/**
* @ngdoc service
* @name $resource

* @requires $q
* @requires ng.$timeout
*
* @description
* A factory which creates a resource object that lets you interact with
* [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
*
* The returned resource object has action methods which provide high-level behaviors without
* the need to interact with the low level {@link ng.$http $http} service.
*
* Requires the {@link ngResource `ngResource`} module to be installed.
*
* By default, trailing slashes will be stripped from the calculated URLs,
* which can pose problems with server backends that do not expect that
* behavior. This can be disabled by configuring the `$resourceProvider` like
* this:
*
* ```js
app.config(['$resourceProvider', function($resourceProvider) {
// Don't strip trailing slashes from calculated URLs
$resourceProvider.defaults.stripTrailingSlashes = false;
}]);
* ```
*
* @param {string} url A parameterized URL template with parameters prefixed by `:` as in
* `/user/:username`. If you are using a URL with a port number (e.g.
* `http://example.com:8080/api`), it will be respected.
*
* If you are using a url with a suffix, just add the suffix, like this:
* `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
* or even `$resource('http://example.com/resource/:resource_id.:format')`
* If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
* collapsed down to a single `.`. If you need this sequence to appear and not collapse then you
* can escape it with `/\.`.
*
* @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
* `actions` methods. If a parameter value is a function, it will be called every time
* a param value needs to be obtained for a request (unless the param was overridden). The
* function will be passed the current data value as an argument.
*
* Each key value in the parameter object is first bound to url template if present and then any
* excess keys are appended to the url search query after the `?`.
*
* Given a template `/path/:verb` and parameter `{verb: 'greet', salutation: 'Hello'}` results in
* URL `/path/greet?salutation=Hello`.
*
* If the parameter value is prefixed with `@`, then the value for that parameter will be
* extracted from the corresponding property on the `data` object (provided when calling actions
* with a request body).
* For example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of
* `someParam` will be `data.someProp`.
* Note that the parameter will be ignored, when calling a "GET" action method (i.e. an action
* method that does not accept a request body).
*
* @param {Object.<Object>=} actions Hash with declaration of custom actions that will be available
* in addition to the default set of resource actions (see below). If a custom action has the same
* key as a default action (e.g. `save`), then the default action will be *overwritten*, and not
* extended.
*
* The declaration should be created in the format of {@link ng.$http#usage $http.config}: *
* {
* action1: {method:?, params:?, isArray:?, headers:?, ...},
* action2: {method:?, params:?, isArray:?, headers:?, ...},
* ...
* }
*
* Where:
*
* - **`action`** – {string} – The name of action. This name becomes the name of the method on
* your resource object.
* - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
* `DELETE`, `JSONP`, etc).
* - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
* the parameter value is a function, it will be called every time when a param value needs to
* be obtained for a request (unless the param was overridden). The function will be passed the
* current data value as an argument.
* - **`url`** – {string} – Action specific `url` override. The url templating is supported just
* like for the resource-level urls.
* - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
* see `returns` section.
* - **`transformRequest`** –
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
* Transform function or an array of such functions. The transform function takes the http
* request body and headers and returns its transformed (typically serialized) version.
* By default, transformRequest will contain one function that checks if the request data is
* an object and serializes it using `angular.toJson`. To prevent this behavior, set
* `transformRequest` to an empty array: `transformRequest: []`
* - **`transformResponse`** –
* `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
* Transform function or an array of such functions. The transform function takes the HTTP
* response body, headers and status and returns its transformed (typically deserialized)
* version.
* By default, transformResponse will contain one function that checks if the response looks
* like a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior,
* set `transformResponse` to an empty array: `transformResponse: []`
* - **`cache`** – `{boolean|Cache}` – A boolean value or object created with
* {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
* See {@link $http#caching $http Caching} for more information.
* - **`timeout`** – `{number}` – Timeout in milliseconds.<br />
* **Note:** In contrast to {@link ng.$http#usage $http.config}, {@link ng.$q promises} are
* **not** supported in `$resource`, because the same value would be used for multiple requests.
* If you are looking for a way to cancel requests, you should use the `cancellable` option.
* - **`cancellable`** – `{boolean}` – If true, the request made by a "non-instance" call will be
* cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
* value. Calling `$cancelRequest()` for a non-cancellable or an already completed/cancelled
* request will have no effect.
* - **`withCredentials`** – `{boolean}` – Whether to set the `withCredentials` flag on the
* XHR object. See
* [XMLHttpRequest.withCredentials](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials)
* for more information.
* - **`responseType`** – `{string}` – See
* [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/responseType).
* - **`interceptor`** – `{Object=}` – The interceptor object has four optional methods -
* `request`, `requestError`, `response`, and `responseError`. See
* {@link ng.$http#interceptors $http interceptors} for details. Note that
* `request`/`requestError` interceptors are applied before calling `$http`, thus before any
* global `$http` interceptors. Also, rejecting or throwing an error inside the `request`
* interceptor will result in calling the `responseError` interceptor.
* The resource instance or collection is available on the `resource` property of the
* `http response` object passed to `response`/`responseError` interceptors.
* Keep in mind that the associated promise will be resolved with the value returned by the
* response interceptors. Make sure you return an appropriate value and not the `response`
* object passed as input. For reference, the default `response` interceptor (which gets applied
* if you don't specify a custom one) returns `response.resource`.<br />
* See {@link ngResource.$resource#using-interceptors below} for an example of using
* interceptors in `$resource`.
* - **`hasBody`** – `{boolean}` – If true, then the request will have a body.
* If not specified, then only POST, PUT and PATCH requests will have a body. *
* @param {Object} options Hash with custom settings that should extend the * default `$resourceProvider` behavior. The supported options are:
*
* - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
* slashes from any calculated URL will be stripped. (Defaults to true.)
* - **`cancellable`** – {boolean} – If true, the request made by a "non-instance" call will be
* cancelled (if not already completed) by calling `$cancelRequest()` on the call's return value.
* This can be overwritten per action. (Defaults to false.)
*
* @returns {Object} A resource "class" object with methods for the default set of resource actions
* optionally extended with custom `actions`. The default set contains these actions:
* ```js
* {
* 'get': {method: 'GET'},
* 'save': {method: 'POST'},
* 'query': {method: 'GET', isArray: true},
* 'remove': {method: 'DELETE'},
* 'delete': {method: 'DELETE'}
* }
* ```
*
* Calling these methods invoke {@link ng.$http} with the specified http method, destination and
* parameters. When the data is returned from the server then the object is an instance of the
* resource class. The actions `save`, `remove` and `delete` are available on it as methods with
* the `$` prefix. This allows you to easily perform CRUD operations (create, read, update,
* delete) on server-side data like this:
* ```js
* var User = $resource('/user/:userId', {userId: '@id'});
* User.get({userId: 123}).$promise.then(function(user) {
* user.abc = true;
* user.$save();
* });
* ```
*
* It is important to realize that invoking a `$resource` object method immediately returns an
* empty reference (object or array depending on `isArray`). Once the data is returned from the
* server the existing reference is populated with the actual data. This is a useful trick since
* usually the resource is assigned to a model which is then rendered by the view. Having an empty
* object results in no rendering, once the data arrives from the server then the object is
* populated with the data and the view automatically re-renders itself showing the new data. This
* means that in most cases one never has to write a callback function for the action methods.
*
* The action methods on the class object or instance object can be invoked with the following
* parameters:
*
* - "class" actions without a body: `Resource.action([parameters], [success], [error])`
* - "class" actions with a body: `Resource.action([parameters], postData, [success], [error])`
* - instance actions: `instance.$action([parameters], [success], [error])`
*
*
* When calling instance methods, the instance itself is used as the request body (if the action
* should have a body). By default, only actions using `POST`, `PUT` or `PATCH` have request
* bodies, but you can use the `hasBody` configuration option to specify whether an action
* should have a body or not (regardless of its HTTP method).
*
*
* Success callback is called with (value (Object|Array), responseHeaders (Function),
* status (number), statusText (string)) arguments, where `value` is the populated resource
* instance or collection object. The error callback is called with (httpResponse) argument.
*
* Class actions return an empty instance (with the additional properties listed below).
* Instance actions return a promise for the operation.
*
* The Resource instances and collections have these additional properties:
*
* - `$promise`: The {@link ng.$q promise} of the original server interaction that created this
* instance or collection.
*
* On success, the promise is resolved with the same resource instance or collection object,
* updated with data from server. This makes it easy to use in the
* {@link ngRoute.$routeProvider `resolve` section of `$routeProvider.when()`} to defer view * rendering until the resource(s) are loaded.
*
* On failure, the promise is rejected with the {@link ng.$http http response} object.
*
* If an interceptor object was provided, the promise will instead be resolved with the value
* returned by the response interceptor (on success) or responceError interceptor (on failure).
*
* - `$resolved`: `true` after first server interaction is completed (either with success or
* rejection), `false` before that. Knowing if the Resource has been resolved is useful in
* data-binding. If there is a response/responseError interceptor and it returns a promise,
* `$resolved` will wait for that too.
*
* The Resource instances and collections have these additional methods:
*
* - `$cancelRequest`: If there is a cancellable, pending request related to the instance or
* collection, calling this method will abort the request.
*
* The Resource instances have these additional methods:
*
* - `toJSON`: It returns a simple object without any of the extra properties added as part of
* the Resource API. This object can be serialized through {@link angular.toJson} safely
* without attaching AngularJS-specific fields. Notice that `JSON.stringify` (and
* `angular.toJson`) automatically use this method when serializing a Resource instance
* (see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON%28%29_behavior)).
*
* @example
*
* ### Basic usage
*
```js
// Define a CreditCard class
var CreditCard = $resource('/users/:userId/cards/:cardId',
{userId: 123, cardId: '@id'}, {
charge: {method: 'POST', params: {charge: true}}
});
// We can retrieve a collection from the server
var cards = CreditCard.query();
// GET: /users/123/cards
// server returns: [{id: 456, number: '1234', name: 'Smith'}]
// Wait for the request to complete
cards.$promise.then(function() {
var card = cards[0];
// Each item is an instance of CreditCard
expect(card instanceof CreditCard).toEqual(true);
// Non-GET methods are mapped onto the instances
card.name = 'J. Smith';
card.$save();
// POST: /users/123/cards/456 {id: 456, number: '1234', name: 'J. Smith'}
// server returns: {id: 456, number: '1234', name: 'J. Smith'}
// Our custom method is mapped as well (since it uses POST)
card.$charge({amount: 9.99});
// POST: /users/123/cards/456?amount=9.99&charge=true {id: 456, number: '1234', name: 'J. Smith'}
});
// We can create an instance as well
var newCard = new CreditCard({number: '0123'});
newCard.name = 'Mike Smith';
var savePromise = newCard.$save();
// POST: /users/123/cards {number: '0123', name: 'Mike Smith'}
// server returns: {id: 789, number: '0123', name: 'Mike Smith'}
savePromise.then(function() {
// Once the promise is resolved, the created instance
// is populated with the data returned by the server expect(newCard.id).toEqual(789);
});
```
*
* The object returned from a call to `$resource` is a resource "class" which has one "static"
* method for each action in the definition.
*
* Calling these methods invokes `$http` on the `url` template with the given HTTP `method`,
* `params` and `headers`.
*
* @example
*
* ### Accessing the response
*
* When the data is returned from the server then the object is an instance of the resource type and
* all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
* operations (create, read, update, delete) on server-side data.
*
```js
var User = $resource('/users/:userId', {userId: '@id'});
User.get({userId: 123}).$promise.then(function(user) {
user.abc = true;
user.$save();
});
```
*
* It's worth noting that the success callback for `get`, `query` and other methods gets called with
* the resource instance (populated with the data that came from the server) as well as an `$http`
* header getter function, the HTTP status code and the response status text. So one could rewrite
* the above example and get access to HTTP headers as follows:
*
```js
var User = $resource('/users/:userId', {userId: '@id'});
User.get({userId: 123}, function(user, getResponseHeaders) {
user.abc = true;
user.$save(function(user, putResponseHeaders) {
// `user` => saved `User` object
// `putResponseHeaders` => `$http` header getter
});
});
```
*
* @example
*
* ### Creating custom actions
*
* In this example we create a custom method on our resource to make a PUT request:
*
```js
var app = angular.module('app', ['ngResource']);
// Some APIs expect a PUT request in the format URL/object/ID
// Here we are creating an 'update' method
app.factory('Notes', ['$resource', function($resource) {
return $resource('/notes/:id', {id: '@id'}, {
update: {method: 'PUT'}
});
}]);
// In our controller we get the ID from the URL using `$location`
app.controller('NotesCtrl', ['$location', 'Notes', function($location, Notes) {
// First, retrieve the corresponding `Note` object from the server
// (Assuming a URL of the form `.../notes?id=XYZ`)
var noteId = $location.search().id;
var note = Notes.get({id: noteId});
note.$promise.then(function() {
note.content = 'Hello, world!';
// Now call `update` to save the changes on the server Notes.update(note);
// This will PUT /notes/ID with the note object as the request payload
// Since `update` is a non-GET method, it will also be available on the instance
// (prefixed with `$`), so we could replace the `Note.update()` call with:
//note.$update();
});
}]);
```
*
* @example
*
* ### Cancelling requests
*
* If an action's configuration specifies that it is cancellable, you can cancel the request related
* to an instance or collection (as long as it is a result of a "non-instance" call):
*
```js
// ...defining the `Hotel` resource...
var Hotel = $resource('/api/hotels/:id', {id: '@id'}, {
// Let's make the `query()` method cancellable
query: {method: 'get', isArray: true, cancellable: true}
});
// ...somewhere in the PlanVacationController...
...
this.onDestinationChanged = function onDestinationChanged(destination) {
// We don't care about any pending request for hotels
// in a different destination any more
if (this.availableHotels) {
this.availableHotels.$cancelRequest();
}
// Let's query for hotels in `destination`
// (calls: /api/hotels?location=<destination>)
this.availableHotels = Hotel.query({location: destination});
};
```
*
* @example
*
* ### Using interceptors
*
* You can use interceptors to transform the request or response, perform additional operations, and
* modify the returned instance/collection. The following example, uses `request` and `response`
* interceptors to augment the returned instance with additional info:
*
```js
var Thing = $resource('/api/things/:id', {id: '@id'}, {
save: {
method: 'POST',
interceptor: {
request: function(config) {
// Before the request is sent out, store a timestamp on the request config
config.requestTimestamp = Date.now();
return config;
},
response: function(response) {
// Get the instance from the response object
var instance = response.resource;
// Augment the instance with a custom `saveLatency` property, computed as the time
// between sending the request and receiving the response.
instance.saveLatency = Date.now() - response.config.requestTimestamp;
// Return the instance
return instance;
}
}
} });
Thing.save({foo: 'bar'}).$promise.then(function(thing) {
console.log('That thing was saved in ' + thing.saveLatency + 'ms.');
});
```
*

/**
* @ngdoc property
* @name $resourceProvider#defaults
* @description
* Object containing default options used when creating `$resource` instances.
*
* The default values satisfy a wide range of usecases, but you may choose to overwrite any of
* them to further customize your instances. The available properties are:
*
* - **stripTrailingSlashes** – `{boolean}` – If true, then the trailing slashes from any
* calculated URL will be stripped.<br />
* (Defaults to true.)
* - **cancellable** – `{boolean}` – If true, the request made by a "non-instance" call will be
* cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
* value. For more details, see {@link ngResource.$resource}. This can be overwritten per
* resource class or action.<br />
* (Defaults to false.)
* - **actions** - `{Object.<Object>}` - A hash with default actions declarations. Actions are
* high-level methods corresponding to RESTful actions/methods on resources. An action may
* specify what HTTP method to use, what URL to hit, if the return value will be a single
* object or a collection (array) of objects etc. For more details, see
* {@link ngResource.$resource}. The actions can also be enhanced or overwritten per resource
* class.<br />
* The default actions are:
* ```js
* {
* get: {method: 'GET'},
* save: {method: 'POST'},
* query: {method: 'GET', isArray: true},
* remove: {method: 'DELETE'},
* delete: {method: 'DELETE'}
* }
* ```
*
* #### Example
*
* For example, you can specify a new `update` action that uses the `PUT` HTTP verb:
*
* ```js
* angular.
* module('myApp').
* config(['$resourceProvider', function ($resourceProvider) {
* $resourceProvider.defaults.actions.update = {
* method: 'PUT'
* };
* }]);
* ```
*
* Or you can even overwrite the whole `actions` list and specify your own:
*
* ```js
* angular.
* module('myApp').
* config(['$resourceProvider', function ($resourceProvider) {
* $resourceProvider.defaults.actions = { * create: {method: 'POST'},
* get: {method: 'GET'},
* getAll: {method: 'GET', isArray:true},
* update: {method: 'PUT'},
* delete: {method: 'DELETE'}
* };
* });
* ```
