NAME

Net::HTTP::API - Easily create client for net API

VERSION

version 0.14

SYNOPSIS

    package My::Net::API;
    use Net::HTTP::API;

    # we declare an API, the base_url is http://exemple.com/api
    # the format is json and it will be append to the query
    # You can set api_base_url later, calling $obj->api_base_url('http://..')
    net_api_declare my_api => (
        api_base_url    => 'http://exemple.com/api',
        api_format      => 'json',
        api_format_mode => 'append',
    );

    # declaring a users method
    # calling $obj->users will call http://exemple.com/api/users/france
    net_api_method users => (
        description => 'this get a list of users',
        method      => 'GET',
        path        => '/users/:country',
        params      => [qw/country/],
    );

    # you can create your own useragent (it must be a LWP::UserAgent object)
    net_api_declare my_api => (
        ...
        useragent => sub {
            my $ua = LWP::UserAgent->new;
            $ua->agent('MyUberAgent/0.23');
            return $ua
        },
        ...
    );

    # if the API require authentification, the module will handle basic
    # authentication for you
    net_api_declare my_api => (
        ...
        authentication => 1,
        ...
    );

    # if the authentication is more complex, you can delegate to your own method

    1;

    my $obj = My::Net::API->new();
    $obj->api_base_url('http://...');
    $obj->foo(user => $user);

DESCRIPTION

Net::HTTP::API is a module to help to easily create a client for a web API.

This module is heavily inspired by what Net::Twitter does.

THIS MODULE IS IN ITS BETA QUALITY. THE API MAY CHANGE IN THE FUTURE

The following roles are added to your class:

Net::HTTP::API::Role::UserAgent
Net::HTTP::API::Role::Format
Net::HTTP::API::Role::Authentication
Net::HTTP::API::Role::Serialization
Net::HTTP::API::Role::Request

The following attributes are added to your class:

api_base_url
api_format
api_username
api_passord
authentication
authentication_method

The following methods are added to your class:

http_request
get_content
serialize
deserialize
content_type

METHODS

net_api_declare
    net_api_declare backtype => (
        base_url    => 'http://api....',
        format      => 'json',
        format_mode => 'append',
    );
api_base_url

The base url for all the API's calls. This will set the api_base_url attribut in your class. Can be set at the object creation or before calling an API method.

api_format

The format for the API's calls. This will set the api_format attribut to your class. Value can be:

json
yaml
xml
api_format_mode

How the format is handled. append will add .$format to the query, content-type will set the content-type information to the header of the request. Should be one the following value:

content-type
append
api_useragent

A LWP::UserAgent object.

    useragent => sub {
        my $ua = LWP::UserAgent->new;
        $ua->agent( "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
        return $ua;
    }
authentication

This is a boolean to tell if we must authenticate to use this API.

authentication_method

The default authentication method only set an authorization header using the Basic Authentication Scheme. You can write your own authentication method:

  net_api_declare foo => (
    ...
    authentication_method => 'my_auth_method',
    ...
  );

  sub my_auth_method {
    my ($self, $req) = @_; #$req is an HTTP::Request object
    ...
  }
net_api_method
description

A string to describe the method (this is a documentation)

method

HTTP method (GET, POST, PUT, DELETE)

path

path of the query.

If you defined your path and params like this

    net_api_method user_comments => (
      ...
      path => '/user/:user/list/:date',
      params => [qw/user date foo bar/],
      ...
    );

and you call

    $obj->user_comments(user => 'franck', date => 'today', foo => 1, bar => 2);

the url generated will look like

    /user/franck/list/today/?foo=1&bar=2
params

Arrayref of params.

required

Arrayref of required params.

params_in_url

When you do a post, the content may have to be sent as arguments in the url, and not as content in the header.
