简介
--

[](#简介)

一个简单的laravel5图形验证码扩展包（zxj95121已fork并做验证码存储到redis的修改，因为Session不支持前后端分离）

环境要求
----

[](#环境要求)

1. PHP >= 5.5
2. php-gd
3. [illuminate\\support](https://github.com/illuminate/support) ^5.1
4. [symfony/http-foundation](https://github.com/symfony/http-foundation) >= 2.0

安装
--

[](#安装)

### 使用composer安装扩展包

[](#使用composer安装扩展包)

先通过`composer`安装扩展包到项目中

```
composer require vicens/captcha
```

### 注册服务提供者和别名(Laravel5.5无需手动注册)

[](#注册服务提供者和别名laravel55无需手动注册)

在`config/app.php` 配置文件的`providers`数组中，注册服务提供者：

```
'providers' => [
    // Other service providers...
    \Vicens\Captcha\Providers\CaptchaServiceProvider::class
]
```

如果你使用`Captcha`别名的话，在`aliases`数组中注册别名：

```
'aliases' => [
    // Other facades...
    'Captcha' => \Vicens\Captcha\Facades\Captcha::class
]
```

配置
--

[](#配置)

如果你想使用自己的配置,你可以执行以下命令发布配置文件`config/captcha.php`：

```
php artisan vendor:publish --provider=\Vicens\Captcha\Providers\CaptchaServiceProvider
```

```
return array(
    /**
     * 调试模式(不验证验证码的正确性), 设置为null时, 取值为app.debug
     *
     * @var bool|null
     */

    'distortion' => true,
    /**
     * 最大前景线条数
     *
     * @var int
     */
    'maxFrontLines' => null,
    /**
     * 最大背景线条数
     *
     * @val int
     */
    'maxBehindLines' => null,
    /**
     * 文字最大角度

     */
    'maxAngle' => 8,
    /**

```

返回图片二进制内容：

```

```

#### 验证和测试

[](#验证和测试)

仅测试验证码的正确性：
