问题
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
And set proxy environment:
export https_proxy=127.0.0.1:8111
Run curl:
curl -v https://www.baidu.com
Got result:
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
I tried add --insecure and not work, same result.
I think this is the same issue some one has met, still no answer: https://github.com/h2non/balboa/issues/1
Thanks if anyone can help!
回答1:
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
