你还可以使用WebMethod属性类的CacheDuration属性来在服务器上允许高速缓冲。下面的代码示例显示如何在XML Web服务方法上使用CacheDuration属性来指定输出高速缓冲为60秒。
[C#]
<%@ WebService Language="C#" Class="MathService" %>
using System;
using System.Web.Services;
public class MathService : WebService {
[WebMethod(CacheDuration=60)]
public float Add(float a, float b)
{
return a + b;
}
[WebMethod(CacheDuration=60)]
public float Subtract(float a, float b)
{
return a - b;
}
[WebMethod(CacheDuration=60)]
public float Multiply(float a, float b)
{
return a * b;
}
[WebMethod(CacheDuration=60)]
public float Divide(float a, float b)
{
if (b==0) return -1;
return a / b;
}
}
[Visual Basic]
<%@ WebService Language="VB" Class="MathService" %>
Imports System
Imports System.Web.Services
Public Class MathService
Inherits WebService
<WebMethod(CacheDuration := 60)> _
Public Function Add(a As Single, b As Single) As Single
Return a + b
End Function
<WebMethod(CacheDuration := 60)> _
Public Function Subtract(a As Single, b As Single) As Single
Return a - b
End Function
<WebMethod(CacheDuration := 60)> _
Public Function Multiply(a As Single, b As Single) As Single
Return a * b
End Function
<WebMethod(CacheDuration := 60)> _
Public Function Divide(a As Single, b As Single) As Single
If b = 0 Then
Return - 1
End If
Return a / b
End Function
End Class
当设计你的XML Web服务时，努力遵循如何格式化模式的结构。
XML Web服务使用SOAP作为主要的传送和序列化协议。一个SOAP消息由一个可选择的头体和消息体组成。头部分包含可以被Web服务器体系结构处理的信息。SOAP没有定义任何头。消息体部分包含由应用程序处理的信息，例如用于XML Web服务的参数或返回值。
提供用于你的XML Web服务的文档，如一个静态HTML文件，描述你的服务的操作和数据结构。还包括如何使用这个XML Web服务的示例。不要依靠服务描述或服务帮助页面作为你唯一的文档。
