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 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 for that parameter will be extracted * from the corresponding property on the `data` object (provided when calling an action method). For * example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of `someParam` * will be `data.someProp`. * * @param {Object.<Object>=} actions Hash with declaration of custom actions that should extend * the default set of resource actions. 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 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. * By default, transformRequest will contain one function that checks if the request data is * an object and serializes to using `angular.toJson`. To prevent this behavior, set * `transformRequest` to an empty array: `transformRequest: []` * - **`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. * 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}` ? 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 * [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5) * for more information. * - **`responseType`** - `{string}` - see * [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType). * - **`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 $http interceptors}. * * @param {Object} options Hash with custom settings that should extend the * default `$resourceProvider` behavior. The only supported option is * * Where: * * - **`stripTrailingSlashes`** ? {boolean} ? If true then the trailing * slashes from any calculated URL will be stripped. (Defaults to true.) * * @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 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: * ```js * var User = $resource('/user/:userId', {userId:'@id'}); * var user = User.get({userId:123}, function() { * user.abc = true; * user.$save(); * }); * ``` * * It is important to realize that invoking a $resource object method immediately returns an * empty reference (object or array depending on `isArray`). Once the data is returned from the * server the existing reference is populated with the actual data. This is a useful trick since * usually the resource is assigned to a model which is then rendered by the view. Having an empty * object results in no rendering, once the data arrives from the server then the object is * populated with the data and the view automatically re-renders itself showing the new data. This * means that in most cases one never has to write a callback function for the action methods. * * The action methods on the class object or instance object can be invoked with the following * parameters: * * - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])` * - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])` * - non-GET instance actions: `instance.$action([parameters], [success], [error])` * * * Success callback is called with (value, responseHeaders) arguments, where the value is * the populated resource instance or collection object. The 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. * * If an interceptor object was provided, the promise will instead be resolved with the value * returned by the interceptor. * * - `$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. * * @example * * # Credit card resource * * ```js // Define CreditCard class var CreditCard = $resource('/user/:userId/card/:cardId', {userId:123, cardId:'@id'}, { charge: {method:'POST', params:{charge:true}} }); // We can retrieve a collection from the server var cards = CreditCard.query(function() { // GET: /user/123/card // server returns: [ {id:456, number:'1234', name:'Smith'} ]; var card = cards[0]; // each item is an instance of CreditCard expect(card instanceof CreditCard).toEqual(true); card.name = "J. Smith"; // non GET methods are mapped onto the instances card.$save(); // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'} // server returns: {id:456, number:'1234', name: 'J. Smith'}; // our custom method is mapped as well. card.$charge({amount:9.99}); // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'} }); // we can create an instance as well var newCard = new CreditCard({number:'0123'}); newCard.name = "Mike Smith"; newCard.$save(); // POST: /user/123/card {number:'0123', name:'Mike Smith'} // server returns: {id:789, number:'0123', name: 'Mike Smith'}; expect(newCard.id).toEqual(789); * ``` * * 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. ```js var User = $resource('/user/:userId', {userId:'@id'}); User.get({userId:123}, function(user) { user.abc = true; user.$save(); }); ``` * * It's worth noting that the success callback for `get`, `query` and other methods gets passed * in the response that came from the server as well as $http header getter function, so one * could rewrite the above example and get access to http headers as: * ```js var User = $resource('/user/:userId', {userId:'@id'}); User.get({userId:123}, function(u, getResponseHeaders){ u.abc = true; u.$save(function(u, putResponseHeaders) { //u => saved user object //putResponseHeaders => $http header getter }); }); ``` * * You can also access the raw `$http` promise via the `$promise` property on the object returned * ``` var User = $resource('/user/:userId', {userId:'@id'}); User.get({userId:123}) .$promise.then(function(user) { $scope.user = user; }); ``` * # Creating a custom 'PUT' request * In this example we create a custom method on our resource to make a PUT request * ```js * var app = angular.module('app', ['ngResource', 'ngRoute']); * * // Some APIs expect a PUT request in the format URL/object/ID * // Here we are creating an 'update' method * app.factory('Notes', ['$resource', function($resource) { * return $resource('/notes/:id', null, * { * 'update': { method:'PUT' } * }); * }]); * * // In our controller we get the ID from the URL using ngRoute and $routeParams * // We pass in $routeParams and our Notes factory along with $scope * app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes', function($scope, $routeParams, Notes) { * // First get a note object from the factory * var note = Notes.get({ id:$routeParams.id }); * $id = note.id; * * // Now call update passing in the ID first then the object you are updating * Notes.update({ id:$id }, note); * * // This will PUT /notes/ID with the note object in the request payload * }]); * ``` */ angular.module('ngResource', ['ng']). provider('$resource', function() { var provider = this; this.defaults = { // Strip slashes by default stripTrailingSlashes: true, // Default actions configuration actions: { 'get': {method: 'GET'}, 'save': {method: 'POST'}, 'query': {method: 'GET', isArray: true}, 'remove': {method: 'DELETE'}, 'delete': {method: 'DELETE'} } }; this.$get = ['$http', '$q', function($http, $q) { var noop = angular.noop, forEach = angular.forEach, extend = angular.extend, copy = angular.copy, isFunction = angular.isFunction; /** * We need our custom method because encodeURIComponent is too aggressive and doesn't follow * http://www.ietf.org/rfc/rfc3986.txt with regards to the character set * (pchar) allowed in path segments: * segment = *pchar * pchar = unreserved / pct-encoded / sub-delims / ":" / "@" * pct-encoded = "%" HEXDIG HEXDIG * unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~" * sub-delims = "!" / "$" / "&" / "'" / "(" / ")" * / "*" / "+" / "," / ";" / "=" */ function encodeUriSegment(val) { return encodeUriQuery(val, true). replace(/%26/gi, '&'). replace(/%3D/gi, '='). replace(/%2B/gi, '+'); } /** * This method is intended for encoding *key* or *value* parts of query component.
