基于 php-captcha 的验证码插件。对 PSR7 适配。增加 Base64 输出和字节输出。

## 安装

$ composer require pluveto/swoole-captcha dev-master

```

## 使用

```php

/**

 * @api {get} /auth/captcha 获取验证码

 * @apiName GetCaptcha

 * @apiGroup auth

 * @apiVersion  1.0.0

 * @apiPermission none

 * 

 * @apiParam  {number{32-320}} [width=180] 宽度 

 * @apiParam  {number{32-320}} [height=64] 高度 

 * @apiParam  {boolean} [raw=true]

 * @apiParam  {string} [uuid=""] UUID

 */

public function getCaptcha()

{    

    $req = $this->params();

    if (!$req->uuid) {

        $uuid = uuid();

    } else {

        $uuid = $this->authValidation->validateUUID($req->uuid);

    }

    $captha = new CaptchaBuilder();

    $captha->initialize([

        'width' => $req->width,     // 宽度

        'height' => $req->height,   // 高度

        'line' => false,            // 直线

        'curve' => true,            // 曲线

        'noise' => 1,               // 噪点背景

        'fonts' => []               // 字体

    ]);

    $captha->create();

    $text = $captha->getText(); // 获取验证码文本

    // 将验证码放到缓存中

    $redis = ApplicationContext::getContainer()->get(\Hyperf\Redis\Redis::class);

    $redis->set('captcha_' . str_replace("-", "", $uuid), $text, 60);

    

    if ($req->raw) {

        // 直接输出验证码

        return $captha->output($this->response->raw(""), 1);

    } else {

        // 通过 base64 输出验证码

        return $this->success(

            [

                "uuid" => $uuid,

                "expiredAt" => time() + 60,

                "content" => $captha->getBase64(1)

            ]

        );
