[](#使用)

### 直接访问获取验证码

[](#直接访问获取验证码)

你的项目域名/captcha 如：

可在think-captcha/src/CaptchaController.php中修改适合自身项目的返回值

### 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);
}

```

在控制器中可直接使用，返回验证码图片和对应的唯一键值

### 控制器里验证

[](#控制器里验证)

使用TP的内置验证功能即可（key与code需要使用'-'连接） 示例如下：

```
$data['captcha'] = input('key').'-'.input('code');
try {
    $this->validate($data,[
        'captcha|验证码'=>'require|captcha'
    ]);
} catch (ValidateException $e) {
    // 验证失败 输出错误信息
    dump($e->getError());
}

```

或者手动验证

```
if(!captcha_check($key, $code)){
 //验证失败
};

```
