Zend_Service_Delicious is simple API for using
del.icio.us
XML and JSON web services. This component gives you read-write access to posts at del.icio.us
if you provide credentials. It also allows read-only access to public data of all users.
Пример 35.14. Get all posts
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
$posts = $delicious->getAllPosts();
foreach ($posts as $post) {
echo "--\n";
echo "Title: {$post->getTitle()}\n";
echo "Url: {$post->getUrl()}\n";
}
Zend_Service_Delicious provides three methods for retrieving posts: getPosts(),
getRecentPosts() and getAllPosts(). All of these
methods return an instance of Zend_Service_Delicious_PostList, which
holds all retrieved posts.
<?php
/**
* Get posts matching the arguments. If no date or url is given, most recent date will be used.
*
* @param string $tag Optional filtering by tag
* @param Zend_Date $dt Optional filtering by date
* @param string $url Optional filtering by url
* @return Zend_Service_Delicious_PostList
*/
public function getPosts($tag = null, $dt = null, $url = null);
/**
* Get recent posts
*
* @param string $tag Optional filtering by tag
* @param string $count Maximal number of posts to be returned (default 15)
* @return Zend_Service_Delicious_PostList
*/
public function getRecentPosts($tag = null, $count = 15);
/**
* Get all posts
*
* @param string $tag Optional filtering by tag
* @return Zend_Service_Delicious_PostList
*/
public function getAllPosts($tag = null);
Instances of this class are returned by the getPosts(), getAllPosts(),
getRecentPosts(), and getUserPosts() methods of Zend_Service_Delicious.
For easier data access this class implements the Countable, Iterator, and
ArrayAccess interfaces.
Пример 35.15. Accessing post lists
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
$posts = $delicious->getAllPosts();
// count posts
echo count($posts);
// iterate over posts
foreach ($posts as $post) {
echo "--\n";
echo "Title: {$post->getTitle()}\n";
echo "Url: {$post->getUrl()}\n";
}
// get post using array access
echo $posts[0]->getTitle();

Post list objects have two built-in filtering capabilities. Post lists may be filtered by tags and by URL.
Пример 35.16. Filtering a Post List with Specific Tags
Posts may be filtered by specific tags using withTags(). As a convenience,
withTag() is also provided for when only a single tag needs to be specified.
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
$posts = $delicious->getAllPosts();
// Print posts having "php" and "zend" tags
foreach ($posts->withTags(array('php', 'zend')) as $post) {
echo "Title: {$post->getTitle()}\n";
echo "Url: {$post->getUrl()}\n";
}
Пример 35.17. Filtering a Post List by URL
Posts may be filtered by URL matching a specified regular expression using the withUrl()
method:
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
$posts = $delicious->getAllPosts();
// Print posts having "help" in the URL
foreach ($posts->withUrl('/help/') as $post) {
echo "Title: {$post->getTitle()}\n";
echo "Url: {$post->getUrl()}\n";
}
Пример 35.18. Post editing
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
$posts = $delicious->getPosts();
// set title
$posts[0]->setTitle('New title');
// save changes
$posts[0]->save();
Пример 35.19. Method call chaining
Every setter method returns the post object so that you can chain method calls using a fluent interface.
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
$posts = $delicious->getPosts();
$posts[0]->setTitle('New title')
->setNotes('New notes')
->save();
There are two ways to delete a post, by specifying the post URL or by calling the delete()
method upon a post object.
Пример 35.20. Deleting posts
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
// by specifying URL
$delicious->deletePost('http://framework.zend.com');
// or by calling the method upon a post object
$posts = $delicious->getPosts();
$posts[0]->delete();
// another way of using deletePost()
$delicious->deletePost($posts[0]->getUrl());
To add a post you first need to call the createNewPost() method, which returns a
Zend_Service_Delicious_Post object. When you edit the post, you need to save it
to the del.icio.us database by calling the save() method.
Пример 35.21. Adding a post
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
// create a new post and save it (with method call chaining)
$delicious->createNewPost('Zend Framework', 'http://framework.zend.com')
->setNotes('Zend Framework Homepage')
->save();
// create a new post and save it (without method call chaining)
$newPost = $delicious->createNewPost('Zend Framework', 'http://framework.zend.com');
$newPost->setNotes('Zend Framework Homepage');
$newPost->save();
Пример 35.22. Tags
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
// get all tags
print_r($delicious->getTags());
// rename tag ZF to zendFramework
$delicious->renameTag('ZF', 'zendFramework');
Пример 35.23. Bundles
<?php
$delicious = new Zend_Service_Delicious('username', 'password');
// get all bundles
print_r($delicious->getBundles());
// delete bundle someBundle
$delicious->deleteBundle('someBundle');
// add bundle
$delicious->addBundle('newBundle', array('tag1', 'tag2'));
The del.icio.us web API allows access to the public data of all users.
Таблица 35.10. Methods for retrieving public data
| Name | Description | Return type |
|---|---|---|
getUserFans() |
Retrieves fans of a user | Array |
getUserNetwork() |
Retrieves network of a user | Array |
getUserPosts() |
Retrieves posts of a user | Zend_Service_Delicious_PostList |
getUserTags() |
Retrieves tags of a user | Array |
|
Замечание |
|---|---|
When using only these methods, a username and password combination is not required when constructing
a new |
Пример 35.24. Retrieving public data
<?php
// username and password are not required
$delicious = new Zend_Service_Delicious();
// get fans of user someUser
print_r($delicious->getUserFans('someUser'));
// get network of user someUser
print_r($delicious->getUserNetwork('someUser'));
// get tags of user someUser
print_r($delicious->getUserTags('someUser'));
When retrieving public posts with the getUserPosts() method, a
Zend_Service_Delicious_PostList object is returned, and it contains
Zend_Service_Delicious_SimplePost objects, which contain basic information
about the posts, including URL, title, notes, and tags.
Таблица 35.11. Methods of the Zend_Service_Delicious_SimplePost class
| Name | Description | Return type |
|---|---|---|
getNotes() |
Returns notes of a post | String |
getTags() |
Returns tags of a post | Array |
getTitle() |
Returns title of a post | String |
getUrl() |
Returns URL of a post | String |
Zend_Service_Delicious uses Zend_Rest_Client for making HTTP requests
to the del.icio.us web service. To change which HTTP client Zend_Service_Delicious
uses, you need to change the HTTP client of Zend_Rest_Client.
Пример 35.25. Changing the HTTP client of Zend_Rest_Client
<?php
$myHttpClient = new My_Http_Client();
Zend_Rest_Client::setHttpClient($myHttpClient);
When you are making more than one request with Zend_Service_Delicious to speed your
requests, it's better to configure your HTTP client to keep connections alive.
Пример 35.26. Configuring your HTTP client to keep connections alive
<?php
Zend_Rest_Client::getHttpClient()->setConfig(array(
'keepalive' => true
));
