laravel 5.4 在邮件中嵌入图像 [英] laravel 5.4 embed image in mail

问题描述

我刚刚按照官方升级方法将 Laravel 的 5.2 安装升级到 5.3，然后升级到 5.4.

I have just upgraded my 5.2 install of laravel to 5.3 and then to 5.4 following the official upgrading methods.

我现在正在尝试使用其中一项新功能来创建降价格式的电子邮件.

I am now trying to use one of the new features, to create a markdown formated email.

根据在以下位置找到的文档:https://laravel.com/docs/5.4/mail#view-data

According to the documentation found at: https://laravel.com/docs/5.4/mail#view-data

要嵌入内嵌图像，请使用 $message 上的 embed 方法电子邮件模板中的变量.Laravel 自动使$message 变量可用于您的所有电子邮件模板，因此您无需担心手动传入:

To embed an inline image, use the embed method on the $message variable within your email template. Laravel automatically makes the $message variable available to all of your email templates, so you don't need to worry about passing it in manually:

然而，这:

<img src="{{ $message->embed(public_path().'/img/official_logo.png') }}">

会产生以下错误:

未定义变量:message

我错过了什么吗?或者升级指南中是否有未记录的内容?

Am I missing something? Or is there something undocumented in the upgrading guides?

后期

我正在调用电子邮件功能:

I am calling the email function with:

Mail::to($user)->send(new WelcomeCandidate($user, $request->input('password')));

WelcomeCandidate 看起来像:

And WelcomeCandidate looks like:

<?php

namespace AppMail;

use IlluminateBusQueueable;
use IlluminateMailMailable;
use IlluminateQueueSerializesModels;
use IlluminateContractsQueueShouldQueue;

use AppModelsUser;

class WelcomeCandidate extends Mailable
{

    use Queueable, SerializesModels;

    public $user;
    public $password;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct(User $user, $password)
    {
        //
        $this->user = $user;
        $this->password = $password;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        $this->subject('Welcome!');
        return $this->markdown('emails.welcome-candidate');
    }
}

推荐答案

旧的 $message->embed 似乎不适用于 Markdown 电子邮件.就像你在评论中提到的，它似乎从 5.4 开始就坏了

It seems that the older $message->embed doesn't work nicely with Markdown emails. Like you mentioned in the comments it seems broken since 5.4

但你可以在你的降价电子邮件中尝试这样:

But you could just try it like this inside your markdown email:

This is your logo 
![Some option text][logo]

[logo]: {{asset('/img/official_logo.png')}} "Logo"
