laravel 5.5 登录验证码 captcha 引入

安装 Captcha+

$ composer require mews/captcha

配置

/config/app.php
'providers' => [
    // ...
    Mews\Captcha\CaptchaServiceProvider::class,
]
'aliases' => [
    // ...
    'Captcha' => Mews\Captcha\Facades\Captcha::class,
]

自定义配置
$ php artisan vendor:publish

运行之后，就可以在 config/captcha.php 中进行配置了。这里使用默认配置。

/resources/views/auth/login.blade.php
<div class="form-group">
  <label for="captcha" class="col-md-4 control-label">验证码</label>
      <div class="form-group">
          <div class="col-md-3">
              <input id="captcha"  class="form-control" type="captcha" name="captcha" value="{
    { old('captcha')  }}" required>
              @if($errors->has('captcha'))
                  <div class="col-md-12">
                      <p class="text-danger text-left"><strong>{
    {$errors->first('captcha')}}</strong></p>
                  </div>
              @endif
          </div>
          <div class="col-md-4">
              <img src="{
    {captcha_src()}}" style="cursor: pointer" οnclick="this.src='{
    {captcha_src()}}'+Math.random()">
          </div>
      </div>
  </div>

首先要引入如下代码：
use Illuminate\Http\Request;

重写validateLogin方法：

在验证里面加入验证码的规则验证即可
/**
 * DESC: 重写 AuthenticatesUsers 登录验证方法，并自定义提示信息;
 * 原验证方法 Illuminate\Foundation\Auth\AuthenticatesUsers
 * @param Request $request
 */
protected function validateLogin(Request $request){
    $this->validate($request, [
        $this->username() => 'required|string',
        'password' => 'required|string',
        'captcha' => 'required|captcha',
    ],[
        'captcha.required' => '请填写验证码',
        'captcha.captcha' => '验证码错误',
    ]);
}
