public void ProcessRequest(HttpContext context)    {      context.Response.ContentType = "application/json";      context.Response.ContentEncoding = Encoding.UTF8;      Stream inputStream = context.Request.InputStream;      Encoding encoding = context.Request.ContentEncoding;      StreamReader streamReader = new StreamReader(inputStream, encoding);      string strJson = streamReader.ReadToEnd();      Param p = JsonConvert.DeserializeObject<Param>(strJson);      int top = Convert.ToInt32(p.Top);      string term = p.Term;            //var result = ...      //context.Response.Write(result.ToJson());    }Source Code

jQuery post数据至ashx

今天给大家分享一个小功能，在jQuery环境中，Post data to ashx进行数据交互。

参考下面代码示例：

$.ajax({           url: '<%= ResolveUrl("~/Handlers/xxx.ashx") %>',              dataType: "json",              type: "POST",              contentType: "application/json; charset=utf-8",              data: JSON.stringify({                top: 10,                term: request.term              }),              success: function (data) {                //...              }            });

jQuery的Post值是使用type: "POST"，上传的数据类型为contentType: "application/json; charset=utf-8"。

从代码示例中，它有2个参考需要上传，top，term。

为了更好在ashx能接收，我们写一个model:

using System;using System.Collections.Generic;using System.Linq;using System.Web;/// <summary>/// Summary description for Param/// </summary>namespace Insus.NET{  public class Param  {    private int _top;    public int Top    {      get { return _top; }      set { _top = value; }    }    private string _term;    public string Term    {      get { return _term; }      set { _term = value; }    }  }}

在ashx处理程序中，我们可以同下面这样接收Post过来的数据：
