几种调用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 + "|" + 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> 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 <%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%> <% Dim strxml Dim 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";,False h.setRequestHeader "Content-Type","text/xml" h.setRequestHeader "SOAPAction"," http://tempuri.org/myService/test/isNumner"; h.send (strxml) While h.readyState <> 4 Wend '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 str 'str = x.childNodes(1).Text response.write(str) %> 3.在.net中 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。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
