NAME¶

HTTP::OAI::UserAgent - Extension of the LWP::UserAgent for OAI HTTP requests

DESCRIPTION¶

This module provides a simplified mechanism for making requests to an OAI repository, using the existing LWP::UserAgent module.

SYNOPSIS¶

        require HTTP::OAI::UserAgent;
        my $ua = new HTTP::OAI::UserAgent;
        my $response = $ua->request(
                baseURL=>'http://arXiv.org/oai1',
                verb=>'ListRecords',
                from=>'2001-08-01',
                until=>'2001-08-31'
        );
        print $response->content;

METHODS¶

$ua = new HTTP::OAI::UserAgent(proxy=>'www-cache',...)

This constructor method returns a new instance of a HTTP::OAI::UserAgent module. All arguments are passed to the LWP::UserAgent constructor.

$r = $ua->request($req)

Requests the HTTP response defined by $req, which is a HTTP::Request object.

$r = $ua->request(baseURL=>$baseref, verb=>$verb, %opts)

Makes an HTTP request to the given OAI server (baseURL) with OAI arguments. Returns an HTTP::Response object.

OAI-PMH related options:

        from => $from
        until => $until
        resumptionToken => $token
        metadataPrefix => $mdp
        set => $set
    

$str = $ua->url(baseURL=>$baseref, verb=>$verb, ...)

Takes the same arguments as request, but returns the URL that would be requested.

$time_d = $ua->delay( $time_d )

Return and optionally set a time (in seconds) to wait between requests. $time_d may be a CODEREF.
