DESCRIPTION

This class provides a basic and easy to use support for the client-side HTTP. It is supplied in order to avoid dependency on LWP. If such dependency is not a problem, consider to use LWP instead that provides much better support for HTTP and other protocols.

METHODS

The following class methods are available:

get, post, request_url, error, error_with_url, network_error, response_code, response_codestr, response_error, response_headers, response_content.
get
url [params ...]

Execute HTTP get of the given url and return the html string or undef on network/response error. Use other methods to get the details about the error and the response.

params is key-value hash, the following keys are supported:

    url_host            − only used if url is none
    url_port            − only used if url is none (80)
    url_path            − only used if url is none
    endl                − default is "\015\012"
    timeout             − default is 20 seconds
    user_agent          − default is "Arch::LiteWeb/0.1"
    nocache             − add a no−cache header
    noredirect          − don't follow redirect responses
    max_redirect_depth  − default is 5
    use_proxy           − default is false
    proxy_url           − proxy url ($http_proxy supported too)
    proxy_host          − only used if proxy_url is none
    proxy_port          − only used if proxy_url is none (80)

post url input [params]

Not implemented yet.

request_url

Actual url of the last issued request or undef. If partial redirect responses are enabled, then the result is the last (non-redirect) url.

error

If the last request resulted in error (i.e. get/post returned undef), then this method returns the error message, otherwise it returns undef. This is just a shortcut for network_error || response_error.

error_with_url

Like error, but with "\nwhile fetching request_url\n" text appended if non undef.

network_error

The network error message for the last request or undef.

response_error

The response error message for the last request or undef.

response_code

The last response code (integer) or undef.

response_codestr

The last response code (string) or undef.

response_headers

The last response headers (hashref of HTTP headers) or undef.

response_content

The last response content or undef. This is the same thing that the last get/post returns.

BUGS

Not intended for use in mission-critical applications.
