我在codeigniter中有一个站点,该站点在http上完美运行.
我的客户将网站移至https.
然后现在当用户注册不起作用时,因为它中有一个recaptcha.
这是我控制器中的recaptcha调用：
$privatekey = "my-key";
$resp = recaptcha_check_answer ($privatekey,$_SERVER["REMOTE_ADDR"],$_POST["recaptcha_challenge_field"],$_POST["recaptcha_response_field"]);
if (!$resp->is_valid) {
// What happens when the CAPTCHA was entered incorrectly
die ("The reCAPTCHA wasn't entered correctly");
}else{
$data=$this->authmodel->addAccount();
$this->session->set_flashdata('abc','User added successfully');
echo "1";
}

那么我该如何解决这个问题呢？
