调用样例：
string url = "http://apis.baidu.com/3023/shorturl/shorten";
string param = "url_long=" + HttpUtility.UrlEncode("http://www.baidu.com");
//"url_long=http%3A%2F%2Fapistore.baidu.com%2Fastore%2Fshopready%2F1973.html";
// http://t.cn/RUOn4qB
string sResult = Gbi.Extensions.RequestBaiduAPIStore(url, param);
string sShortLink = Gbi.Extensions.GetJsonNodeValue("urls", sResult);
if (!string.IsNullOrEmpty(sShortLink))
{
sShortLink = Gbi.Extensions.GetJsonNodeValueFromFirstArrayItem("url_short", sShortLink);
sResult = sShortLink;
}
