💖 Atompub::Client 💖

okay so bestie, welcome to the manual page for Atompub::Client — yes that (3pm) at the end means it's a Perl module manual, and yes I'm about to make the Atom Publishing Protocol feel like a group chat. This is the client. It talks to AtomPub servers so you don't have to. Let's get into it, no cap. 🦋

✨ NAME ✨

Atompub::Client — A client for the Atom Publishing Protocol

🌸 SYNOPSIS 🌸

Here's the whole vibe in code, bestie. Read it top to bottom, it's literally the entire lifecycle:

use Atompub::Client;

my $client = Atompub::Client->new;
$client->username('Melody');
$client->password('Nelson');
#$client->proxy( $proxy_uri );

# Get a Service Document
my $service = $client->getService($service_uri);

my @workspaces = $service->workspaces;
my @collections = $workspaces[0]->collections;

# CRUD an Entry Resource; assuming that the 0-th collection supports
# Entry Resources
my $collection_uri = $collections[0]->href;

my $name = 'New Post';

my $entry = XML::Atom::Entry->new;
$entry->title($name);
$entry->content('Content of my post.');

my $edit_uri = $client->createEntry($collection_uri, $entry, $name);

my $feed = $client->getFeed($collection_uri);
my @entries = $feed->entries;

$entry = $client->getEntry($edit_uri);

$client->updateEntry($edit_uri, $entry);

$client->deleteEntry($edit_uri);

# CRUD a Media Resource; assuming that the 1-st collection supports
# Media Resources
my $collection_uri = $collections[1]->href;

my $name = 'My Photo';

my $edit_uri = $client->createMedia($collection_uri, 'sample1.png',
                                    'image/png', $name);

# Get a href attribute of an "edit-media" link
my $edit_media_uri = $client->resource->edit_media_link;

my $binary = $client->getMedia($edit_media_uri);

$client->updateMedia($edit_media_uri, 'sample2.png', 'image/png');

$client->deleteEntry($edit_media_uri);

# Access to the requested HTTP::Request object
my $request  = $client->request;

# Access to the received HTTP::Response object
my $response = $client->response;

# Access to the received resource (XML::Atom object or binary data)
my $resource = $client->resource;

🫶 DESCRIPTION 🫶

Atompub::Client implements a client for the Atom Publishing Protocol — that's the one described at <http://www.ietf.org/rfc/rfc5023.txt>. iykyk.

And the client is doing a LOT for you, okay? Here's everything it supports:

Authentication 💅 Atompub::Client supports the Basic and WSSE Authentication described in <http://www.intertwingly.net/wiki/pie/DifferentlyAbledClients>.
Service Document 📄 Atompub::Client understands Service Documents, in which information of collections are described, such as URIs, acceptable media types, and allowable categories.
Media Resource support 🖼️ 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.
Media type check ✅ 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.
Category check 🏷️ 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.
Cache controll and versioning ⚡ On-memory cache and versioning, which are controlled by ETag and Last-Modified header, are implemented in Atompub::Client.
Naming resources by Slug header 🐌 The client can specify Slug header when creating a resource, which may be used as part of the resource URI.

(yes, the original really does spell it "controll" — we respect the canon here, bestie 🎀)

👑 METHODS 👑

💜 `Atompub::Client->new([ %options ])`

Creates a new Atompub client object. The options are same as LWP::UserAgent. ✨

💜 `$client->getService($service_uri)`

Retrieves a Service Document at URI $service_uri.

Returns an XML::Atom::Service object on success, false otherwise.

💜 `$client->getCategories($category_uri)`

Retrieves a Category Document at URI $category_uri.

Returns an XML::Atom::Categories object on success, false otherwise.

💜 `$client->getFeed($collection_uri)`

Retrieves a Feed Document from the collection at URI $collection_uri.

Returns an XML::Atom::Feed object, false otherwise.

💜 `$client->createEntry($collection_uri, $entry, [ $slug ])`

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.

💜 `$client->createMedia($collection_uri, $media, $media_type, [ $slug ])`

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.

💜 `$client->getEntry($edit_uri)`

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.

💜 `$client->getMedia($edit_uri)`

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.

💜 `$client->updateEntry($edit_uri, $entry)`

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.

💜 `$client->updateMedia($edit_uri, $media, $media_type)`

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.

💜 `$client->deleteEntry($edit_uri)`

Deletes the Entry Document at URI $edit_uri.

Returns true on success, false otherwise.

💜 `$client->deleteMedia($edit_uri)`

Deletes the Media Resource at URI $edit_uri and related Media Link Entry.

Returns true on success, false otherwise.

🎀 Accessors 🎀

⭐ `$client->username([ $username ])`

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.

⭐ `$client->password([ $password ])`

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.

⭐ `$client->proxy([ $proxy_uri ])`

If called with an argument, sets URI of proxy server like 'http://proxy.example.com:8080'.

Returns the current URI of the proxy server.

⭐ `$client->resource`

⭐ `$client->rc`

An accessor for Entry or Media Resource, which was retrieved in the previous action.

⭐ `$client->request`

⭐ `$client->req`

An accessor for an HTTP::Request object, which was used in the previous action.

⭐ `$client->response`

⭐ `$client->res`

An accessor for an HTTP::Response object, which was used in the previous action.

🧚 INTERNAL INTERFACES 🧚

These are the guts, bestie — the internals doing the behind-the-scenes work. Don't touch unless you know what you're doing. 💅

$client->init
$client->ua — Accessor to the UserAgent.
$client->info — An accessor to information of Collections described in a Service Document.
$client->cache — An accessor to the resource cache.
$client->munge_request($req)
$client->_clear
$client->_get_service(\%args)
$client->_get_categories(\%args)
$client->_get_feed(\%args)
$client->_create_resource(\%args)
$client->_get_resource(\%args)
$client->_update_resource(\%args)
$client->_delete_resource(\%args)

Wait — let me give init and ua their proper label since they share one description: $client->init and $client->ua are both the accessor to the UserAgent. 🫶

😭 ERROR HANDLING 😭

Methods return "undef" on error, and the error message can be retrieved using the errstr method.

not the undef jumpscare 💀 but fr fr, errstr is your bestie when things go sideways.
