XUtil3.0关于Cookie的问题

XUtil3.0实际项目中如何处理Cookie

第一次请求的时候获取Cookie并保存起来

RequestParams params2 = new RequestParams(ConfigConstants.GETHEADPORTRAIT);
//强制表单请求
params2.setMultipart(true);
// 键和值
params2.addBodyParameter("account",username);
//POST请求  
x.http().post(params2, new Callback.CacheCallback<String>() {
    @Override
    public boolean onCache(String result) {
        return false;
    }
    @Override
    public void onSuccess(String result) {
      //提取Cookie 并保存   下次请求前加入header
        DbCookieStore instance = DbCookieStore.INSTANCE;
        List<HttpCookie> cookies = instance.getCookies();
        for (HttpCookie cookie : cookies) {
            String name = cookie.getName();
            String value = cookie.getValue();
            SharePreferenceUtil.setPrefString(getBaseContext(),"Cookiename",name);
            SharePreferenceUtil.setPrefString(getBaseContext(),"Cookievalue",value);
        }
    }

    @Override
    public void onError(Throwable ex, boolean isOnCallback) {

    }

    @Override
    public void onCancelled(CancelledException cex) {

    }

    @Override
    public void onFinished() {

    }
});

再次请求数据的时候取出Cookie 学会要判断Cookie过期的情况

//再次请求数据

String cookiename = SharePreferenceUtil.getPrefString(getBaseContext(), "Cookiename", "");
String cookievalue = SharePreferenceUtil.getPrefString(getBaseContext(), "Cookievalue", "");
RequestParams params2 = new RequestParams(ConfigConstants.LOGINURL);
params2.addHeader("Cookie",  cookiename + "="+ cookievalue);
params2.setMultipart(true);
params2.addBodyParameter("passwd",Md5Utils.MD5(prefString1));
x.http().post(params2, new Callback.CacheCallback<String>() {
    @Override
    public boolean onCache(String result) {
        return false;
    }
    @Override
    public void onSuccess(String result) {


    @Override
    public void onError(Throwable ex, boolean isOnCallback) {
    }
    @Override
    public void onCancelled(CancelledException cex) {
    }
    @Override
    public void onFinished() {
    }
});
