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.
