具體問(wèn)題：

Laravel 8 使用mailable發(fā)送郵件，undefined variable錯(cuò)誤？

Laravel 8 使用 mailable 的方法發(fā)送郵件，一直出現(xiàn) undefined variable 的錯(cuò)誤，但是參照網(wǎng)上的解決方案，使用 public 定義 variable，但是還是報(bào)同樣的錯(cuò)誤

  public $jobdocumentmessage;     /**      * Create a new message instance.      *      * @return void      */     public function __construct($jobdocumentmessage)     {         $this->jobdocumentmessage = $jobdocumentmessage;     }     /**      * Build the message.      *      * @return $this      */     public function build()     {         #dd($jobdocumentmessage);         return $this->view('emails.jobDocument')                     ->with([                         'body' => $jobdocumentmessage->body,                         'user' => $jobdocumentmessage->user,                         ])                     ->subject($jobdocumentmessage->subject)                     ->replyTo($jobdocumentmessage->mail)                     ->attach($jobdocumentmessage->url, ['as' => $jobdocumentmessage->name                 ]);     }

解決辦法：

  public $jobdocumentmessage;      /**      * Create a new message instance.      *      * @return void      */     public function __construct($jobdocumentmessage)     {         $this->jobdocumentmessage = $jobdocumentmessage;     }      /**      * Build the message.      *      * @return $this      */     public function build()     {         $jobdocumentmessage= $this->jobdocumentmessage ;         return $this->view('emails.jobDocument')                     ->with([                         'body' => $jobdocumentmessage->body,                         'user' => $jobdocumentmessage->user,                         ])                     ->subject($jobdocumentmessage->subject)                     ->replyTo($jobdocumentmessage->mail)                     ->attach($jobdocumentmessage->url, ['as' => $jobdocumentmessage->name                 ]);     }
