具体调用的代码:
'向指定的文件写入文本, 并指定是否是添加内容 Function Z_WriteFile(sFileName, sText, bAppend) Dim fs, fso, iomode if bAppend = True Then iomode = 8 'ForAppending else iomode = 2 'ForWriting end if set fs = CreateObject("Scripting.FileSystemObject") set fso = fs.OpenTextFile(sFileName, iomode, True) '第三个参数表明文件不存在,则新建文件 fso.WriteLine sText fso.Close set fso = Nothing set fs = Nothing Z_WriteFile = True End Function Dim objHttp, xmlDoc, sText, sXml Set objHTTP = CreateObject("MSXML2.XMLHTTP") Set xmlDOC = CreateObject("MSXML.DOMDocument") strWebserviceURL = "http://192.168.2.39/webservice1/service.asmx/addition" strRequest = "i=2&j=3" objHTTP.Open "POST", strWebserviceURL, False objHTTP.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded" objHTTP.Send(strRequest) if objHTTP.Status = 200 Then Dim sNodeList, sResult xmlDOC.load(objHTTP.responseXML) set sNodeList = xmlDoc.getElementsByTagName("double") sResult = sNodeList(0).Text sText = "2+3=" & sResult else sText = "调用WebService出错,请检查" end if Z_WriteFile "ResultVoice.txt", sText, False
webservice是由vs.net2010(c#)开发的,核心代码如下:
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 () { //如果使用设计的组件,请取消注释以下行 //InitializeComponent(); } [WebMethod(Description = "Let's say \"Hello\"")] public string Hi() { return "Hello World, Happy New Year"; } [WebMethod(Description = "Hello JoeBlack")] public string Hello(string username) { return username + ", Happy New Year"; } [WebMethod(Description = "求和的方法")] public double addition(double i, double j) { return i + j; } [WebMethod(Description = "求差的方法")] public double subtract(double i, double j) { return i - j; } [WebMethod(Description = "求积的方法")] public double multiply(double i, double j) { return i * j; } [WebMethod(Description = "求商的方法")] public double division(double i, double j) { if (j != 0) return i / j; else return 0; } }
为了让WebService启用对HttpGet和HttpPost协议的支持(默认配置只支持Soap协议),需要在WebService项目的Web.config中添加以下内容:
<system.web> <!-- 设置 compilation debug="true" 可将调试符号 插入已编译的页面中。 但由于这会影响性能,因此请仅在开发过程中将此值 设置为 true。 --> <compilation debug="true" targetFramework="4.0"> </compilation> <!-- 通过 <authentication> 节可以配置 安全身份验证模式,ASP.NET 使用该模式来识别来访用户身份。 --> <!-- 配置WebService支持HttpPost和HttpGet协议 --> <webServices> <protocols> <add name="HttpPost" /> <add name="HttpGet" /> </protocols> </webServices> <authentication mode="Windows"/>
运行下就可以看到处理后的结果,都写入到了ResultVoice.txt文件中。
