最近项目中用到WebView访问新浪支付页面，有个要求是必须是登录状态，否则会报Token过期，然后我简单的将我从cookie中取得的ticket，即一串数字可以代表用户登录的唯一标识作为参数拼接到url路径上，竟然成功了，但是，当在新浪页面进入第二级界面的时候，还会报Token过期，这才意识到，还是新浪网页没有获取到cookie。

    可是ios也是用的webview访问的新浪支付，并且没有设置任何属性，新浪就可以获取到cookie。百度了一番，当然如何获取cookie，自己百度查查吧，我这是已经获取到cookie之后的操作。注意的是要在WebView.loadUrl()之前调用syncCookie方法：

    public  void syncCookie(Context context, String url) {

        try {

            CookieSyncManager.createInstance(context);

            CookieManager cookieManager = CookieManager.getInstance();

            cookieManager.setAcceptCookie(true);

            cookieManager.removeSessionCookie();// 移除

            cookieManager.removeAllCookie();

            //以下是我们在请求中获取到的cookie相关信息，然后存到本地，你需要做的就是 将自己的cookie 中的信息分别取出来 如：

//            cookie0: SFFGDFEID=0F7AE910509938FE024D6F94CB882DCA

//            cookie1： Domain=.dotyre.cn

//            cookie3:  Expires=Sat, 12-Aug-2017 05:41:47 GMT

//            cookie4:  Path=/

            String cookie = SharedPreferencesUtils.getString(context, "cookie0");

            String domain = SharedPreferencesUtils.getString(context, "cookie1");

            String path = SharedPreferencesUtils.getString(context, "cookie4");

            //然后分别拼到StringBuilder 上，然后通过cookieManager.setCookie(url, cookieValue);最后再进行同步，Cook//ieSyncManager.getInstance().sync();

            StringBuilder sbCookie = new StringBuilder();

            sbCookie.append(cookie);

            //       sbCookie.append(String.format(";domain=%s", domain));

            //       sbCookie.append(String.format(";path=%s", path));

            sbCookie.append(";"+domain);

            sbCookie.append(";"+path);

            String cookieValue = sbCookie.toString();

            Log.e("==cookieValue==", cookieValue);

            cookieManager.setCookie(url, cookieValue);

            CookieSyncManager.getInstance().sync();

        } catch (Exception e) {

            Log.e("==异常==", e.toString());

        }

    }

    另外提供一个工具类：

    import java.util.List;
