###### 验证图片验证码

[](#验证图片验证码)

```
CaptchaApi::check($code,$key);

其中code为用户输入的验证码， key为上面返回到key 用于替代session， 同时使用cache作为缓冲

```

基于think-captcha进行扩展，保留了think-captcha所有功能，用于非前后端分离项目

### 在控制器中输出验证码

[](#在控制器中输出验证码)

在控制器的操作方法中使用

```
public function captcha($id = '')
{
	return captcha($id);
}

```

然后注册对应的路由来输出验证码

### 模板里输出验证码

[](#模板里输出验证码)

首先要在你应用的路由定义文件中，注册一个验证码路由规则。

```
\think\facade\Route::get('captcha/[:id]', "\\think\\captcha\\CaptchaController@index");

```

然后就可以在模板文件中使用

```
{:captcha_img()}

```

或者

```

```

> 上面两种的最终效果是一样的

### 控制器里验证

[](#控制器里验证)

使用TP的内置验证功能即可

```
$this->validate($data,[
    'captcha|验证码'=>'require|captcha'
]);

```

或者手动验证

```
if(!captcha_check($captcha)){
 //验证失败
};

```
