一、请求ashx的例子：
[html] view
plain copy
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Request.aspx.cs" Inherits="Ashx_Request" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>请求ashx的例子</title>
<script type="text/javascript" src="../Scripts/jquery-1.4.1.min.js"></script>
<script type="text/javascript">
$(function () {
//POST请求，数据类型为text
/* $.ajax({
type: "POST",
url: "Response.ashx",
contentType: "application/text;charset=utf-8;",
dataType: "text",
success: function (res) {
var re = res;
alert(re);
},
error: function (xmlRes, err, c) {
var xml = xmlRes;
alert(err);
}
});*/
//GET请求，类型为text
/*$.get(
"Response.ashx",
function (res) {
alert(res);
}
)*/
//GET请求,带参数类型为text
/*$.get(
"Response.ashx",
{ "param": "我是请求的传递参数" },
function (res) {
alert(res);
}
);*/
//GET请求，类型为xml
/*$.get(
"Response.ashx",
function (res) {
alert($(res).find("gonghui").text());
}
);*/
//Ajax的GET请求，类型为xml
/*$.ajax({
type: "GET",
url: "Response.ashx",
contentType: "application/xml;charset=utf-8;",
dataType: "xml",
success: function (res) {
var re = $(res).find("gonghui").text();
alert(re);
},
error: function (xmlRes, err, c) {
var xml = xmlRes;
alert(err);
}
});*/
//Ajax的POST请求，类型为json
$.ajax({
type: "POST",
url: "Response.ashx",
contentType: "application/json;charset=utf-8;",
dataType: "json",
success: function (res) {
var re = res;
alert(re);
},
error: function (xmlRes, err, c) {
var xml = xmlRes;
alert(err);
}
});
})
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>

</body>
</html>
后台Request.cs
[csharp] view
plain copy
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Ashx_Request : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Session["sk"] = "我是请求页中请求的session数据";
}
}
ashx的代码：
[csharp] view
plain copy
<%@ WebHandler Language="C#" Class="Response" %>
using System;
using System.Web;
using System.Web.SessionState;
public class Response : IHttpHandler,IRequiresSessionState {
public void ProcessRequest (HttpContext context) {
//RequestSession(context);
//GetRequest(context);
//GetRequestParam(context);
//GetRequestXml(context);
RequestJson(context);
}
public bool IsReusable {
get {
return false;
}
}
private void RequestSession(HttpContext context)
{
context.Response.ContentType = "text/plain";
string sk = context.Session["sk"] as string;
context.Response.Write(sk);
}
private void GetRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Write("Hello World");
}
private void GetRequestParam(HttpContext context)
{
context.Response.ContentType = "text/plain";
string param = context.Request["param"] ?? "";
context.Response.Write("传递参数值为：" + param);
}
private void GetRequestXml(HttpContext context)
{
context.Response.ContentType = "application/xml";
context.Response.Write("<gonghui>Hello World</gonghui>");
}
private void RequestJson(HttpContext context)
{
context.Response.ContentType = "application/json";
context.Response.Write("[\"Hello World.\"]");
}
}
二、请求webservice方法
Request页面的关键代码：
[javascript] view
plain copy
$(function () {
//Ajax使用POST请求，传递参数
/*$.ajax({
type: "POST",
url: "WebService.asmx/GetMyName",
data: "{'name':'gonghui'}", //请求webservice方法的时候,必须这样传递参数，如果遇到单引号，注意转码。
//data:"name=acles", // 请求webservice方法的时候，不能这样传递参数，会报“无效的JSON基元的错误”
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function (res) {
alert(res.d);
},
error: function (xmlRes, err, c) {
alert(err);
}
});*/
/*$.ajax({
type: "GET",
url: "WebService.asmx/GetXml",
contentType: "application/xml;charset=utf-8;",
dataType: "xml",
success: function (res) {
var my = $(res).find("gonghui").text();
alert(my);
}
});*/
$.ajax({
type: "POST",
url: "WebService.asmx/GetXmlPost",
contentType: "application/xml;charset=utf-8;",
dataType: "xml",
success: function (res) {
var my = $(res).find("string").text();
alert(my);
}
});
})
WebService的关键代码：
[csharp] view
plain copy
[WebMethod]
public string GetMyName(string name) {
return "这是WebService页面的值,这是Request传递的参数值：" + name;
}
[WebMethod]
[System.Web.Script.Services.ScriptMethod(UseHttpGet=true)]
public System.Xml.XmlDocument GetXml() {
string xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><gonghui>我是通过Get方式请求返回的xml</gonghui>";
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.LoadXml(xml);
return doc;
}
[WebMethod]
public string GetXmlPost() {
return "我是通过POST方式请求返回的XML";
}
三、请求Aspx页面的例子
Request页面的关键代码：
[javascript] view
plain copy
//直接请求页面的方法,其实请求本身页面和其他页面都是一样的，无非就是地址不一样
$(function () {
//请求自身页面
/*$.get(
"Request.aspx",
{ "token": "ajax" },
function (data) {
$("#dataShow").text(data);
}
);*/
//请求其它页面
/*$.ajax({
type: "GET",
url: "Response.aspx",
data: { token: "ajax" },
dataType: "json",
contentType: "application/json;charset=utf-8",
success: function (data) {
var arr = data;
$.each(arr, function (idx, item) {
alert(item.StudentID + "/" + item.Hometown);
});
},
error: function (d, c, e) {
var dd = d;
}
});*/
//请求自身页面方法(get方法)，返回是自身页面的html源码
/*$.get(
"Request.aspx/RequestMethod",
function (data) {
$("#dataShow").text(data);
}
);*/
//请求页面，带参数
$.ajax({
type: "POST",
url: "Response.aspx/RequestMethod1",
data: "{'msg':'这是一个msg参数值'}",
contentType: "application/json;charset=utf-8", //这句话不要忘了
dataType: "json",
success: function (res) {
$("#dataShow").text(res.d);
},
error: function (xmlReq, err, c) {
$("#dataShow").text(err);
}
});
})
Response.cs的关键代码：
[csharp] view
plain copy
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
StreamReader reader = new StreamReader(Request.InputStream);
string dd = reader.ReadToEnd();
if ((Request["token"] ?? "") == "ajax")
{
//Response.ContentType = "application/Json";
//Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.Clear();
Response.Write("[{\"StudentID\":1,\"Name\":\"tmac\",\"Hometown\":\"GuangDong\"},{\"StudentID\":2,\"Name\":\"gonghui\",\"Hometown\":\"HuNan\"}]");
Response.Flush();
Response.End();
}
//Response.Write(RequestMethod());
}
}
[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod(UseHttpGet = true)]
public static string RequestMethod()//方法一定是静态的
{
return "";
}
[System.Web.Services.WebMethod]
public static string RequestMethod1(string msg)
{
return "这是一个Response页面值,由Request页面的Ajax传入的值：" + msg;
}
