弹性WEB托管关于PHP CURL的使用问题？

请问，弹性WEB托管，我在本地服务器上测试正常，但上传到弹性WEB托管服务器后，发现PHP CURL功能用不了。错误信息如下：
error setting certificate verify locations: CAfile: /etc/pki/tls/certs/ca-bundle.crt CApath: none
然后我用阿里云提供的测试样例程序测试，程序代码如下：
<?php
$ch = curl_init();

            curl_setopt($ch, CURLOPT_URL, "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=wxf6572b80d4236dd82347c&corpsecret=4j46JIVgBm_kpwiOpzmOdn7S9yegVygjrUcwpvgYnoICbAJj1w9OxHjNGYBo9HWgsdf");   
            curl_setopt($ch, CURLOPT_HEADER, false);
            #curl_setopt($ch, CURLOPT_TIMEOUT_MS, 30);
            #curl_setopt($ch, CURLOPT_CONNECTTIMEOUT_MS, 10000);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            $response = curl_exec($ch);
            $curl_errno = curl_errno($ch);
        $curl_error = curl_error($ch);
            curl_close($ch);

echo $response."
".$curl_error ;
?>

本地执行提示以下错误信息：
SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
上传到阿里云弹性服务器，提示如下错误信息：
error setting certificate verify locations: CAfile: /etc/pki/tls/certs/ca-bundle.crt CApath: none

附我个人的部分程序代码：
<?php
//调用微信企业号接口发送通报信息的PHP代码
function curlPost($url,$data="")
{

$ch = curl_init();
$opt = array(
        CURLOPT_URL     => $url,            
        CURLOPT_HEADER  => 0,
        CURLOPT_POST    => 1,
        CURLOPT_POSTFIELDS      => $data,
        CURLOPT_RETURNTRANSFER  => 1,
        CURLOPT_TIMEOUT         => 20
        );
$ssl = substr($url,0,8) == "https://" ? TRUE : FALSE;
if ($ssl){
    $opt[CURLOPT_SSL_VERIFYHOST] = 1;
    $opt[CURLOPT_SSL_VERIFYPEER] = FALSE;
}
curl_setopt_array($ch,$opt);
$data = curl_exec($ch);
  $curl_errno = curl_errno($ch);
  $curl_error = curl_error($ch);
  echo $curl_error;
curl_close($ch);
return $data;

}

/*
Call to undefined function curl_init
解决方法如下：
1.打开php.ini，开启extension=php_curl.dll
2.检查php.ini的extension_dir值是哪个目录，检查有无php_curl.dll，没有的请下载php_curl.dll，再把php目录中的libeay32.dll,ssleay32.dll拷到c:windowssystem32里面
修改之后还有问题啊
在httpd.conf文件中加上：
LoadFile 动态链接库的完整路径
比如，此处php需要扩展curl，因此解决方法就是在httpd.conf文件中加上：
LoadFile C:/Apache2.2/php-5.2.1/libeay32.dll
LoadFile C:/Apache2.2/php-5.2.1/ssleay32.dll
这样就解决了

以上情况是什么原因，请求支持！ tkt1020@163.com
