第三部分 03 使用HTTP GET进行调用
一 只需为WebService添加一个属性[ScriptMethod(UseHttpGet = true)]
二 WebService
using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Script.Services;
/// <summary>
/// SimpleWebService 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class SimpleWebService : System.Web.Services.WebService
{
public SimpleWebService()
{
}
[WebMethod]
[ScriptMethod(UseHttpGet = true)]
public int Add(int a, int b)
{
return a + b;
}
}
三 Default.aspx

SimpleWebService.Add(num1, num2, onSucceeded);
}
function onSucceeded(result, context)
{
$get("result").innerHTML = result;
}
</script>
</head>
<body>
<form id="form1" runat="server">
