Laravel验证码安装

github地址：https://github.com/mewebstudio/captcha

1. composer安装

# composer require mews/captcha

2. 在config/app.php的providers中注册Captcha

对于Laravel 5.1+

    ' providers '  => [
    Mews\Captcha\CaptchaServiceProvider::class,
   ]

3. 再在config/app.php的aliases中添加

对于Laravel 5.1+

    ' aliases '  => [
    'Captcha' => Mews\Captcha\Facades\Captcha::class,  
  ]

4. 配置

要使用自己的设置，发布配置。

$ php artisan vendor:publish

会生成 config/captcha.php

return [
    'default'   => [
        'length'    => 5,
        'width'     => 120,
        'height'    => 36,
        'quality'   => 90,
    ],
    // ...
];

5. 示例用法

// [your site path]/Http/routes.php
首先引入类：use Validator;

    Route::any('captcha-test', function()
    {
            $rules = ['captcha' => 'required|captcha'];
            $messages = [
                'captcha.required' => '验证码为必填项',
                'captcha.captcha' => '验证码错误',
            ];
            $validator = Validator::make(Input::all(), $rules,$messages);
            if ($validator->fails()){
                 return back()->withErrors($validator);
            }
   }

6. 点击验证码切换 js事件

（*要在index.php开头添加session_start(); 不然无法切换）

@if ($errors->has('captcha'))
    <div class="alert alert-danger">
        {{$errors->first('captcha')}}
    </div>
@endif

 <input class="input-text size-L" name="captcha" type="text" placeholder="验证码"   style="width:150px;">
<img src="{{captcha_src()}}" onclick="this.src='{{captcha_src()}}?+Math.random()'"  style='cursor:pointer;' title="看不清?点击换一张">
