      context.Response.ContentEncoding = Encoding.UTF8;

      Stream inputStream = context.Request.InputStream;

      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;

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：
