easyswoole验证码组件,安装:
代码语言：javascript复制easyswoole/verifycode调用方法:
代码语言：javascript复制$config = new Conf();
$code = new EasySwooleVerifyCodeVerifyCode($config);
$code->DrawCode();//生成验证码,返回一个Result对象在easyswoole控制器中使用:
代码语言：javascript复制use EasySwooleUtilityRandom;
use EasySwooleVerifyCodeConf;
use EasySwooleVerifyCodeVerifyCode as VerifyCodeModel;
function verifyCode()
{
$ttl = 120;
$conf = new Conf();
$VCode = new VerifyCodeModel($conf);
// 随机生成验证码
$random = Random::character(4, '1234567890abcdefghijklmnopqrstuvwxyz');
$code = $VCode->DrawCode($random);
$result = [
'verifyCode' => $code->getImageBase64(),
'verifyCodeTime' => time(),
];
$this->writeJson(200, $result, 'success');
}注意,需要自己保存验证码,这样用户才能验证成功
可通过session组件,或者使用另一种验证方式进行验证:关于验证码存储机制的转变
