![允许传入响应 Apache。在 Ubuntu 11.10 上 - Curl](https://linux22.com/image/1309140/%E5%85%81%E8%AE%B8%E4%BC%A0%E5%85%A5%E5%93%8D%E5%BA%94%20Apache%E3%80%82%E5%9C%A8%20Ubuntu%2011.10%20%E4%B8%8A%20-%20Curl.png)
我正在尝试从外部服务器获取 Curl 响应,但是我注意到我既无法 PING 相关服务器也无法连接到它。
我尝试禁用 iptables 防火墙,但没有成功。我的服务器运行在安装了 DD-wrt 固件的 Cisco Linksys WRTN310N 路由器后面。我已经在其中禁用了防火墙。
这是我的网络设置: 配置文件

// Send URL string via CURL
$backendUrl = "https://www.veripayment.com/integration/index.php";
$this->curl->create($backendUrl);
$this->curl->post($post_str);
$return = $this->curl->execute();
$result = array();
// Explode array where blanks are found
$resparray = explode(' ', $return);
if ($resparray)
{
// save results into an array
foreach ($resparray as $resp) {
$keyvalue = explode('=', $resp);
if(isset($keyvalue[1])){
$result[$keyvalue[0]] = str_replace('"', '', $keyvalue[1]);
}
}
}
return $result;
}
这将获得一个空的结果数组。但是,此函数在之前托管该脚本的服务器中运行良好。未进行任何修改

www.veripayment.com 上的服务器(或其前面的防火墙)配置为丢弃 ping 请求。
C:\Users\RGB> ping www.veripayment.com
Pinging veripayment.com [69.172.200.5] with 32 bytes of data:

对于出站 HTTP 请求,您不需要禁用路由器中的任何防火墙。
更新:
您正在使用 PHP 中的 lib_curl,但是我无法识别它。
curl 的其他 PHP 示例使用类似curl_init()
和的函数curl_exec()
我怀疑您需要转储您正在发送的内容(发布数据),比较 PHP 版本并修改代码以检查错误响应。
我不知道您如何使用您正在使用的库来做到这一点,使用其他 PHP curl 库您可以执行以下操作:
if (curl_errno($ch)) {
print curl_error($ch);
} else {
curl_close($ch);
}
我会用一些等效的东西来更新 PHP 脚本。
我猜测你的 PHP 版本和环境与旧服务器上的不一样。
