关于soap 调用xml web服务

[cpp_1]

[WebService (Description ="temperature service", Namespace ="http://aaa/webapplication1/webservices")]

[WebMethod]
public double tocelsius(double tf)
{
return (5d/9d)*(tf-32);
}

[WebMethod]
public double tofahrenheit(double tc)
{
return (9d/5d)*(tc+32);
}
这是我写的一个xml web服务

我现在想问
怎么在写一个页面（a.htm）去调用这个xml web服务（用soap，http-post我知道）

添加web引用.

用Javascript 的ActiveXObject来访问.要自己写XML代码详见：http://blog.csdn.net/hjf1223/archive/2005/03/07/313551.aspx

var userID = "3011";
var myService = "http://192.168.7.108/WebService/NewsService.asmx" ;
var myMethod = "http://tempuri.org/HasNewMessage";
var requestHttp = new ActiveXObject("Microsoft.XMLHTTP");
var requestBody = "";
requestBody = requestBody + "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" ;

requestBody = requestBody + "<soap:Envelope ";
requestBody = requestBody + "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" ";
requestBody = requestBody + "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" " ;
requestBody = requestBody + "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" ;

requestBody = requestBody + " <soap:Body>\n" ;
requestBody = requestBody + " <HasNewMessage xmlns=\"http://tempuri.org/\">\n" ;
requestBody = requestBody + " <userID>" + userID + "</userID>\n";
requestBody = requestBody + " </HasNewMessage>\n";
requestBody = requestBody + " </soap:Body>\n";
requestBody = requestBody + "</soap:Envelope>";
requestHttp.Open("POST",myService,false);
requestHttp.SetRequestHeader("Content-Type","text/xml;charset=gb2312");
requestHttp.SetRequestHeader("SOAPAction",myMethod);
requestHttp.Send(requestBody);// 发送请求
var result = requestHttp.ResponseXML; //返回请求,结果保存在XML中,要拆解出来
var pos1 = result .xml.indexOf("<HasNewMessageResult>");

var pos2 = result .xml.indexOf("</HasNewMessageResult>");
var len = pos2 - pos1 - ("<HasNewMessageResult>").length;

var userName = result.xml.substr(pos1 + ("<HasNewMessageResult>").length , len);
pos1 = result.xml.indexOf("<mailCount>");

pos2 = result.xml.indexOf("</mailCount>");
len = pos2 - pos1 - ("<mailCount>").length;

var mailCount = result.xml.substr(pos1 + ("<mailCount>").length , len);

pos1 = result.xml.indexOf("<pendingCount>");

pos2 = result.xml.indexOf("</pendingCount>");

len = pos2 - pos1 - ("<pendingCount>").length;

var pendingCount= result.xml.substr(pos1 + ("<pendingCount>").length , len);

[cpp_1]

http-post
是用一个htm表单来实现的
soap要这么复杂啊？

去中文gotdotnet看怎么用

参考下面的代码 http://ms.mblogger.cn/xuzhong/posts/16578.aspx

演示调用你的tocelsius方法



var objHTTP = new ActiveXObject("MSXML2.XMLHTTP");
var xmlDOC = new ActiveXObject("MSXML.DOMDocument");

var strWebserviceURL = "http://localhost/testss/Service1.asmx/tocelsius";

var strRequest = "tf=111";
objHTTP.Open( "POST", strWebserviceURL, false);


objHTTP.SetRequestHeader( "Content-Type", "application/x-www-form-urlencoded");
objHTTP.Send(strRequest);

var bOK = xmlDOC.load(objHTTP.responseXML);

if(objHTTP.Status==200)
{
xmlDOC.save("c:\\aaa.xml");
}

不过，象这样的方法，在ASP,VB中也一样是可用的。
