如何为curl设置https foward代理 [英] How to set up a https foward proxy for curl
问题描述
我遇到了一个问题，没有在google上找到解决方法
我尝试使用curl访问代理后面的https网站，但失败.
没有代理或没有ssl的访问都是成功.然后，我部署了一个TCP代理(从 https://github.com/kklis/proxy 获得)，并设置环境 export https_proxy = 127.0.0.1:443
访问 https://www.baidu.com ，我只是连接中止错误
这是我运行代理的方式:
I am facing one problem, and not get solution on google
I try to use curl to visit a https website behind a proxy but fail.
It is success without proxy or visit without ssl. Then I deployed a tcp proxy (got from https://github.com/kklis/proxy), and set enviroment export https_proxy=127.0.0.1:443
visit https://www.baidu.com, I just got connection aborted error
Here is how I run proxy:
./proxy -l 8111 -h www.baidu.com -p 443
并设置代理环境:
导出https_proxy = 127.0.0.1:8111
运行curl:
curl -v https://www.baidu.com
得到结果:
./proxy -l 8111 -h www.baidu.com -p 443
And set proxy environment:
export https_proxy=127.0.0.1:8111
Run curl:
curl -v https://www.baidu.com
Got result:
将URL重建为: https://www.baidu.com/
尝试127.0.0.1 ...
已连接到127.0.0.1(127.0.0.1)端口8111(#0)
建立到www.baidu.com的HTTP代理隧道:443
连接www.baidu.com:443 HTTP/1.1
主持人:www.baidu.com:443
用户代理:curl/7.47.0
代理连接:保持活动
代理CONNECT中止
与主机127.0.0.1的连接#0保持不变
curl:(56)代理CONNECT中止了
Rebuilt URL to: https://www.baidu.com/
Trying 127.0.0.1...
Connected to 127.0.0.1 (127.0.0.1) port 8111 (#0)
Establish HTTP proxy tunnel to www.baidu.com:443
CONNECT www.baidu.com:443 HTTP/1.1
Host: www.baidu.com:443
User-Agent: curl/7.47.0
Proxy-Connection: Keep-Alive
Proxy CONNECT aborted
Connection #0 to host 127.0.0.1 left intact
curl: (56) Proxy CONNECT aborted
我尝试添加-不安全并且不起作用，结果相同.
I tried add --insecure and not work, same result.
我认为这与某些人遇到的问题相同，但仍然没有答案: https://github.com/h2non/balboa/issues/1
I think this is the same issue some one has met, still no answer: https://github.com/h2non/balboa/issues/1
谢谢任何人的帮助！
推荐答案
我想我知道原因
我捕获了数据包，使用代理访问https网站，curl将启动HTTP CONNECT方法以建立隧道.隧道应该在curl客户端和代理之间，但是TCP代理会将所有消息传递到Web服务器，因此Web服务器将重置连接.
转发代理不应该只是在客户端和Web服务器之间传递消息，还应该了解HTTP CONNECT方法
我使用标准的前向代理-鱿鱼代替，然后成功.
希望这会有所帮助
I think I know the reason
I captured packets , using proxy to visit a https website , curl will start a HTTP CONNECT method to establish a tunnel. The tunnel should be between curl client and proxy, but TCP proxy will delivery all messages to web server, so web server will reset the connection.
A forward proxy should not just delivery messages between client and web server.It should understand the HTTP CONNECT method
I use a standard foward proxy - squid instead, then success.
Hope this helps
