二，实际操作

1,设置目录:

在项目根目录下新建目录 extend:

修改composer.json

"psr-0" : {
    "": "extend/"
}

如图:

<?php
namespace captcha;
use Webman\Captcha\CaptchaBuilder;
use Webman\Captcha\PhraseBuilder;
 
class captcha {
      static public function getCaptcha($codeLength,$width,$height) {
// 验证码长度
          //$length = 4;
          // 包含哪些字符
          $chars = '0123456789abcefghijklmnopqrstuvwxyz';
          $builder = new PhraseBuilder($codeLength, $chars);
          $captcha = new CaptchaBuilder(null, $builder);
 
          // 生成验证码
          $captcha->build($width, $height, $font = null);
          // 将验证码的值存储到session中
          //$request->session()->set('captcha', strtolower($captcha->getPhrase()));
          /*
          // base64 image
          $image = $captcha->inline();
          //json
          return json(['code' => 0, 'image'=>$image,'uniqid'=>'123']);
          */
          // 获得验证码图片二进制数据
          $img_content = $captcha->get();
          //return response($img_content, 200, ['Content-Type' => 'image/jpeg']);
          return $img_content;
      }
 
      static public function checkCaptcha() {
 
      }
}
