客户端访问WebService(3)

1,使用Htttp Get 访问方法

简单例子:

WebService代码:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
namespace AJAXEnabledWebApplication4
{
/// <summary>
/// WebService2 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolBoxItem(false)]
[System.Web.Script.Services.ScriptService]
public class WebService2 : System.Web.Services.WebService
{
[WebMethod]
public int GetRandom()
{
return new Random(DateTime.Now.Millisecond).Next();
}
[WebMethod]
//ScriptMethod属性标记
//设置UserHttpGet为true
//通过上面的设置,就可以设置请求方式为Get
[System.Web.Script.Services.ScriptMethod(UseHttpGet=true)]
public int GetRangeRandom(int minValue, int maxValue)
{
return new Random(DateTime.Now.Millisecond).Next(minValue, maxValue);
}
}
}

 
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="AJAXEnabledWebApplication4.WebForm1" %>

<!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>无标题页</title>

</head>

<body>

    <form id="form1" runat="server">

    <asp:ScriptManager runat="server" ID="scriptManager1" >

    <Services>

    <asp:ServiceReference Path="WebService2.asmx" Inlinescript="true" />

    </Services>

    </asp:ScriptManager>

    <input type="button" value="GetRandom (Post)" onclick="getRandom()" />

    <input type="button" value="Get Range Random (Get)" onclick="getRangeRandom(50,100)" />

    <script type="text/javascript" language="javascript" >
    function getRandom(){
          AJAXEnabledWebApplication4.WebService2.GetRandom(onsucceed);
    }
    function getRangeRandom(minValue,maxValue){
        AJAXEnabledWebApplication4.WebService2.GetRangeRandom(minValue,maxValue,onsucceed);
    }
    function onsucceed(result){
        alert(result);
    }

    </script>

    </form>

</body>

</html>

在页面生成的代理中,可以看到一些区别,还可以通过httpWatch观察post和get 的一些小的区别.

2,服务器方法重载的调用和客户端重载的调用

简单例子:

webservice代码:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
namespace AJAXEnabledWebApplication4
{
/// <summary>
/// WebService1 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolBoxItem(false)]
[System.Web.Script.Services.ScriptService]
public class WebService1 : System.Web.Services.WebService
{
[WebMethod]
public int GetRandom()
{
return new Random(DateTime.Now.Millisecond).Next();
}
[WebMethod(MessageName="GetRangeRandom")]
//可以通过 MessageName=""对方法进行重新命名
public int GetRandom(int min, int max)
{
return new Random(DateTime.Now.Millisecond).Next(min, max);
}
}
}

aspx页面代码:

 
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="AJAXEnabledWebApplication4._Default" %>

<!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>Untitled Page</title>

</head>

<body>

    <form id="form1" runat="server">

        <asp:ScriptManager ID="ScriptManager1" runat="server">

        <Services>

        <asp:ServiceReference Path="WebService1.asmx" Inlinescript="true" />

        </Services>

        </asp:ScriptManager>

        <input type="button" value="Get Random" onclick="GetRandom()" />

        <input type="button" value="Get Range Random" onclick="GetRandom(50,100)" />

        <script type="text/javascript" language="javascript">
        function GetRandom(minValue,maxValue){
          //js 函数默认的 arguments可以判断传入参数的数量,从而模仿了客户端方法重载
           if(arguments.length!=2){
            AJAXEnabledWebApplication4.WebService1.GetRandom(onsucceed);
            }else{
            AJAXEnabledWebApplication4.WebService1.GetRangeRandom(minValue,onsucceed);
           
            }
        }
        
        function onsucceed(result){
            alert(result);
        }

        </script>

    </form>

</body>

</html>
