如何从php CURL请求中删除标头“ Proxy-Connection：Keep-Alive”？

Question

I'm am trying to access a webpage using an HTTP proxy with curl and php. I want to make the request look as close as possible to a real browser, however when I send the GET request through CURL, it sends the header "Proxy-Connection: Keep-Alive" even when I haven't specified it. How can I remove "Proxy-Connection: Keep-Alive" from the sent headers?

Answer 1

尝试使用-H参数而不为要删除的内部标头指定值：

curl -H "Proxy-Connection:" http://somehost

Answer 2

If you're using recent version of curl, you should use --proxy-header option:

curl --proxy-header "Proxy-Connection:" http://somehost

This is CURLOPT_PROXYHEADER option in php which available starting from php 7.0.7.
