summary: Consume external data through their RESTFul interfaces.
# Restful Service # Restful Service
## Introduction `[api:RestfulService]` is used to enable connections to remote web services through PHP's `curl` command. It provides an
interface and utility functions for generating a valid request and parsing the response returned from the web service.
`[api:RestfulService]` uses the php curl library, enabling connections to remote web services which support a REST interface and consuming those web services. (Examples: [Flickr](http://www.flickr.com/services/api/), [Youtube](http://code.google.com/apis/youtube/overview.html), Amazon and etc). `[api:RestfulService]` can parse the XML response (sorry no JSON support)
returned from the web service. Further it supports caching of the response, and you can customize the cache interval.
To gain the functionality you can either create a new `[api:RestfulService]` object or create a class extending the
RestfulService (see [flickrservice](http://silverstripe.org/flickr-module/) and
[youtubeservice](http://silverstripe.org/youtube-gallery-module/) modules).
<div class="alert" markdown="1">
RestfulService currently only supports XML. It has no JSON support at this stage.
</div>
## Examples ## Examples
### Creating a new RestfulObject ### Creating a new RestfulObject
:::php `getWellingtonWeather` queries the Yahoo Weather API for an XML file of the latest weather information. We pass a query
//example for using RestfulService to connect and retrive latest twitter status of an user. string parameter `q` with the search query and then convert the resulting XML data to an `ArrayList` object to display
$twitter = new RestfulService("http://twitter.com/statuses/user_timeline/user.xml", $cache_expiry ); in the template.
$params = array('count' => 1);
$twitter->setQueryString($params);
$conn = $twitter->request();
$msgs = $twitter->getValues($conn, "status");

'q' => 'select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="Wellington, NZ")'
));
// perform the query
$conn = $fetch->request();
public function __construct($expiry=NULL){ // parse the XML body

## Best Practices ## Best Practices
### Handling Errors ### Handling Errors
If the web service returned an error (for example, API key not available or inadequate parameters) `[api:RestfulService]` If the web service returned an error (for example, API key not available or inadequate parameters),
could delgate the error handling to it's descendant class. To handle the errors define a function called errorCatch `[api:RestfulService]` can delegate the error handling to it's descendant class. To handle the errors, subclass
`RestfulService and define a function called errorCatch.
:::php :::php
// This will raise Youtube API specific error messages (if any). <?php
public function errorCatch($response){
$err_msg = $response; class MyRestfulService extends RestfulService {
if(strpos($err_msg, '<') === false) {
user_error("YouTube Service Error : $err_msg", E_USER_ERROR); public function errorCatch($response) {
$err_msg = $response;
if(strpos($err_msg, '<') === false) {
user_error("YouTube Service Error : $err_msg", E_USER_ERROR);
}
return $response;
} }
return $response;
} }
If you want to bypass error handling, define `checkErrors` in the constructor for `RestfulService`
If you want to bypass error handling on your sub-classes you could define that in the constructor.
:::php :::php
public function __construct($expiry=NULL){ <?php
parent::__construct('http://www.flickr.com/services/rest/', $expiry);
$this->checkErrors = false; //Set checkErrors to false to bypass error checking
}
class MyRestfulService extends RestfulService {
## Other Uses public function __construct($expiry = NULL) {
parent::__construct('http://www.flickr.com/services/rest/', $expiry);
### How to use `[api:RestfulService]` to easily embed an RSS feed
$this->checkErrors = false;
`[api:RestfulService]` can be used to easily embed an RSS feed (since it's also an xml response) from a site
such as del.icio.us
Put something like this code in mysite/code/Page.php inside class Page_Controller
:::php
// Accepts an RSS feed URL and outputs a list of links from it
public function RestfulLinks($url){
$service = new RestfulService($url);
$request = $service->request();
$body = $request->getBody();
$items = $service->getValues($body,"channel","item");
$output = '';
foreach($items as $item) {
// Fix quote encoding
$description = str_replace('&amp;quot;', '&quot;', $item->description);
$output .= "<li><a href=\"{$item->link}\">{$item->title}</a><br />{$description}</li>";
} }
return $output;
} }

$list = $this->getStudents(), Player::get(),

title: A custom CSVBulkLoader instance
# How to: A custom CSVBulkLoader instance
A an implementation of a custom `CSVBulkLoader` loader. In this example. we're provided with a unique CSV file
containing a list of football players and the team they play for. The file we have is in the format like below.
"SpielerNummer", "Name", "Geburtsdatum", "Gruppe"
11, "John Doe", 1982-05-12,"FC Bayern"
12, "Jane Johnson", 1982-05-12,"FC Bayern"
13, "Jimmy Dole",,"Schalke 04"
This data needs to be imported into our application. For this, we have two `DataObjects` setup. `Player` contains
information about the individual player and a relation set up for managing the `Team`.
**mysite/code/Player.php**.
:::php
<?php
class Player extends DataObject {
private static $db = array(
'PlayerNumber' => 'Int',
'FirstName' => 'Text',
'LastName' => 'Text',
'Birthday' => 'Date'
);
private static $has_one = array(
'Team' => 'FootballTeam'
);
}
**mysite/code/FootballTeam.php**
:::php
<?php
class FootballTeam extends DataObject {
private static $db = array(
'Title' => 'Text'
);
private static $has_many = array(
'Players' => 'Player'
);
}
Now going back to look at the CSV, we can see that what we're provided with does not match what our data model looks
like, so we have to create a sub class of `CsvBulkLoader` to handle the unique file. Things we need to consider with
the custom importer are:
* Convert property names (e.g Number to PlayerNumber) through providing a `$columnMap`.
* Split a combined "Name" field into `FirstName` and `LastName` by calling `importFirstAndLastName` on the `Name`
column
* Prevent duplicate imports by a custom `$duplicateChecks` definition.
* Create a `Team` automatically based on the `Gruppe` column and a entry for `$relationCallbacks`
Our final import looks like this.
**mysite/code/PlayerCsvBulkLoader.php**
:::php
<?php
class PlayerCsvBulkLoader extends CsvBulkLoader {
public $columnMap = array(
'Number' => 'PlayerNumber',
'Name' => '->importFirstAndLastName',
'Geburtsdatum' => 'Birthday',
'Gruppe' => 'Team.Title',
);
public $duplicateChecks = array(
'SpielerNummer' => 'PlayerNumber'
);
public $relationCallbacks = array(
'Team.Title' => array(
'relationname' => 'Team',
'callback' => 'getTeamByTitle'
)
);
public static function importFirstAndLastName(&$obj, $val, $record) {
$parts = explode(' ', $val);
if(count($parts) != 2) return false;
$obj->FirstName = $parts[0];
$obj->LastName = $parts[1];
}
public static function getTeamByTitle(&$obj, $val, $record) {
return FootballTeam::get()->filter('Title', $val)->First();
}

title: Embed an RSS Feed
# Embed an RSS Feed
`[api:RestfulService]` can be used to easily embed an RSS feed from a site. In this How to we'll embed the latest
weather information from the Yahoo Weather API.
First, we write the code to query the API feed.
**mysite/code/Page.php**
:::php
public function getWellingtonWeather() {
$fetch = new RestfulService(
'https://query.yahooapis.com/v1/public/yql'
);
$fetch->setQueryString(array(
'q' => 'select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="Wellington, NZ")'
));
// perform the query
$conn = $fetch->request();
// parse the XML body
$msgs = $fetch->getValues($conn->getBody(), "results");
// generate an object our templates can read
$output = new ArrayList();
if($msgs) {
foreach($msgs as $msg) {
$output->push(new ArrayData(array(
'Description' => Convert::xml2raw($msg->channel_item_description)
)));
}
}
return $output;
}
This will provide our `Page` template with a new `WellingtonWeather` variable (an [api:ArrayList]). Each item has a
single field `Description`.
**mysite/templates/Page.ss**
:::ss
<% if WellingtonWeather %>
<% loop WellingtonWeather %>
$Description
