.ashx获取post body

 

ashx 获取ajax Post到后台json数据

前台页面代码：

var json = [{ "Name": "Pavan Kumar Pabothu", "Age": 27, "ID": 361621 }, { "Name": "Reddaiah Raju Padhmaraju", "Age": 27, "ID": 362541 }, { "Name": "Denish Raju Padhmaraju", "Age": 26, "ID": 368941 }];

$.ajax({

type: "POST",

// url: "CommonFiles.aspx/DeleteFiles",

url: "../data/AjaxTest.ashx",

//data: "{Id:'" + deleteid + "'}",

data: { 'myjson': json },

contentType: "application/json; charset=utf-8",

dataType: 'json',

success: function (data) {

var result = data.d;

if (result == "error")//失败

{

}

loadFileSort(id);

}

});

Ashx 代码：

 

StringBuilder rsb = new StringBuilder();

var mRequest = context.Request;

int bytelengg=(int)mRequest.InputStream.Length;

using (var reader = new StreamReader(mRequest.InputStream,Encoding.UTF8))

{

var read = new Char[bytelengg];

var count = reader.Read(read, 0, bytelengg);

while (count > 0)

{

var str = new string(read, 0, count);

rsb.Append(str);

count = reader.Read(read, 0, bytelengg);

}

reader.Close();

reader.Dispose();

mRequest.InputStream.Close();

mRequest.InputStream.Dispose();

}

然后通过反序列字符串转换成对

 

 

public void ProcessRequest(HttpContext context)

{

context.Response.ContentType = "text/plain";

//context.Response.Write(context.Request.Form["param2"]);

HttpRequest request = context.Request;

Stream stream = request.InputStream;

string json = string.Empty;

string responseJson = string.Empty;

if (stream.Length != 0)

{

StreamReader streamReader = new StreamReader(stream);

json = streamReader.ReadToEnd();

context.Response.Write(json);

}

context.Response.Write("没有获取到json");

}

 

参数方式：

context.Response.ContentType = "text/plain";

            if (context.Request.QueryString["My"] != null)

            {

                context.Response.Write("参数:"+ context.Request.QueryString["My"]);

            }

            else

            {

                context.Response.Write("没有参数！Hello World");

            }
