Php 如何修复Laravel Swiftmailer中耗尽的允许内存大小？

你好，我有这个问题。 我将我的Laravelproject从5.4更新到5.7。 之后我再也不能发邮件了。我确保我有正确的Swiftmailer软件包和所有版本。 经过一些研究，我发现我的应用程序在函数addContent（）的Mailer.php上崩溃了

我的php错误日志显示以下错误消息：

"PHP Fatal error:  Allowed memory size of 536870912 bytes exhausted (tried to allocate 32768 bytes) in C:\\webroot\\projectname\\vendor\\symfony\\debug\\Exception\\FatalErrorException.php on line 1, referer: http://localhost/intranet/projectname/other-applications/create"

任何人都有一些我如何解决问题的建议吗？

经过进一步的研究，我发现它似乎在我构建消息的控制器中崩溃了

这是我的控制器：

<?php

namespace App\Mail;

use App\Models\Application;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class ApplicationCreated extends Mailable
{
    use Queueable, SerializesModels;

    public $isForSecretary;
    public $isForHeadPhysician;
    public $isForManagement;

    public $application;
    public $customMsg;

    /**
     * ApplicationCreated constructor.
     * @param Application $application
     * @param $isForSecretary
     * @param $isForHeadPhysician
     * @param null $customMsg
     */
    public function __construct(Application $application, $isForSecretary, $isForHeadPhysician, $customMsg = null)
    {
        $this->application = $application;
        $this->isForSecretary = $isForSecretary;
        $this->isForHeadPhysician = $isForHeadPhysician;
        $this->customMsg = $customMsg;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {

        $applicant = $this->application->applicant;

        return $this->view('application.responses.emails.application_created')
            ->subject('Reiseantrag: ' . $applicant->title . ' ' . $applicant->lastname)
            ->withApplication($this->application)
            ->withMail($this)
            ->with('customMsg', $this->customMsg);
    }
}

首先要弄清楚问题究竟是出在Swift-Mailer上，还是出在您试图呈现的模板上-如果您只是
$foo=$this->renderView（$view，$data）在那个地方，它仍然崩溃吗？@Cbroe如果我尝试这个方法，它仍然崩溃
if（isset（$view））{$foo=$this->renderView（$view，$data）；echo“HEre”；dd（$view）；}
<?php
