Laravel结合Redis发送邮箱验证码 - 糊涂

我们在某些业务上，需要注册邮箱，为避免邮箱注册混乱、乱用他人邮箱，这就需要对邮箱进行验证。
### 一、设计思路
1、用户输入邮箱，点击验证      
2、后端接收到邮箱后，随机生成一个code，用邮箱作为key，code为值保存到redis中，并使用laravel封闭的Mail类发送给用户      
3、用户收到邮件后，获取验证码并输入，后端把email、code和redis保存的值做一个匹对      
### 二、前期准备
1、修改.env配置文件里面email部分的内容

MAIL_MAILER=smtp
MAIL_HOST=smtp.qq.com
MAIL_PORT=465
MAIL_USERNAME=xxxx@qq.com
MAIL_PASSWORD=xxxxxxxxxxxxxxxxx
MAIL_ENCRYPTION=ssl
MAIL_FROM_ADDRESS=xxxx@qq.com
MAIL_FROM_NAME=糊涂

2、使用命令创建`EmailVerifyController.php`控制器
```
php artisan make:controller Index/EmailVerifyController
```
3、在routes/web.php中注册相关路由
```php
<?php

use Illuminate\Support\Facades\Route;

Route::get("sendEmailCode", "Index\EmailVerifyController@sendEmailCode");
Route::get("verify", "Index\EmailVerifyController@verify");
```
4、在resoures/views/mail创建`SendEmailCode.blade.php`模块文件
### 三、实现代码
1、EmailVerifyController.php控制器
```php
<?php

namespace App\Http\Controllers\Index;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Mail\Message;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Redis;

class EmailVerifyController extends Controller
{
    /**
     * 发送邮箱验证码
     * @param Request $request
     * @return array
     */
    public function sendEmailCode(Request $request)
    {
        $email = $request->input("email");
        $code = rand(100000, 999999);//验证码
        $expireTime = 60 * 3;//过期时间
        $EMAIL_VERIFY_CODE = "email:verify:code:" . $email;//redis key
        Redis::setex($EMAIL_VERIFY_CODE, $expireTime, $code);
        Mail::send("mail.SendEmailCode", ["code" => $code, "email" => $email], function (Message $message) use ($email) {
            $message->to($email);
            $message->subject("糊涂个人博客——邮箱验证");
        });
        if (Mail::failures()) {
            return ["code" => 0, "msg" => "warning"];
        }
        return ["code" => 1, "msg" => "success"];
    }

/**
     * 验证
     * @param Request $request
     * @return array
     */
    public function verify(Request $request)
    {
        $email = $request->input("email");
        $code = $request->input("code");
        $EMAIL_VERIFY_CODE = "email:verify:code:" . $email;//redis key
        $isCode = Redis::get($EMAIL_VERIFY_CODE);
        if ($isCode && $isCode === $code) {
            return ["code" => 1, "msg" => "success"];
        }
        return ["code" => 0, "msg" => "warning"];
    }
}

```
2、SendEmailCode.blade.php模块
```html
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        #app {
            line-height: 150%;
        }
    </style>
</head>

<body>
<div id="app">
    <div>亲爱的用户：</div>
    <br/>
    <div>您好！</div>
    <br/>
    <div>感谢您使用糊涂个人博客开发平台。您正在进行邮箱验证，请在验证码输入框中输入此次验证码<span style="color: red">{$code}</span>（3分钟内有效）以完成验证。</div>
    <div>如非本人操作，请忽略此邮件，由此给您带来的不便请谅解！</div>
    <br/>
    <div>糊涂个人博客开发平台</div>
</div>
</body>

</html>

```
### 四、实现效果
自己可以根据相关需要修改样式代码
