Atompub::Client implements a client for the Atom Publishing Protocol described at <http://www.ietf.org/rfc/rfc5023.txt>.
The client supports the following features:
Atompub::Client supports the Basic and WSSE Authentication described in <http://www.intertwingly.net/wiki/pie/DifferentlyAbledClients>.
Atompub::Client understands Service Documents, in which information of collections are described, such as URIs, acceptable media types, and allowable categories.
Media Resources (binary data) as well as Entry Resources are supported. You can create and edit Media Resources such as image and video by using Atompub::Client.
Atompub::Client checks media types of resources before creating and editing them to the collection. Acceptable media types are shown in app:accept elements in the Service Document.
Atompub::Client checks categories in Entry Resources before creating and editing them to the collection. Allowable categories are shown in app:categories elements in the Service Document.
On-memory cache and versioning, which are controlled by ETag and Last-Modified header, are implemented in Atompub::Client.
The client can specify Slug header when creating a resource, which may be used as part of the resource URI.
Creates a new Atompub client object. The options are same as LWP::UserAgent.
Retrieves a Service Document at URI $service_uri.
Returns an XML::Atom::Service object on success, false otherwise.
Retrieves a Category Document at URI $category_uri.
Returns an XML::Atom::Categories object on success, false otherwise.
Retrieves a Feed Document from the collection at URI $collection_uri.
Returns an XML::Atom::Feed object, false otherwise.
Creates a new entry in the collection at URI $collection_uri.
$entry must be an XML::Atom::Entry object.
If $slug is provided, it is set in Slug header and may be used as part of the resource URI.
Returns a Location header, which contains a URI of the newly created resource, or false on error.
Creates a new Media Resource and a Media Link Entry in the collection at URI $collection_uri.
If $media is a reference to a scalar, it is treated as the binary. If a scalar, treated as a file containing the Media Resource.
$media_type is the media type of the Media Resource, such as 'image/png'.
$slug is set in the Slug header, and may be used as part of the resource URI.
Returns a Location header, which contains a URI of the newly created resource, or false on error.
Retrieves an Entry Document with the given URI $edit_uri.
Returns an XML::Atom::Entry object on success, false otherwise. If the server returns 304 (Not Modified), returns a cache of the Media Resource.
Retrieves a Media Resource with the given URI $edit_uri.
Returns binary data of the Media Resource on success, false otherwise. If the server returns 304 (Not Modified), returns a cache of the Media Resource.
Updates the Entry Document at URI $edit_uri with the new Entry Document $entry, which must be an XML::Atom::Entry object.
Returns true on success, false otherwise.
Updates the Media Resource at URI $edit_uri with the $media.
If $media is a reference to a scalar, it is treated as the binary. If a scalar, treated as a file containing the Media Resource.
$media_type is the media type of the Media Resource, such as 'image/png'.
Returns true on success, false otherwise.
Deletes the Entry Document at URI $edit_uri.
Returns true on success, false otherwise.
Deletes the Media Resource at URI $edit_uri and related Media Link Entry.
Returns true on success, false otherwise.
If called with an argument, sets the username for login to $username.
Returns the current username that will be used when logging in to the Atompub server.
If called with an argument, sets the password for login to $password.
Returns the current password that will be used when logging in to the Atompub server.
If called with an argument, sets URI of proxy server like 'http://proxy.example.com:8080'.
Returns the current URI of the proxy server.
An accessor for Entry or Media Resource, which was retrieved in the previous action.
An accessor for an HTTP::Request object, which was used in the previous action.
An accessor for an HTTP::Response object, which was used in the previous action.
Accessor to the UserAgent.
An accessor to information of Collections described in a Service Document.
An accessor to the resource cache.
Methods return "undef" on error, and the error message can be retrieved using the errstr method.
