Question

thinkphp后台登陆ajax提交验证码怎么进行判断

Answer 1

1. 判断传过去的验证码和cookie里的验证码让否一致

   具体代码如下：

   
   
   

 protected function
check_verify($code) //验证函数
{
$verify = new
\Think\Verify();
return $verify->check($code);
}
Public function login(){ //登陆
$authcode = trim(I('authcode'));
//获取前端ajax传过来的authcode

if ( (
!$this->check_verify($authcode)) ){
$this->ajaxReturn(0,"验证码错误",0);

}

Answer 2

protected function check_verify($code) //验证函数，3.2.3版本
{
$verify = new \Think\Verify();
return $verify->check($code);
}
Public function dologin(){ //登陆
$authcode = trim(I('authcode')); //获取前端ajax传过来的authcode
//下面的代码是3.2.3验证
if ( ( !$this->check_verify($authcode)) ){
$this->ajaxReturn(0,"验证码错误",0);
}

Answer 3

就是判断传过去的验证码和cookie里的验证码让否一致
