在脚本语言中调用WebService的方法

 1． 在JavaScript中调用WebService

<script language="javascript">function PostRequestData(URL,data){  var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");  xmlhttp.Open("POST",URL,false);  xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=utf-8");  xmlhttp.SetRequestHeader ("SOAPAction","http://tempuri.org/myService/test/isNumner");  try {    xmlhttp.Send(data);    var result = xmlhttp.status;  }  catch(ex) {    return("0" + ex.description + "&#124;" + ex.number);  }  if(result==200) {    return("1" + xmlhttp.responseText);  }  xmlhttp = null;}function loadit(value){  var url = 'http://localhost/myService/test.asmx';  var data ;  var r;  data = '<?xml version="1.0" encoding="utf-8"?>';  data = 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/">';  data = data + '<soap:Body>';  data = data + '<isNumner xmlns="http://tempuri.org/myService/test">';  data = data + '<str>'+value+'</str>';  data = data + '</isNumner>';  data = data + '</soap:Body>';  data = data + '</soap:Envelope>';    r=PostRequestData(url,data);  document.write(r);}loadit('5');</script>当然，还可以使用微软的htc组件来实现，可以到这里下载:http://msdn.microsoft.com/workshop/author/webservice/webservice.htc<script language="javascript">function timer(){  service.useService("http://localhost/myService/test.asmx?WSDL","test");  service.test.callService(callback,"isNumner",'gdh');}function callback(res){  if (!res.error)    time.innerText=res.value;}</script><div id="service" style="behavior:url(webservice.htc)"></div><span id="time"></span>2. 在Asp中调用WebService<％@LANGUAGE="VBSCRIPT" CODEPAGE="936"％><％Dim strxmlDim str'定义soap消息strxml = "<?xml version='1.0' encoding='tf-8'?>"strxml = strxml & "<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/'>"strxml = strxml & "<soap:Body> "strxml = strxml & "<isNumner xmlns='http://tempuri.org/myService/test'>"strxml = strxml & "<str>4</str>"strxml = strxml & "</isNumner>"strxml = strxml & "</soap:Body>"strxml = strxml & "</soap:Envelope>"'定义一个XML的文档对象，将手写的或者接受的XML内容转换成XML对象set x = createobject("Microsoft.DOMDocument")'初始化XML对象'将手写的SOAP字符串转换为XML对象x.loadXML strxml'初始化http对象Set h = createobject( "Microsoft.XMLHTTP")'向指定的URL发送Post消息h.open "POST","http://localhost/myService/test.asmx",Falseh.setRequestHeader "Content-Type","text/xml"h.setRequestHeader "SOAPAction","http://tempuri.org/myService/test/isNumner"h.send (strxml)While h.readyState <> 4Wend'显示返回的XML信息str = h.responseText'将返回的XML信息解析并且显示返回值Set x = createobject("MSXML2.DOMDocument")x.loadXML strstr = x.childNodes(1).Textresponse.write(str)％>3．在.net中调用WebService　　在.net中调用WebService就方便多了，没有必要自己写soap消息了，以上都是用XMLHTTP来发送WebService请求的，在.net只要添加了web引用，会自动为你创建一个代理类。然后使用代理类就像用自己定义的类一样方便。4、如何在ASP中调用由Delphi编写的WebServiceQ：那么又如何在ASP中调用由Delphi编写的WebService呢？A：上微软网站下个Microsoft SOAP Toolkit 3.0安装，就可以在asp里调用webservice了，调用方法如下：Microsoft SOAP Toolkit（Msst）可以到微软网站免费下载：http://download.microsoft.com/download/xml/Install/3.0/W982KMeXP/EN-US/SoapToolkit30.EXE  <%    'Calling   a   Web   service   using   Microsoft   SOAP   Toolkit   3.0       OPTION   EXPLICIT       Dim   strWebSvcWSDLURL    Dim   objSOAPClient       strWebSvcWSDLURL   ="http://localhost/jfgl/jfglWebSrv.dll/wsdl/IjfglWebSrv"     Set   objSOAPClient   =   Server.CreateObject("MSSOAP.soapClient30")    objSOAPClient.ClientProperty("ServerHTTPRequest")   =   True       objSOAPClient.MSSoapInit   strWebSvcWSDLURL,   "",   ""       dim   s    s   =   objSOAPClient.Get_sql_Time   //调用soap里的方法    response.write   s    %>
