我在codeigniter中有一个网站，该网站在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，因为其中使用了重新接收。
现在显示Could not open socket错误。
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";
}
这是recaptchalib.php代码：

那么我该如何解决这个问题？
答案 0 :(得分：6)
我得到了同样的错误，尝试了一些建议，但没有任何结果。
所以我记录了网络流量并对其进行了分析。它显示的是中间连接，服务器从ipv4更改为ipv6，我记得在某处读取recaptcha在ipv6上有问题。
所以我将@fsockopen($host, [...]更改为@fsockopen(gethostbyname($host), [...]，然后重新开始工作。
答案 1 :(得分：6)
对于SSL（https），请使用：
echo recaptcha_get_html($publickey,true);
而不是：
echo recaptcha_get_html($publickey);
这是因为recaptchalib.php中的recaptcha_get_html（）（获取扭曲的文本图像）默认为http，除非你另有说明。
答案 2 :(得分：3)
你需要告诉函数＆＃34; recaptcha_get_html（）＆＃34;你想使用https。用
替换recaptcha_get_html（$ publickey）echo recaptcha_get_html($publickey,null,1);
答案 3 :(得分：3)
像这样编辑recaptchalib.php：
找到这一行 - 函数recaptcha_get_html（$ pubkey，$ error = null，$ use_ssl = false）
将其更改为 - function recaptcha_get_html（$ pubkey，$ error = null，$ use_ssl = true）
参数$ use_ssl从false变为true ...休息将由脚本处理..
答案 4 :(得分：2)
我得到了同样的错误，尝试了所有的建议，但对我没什么用。
然后我确实分析了问题，然后我收到了SSL证书问题
此证书仅对以下名称有效：www.google.com （错误代码：ssl_error_bad_cert_domain）
所以我改变了
echo recaptcha_get_html($publickey,,true);
@fsockopen($host, [...] to @fsockopen(gethostbyname($host), [...]
与
一起定义（ “RECAPTCHA_API_SECURE_SERVER”， “https://api-secure.recaptcha.net”）;
到
定义（ “RECAPTCHA_API_SECURE_SERVER”， “https://www.google.com/recaptcha/api”）;
在recaptchalib.php中，recaptcha再次工作。
答案 5 :(得分：0)
您需要在“recaptchalib.php”文件中将所有http：//网址更改为https：//，然后才能生效。
答案 6 :(得分：0)
从脚本源网址中删除“ http：”。
更改它：
