调用自定义的方法接口.ashx一般处理程序 借鉴了别人网页抓取的类

描述：近段时间写接口，还要调用别人的接口，写好写但是调用不知道啊！刚开始也知道怎么开始，感觉简单不就是调用吗？但是实施起来，汗...对我一个新手来说第一次接触，所以也是自学成才吧！下次登录的时候把源码带上....

 

//源码

string jsonStr = Tools.Tool.getHttpRequestweb("你获得的接口地址");

string sttNumber = Tools.Tool.GetTransData(jsonStr);

/// <summary>

/// 解析JSON数据

/// </summary>

/// <param name="jsonText"></param>

/// <returns></returns>

public static string GetTransData(string jsonText)

{

     JavaScriptSerializer s =new JavaScriptSerializer();

            Dictionary<string,object> JsonData = (Dictionary<string,     object>)s.DeserializeObject(jsonText);

            Dictionary<string,object> trades_sold_get_response = (Dictionary<string,object>)JsonData;

            returntrades_sold_get_response["code"].ToString();

 }

 

if (sttNumber == "1")

{

//我这儿1代表的是成功

}

 publicstatic stringgetHttpRequestweb(stringurl)

        {

            stringresult = "";

            try{ result = GrabHtml(url); }

            catch(Exception ex) { returnex.Message; }

            returnresult;
