上面是类

调用

public function actionRsa() { $rsa = new \app\services\Rsa(); $data['mobile'] = '18146721110'; $data['password'] = '123456'; $privEncrypt = $rsa->privEncrypt(json_encode($data)); echo '私钥加密后:' . $privEncrypt . '
'; $publicDecrypt = $rsa->publicDecrypt($privEncrypt); echo '公钥解密后:' . $publicDecrypt . '
'; $publicEncrypt = $rsa->publicEncrypt(json_encode($data)); echo '公钥加密后:' . $publicEncrypt . '
'; $privDecrypt = $rsa->privDecrypt($publicEncrypt); echo '私钥解密后:' . $privDecrypt . '
'; echo '私钥解密后:' . $privDecrypt . '
'; }

生成公私秘钥方法不写了,生成个测试的到这里​​时间有效期校验

例子

if ($key != null){ $rsa = new \app\services\Rsa(); $publicDecrypt = $rsa->publicDecrypt($key); $publicDecrypt = json_decode($publicDecrypt,true); $mobile = isset($publicDecrypt['mobile']) ? $publicDecrypt['mobile'] : ""; $password = isset($publicDecrypt['password']) ? $publicDecrypt['password'] : ""; }else{ return $this->returnData('', -1, '手机号和密码必传'); } if ( $time != null) { $last_time = $time+20; if($last_time < $x_time){ return $this->returnData('', -1, '请求超时'); } } else { return $this->returnData('', -1, '请求异常'); }
