如何使用 Apache HttpComponents Client 请求 CONNECT

Question

Apache says:

"HttpComponents Client is a successor of and replacement for Commons HttpClient 3.x. Users of Commons HttpClient are strongly encouraged to upgrade."

In package org.apache.http.client.methods almost all Http methods are supported:

• OPTIONS (HttpOptions)
• GET (HttpGet)
• HEAD (HttpHead)
• PATCH (HttpPatch)
• POST (HttpPost)
• PUT (HttpPut)
• DELETE (HttpDelete)
• TRACE (HttpTrace)

But what is with the method CONNECT? How to execute a CONNECT request?

("Before" in org.apache.commons.httpclient there exist the ConnectMethod for method CONNECT.)

Answer 1

One can easily create a CONNECT request but I am not entirely sure what you intent to do with it

HttpRequest connect = new BasicHttpRequest("CONNECT", "somehost:80");

HttpClient creates CONNECT requests internally when establishing an SSL tunnel through a proxy server.
