1.1	4
10.5	5	XWiki provides fine-grain access to virtually every element through an API that is based on HTTP semantics, i.e., a RESTful API. In this page you will find all the details to take advantage of this API and the instructions to use it at its full potential.

28.1	7	See also this [[tutorial by Fabio Mancinelli>>http://blog.fabiomancinelli.org/2011/03/07/XWikis_RESTful_API.html]].

20.1	9	= Accessing the service =
16.1	10
17.1	11	By defaut the XWiki RESTful API entrypoint is rooted at the following URI:
	12
	13	{{code}}
	14
	15	http://host:port/xwiki/rest
	16
	17	{{/code}}
	18
17.2	19	All the resource references described in the [[XWiki RESTful API Documentation>>#HXWikiRESTfulAPIDocumentation]] should be intended relative to this URL.
17.1	20
28.2	21	For example the ##/wikis## resources on a server running on ##localhost## on port ##8080## can be retrieved using the following URL : ##http:~/~/localhost:8080/xwiki/rest/wikis##
17.1	22
26.2	23	In addition to retrieving content in XML format, you can also retrieve it in JSON format by adding the parameter ##?media=json## in the URL. For example: ##http:~/~/localhost:8080/xwiki/rest/wikis?media=json##
25.1	24
14.2	25	= Dataset =
1.1	26
	27	This section contains a brief and high-level description of the XWiki data set that should serve as a basis for presenting resources and their associated operations.
	28
10.3	29	XWiki has pages organized in spaces. Each page is available in multiple versions (its history) and translations. Translated pages have their own versions and history which are independent. Each page might have attachments. Each attachment has its own history. Attachments are shared among all the different translations of a page (i.e., the same set of attachments is the same regardless of the page language). Pages can have one or more objects. Objects are instances of a class that contains a set of properties. Some objects might be directly exposed as first class entities, such as comments and tags. Objects, as attachments, are shared among all page translations.
1.1	30
14.2	31	= Understanding resources and representations =
1.1	32
10.4	33	"An important concept in REST is the existence of resources (sources of specific information), each of which is referenced with a global identifier (e.g., an URI in HTTP). In order to manipulate these resources, components of the network (user agents and origin servers) communicate via a standardized interface (e.g., HTTP) and exchange representations of these resources (the actual documents conveying the information)." ([[Wikipedia>>http://en.wikipedia.org/wiki/Representational_State_Transfer#REST.27s_central_principle:_resources]])
1.1	34
28.3	35	Resources in XWiki are pages, attachments, objects, properties, spaces, and all the //things// we described in the previous section. XWiki has a default way of conveying the information about these resources, i.e., by providing well defined XML representations that contain all the information associated to the resource in an XML format. This format is described using an XML Schema Definition file that can be found here: [[https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwiki-platform-rest/xwiki-platform-rest-model/src/main/resources/xwiki.rest.model.xsd]]
1.1	36
10.4	37	Of course the same resource can be represented in many different ways. This is yet to be documented.
1.1	38
10.4	39	Another important aspect of representations is that they contain useful information for linking related resources. This is a realization of the //Hypermedia As The Engine Of The Application State (HATEOAS)// principle. In XML representations this information is conveyed through the ##<link>## tag. This tag has two important parameters: rel and href. rel specifies the "semantics" of the link, while href is the URI of the linked resource.
9.2	40
1.1	41	For example, in the representation of a page, we can have links to the comments, tags, attachments which are independent resources associated to the current page. These links are provided in the XML representation of a page and allow a client to navigate to related resources... Like we do every day when we click on a link in a web page.

1.1	44
14.2	45	== Relations ==
1.1	46
5.1	47	The available relations that you might find in the XML resource representations are the following:
1.1	48
9.1	49	\|=Rel\|=Semantics
15.1	50	\|{{{http://www.xwiki.org/rel/wikis}}}\|The representation containing the list of virtual wikis.
	51	\|{{{http://www.xwiki.org/rel/spaces}}}\|The representation containing the list of spaces in a wiki.
	52	\|{{{http://www.xwiki.org/rel/pages}}}\|The representation containing the list of pages in a space.
	53	\|{{{http://www.xwiki.org/rel/translation}}}\|The representation containing a translation of a page.
	54	\|{{{http://www.xwiki.org/rel/page}}}\|The representation for a page.
	55	\|{{{http://www.xwiki.org/rel/space}}}\|The representation for a space.
	56	\|{{{http://www.xwiki.org/rel/parent}}}\|The representation for the page that is parent of the current resource.
	57	\|{{{http://www.xwiki.org/rel/home}}}\|The representation for the page that is the home of the current resource.
	58	\|{{{http://www.xwiki.org/rel/attachmentData}}}\|The representation of the actual attachment data.
	59	\|{{{http://www.xwiki.org/rel/comments}}}\|The representation of the list of comments associated to the current resource.
	60	\|{{{http://www.xwiki.org/rel/attachments}}}\|The representation of the list of attachments associated to the current resource.
	61	\|{{{http://www.xwiki.org/rel/objects}}}\|The representation of the list of objects associated to the current resource.
	62	\|{{{http://www.xwiki.org/rel/object}}}\|The representation for an object.
	63	\|{{{http://www.xwiki.org/rel/classes}}}\|The representation of the list of classes associated to the current resource.
	64	\|{{{http://www.xwiki.org/rel/history}}}\|The representation of the list of history information associated to the current resource.
	65	\|{{{http://www.xwiki.org/rel/class}}}\|The representation for a class.
	66	\|{{{http://www.xwiki.org/rel/property}}}\|The representation for a property.
	67	\|{{{http://www.xwiki.org/rel/properties}}}\|The representation of the list of properties associated to the current resource.
	68	\|{{{http://www.xwiki.org/rel/modifications}}}\|The representation of the list of modifications associated to the current resource.
	69	\|{{{http://www.xwiki.org/rel/children}}}\|The representation of the list of children associated to the current resource.
	70	\|{{{http://www.xwiki.org/rel/tags}}}\|The representation of the list of tags associated to the current resource.
	71	\|{{{http://www.xwiki.org/rel/tag}}}\|The representation of a tag.
	72	\|{{{http://www.xwiki.org/rel/search}}}\|The representation for a search resource.
9.2	73
8.3	74	Relations are defined as URIs in order to provide a sort of namespace. Currently these URIs are not links to real web pages but, in the future, they might point to descriptions of their semantics on actual web pages (or other kinds of representations).
1.1	75
14.2	76	== The "HATEOAS" Graph ==
1.1	77
20.1	78	In order to better understand the relations among resources you might have a look at this [[graph>>attach:XWikiHATEOAS.pdf]] that pictures all the resources available in the XWiki RESTful API and the relations among them. In this graph, nodes are [[URI templates>>http://bitworking.org/projects/URI-Templates/spec/draft-gregorio-uritemplate-03.txt]] representing classes of resources. Edges are the possible links that you might find in a representation of a given resource, and their associated relations.
9.2	79
1.1	80	This graph shows that by starting from the API entry-point a client can navigate and discover all the resources just by following the links provided in representations (and by knowing their semantics). This was exactly the way how this graph was generated.
	81
14.2	82	= Interacting with the XWiki RESTful API =
8.2	83
9.5	84	The XWiki RESTful API is accessible through HTTP so, in principle, you can use every client that is capable of "speaking" HTTP in order to interact with it. Even a web browser!
9.1	85	If you want to write more complex programs you might download an HTTP library for your favorite language (e.g., [[http://hc.apache.org/]]).
9.2	86
28.4	87	Java users might take advantage of the [[JAXB>>https://jaxb.dev.java.net]] framework and its [[XJC binding compiler>>https://jaxb.dev.java.net/jaxb20-ea3/docs/xjc.html]] in order to generate domain object models directly from the [[XML Schema Definition>>https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwiki-platform-rest/xwiki-platform-rest-model/src/main/resources/xwiki.rest.model.xsd]], and use them for serializing and de-serializing XML representations.
9.2	88
5.1	89	If you use this approach (Apache HTTP Client + JAXB) you will find yourself writing some code like this:
1.1	90
19.1	91	{{code language="java"}}
	92	import javax.xml.bind.JAXBContext;
	93	import javax.xml.bind.Unmarshaller;
	94
	95	import org.apache.commons.httpclient.HttpClient;
	96	import org.apache.commons.httpclient.methods.GetMethod;
	97	import org.xwiki.rest.model.jaxb.Page;
	98
	99	...
1.1	100	HttpClient httpClient = new HttpClient();
18.1	101	JAXBContext context = JAXBContext.newInstance("org.xwiki.rest.model.jaxb");
19.1	102	Unmarshaller unmarshaller = context.createUnmarshaller();
1.1	103
	104	GetMethod getMethod = new GetMethod("http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome");
	105	getMethod.addRequestHeader("Accept", "application/xml");
	106	httpClient.executeMethod(getMethod);
	107
	108	Page page = (Page) unmarshaller.unmarshal(getMethod.getResponseBodyAsStream());
9.1	109	{{/code}}
1.1	110
5.1	111	And you will have all the information about the Main.WebHome page in the Page object, without the need of handling XML directly.
9.2	112
9.1	113	Because of the wide variety of HTTP frameworks available we don't provide a full tutorial about using them. However, in order to show you how to interact with the XWiki RESTful API, we will use [[curl>>http://curl.haxx.se]]: a standard command line HTTP client that provides an interface to all the functionalities of the HTTP protocol.
9.2	114
5.1	115	By using curl, the previous example would have been:
1.1	116
19.1	117	{{code language="xml"}}
1.1	118	$ curl http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome
	119	<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
	120	<page xmlns="http://www.xwiki.org">
	121	<link rel="http://www.xwiki.org/rel/space" href="http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main"/>
	122	...
9.1	123	{{/code}}
1.1	124
14.2	125	== Authentication ==
1.1	126
5.1	127	The XWiki RESTful API supports two types of authentication:
1.1	128
9.1	129	* HTTP BASIC Auth: You provide your credentials using the Authorization HTTP header
	130	* XWiki session: If you are logged in XWiki and you use the cookies provided by the authentication mechanism, you will also be authenticated to the XWiki RESTful API. This is useful, for example, when you are interacting with the API using the XMLHttpRequest object of a browser using Javascript.
9.2	131
5.1	132	If you don't provide any credentials the XWiki RESTful API will recognize you as a XWiki.Guest user.
9.2	133
5.1	134	So if you have, let's say a Main.PrivatePage, and you try to do:
1.1	135
10.6	136	{{code language="none"}}
1.1	137	$ curl -v http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/PrivatePage
	138	...
	139	< HTTP/1.1 401 Unauthorized
	140	...
9.1	141	{{/code}}
1.1	142
9.3	143	You will get an Unauthorized empty response.
9.2	144
1.1	145	On the contrary, by specifying Admin credentials you gain access to the actual page:
	146
19.1	147	{{code language="xml"}}
1.1	148	$ curl -u Admin:admin http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/PrivatePage
	149	<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
	150	<page xmlns="http://www.xwiki.org">
	151	<link rel="http://www.xwiki.org/rel/space" href="http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main"/>
	152	...
	153	<content>Only admin can see this</content>
	154	</page>
9.1	155	{{/code}}
1.1	156
14.2	157	== Sending representations ==
1.1	158
	159	Many resources are modifiable, so you can send representations in order to change the state of those resources (e.g., pages).
28.4	160	All modifiable resources accept XML representations that conform to the [[XML Schema Definition>>https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwiki-platform-rest/xwiki-platform-rest-model/src/main/resources/xwiki.rest.model.xsd]]. However, some other representations might be accepted as well (see the following sections).
9.2	161
1.1	162	Resource update is usually done by using the PUT method, while resource creation is done via PUT or POST.
9.2	163
1.1	164	For example, in order to create a page you might do the following:
	165
19.1	166	{{code language="xml"}}
20.2	167	$ curl -u Admin:admin -X PUT --data-binary "@newpage.xml" -H "Content-Type: application/xml" http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/NewPage
1.1	168	<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
	169	<page xmlns="http://www.xwiki.org">
	170	<link rel="http://www.xwiki.org/rel/space" href="http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main"/>
	171	...
	172	<version>1.1</version>
	173	<majorVersion>1</majorVersion>
	174	<minorVersion>1</minorVersion>
	175	<created>2009-03-21+01:00</created>
	176	<creator>XWiki.Admin</creator>
	177	<modified>2009-03-21+01:00</modified>
	178	<modifier>XWiki.Admin</modifier>
	179	<content>This is a new page</content>
	180	</page>
9.1	181	{{/code}}
1.1	182
	183	Where newpage.xml is an XML file containing
	184
19.1	185	{{code language="xml"}}
1.1	186	<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
	187	<page xmlns="http://www.xwiki.org">
	188	<title>Hello world</title>
	189	<content>This is a new page</content>
	190	</page>
9.1	191	{{/code}}
1.1	192
	193	The page has been created and is accessible. Subsequent PUT requests to the page URI will modify its content.
	194
14.2	195	== Overcoming browser limitations ==
1.1	196
10.4	197	As said before, it could be useful to send information by using browser's XmlHttpRequest objects. However, currently many browsers only support GET and POST methods, so it is impossible to send, for example, PUT requests. In order to overcome this limitation you can override the HTTP Method by specifying a ##method## parameter in the URI query string.
9.2	198
10.4	199	In the previous example, if you send a POST request to the ##[[http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/NewPage?method=PUT]]## it will be interpreted as if it were an actual PUT request.
1.1	200
	201	This overriding mechanism allows the interaction with the XWiki RESTful API by using any kind of browser.
	202
14.2	203	== PUT vs POST ==
1.1	204
10.4	205	In the following sections you will see that sometimes resources are created by using PUT and sometimes by using POST. The general principle is that if the client is responsible for choosing the resource URI then PUT is used. If it's the server that bears this responsibility, then POST is used.
1.1	206
10.4	207	To be clearer, when a client wants to create a page it knows where that page should go, so it is able to communicate the server the target URI. PUT is used.
1.1	208
9.5	209	A client, on the contrary, cannot know beforehand what will be the URI of a comment, since comment URIs contains the ID of the comment and this information is generated by the server. In this case the client will do a POST and the server, in response, will communicate the URI it generated for the newly created comment.
1.1	210
14.2	211	= XWiki RESTful API Documentation =
8.4	212
9.5	213	In this section you will find the documentation of the whole XWiki RESTful API.
1.1	214
28.4	215	application/xml representations refers to the XML Schema Definition at the following location: [[https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwiki-platform-rest/xwiki-platform-rest-model/src/main/resources/xwiki.rest.model.xsd]]
1.1	216
9.1	217	Resource URIs are specified using [[URI templates>>http://bitworking.org/projects/URI-Templates/spec/draft-gregorio-uritemplate-03.txt]]. Bracketed elements are formal parameters and should be instantiated to actual values in order to retrieve the associated resource.
1.1	218
14.2	219	== Root resources ==
1.1	220
20.1	221	By defaut all the resources of the RESTful API are rooted at the following URI: ##http:~/~/server:port/xwiki/rest/## (depending on where your XWiki is running)
