jsoup使用cookie：

		Set<Cookie> cookie_set = LoadCSDN.load();
//		WebClient wc = new WebClient();
		HashMap<String, String> map = new HashMap<String,String>();
		for (Cookie cookie : cookie_set) {
			map.put(cookie.getName(), cookie.getValue());
//			wc.getCookieManager().addCookie(cookie);
		}
		Document doc = Jsoup.connect(url).cookies(map).get();
