Angular provides following mechanism to - * counter XSRF. When performing XHR requests, the $xhr service reads a token from a cookie - * called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that - * runs on your domain could read the cookie, your server can be assured that the XHR came from - * JavaScript running on your domain. - * - * To take advantage of this, your server needs to set a token in a JavaScript readable session - * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET requests the server - * can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure that only - * JavaScript running on your domain could have read the token. The token must be unique for each - * user and must be verifiable by the server (to prevent the JavaScript making up its own tokens). - * We recommend that the token is a digest of your site's authentication cookie with - * {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}. - * - * @param {string} method HTTP method to use. Valid values are: `GET`, `POST`, `PUT`, `DELETE`, and - * `JSONP`. `JSONP` is a special case which causes a - * [JSONP](http://en.wikipedia.org/wiki/JSON#JSONP) cross domain request using script tag - * insertion. - * @param {string} url Relative or absolute URL specifying the destination of the request. For - * `JSON` requests, `url` should include `JSON_CALLBACK` string to be replaced with a name of an - * angular generated callback function. - * @param {(string|Object)=} post Request content as either a string or an object to be stringified - * as JSON before sent to the server. - * @param {function(number, (string|Object))} success A function to be called when the response is - * received. The success function will be called with: - * - * - {number} code [HTTP status code](http://en.wikipedia.org/wiki/List_of_HTTP_status_codes) of - * the response. This will currently always be 200, since all non-200 responses are routed to - * {@link angular.module.ng.$xhr.error} service (or custom error callback). - * - {string|Object} response Response object as string or an Object if the response was in JSON - * format. - * @param {function(number, (string|Object))} error A function to be called if the response code is - * not 2xx.. Accepts the same arguments as success, above. - * - * @example - <doc:example> - <doc:source jsfiddle="false"> - <script> - function FetchCntl($xhr) { - var self = this; - this.url = 'index.html'; - - this.fetch = function() { - self.code = null;
