public class MobCookieManager {//转载请标明出处：http://blog.csdn.net/goldenfish1919/article/details/46890245private MobCookieManager(){}/*** 应用启动的时候调用，參考：{@link CookieManager#getInstance CookieManager.getInstance()}* */public static void init(Context context){CookieSyncManager.createInstance(context);}public static String getCookie(String url){CookieManager cookieManager = CookieManager.getInstance();return cookieManager.getCookie(url);}/*** http://stackoverflow.com/questions/16007084/does-android-webkit-cookiemanager-works-on-android-2-3-6* */public static void setCookies(String url, Map<String, List<String>> headerFields) {if (null == headerFields) {return;}List<String> cookies = headerFields.get("Set-Cookie");if (null == cookies) {return;}CookieSyncManager.getInstance().startSync();for (String cookie : cookies) {setCookie(url, cookie);}CookieSyncManager.getInstance().sync();}private static void setCookie(String url, String cookie) {CookieManager cookieManager = CookieManager.getInstance();cookieManager.setAcceptCookie(true);if(cookie.indexOf("Expires") < 0){cookie = addExpireToCookie(cookie);}cookieManager.setCookie(url, cookie);}/*** http://stackoverflow.com/questions/8547620/what-is-a-session-cookie* */private static String addExpireToCookie(String cookie) {Date expireDate = new Date(new Date().getTime() + 24L*60*60*1000);String datestr =DateUtil.format(DateUtil.east8ToGmt(expireDate), DateUtil.FORMAT_GMT);String arr[] = cookie.split(";");StringBuilder sb = new StringBuilder();sb.append(arr[0]);sb.append("; ").append("Expires=").append(datestr);if(arr.length > 1){for(int i=1; i<arr.length; i++){sb.append(";").append(arr[i]);}}return sb.toString();}}
