PHP通过代理连接到HTTPS站点 [英] PHP connect to HTTPS site through proxy

问题描述

我遇到了以下问题：有一个HTTPS网站，我需要通过代理连接到它。以下是我的cURL setopts：

I've got the following problem: there is an HTTPS web site, and I need to connect to it through a proxy. Here are my cURL setopts:

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, '100.100.100.100:8080');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HEADER, 1); 
curl_setopt($ch, CURLOPT_USERAGENT, $ua);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

echo curl_error($ch);

输出连接到######。com：8080;无错误

outputs Failed connect to ######.com:8080; No error

其中100.100.100.100：8080是有效HTTPS代理的占位符。这不起作用。如何通过代理使cURL连接到HTTPS网站？我真的很想要一个不仅可以通过HTTPS代理工作的灵魂。另外，我最喜欢使用cURL的方法，但是如果有更好的方法，没有cURL，我可以改用它。

Where 100.100.100.100:8080 is a placeholder for a valid HTTPS proxy. This doesn't work. How do I make cURL connect to an HTTPS website through a proxy? I would really like a soultion that would work through not only HTTPS proxies. Also, I would best prefer a method using cURL, but if there is a better way to do it, without cURL, I could use it instead.

推荐答案

更新：
添加

curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);

它将阻止您的HTTP代理解析您的请求标头并采取更透明的行为 - 就像隧道一样。

It will prevent your HTTP proxy to parse your request headers and to act more transparently - like a tunnel.

初步回答，不感兴趣

您的代码看起来不错，我假设您检查了琐碎的问题，因此问题可能是SSL证书验证失败。如果证书是通过示例自签名的话就是这种情况。
尝试

Your code looks OK, and I assume you checked the trivial issues, so the problem is probably that the SSL certificate verification fails. It's the case if the certificate is self signed by example. Try

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

允许允许使用自签名证书的请求。

to allow a request that allows using a self signed certificate.
