});示例2: get
get(url: string): Promise<string> {
var completer: PromiseCompleter < string >= PromiseWrapper.completer();
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);

// responseText is the old-school way of retrieving response (supported by IE8 & 9)
// response/responseType properties were introduced in XHR Level2 spec (supported by IE10)
var response = isPresent(xhr.response) ? xhr.response : xhr.responseText;
// normalize IE9 bug (http://bugs.jquery.com/ticket/1450)
var status = xhr.status === 1223 ? 204 : xhr.status;
// fix status code when it is 0 (0 status is undocumented).
// Occurs when accessing file resources or on Android 4.1 stock browser
// while retrieving files from application cache.
