代碼如下:
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
[webservice(namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
public Service ()
{
//uncomment the following line if using designed components
//InitializeComponent();
}
[webmethod]
public string SayHelloTo(string Name)
{
return "Hello "+Name;
}
}
還是俗了點。:)
2. js調(diào)用webservice+xmlhttp的實現(xiàn)部分。
代碼如下:
<html>
<title>Call webservice with javascript and xmlhttp.</title>
<body>
<script language="javascript"><!--
//test function with get method.
function RequestByGet(data){
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
//Webservice location.
var URL="http://localhost:1323/WebSite6/Service.asmx/SayHelloTo?Name=Zach";
xmlhttp.Open("GET",URL, false);
xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=utf-8");
xmlhttp.SetRequestHeader ("SOAPAction","http://tempuri.org/SayHelloTo");
xmlhttp.Send(data);
var result = xmlhttp.status;
//OK
if(result==200) {
document.write(xmlhttp.responseText);
}
xmlhttp = null;
}
//test function with post method
function RequestByPost(value)
{
var data;
data = '<?xml version="1.0" encoding="utf-8"?>';
datadata = data + '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">';
datadata = data + '<soap:Body>';
datadata = data + '<SayHelloTo xmlns="http://tempuri.org/">';
datadata = data + '<Name>'+value+'</Name>';
datadata = data + '</SayHelloTo>';
datadata = data + '</soap:Body>';
datadata = data + '</soap:Envelope>';
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
var URL="http://localhost:1323/WebSite6/Service.asmx";
xmlhttp.Open("POST",URL, false);
xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=gb2312");
xmlhttp.SetRequestHeader ("SOAPAction","http://tempuri.org/SayHelloTo");
xmlhttp.Send(data);
document.write( xmlhttp.responseText);
}
// --></script>
<input type="button" value="CallWebserviceByGet" onClick="RequestByGet(null)">
<input type="button" value="CallWebserviceByPost" onClick="RequestByPost('Zach')">
</body>
</html>
對于使用post方法需要發(fā)送的那堆東東可以在webservice的測試頁面中找到，自己拼湊加上對應的參數(shù)就可以。
通過style.behavior來實現(xiàn)的方法(比較簡單)
function getfemale()
{
//第一個參數(shù)是webservice的url，后面是名稱
female.useService("news.asmx?WSDL","news");
//設(shè)置一個回調(diào)函數(shù)，service返回結(jié)果的時候回調(diào)；第一個參數(shù)是回調(diào)函數(shù)的名稱，后面的是webservice的參數(shù)
