在 Laravel 中使用准备好的模板发送电子邮件时遇到麻烦：

问：

我遇到了错误和问题，尤其是在处理异常和转义 HTML 字符时。我将不胜感激任何有关使用 laravel 10 发送带有模板的电子邮件的最佳实践的指导，以及解决我面临的问题的任何见解。先谢谢你！

在邮件中，只有html代码是可见的，预期是html页面。

我正在使用 [][1]https://app.bootstrapemail.com/templates/free-simple-card

 public function prepareTemplate($subject, $body, $templateId)
    {
        $subject = htmlentities($subject, ENT_QUOTES, 'UTF-8');
        $body = htmlentities($body, ENT_QUOTES, 'UTF-8');
        // Load the template from your database or source
        $template = $this->templates::where('InternalID', $templateId)->first(); // Assuming you want to retrieve a single template.

        $templateHeader = $template->Header;
        $templateFooter = $template->Footer;

    // Replace placeholders in the template body with dynamic content
        $templateBody = str_replace('{{ subject }}', $subject, $template->Body);
        $templateBody = str_replace('{{ body }}', $body, $templateBody);

        // Escape HTML characters in subject and body


        // Combine the header, dynamic body, and footer
        $completeTemplate = $templateHeader . $templateBody . $templateFooter;

        return $completeTemplate;

    } 

 // SendMail

  



 public function SendMail($notification)
    {
    
        // Inject the Templates model when creating TemplateService
        $templateService = new TemplateService(new Templates);
        $template  =  $templateService->prepareTemplate($notification->Subject,$notification->Body,1);
    
        try {
            Mail::to($notification->Contact)->send(new MyTestEmail($notification,$template));
        } catch (\Exception $e) {
            $this->updateNotificationService->UpdateTriedCount($notification);
            Log::info(['Failed Notification '=>$notification]);
           return false;
        }
    }
