问题描述

示例网址：
https ：//www.tescogoldexchange.com/gold-calculator.aspx？carat = 9& weight = 1& ref = miniQuote

我想使用cURL以获取HTTPS页面的内容。

I am trying to use cURL to get the contents of an HTTPS page.

问题是我无法抓取文档，我不知道为什么。

Problem is that I am not able to grab the document and I have no idea why.

    function download_page($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)");

    return curl_exec($ch);
}

推荐答案

同一问题这家伙正在进入。而且，他似乎已经固定了。问题可能是关于SSL证书的协商，以及cURL应该如何告知服务器正在发送的证书，可以信任。

You're likely running into the same issue this guy is running into. And, he seems to have fixed it. The problem probably is the negotiation about the SSL certificate and how cURL should tell that the certificate the server is sending, can be trusted.
