}
$pagesReactionCount++;
}
while($pagesReactionCount < $maxPages && $reactionEdge = $this->fb->next($reactionEdge));
}
}
$pageCount++;
}
while ($pageCount < $maxPages && $postEdge = $this->fb->next($postEdge));
$synchro = new Synchronisation;
$synchro->user_id = $user->id;
$synchro->date = now();
$synchro->completed = true;
$synchro->save();
}
catch(ValidationException $e){
DB::rollback();
if(env('APP_ENV') != 'production'){
dd($e->getMessage());
}
}
DB::commit();
}
else{
//no post
}
}
}
似乎错误出现在 $this->fb = $fb;//'Closure' 的序列化的构造函数上
It seems the error is on the constructor at $this->fb = $fb; // Serialization of 'Closure' is not allowed
推荐答案
我的理解是不能在 Job 中包含不可序列化的变量，因为 Laravel 在存储 Job 详细信息时不知道如何处理它们.
My understanding is that you can't include non-serializable variables in the Job, as Laravel won't know how to deal with them when storing the job details.
所以你需要从 construct() 方法和关联的 protected $fb; 和 $ 中删除 行.$fbthis->fb = $fb;
So you need to remove the $fb from the construct() method and the associated protected $fb; and $this->fb = $fb; lines.
相反，您有两个选择
1) 简单
在您的 handle() 方法中创建一个新的 SammyKLaravelFacebookSdkLaravelFacebookSdk 对象，例如
Create a new SammyKLaravelFacebookSdkLaravelFacebookSdk object in your handle() method, e.g.
public function handle() {
$fb = new SammyKLaravelFacebookSdkLaravelFacebookSdk;
'.... replace all $this->fb with $fb
}
2) 高级
如果需要传递之前使用的具体FB实例，注册一个FacebookSDK Service Provider 和 将其注入处理程序，如文档.
If you need to pass the specific FB instance you used before, register a FacebookSDK Service Provider and inject it into the handler as seen in the docs.
例如
public function handle(FacebookSDK $fb) {
'.... replace all $this->fb with $fb
}
当您为 Facebook SDK 注册绑定服务容器时，handle() 方法中的这种类型提示会自动检索 $fb 实例并将其注入到可供使用的方法中.您可以确定是每次都创建一个新的 FacebookSDK 对象，还是只创建一个并始终使用该对象(称为 Singleton).
When you register bind the service container for your Facebook SDK, this type-hinting in the handle() method automatically retrieves the $fb instance and injects it into the method ready for use. You can determine whether to create a new FacebookSDK object each time, or just create one and always use that one (known as a Singleton).
