67/**
68 * @ngdoc service
69 * @name $resource
70 * @requires $http
71 *
72 * @description
73 * A factory which creates a resource object that lets you interact with
74 * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
75 *
76 * The returned resource object has action methods which provide high-level behaviors without
77 * the need to interact with the low level {@link ng.$http $http} service.
78 *
79 * Requires the {@link ngResource `ngResource`} module to be installed.
80 *
81 * By default, trailing slashes will be stripped from the calculated URLs,
82 * which can pose problems with server backends that do not expect that
83 * behavior. This can be disabled by configuring the `$resourceProvider` like
84 * this:
85 *
86 * ```js
87 app.config(['$resourceProvider', function($resourceProvider) {
88 // Don't strip trailing slashes from calculated URLs
89 $resourceProvider.defaults.stripTrailingSlashes = false;
90 }]);
91 * ```
92 *
93 * @param {string} url A parametrized URL template with parameters prefixed by `:` as in
94 * `/user/:username`. If you are using a URL with a port number (e.g.
95 * `http://example.com:8080/api`), it will be respected.
96 *
97 * If you are using a url with a suffix, just add the suffix, like this:
98 * `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
99 * or even `$resource('http://example.com/resource/:resource_id.:format')`
100 * If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
101 * collapsed down to a single `.`. If you need this sequence to appear and not collapse then you
102 * can escape it with `/\.`.
103 *
104 * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
105 * `actions` methods. If any of the parameter value is a function, it will be executed every time
106 * when a param value needs to be obtained for a request (unless the param was overridden).
107 *
108 * Each key value in the parameter object is first bound to url template if present and then any
109 * excess keys are appended to the url search query after the `?`.
110 *
111 * Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
112 * URL `/path/greet?salutation=Hello`.
113 *
114 * If the parameter value is prefixed with `@` then the value for that parameter will be extracted
115 * from the corresponding property on the `data` object (provided when calling an action method). For
116 * example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of `someParam`
117 * will be `data.someProp`.
118 *
119 * @param {Object.<Object>=} actions Hash with declaration of custom action that should extend
120 * the default set of resource actions. The declaration should be created in the format of {@link
121 * ng.$http#usage $http.config}:
122 *
123 * {action1: {method:?, params:?, isArray:?, headers:?, ...},
124 * action2: {method:?, params:?, isArray:?, headers:?, ...},
125 * ...}
126 *
127 * Where:
128 *
129 * - **`action`** – {string} – The name of action. This name becomes the name of the method on
130 * your resource object.
131 * - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
132 * `DELETE`, `JSONP`, etc).
133 * - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
134 * the parameter value is a function, it will be executed every time when a param value needs to
135 * be obtained for a request (unless the param was overridden).
136 * - **`url`** – {string} – action specific `url` override. The url templating is supported just
137 * like for the resource-level urls.
138 * - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
139 * see `returns` section.
140 * - **`transformRequest`** –
141 * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
142 * transform function or an array of such functions. The transform function takes the http
143 * request body and headers and returns its transformed (typically serialized) version.
144 * By default, transformRequest will contain one function that checks if the request data is
145 * an object and serializes to using `angular.toJson`. To prevent this behavior, set
146 * `transformRequest` to an empty array: `transformRequest: []`
147 * - **`transformResponse`** –
148 * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
149 * transform function or an array of such functions. The transform function takes the http
150 * response body and headers and returns its transformed (typically deserialized) version.
151 * By default, transformResponse will contain one function that checks if the response looks like
152 * a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior, set
153 * `transformResponse` to an empty array: `transformResponse: []`
154 * - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
155 * GET request, otherwise if a cache instance built with
156 * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
157 * caching.
158 * - **`timeout`** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} that
159 * should abort the request when resolved.
160 * - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
161 * XHR object. See
162 * [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5)
163 * for more information.
164 * - **`responseType`** - `{string}` - see
165 * [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
166 * - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
167 * `response` and `responseError`. Both `response` and `responseError` interceptors get called
168 * with `http response` object. See {@link ng.$http $http interceptors}.
169 *
170 * @param {Object} options Hash with custom settings that should extend the
171 * default `$resourceProvider` behavior. The only supported option is
172 *
173 * Where:
174 *
175 * - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
176 * slashes from any calculated URL will be stripped. (Defaults to true.)
177 *
178 * @returns {Object} A resource "class" object with methods for the default set of resource actions
179 * optionally extended with custom `actions`. The default set contains these actions:
180 * ```js
181 * { 'get': {method:'GET'},
182 * 'save': {method:'POST'},
183 * 'query': {method:'GET', isArray:true},
184 * 'remove': {method:'DELETE'},
185 * 'delete': {method:'DELETE'} };
186 * ```
187 *
188 * Calling these methods invoke an {@link ng.$http} with the specified http method,
189 * destination and parameters. When the data is returned from the server then the object is an
190 * instance of the resource class. The actions `save`, `remove` and `delete` are available on it
191 * as methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
192 * read, update, delete) on server-side data like this:
193 * ```js
194 * var User = $resource('/user/:userId', {userId:'@id'});
195 * var user = User.get({userId:123}, function() {
196 * user.abc = true;
197 * user.$save();
198 * });
199 * ```
200 *
201 * It is important to realize that invoking a $resource object method immediately returns an
202 * empty reference (object or array depending on `isArray`). Once the data is returned from the
203 * server the existing reference is populated with the actual data. This is a useful trick since
204 * usually the resource is assigned to a model which is then rendered by the view. Having an empty
205 * object results in no rendering, once the data arrives from the server then the object is
206 * populated with the data and the view automatically re-renders itself showing the new data. This
207 * means that in most cases one never has to write a callback function for the action methods.
208 *
209 * The action methods on the class object or instance object can be invoked with the following
210 * parameters:
211 *
212 * - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
213 * - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
214 * - non-GET instance actions: `instance.$action([parameters], [success], [error])`
215 *
216 * Success callback is called with (value, responseHeaders) arguments. Error callback is called
217 * with (httpResponse) argument.
218 *
219 * Class actions return empty instance (with additional properties below).
220 * Instance actions return promise of the action.
221 *
222 * The Resource instances and collection have these additional properties:
223 *
224 * - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
225 * instance or collection.
226 *
227 * On success, the promise is resolved with the same resource instance or collection object,
228 * updated with data from server. This makes it easy to use in
229 * {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
230 * rendering until the resource(s) are loaded.
231 *
232 * On failure, the promise is resolved with the {@link ng.$http http response} object, without
233 * the `resource` property.
234 *
235 * If an interceptor object was provided, the promise will instead be resolved with the value
236 * returned by the interceptor.
237 *
238 * - `$resolved`: `true` after first server interaction is completed (either with success or
239 * rejection), `false` before that. Knowing if the Resource has been resolved is useful in
240 * data-binding.
241 *
242 * @example
243 *
244 * # Credit card resource
245 *
246 * ```js
247 // Define CreditCard class
248 var CreditCard = $resource('/user/:userId/card/:cardId',
249 {userId:123, cardId:'@id'}, {
250 charge: {method:'POST', params:{charge:true}}
251 });
252
253 // We can retrieve a collection from the server
254 var cards = CreditCard.query(function() {
255 // GET: /user/123/card
256 // server returns: [ {id:456, number:'1234', name:'Smith'} ];
257
258 var card = cards[0];
259 // each item is an instance of CreditCard
260 expect(card instanceof CreditCard).toEqual(true);
261 card.name = "J. Smith";
262 // non GET methods are mapped onto the instances
263 card.$save();
264 // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
265 // server returns: {id:456, number:'1234', name: 'J. Smith'};
266
267 // our custom method is mapped as well.
268 card.$charge({amount:9.99});
269 // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
270 });
271
272 // we can create an instance as well
273 var newCard = new CreditCard({number:'0123'});
274 newCard.name = "Mike Smith";
275 newCard.$save();
276 // POST: /user/123/card {number:'0123', name:'Mike Smith'}
277 // server returns: {id:789, number:'0123', name: 'Mike Smith'};
278 expect(newCard.id).toEqual(789);
279 * ```
280 *
281 * The object returned from this function execution is a resource "class" which has "static" method
282 * for each action in the definition.
283 *
284 * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
285 * `headers`.
286 * When the data is returned from the server then the object is an instance of the resource type and
287 * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
288 * operations (create, read, update, delete) on server-side data.
289
290 ```js
291 var User = $resource('/user/:userId', {userId:'@id'});
292 User.get({userId:123}, function(user) {
293 user.abc = true;
294 user.$save();
295 });
296 ```
297 *
298 * It's worth noting that the success callback for `get`, `query` and other methods gets passed
299 * in the response that came from the server as well as $http header getter function, so one
300 * could rewrite the above example and get access to http headers as:
301 *
302 ```js
303 var User = $resource('/user/:userId', {userId:'@id'});
304 User.get({userId:123}, function(u, getResponseHeaders){
305 u.abc = true;
306 u.$save(function(u, putResponseHeaders) {
307 //u => saved user object
308 //putResponseHeaders => $http header getter
309 });
310 });
311 ```
312 *
313 * You can also access the raw `$http` promise via the `$promise` property on the object returned
314 *
315 ```
316 var User = $resource('/user/:userId', {userId:'@id'});
317 User.get({userId:123})
318 .$promise.then(function(user) {
319 $scope.user = user;
320 });
321 ```
322
323 * # Creating a custom 'PUT' request
324 * In this example we create a custom method on our resource to make a PUT request
325 * ```js
326 * var app = angular.module('app', ['ngResource', 'ngRoute']);
327 *
328 * // Some APIs expect a PUT request in the format URL/object/ID
329 * // Here we are creating an 'update' method
330 * app.factory('Notes', ['$resource', function($resource) {
331 * return $resource('/notes/:id', null,
332 * {
333 * 'update': { method:'PUT' }
334 * });
335 * }]);
336 *
337 * // In our controller we get the ID from the URL using ngRoute and $routeParams
338 * // We pass in $routeParams and our Notes factory along with $scope
339 * app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
340 function($scope, $routeParams, Notes) {
341 * // First get a note object from the factory
342 * var note = Notes.get({ id:$routeParams.id });
343 * $id = note.id;
344 *
345 * // Now call update passing in the ID first then the object you are updating
346 * Notes.update({ id:$id }, note);
347 *
348 * // This will PUT /notes/ID with the note object in the request payload
349 * }]);
