**前期準備**
1.在項目的根目錄下通過composer來安裝phpmail發送郵件的擴展包
```
composer require phpmailer/phpmailer
```
2.由于前后臺都需要發送郵件，因此需要定一個公共函數
app\common.php
```
//////使用的是163郵箱
<?php
/**
* 公共函數
*/
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
function mailto($user,$subject,$content){
$mail = new PHPMailer(true);
try {
//Server settings
$mail->SMTPDebug = 0; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->CharSet='utf-8';
$mail->Host = 'smtp.163.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'example@163.com'; // SMTP username
$mail->Password = 'password'; // SMTP 授權碼（不是登錄密碼）
$mail->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465; // TCP port to connect to
//Recipients
$mail->setFrom('example@163.com', '名稱');
$mail->addAddress($user); // Add a recipient
// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = $subject;
$mail->Body = $content;
return $mail->send();
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
}
```
## 1.路由
routes/web.php
```php
Route::namespace('Admin')->group(function () {
Route::match(['GET', 'POST'], '/forget', 'Index@forget');
});
```
## 2.忘記密碼頁面
admin/index/forget.balde.php
```html

## 3.控制器
Controller/admin/Index.php(reister操作方法)
```php
// 忘記密碼
public function forget()
{
if (request()->isMethod('post')){
$data=request()->only(['email']);
$res=(new Admin)->getCode($data);
if ($res == 1){
$msg=[
'code'=>1,
'msg'=>'驗證碼發送成功'
];
}else{
$msg=[
'code'=>1,
'msg'=>$res
];
}
return $msg;
}
return view('admin.index.forget');
}
```
## 4.模型
Models\Admin.php
```php
public function getCode($data)
{
$rules=[
'email'=>'bail|required|email',
];
$msg=[
'email.required'=>'郵箱不能為空',
'email.email'=>'請填寫正常郵箱格式',
];
$validate=Validator::make($data,$rules,$msg);
if ($validate->fails()){
return $validate->errors()->first();
}
$res=$this->where('email',$data['email'])->first();
if ($res){
$code=mt_rand(1000,9999);
session(['code'=>$code]);
$content='您的驗證碼是'.$code;
$sendMail=mailto($data['email'],'獲取驗證碼,$content);
if ($sendMail){
return 1;
}else{
return '發送失敗，請等待一會再試~~';
}
}else{
return '該郵箱尚未注冊';
}
}
```
