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> |
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) %> |
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。
