PHP发送自定义HTTP请求

Question

How can I send a custom HTTP Request to a server whose URL is "http://[IP]:[Port]/"?

What I mean is that, instead of the first line being a normal GET or POST like so:

GET /index.html HTTP/1.1
Host: www.example.com

How can this be replaced with something just like:

CUSTOM
Host: [IP]

I don't mind having to use any additional libraries if necessary such as cURL.

UPDATE:

I've tried using the following cURL code:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://[IP]:[Port]/");
curl_setopt($ch, CURLOPT_PORT, [Port]);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "CUSTOM");

$output = curl_exec($ch);
curl_close($ch);      

print($output);

But it just keeps loading for 2 minutes until it said internal error (both with and without using the CURLOPT_CUSTOMREQUEST). However, if I use a standard website such as http://google.com it'll work fine.

Also I forgot to mention, the port my server is using is 7899, is this ok? Open it in my web browser fine, but cURL doesn't seem to be able to.

Answer 1

Looks like there's nothing wrong with your code. If you're using a shared hosting provider, ask them to open up outbound TCP port 7899.

Answer 2

You can create a custom HTTP request method using the http_request_method_register function:

http://www.php.net/manual/en/function.http-request-method-register.php

This code needs to be run on the server that will be handling the request. If you try to use a non-standard HTTP request method on any old server, depending on the server it may ignore it, or may return an error code.
