What Is HTTP::Request?

This section describes what is HTTP::Response - a Perl class that represents the HTTP request message to be sent to a Web server.

If you are only using get() and post() methods, then you don't need to know the HTTP::Request class and objects. The get() or post() method will automatically create the HTTP::Request object for you. But if you want to create your own special HTTP request, you need to learn the HTTP::Request class.

What Is HTTP::Request? HTTP::Request, developed by Gisle Aas, is a Perl class that represents the HTTP request message to be sent to a Web server. An HTTP response consists of a request line, some headers, and a content body.

The current version of HTTP::Response is 6.00, which supports the following properties and methods:

C:\herong>perl -e "use LWP::UserAgent; 
   print((new LWP::UserAgent())
   ->get('http://herongyang.com')->request()->as_string());"

GET http://herongyang.com
User-Agent: libwww-perl/6.05

It worked!. The HTTP::Request object created by the LWP::UserAgent class was so simple and short.

Here is how the code works:
