|
|
* 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 $http} service.
|
|||
|
|
*
|
|||
|
|
* Requires the {@link ngResource `ngResource`} module to be installed.
|
|||
|
|
*
|
|||
|
|
* @param {string} url A parametrized URL template with parameters prefixed by `:` as in
|
|||
|
|
* `/user/:username`. If you are using a URL with a port number (e.g.
|
|||
|
|
* `http://example.com:8080/api`), it will be respected.
|
|||
|
|
*
|
|||
|
|
* If you are using a url with a suffix, just add the suffix, like this:
|
|||
|
|
* `$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 any of the parameter value is a function, it will be executed every time
|
|||
|
|
* when a param value needs to be obtained for a request (unless the param was overridden).
|
|||
|
|
*
|
|||
|
|
* 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 of that parameter is extracted from
|
|||
|
|
* the data object (useful for non-GET operations).
|
|||
|
|
*
|
|||
|
|
* @param {Object.<Object>=} actions Hash with declaration of custom action that should extend the
|
|||
|
|
* default set of resource actions. The declaration should be created in the format of {@link
|
|||
|
|
* ng.$http#Parameters $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} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`, `DELETE`,
|
|||
|
|
* and `JSONP`.
|
|||
|
|
* - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of the
|
|||
|
|
* parameter value is a function, it will be executed every time when a param value needs to be
|
|||
|
|
* obtained for a request (unless the param was overridden).
|
|||
|
|
* - **`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.
|
|||
|
|
* - **`transformResponse`** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
|
|||
|
|
* transform function or an array of such functions. The transform function takes the http
|
|||
|
|
* response body and headers and returns its transformed (typically deserialized) version.
|
|||
|
|
* - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
|
|||
|
|
* GET request, otherwise if a cache instance built with
|
|||
|
|
* {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
|
|||
|
|
* caching.
|
|||
|
|
* - **`timeout`** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} that
|
|||
|
|
* should abort the request when resolved.
|
|||
|
|
* - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
|
|||
|
|
* XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
|
|||
|
|
* requests with credentials} for more information.
|
|||
|
|
* - **`responseType`** - `{string}` - see {@link
|
|||
|
|
* https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}.
|
|||
|
|
* - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
|
|||
|
|
* `response` and `responseError`. Both `response` and `responseError` interceptors get called
|
|||
|
|
* with `http response` object. See {@link ng.$http $http interceptors}.
|
|||
|
|
*
|
|||
|
|
* @returns {Object} A resource "class" object with methods for the default set of resource actions
|
|||
|
|
* optionally extended with custom `actions`. The default set contains these actions:
|
|||
|
|
*
|
|||
|
|
* { 'get': {method:'GET'},
|
|||
|
|
* 'save': {method:'POST'},
|
|||
|
|
* 'query': {method:'GET', isArray:true},
|
|||
|
|
* 'remove': {method:'DELETE'},
|
|||
|
|
* 'delete': {method:'DELETE'} };
|
|||
|
|
*
|
|||
|
|
* Calling these methods invoke an {@link ng.$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:
|
|||
|
|
* <pre>
|
|||
|
|
var User = $resource('/user/:userId', {userId:'@id'});
|
|||
|
|
var user = User.get({userId:123}, function() {
|
|||
|
|
user.abc = true;
|
|||
|
|
user.$save();
|
|||
|
|
});
|
|||
|
|
</pre>
|
|||
|
|
*
|
|||
|
|
* It is important to realize that invoking a $resource object method immediately returns an
|
|||
|
|
* empty reference (object or array depending on `isArray`). Once the data is returned from the
|
|||
|
|
* server the existing reference is populated with the actual data. This is a useful trick since
|
|||
|
|
* usually the resource is assigned to a model which is then rendered by the view. Having an empty
|
|||
|
|
* object results in no rendering, once the data arrives from the server then the object is
|
|||
|
|
* populated with the data and the view automatically re-renders itself showing the new data. This
|
|||
|
|
* means that in most case one never has to write a callback function for the action methods.
|
|||
|
|
*
|
|||
|
|
* The action methods on the class object or instance object can be invoked with the following
|
|||
|
|
* parameters:
|
|||
|
|
*
|
|||
|
|
* - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
|
|||
|
|
* - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
|
|||
|
|
* - non-GET instance actions: `instance.$action([parameters], [success], [error])`
|
|||
|
|
*
|
|||
|
|
* Success callback is called with (value, responseHeaders) arguments. Error callback is called
|
|||
|
|
* with (httpResponse) argument.
|
|||
|
|
*
|
|||
|
|
* Class actions return empty instance (with additional properties below).
|
|||
|
|
* Instance actions return promise of the action.
|
|||
|
|
*
|
|||
|
|
* The Resource instances and collection 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
|
|||
|
|
* {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view rendering
|
|||
|
|
* until the resource(s) are loaded.
|
|||
|
|
*
|
|||
|
|
* On failure, the promise is resolved with the {@link ng.$http http response} object,
|
|||
|
|
* without the `resource` property.
|
|||
|
|
*
|
|||
|
|
* - `$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.
|
|||
|
|
*

|
|||
|
|

// Define CreditCard class

var CreditCard = $resource('/user/:userId/card/:cardId',
|

|
|
{userId:123, cardId:'@id'}, {
|

charge: {method:'POST', params:{charge:true}}

|
|
expect(card instanceof CreditCard).toEqual(true);
|
|||
|
|
card.name = "J. Smith";
|

|
|
// non GET methods are mapped onto the instances
|

|
|
card.$save();

|

});
|

var newCard = new CreditCard({number:'0123'});

|

|
|
* </pre>
|
|||
|
|
*
|
|||
|
|
* The object returned from this function execution is a resource "class" which has "static" method
|
|||
|
|
* for each action in the definition.
|
|||
|
|
*
|
|||
|
|
* Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and `headers`.
|
|||
|
|
* When the data is returned from the server then the object is an instance of the resource type and
|
|||
|
|
* all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
|
|||
|
|
* operations (create, read, update, delete) on server-side data.
