+ * + * At first it might not be obvious why this extra complexity is worth the trouble. The payoff + * comes in the way of + * [guarantees that promise and deferred APIs make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md). + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * + * # The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * # The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved + * or rejected calls one of the success or error callbacks asynchronously as soon as the result + * is available. The callbacks are called with a single argument the result or rejection reason. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback` or `errorCallback`. + * + * + * # Chaining promises + * + * Because calling `then` api of a promise returns a new derived promise, it is easily possible + * to create a chain of promises: + * + *
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and its value will be
+ *   // the result of promiseA incremented by 1
+ * 
+ * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful apis like + * $http's response interceptors. + * + * + * # Differences between Kris Kowal's Q and $q + * + * There are three main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in angular, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - $q promises are recognized by the templating engine in angular, which means that in templates + * you can treat promises attached to a scope as if they were the resulting values. + * - Q has many more features that $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * # Testing + * + *
+ *    it('should simulate promise', inject(function($q, $rootScope) {

While for simple usage patters this doesn't matter much, for advanced usage, + * it is important to familiarize yourself with these apis and guarantees they provide. + * + * + * # General usage + * The `$http` service is a function which takes a single argument — a configuration object — + * that is used to generate an http request and returns a {@link ng.$q promise} + * with two $http specific methods: `success` and `error`. + * + *
+     *   $http({method: 'GET', url: '/someUrl'}).
+     *     success(function(data, status, headers, config) {
+     *       // this callback will be called asynchronously

+     *       // called asynchronously if an error occurs
+     *       // or server returns response with an error status.
+     *     });
+     * 
+ * + * Since the returned value of calling the $http function is a Promise object, you can also use + * the `then` method to register callbacks, and these callbacks will receive a single argument – + * an object representing the response. See the api signature and type info below for more + * details. + * + * A response status code that falls in the [200, 300) range is considered a success status and + * will result in the success callback being called. Note that if the response is a redirect, + * XMLHttpRequest will transparently follow it, meaning that the error callback will not be + * called for such responses. + * + * # Shortcut methods + * + * Since all invocation of the $http service require definition of the http method and url and + * POST and PUT requests require response body/data to be provided as well, shortcut methods + * were created to simplify using the api: + * + *
+     *   $http.get('/someUrl').success(successCallback);
+     *   $http.post('/someUrl', data).success(successCallback);
+     * 
+ * + * Complete list of shortcut methods: + * + * - {@link ng.$http#get $http.get} + * - {@link ng.$http#head $http.head} + * - {@link ng.$http#post $http.post} + * - {@link ng.$http#put $http.put} + * - {@link ng.$http#delete $http.delete} + * - {@link ng.$http#jsonp $http.jsonp} + * + * + * # Setting HTTP Headers + * + * The $http service will automatically add certain http headers to all requests. These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - `Accept: application/json, text/plain, * / *` + * - `X-Requested-With: XMLHttpRequest` + * - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from this configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with name equal to the lower-cased http method name, e.g. + * `$httpProvider.defaults.headers.get['My-Header']='value'`. + * + * Additionally, the defaults can be set at runtime via the `$http.defaults` object in a similar + * fassion as described above. + * + * + * # Transforming Requests and Responses + * + * Both requests and responses can be transformed using transform functions. By default, Angular + * applies these transformations: + * + * Request transformations: + * + * - if the `data` property of the request config object contains an object, serialize it into + * JSON format. + * + * Response transformations: + * + * - if XSRF prefix is detected, strip it (see Security Considerations section below) + * - if json response is detected, deserialize it using a JSON parser + * + * To globally augment or override the default transforms, modify the `$httpProvider.defaults.transformRequest` and + * `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`. These properties are by default an + * array of transform functions, which allows you to `push` or `unshift` a new transformation function into the + * transformation chain. You can also decide to completely override any default transformations by assigning your + * transformation functions to these properties directly without the array wrapper. + * + * Similarly, to locally override the request/response transforms, augment the `transformRequest` and/or + * `transformResponse` properties of the config object passed into `$http`. + * + * + * # Caching + * + * To enable caching set the configuration property `cache` to `true`. When the cache is + * enabled, `$http` stores the response from the server in local cache. Next time the + * response is served from the cache without sending a request to the server. + * + * Note that even if the response is served from cache, delivery of the data is asynchronous in + * the same way that real requests are. + * + * If there are multiple GET requests for the same url that should be cached using the same + * cache, but the cache is not populated yet, only one request to the server will be made and + * the remaining requests will be fulfilled using the response for the first request. + * + * + * # Response interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication or any kind of synchronous or + * asynchronous preprocessing of received responses, it is desirable to be able to intercept + * responses for http requests before they are handed over to the application code that + * initiated these requests. The response interceptors leverage the {@link ng.$q + * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing. + * + * The interceptors are service factories that are registered with the $httpProvider by + * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor — a function that + * takes a {@link ng.$q promise} and returns the original or a new promise. + * + *
+     *   // register the interceptor as a service
+     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+     *     return function(promise) {
+     *       return promise.then(function(response) {
+     *         // do something on success
+     *       }, function(response) {

+     *       });
+     *     }
+     *   });
+     *
+     *   $httpProvider.responseInterceptors.push('myHttpInterceptor');
+     *
+     *

+ * + * + * # Security Considerations + * + * When designing web applications, consider security threats from: + * + * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx + * JSON Vulnerability} + * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} + * + * Both server and the client must cooperate in order to eliminate these threats. Angular comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ## JSON Vulnerability Protection + * + * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx + * JSON Vulnerability} allows third party web-site to turn your JSON resource URL into + * {@link http://en.wikipedia.org/wiki/JSON#JSONP JSONP} request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * Angular will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + *
+     * ['one','two']
+     * 
+ * + * which is vulnerable to attack, your server can return: + *
+     * )]}',
+     * ['one','two']
+     * 
+ * + * Angular will strip the prefix, before processing the JSON. + * + * + * ## Cross Site Request Forgery (XSRF) Protection + * + * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which + * an unauthorized site can gain your user's private data. Angular provides following mechanism + * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie + * called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that + * runs on your domain could read the cookie, your server can be assured that the XHR came from + * JavaScript running on your domain. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET requests the + * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure + * that only JavaScript running on your domain could have read the token. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript making + * up its own tokens). We recommend that the token is a digest of your site's authentication + * cookie with {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}. + * + * + * @param {object} config Object describing the request to be made and how it should be + * processed. The object has following properties: + * + * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) + * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. + * - **params** – `{Object.}` – Map of strings or objects which will be turned to + * `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server. + * - **transformRequest** – `{function(data, headersGetter)|Array.}` – + * 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.}` – + * 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 $cacheFactory}, this cache will be used for + * caching. + * - **timeout** – `{number}` – timeout in milliseconds. + * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the + * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 + * requests with credentials} for more information. + * + * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the + * standard `then` method and two http specific methods: `success` and `error`. The `then` + * method takes two arguments a success and an error callback which will be called with a + * response object. The `success` and `error` methods take a single argument - a function that + * will be called when the request succeeds or fails respectively. The arguments passed into + * these functions are destructured representation of the response object passed into the + * `then` method. The response object has these properties: + * + * - **data** – `{string|Object}` – The response body transformed with the transform functions. + * - **status** – `{number}` – HTTP status code of the response. + * - **headers** – `{function([headerName])}` – Header getter function. + * - **config** – `{Object}` – The configuration object that was used to generate the request. + * + * @property {Array.} pendingRequests Array of config objects for currently pending + * requests. This is primarily meant to be used for debugging purposes. + * + * + * @example + + +

You configure ngPluralize directive + * by specifying the mappings between + * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html + * plural categories} and the strings to be displayed. + * + * # Plural categories and explicit number rules + * There are two + * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html + * plural categories} in Angular's default en-US locale: "one" and "other". + * + * While a pural category may match many numbers (for example, in en-US locale, "other" can match + * any number that is not 1), an explicit number rule can only match one number. For example, the + * explicit number rule for "3" matches the number 3. You will see the use of plural categories + * and explicit number rules throughout later parts of this documentation. + * + * # Configuring ngPluralize + * You configure ngPluralize by providing 2 attributes: `count` and `when`. + * You can also provide an optional attribute, `offset`. + * + * The value of the `count` attribute can be either a string or an {@link guide/expression + * Angular expression}; these are evaluated on the current scope for its bound value. + * + * The `when` attribute specifies the mappings between plural categories and the actual + * string to be displayed. The value of the attribute should be a JSON object so that Angular + * can interpret it correctly. + * + * The following example shows how to configure ngPluralize: + * + *
+ * 
+ * 
+ *
+ * + * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not + * specify this rule, 0 would be matched to the "other" category and "0 people are viewing" + * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for + * other numbers, for example 12, so that instead of showing "12 people are viewing", you can + * show "a dozen people are viewing". + * + * You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted + * into pluralized strings. In the previous example, Angular will replace `{}` with + * `{{personCount}}`. The closed braces `{}` is a placeholder + * for {{numberExpression}}. + * + * # Configuring ngPluralize with offset + * The `offset` attribute allows further customization of pluralized text, which can result in + * a better user experience. For example, instead of the message "4 people are viewing this document", + * you might display "John, Kate and 2 others are viewing this document". + * The offset attribute allows you to offset a number by any desired value. + * Let's take a look at an example: + * + *
+ * 
+ * 
+ * 
+ * + * Notice that we are still using two plural categories(one, other), but we added + * three explicit number rules 0, 1 and 2. + * When one person, perhaps John, views the document, "John is viewing" will be shown. + * When three people view the document, no explicit number rule is found, so + * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category. + * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing" + * is shown. + * + * Note that when you specify offsets, you must provide explicit number rules for + * numbers from 0 up to and including the offset. If you use an offset of 3, for example, + * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for + * plural categories "one" and "other". + * + * @param {string|expression} count The variable to be bounded to. + * @param {string} when The mapping between plural category to its correspoding strings. + * @param {number=} offset Offset to deduct from the total number. + * + * @example + + + +
+ Person 1:
+ Person 2:
+ Number of People:
+ + + Without Offset: + +
+ + + With Offset(2): + + +
