NAME

WWW::GoodData::Agent - HTTP client for GoodData JSON-based API

SYNOPSIS

  use WWW::GoodData::Agent;
  my $ua = new WWW::GoodData::Agent;
  my $metadata = $ua->get ('/md');

DESCRIPTION

WWW::GoodData::Agent is HTTP user agent that makes it easy for follow specifics of the GoodData service API, transparently handles conversion to and from JSON content type and recognizes and handles various kinds of exceptions and error states.

It is a subclass of LWP::UserAgent and follows its semantics unless documented otherwise.

PROPERTIES

root

URI object pointing to root of the service API.

This is used to resolve relative request paths.

METHODS

new ROOT, PARAMS

Creates a new agent instance. First argument is root of the service API, the rest is passed to LWP::UserAgent as is.

Compared to stock LWP::UserAgent, it has a memory-backed cookie storage and sets the Accept header to prefer JSON content.

post URI, BODY, PARAMS

Constructs and issues a POST request.

Compared to stock LWP::UserAgent, the extra body parameter is encoded into JSON and set as request content, which is the only way to set the request content.

The rest of parameters are passed to LWP::UserAgent untouched.

put URI, BODY, PARAMS

Constructs and issues a PUT request.

Compared to stock LWP::UserAgent, the extra body parameter is encoded into JSON and set as request content, which is the only way to set the request content.

The rest of parameters are passed to LWP::UserAgent untouched.

delete URI

Convenience method for constructing and issuing a DELETE request.

request PARAMS

This call is common for all request types.

While API is same as stock LWP::UserAgent, relative URIs are permitted and extra content processing is done with the response.

Namely, errors are either handled or turned into exceptions and known content types (JSON) are decoded.
