php – recaptcha总是返回false

一切都是最新的,使用最新的库并三重检查代码和公钥/私钥.

问题我相信在这里……

require_once('recaptchalib.php');
          $privatekey = "************************************";
    $resp = recaptcha_check_answer ($privatekey,$_SERVER["REMOTE_ADDR"],$_POST["recaptcha_challenge_field"],$_POST["recaptcha_response_field"]);

if (!$resp->is_valid) {
                  $error_string .= '<center>The reCAPTCHA wasnt entered correctly. Go back and try it again.</center><br />';
        }

我按照这个例子,所以我看不出有什么问题.已经好几天了！

https://developers.google.com/recaptcha/docs/php

客户代码：

require_once('recaptchalib.php');
    $publickey = "**********************"; // you got this from the signup page
    echo recaptcha_get_html($publickey);

在$resp变量上执行了var转储并得到了这个

object(ReCaptchaResponse)#2 (2) { ["is_valid"]=> bool(false) ["error"]=> string(21) "incorrect-captcha-sol" }

还做了一个var_dump recaptcha响应字段,得到了：

NULL

var dump post …

array(7) { ["user"]=> string(0) "" ["pass1"]=> string(0) "" ["pass2"]=> string(0) "" ["email"]=> string(0) "" ["email2"]=> string(0) "" ["gender"]=> string(4) "Male" ["register"]=> string(8) "register" }

var转储请求…

array(10) { ["user"]=> string(0) "" ["pass1"]=> string(0) "" ["pass2"]=> string(0) "" ["email"]=> string(0) "" ["email2"]=> string(0) "" ["gender"]=> string(4) "Male" ["register"]=> string(8) "register" ["PHPSESSID"]=> string(26) "4e79u2fdgrrufvb79einufcmq6" ["cprelogin"]=> string(2) "no" ["cpsession"]=> string(65) ":fX5Z1aWfbsgjGfgb3b3J7koo3Y58y5ntgM6k8GTdrQ4YAcqaywAKnD7PRiayfXv3" }
