使用队列时不允许序列化“关闭" [英] Serialization of 'Closure' is not allowed when using queues

问题描述

这是我的RequestMail.php文件:

Here's my RequestMail.php file:

protected $phone;

/**
 * Create a new message instance.
 *
 * @return void
 */
public function __construct(Request $request)
{
    $this->request = $request;
    $this->phone = $request->get('phone');
}

/**
 * Build the message.
 *
 * @return $this
 */
public function build()
{
    return $this->from('[e-mail]')
                ->view('request')
                ->subject('Новая заявка на обмен криптовалют')
                ->with(['phone' => $this->phone]);
}

我的控制器:

Mail::to('[e-mail]')->queue(new RequestMail($request));

当我尝试将邮件排队时，出现以下错误:不允许对关闭"进行序列化"

When i am trying to queue the mail, i am getting the following error: "Serialization of 'Closure' is not allowed"

EDIT 更新了最终代码.

推荐答案

如果使用队列，则无法序列化包含闭包的对象，这就是PHP的工作方式.每次将作业推送到队列时，Laravel会将其属性序列化为可以写入数据库的字符串，但是匿名函数(例如，不属于任何类的函数)不能表示为字符串值，因此它们不能被序列化.因此，基本上，当您将RequestMail作业推入队列时，Laravel尝试序列化其属性，但是$request是一个包含闭包的对象，因此无法序列化.要解决此问题，您只必须在可序列化的属性中存储RequestMail类:

If you are using queues you cannot serialize Objects that contains closures, it's the way PHP works. Every time you push a job onto a queue, Laravel serializes its properties to a string that can be written to the database, but anonymous functions (e.g. functions that do not belong to any class) cannot be represented as a string value, thus they cannot be serialized. So basically when you push your RequestMail job onto the queue, Laravel tries to serialize its properties, but $request is an object that contains closures, so it cannot be serialized. To solve the problem you have to store in the RequestMail class only properties that are serializable:

protected $phone;

/**
 * Create a new message instance.
 *
 * @return void
 */
public function __construct(Request $request)
{
    $this->phone = $request->get('phone');
}

public function build()
{
    return $this->from('[e-mail]')
                ->view('request')
                ->subject('New request for exchange')
                ->with(['phone' => $this->phone]);
}

这样做，您仅保留了实际需要的$request属性，在这种情况下为电话号码，它是一个字符串，可以完全序列化.

Doing such thing you are keeping only the properties of $request that you actually need, in this case the phone number, that is a string and it is perfectly serializable.

编辑 我刚刚意识到这是一个

EDIT I've realized just now that this is a duplicate

编辑2 我已经使用正确的请求参数检索来编辑代码，以供进一步参考.

EDIT 2 i've edited the code with the correct request parameter retrieval for further reference.
