*
* @description
* The `$http` service is a core Angular service that facilitates communication with the remote
* HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
* object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
*
* For unit testing applications that use `$http` service, see
* {@link ngMock.$httpBackend $httpBackend mock}.
*
* For a higher level of abstraction, please check out the {@link ngResource.$resource
* $resource} service.
*
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
* the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
* it is important to familiarize yourself with these APIs and the guarantees they provide.
*
*
* ## General usage
* The `$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`.
*
* ```js
* // Simple GET request example :
* $http.get('/someUrl').
* success(function(data, status, headers, config) {
* // this callback will be called asynchronously
* // when the response is available
* }).
* error(function(data, status, headers, config) {
* // called asynchronously if an error occurs
* // or server returns response with an error status.
* });
* ```
*
* ```js
* // Simple POST request example (passing data) :
* $http.post('/someUrl', {msg:'hello word!'}).
* success(function(data, status, headers, config) {
* // this callback will be called asynchronously
* // when the response is available
* }).
* error(function(data, status, headers, config) {
* // 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`, 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 between 200 and 299 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.
*
* ## Writing Unit Tests that use $http
* When unit testing (using {@link ngMock ngMock}), it is necessary to call
* {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
* request using trained responses.
*
* ```
* $httpBackend.expectGET(...);
* $http.get(...);
* $httpBackend.flush();
* ```
*
* ## Shortcut methods
*
* Shortcut methods are also available. All shortcut methods require passing in the URL, and
* request data must be passed in for POST/PUT requests.
*
* ```js
* $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 $http.jsonp}
* - {@link ng.$http#patch $http.patch}
*
*
* ## 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:
*
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
* - `Accept: application/json, text/plain, * / *`
* - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
* - `Content-Type: application/json`
* - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
* - `Content-Type: application/json`
*
* To add or overwrite these defaults, simply add or remove a property from these configuration
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
* with the lowercased HTTP method name as the key, e.g.
* `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
*
* The defaults can also be set at runtime via the `$http.defaults` object in the same
* fashion. For example:
*
* ```
* module.run(function($http) {
* $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'
* });
* ```
*
* In addition, you can supply a `headers` property in the config object passed when
* calling `$http(config)`, which overrides the defaults without changing them globally.
*
* To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
* Use the `headers` property, setting the desired header to `undefined`. For example:
*
* ```js
* var req = {
* method: 'POST',
* url: 'http://example.com',
* headers: {
* 'Content-Type': undefined
* },
* data: { test: 'test' }
* }
*
* $http(req).success(function(){...}).error(function(){...});
* ```
*
* ## Transforming Requests and Responses
*
* Both requests and responses can be transformed using transformation functions: `transformRequest`
* and `transformResponse`. These properties can be a single function that returns
* the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
* which allows you to `push` or `unshift` a new transformation function into the transformation chain.
*
* ### Default Transformations
*
* The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
* `defaults.transformResponse` properties. If a request does not provide its own transformations
* then these will be applied.
*
* You can augment or replace the default transformations by modifying these properties by adding to or
* replacing the array.
*
* Angular provides the following default transformations:
*
* Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
*
* - If the `data` property of the request configuration object contains an object, serialize it
* into JSON format.
*
* Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
*
* - If XSRF prefix is detected, strip it (see Security Considerations section below).
* - If JSON response is detected, deserialize it using a JSON parser.
*
*
* ### Overriding the Default Transformations Per Request
*
* If you wish override the request/response transformations only for a single request then provide
* `transformRequest` and/or `transformResponse` properties on the configuration object passed
* into `$http`.
*
* Note that if you provide these properties on the config object the default transformations will be
* overwritten. If you wish to augment the default transformations then you must include them in your
* local transformation array.
*
* The following code demonstrates adding a new response transformation to be run after the default response
* transformations have been run.
*
* ```js
* function appendTransform(defaults, transform) {
*
* // We can't guarantee that the default transformation is an array
* defaults = angular.isArray(defaults) ? defaults : [defaults];
*
* // Append the new transformation to the defaults
* return defaults.concat(transform);
* }
*
* $http({
* url: '...',
* method: 'GET',
* transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
* return doTransform(value);
* })
* });
* ```
*
*
* ## Caching
*
* To enable caching, set the request configuration `cache` property to `true` (to use default
* cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
* When the cache is enabled, `$http` stores the response from the server in the specified
* cache. The next time the same request is made, the response is served from the cache without
* sending a request to the server.
*
* Note that even if the response is served from cache, delivery of the data is asynchronous in
* the same way that real requests are.
*
* If there are multiple GET requests for the same URL that should be cached using the same
* cache, but the cache is not populated yet, only one request to the server will be made and
* the remaining requests will be fulfilled using the response from the first request.
*
* You can change the default cache to a new object (built with
* {@link ng.$cacheFactory `$cacheFactory`}) by updating the
* {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set
* their `cache` property to `true` will now use this cache object.
*
* If you set the default cache to `false` then only requests that specify their own custom
* cache object will be cached.
*
* ## Interceptors
*
* Before you start creating interceptors, be sure to understand the
* {@link ng.$q $q and deferred/promise APIs}.
*
* For purposes of global error handling, authentication, or any kind of synchronous or
* asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
* able to intercept requests before they are handed to the server and
* responses before they are handed over to the application code that
* initiated these requests. The interceptors leverage the {@link ng.$q
* promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
*
* The interceptors are service factories that are registered with the `$httpProvider` by
* adding them to the `$httpProvider.interceptors` array. The factory is called and
* injected with dependencies (if specified) and returns the interceptor.
*
* There are two kinds of interceptors (and two kinds of rejection interceptors):
*
* * `request`: interceptors get called with a http `config` object. The function is free to
* modify the `config` object or create a new one. The function needs to return the `config`
* object directly, or a promise containing the `config` or a new `config` object.
* * `requestError`: interceptor gets called when a previous interceptor threw an error or
* resolved with a rejection.
* * `response`: interceptors get called with http `response` object. The function is free to
* modify the `response` object or create a new one. The function needs to return the `response`
* object directly, or as a promise containing the `response` or a new `response` object.
* * `responseError`: interceptor gets called when a previous interceptor threw an error or
* resolved with a rejection.
*
*
* ```js
* // register the interceptor as a service
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
* return {
* // optional method
* 'request': function(config) {
* // do something on success
* return config;
* },
*
* // optional method
* 'requestError': function(rejection) {
* // do something on error
* if (canRecover(rejection)) {
* return responseOrNewPromise
* }
* return $q.reject(rejection);
* },
*
*
*
* // optional method
* 'response': function(response) {
* // do something on success
* return response;
* },
*
* // optional method
* 'responseError': function(rejection) {
* // do something on error
* if (canRecover(rejection)) {
* return responseOrNewPromise
* }
* return $q.reject(rejection);
* }
* };
* });
*
* $httpProvider.interceptors.push('myHttpInterceptor');
*
*
* // alternatively, register the interceptor via an anonymous factory
* $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
* return {
* 'request': function(config) {
* // same as above
* },
*
* 'response': function(response) {
* // same as above
* }
* };
* });
* ```
*
* ## Security Considerations
*
* When designing web applications, consider security threats from:
*
* - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
* - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
*
* 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 [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
* allows third party website to turn your JSON resource URL into
* [JSONP](http://en.wikipedia.org/wiki/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:
* ```js
* ['one','two']
* ```
*
* which is vulnerable to attack, your server can return:
* ```js
* )]}',
* ['one','two']
* ```
*
* Angular will strip the prefix, before processing the JSON.
*
*
* ### Cross Site Request Forgery (XSRF) Protection
*
* [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which
* an unauthorized site can gain your user's private data. Angular provides a mechanism
* to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
* (by default, `XSRF-TOKEN`) and sets it as an 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. The header will not be set for
* cross-domain requests.
*
* To take advantage of this, your server needs to set a token in a JavaScript readable session
* cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR 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 sent the request. The token must be
* unique for each user and must be verifiable by the server (to prevent the JavaScript from
* making up its own tokens). We recommend that the token is a digest of your site's
* authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
* for added security.
*
* The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
* properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
* or the per-request config object.
*
*
* @param {object} config Object describing the request to be made and how it should be
* processed. The object has following properties:
*
* - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
* - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
* - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned
* to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be
* JSONified.
* - **data** – `{string|Object}` – Data to be sent as the request message data.
* - **headers** – `{Object}` – Map of strings or functions which return strings representing
* HTTP headers to send to the server. If the return value of a function is null, the
* header will not be sent. Functions accept a config object as an argument.
* - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
* - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
* - **transformRequest** –
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
* transform function or an array of such functions. The transform function takes the http
* request body and headers and returns its transformed (typically serialized) version.
* See {@link ng.$http#overriding-the-default-transformations-per-request
* Overriding the Default Transformations}
* - **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.
* See {@link ng.$http#overriding-the-default-transformations-per-request
* Overriding the Default Transformations}
* - **paramSerializer** - {string|function(Object<string,string>):string} - A function used to prepare string representation
* of request parameters (specified as an object).
* Is specified as string, it is interpreted as function registered in with the {$injector}.
* - **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/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
* for more information.
* - **responseType** - `{string}` - see
* [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
*
* @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.
* - **statusText** – `{string}` – HTTP status text of the response.
*
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending
* requests. This is primarily meant to be used for debugging purposes.
