协议肯定是使用http协议,因为soap协议本身也是基于http协议。期中第二种方式:只有webservice3.5以后版本才可以成功

 

第一种方式:构造soap格式的body,注意加粗的黄色标识,比如:

createXMLHttpRequest();
    var data;
    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:Header>"
    data = data + '<UserSoapHeader xmlns="http://tempuri.org/">'
    data = data + "<UserName>admin</UserName>"
    data = data + "<Pwd>faaaa</Pwd>"
    data = data + "</UserSoapHeader>"
    data = data + "</soap:Header>"
    
    
    data = data + '<soap:Body>';
    data = data + '<'+method+' xmlns="'+_Namespace+'">';
    for(var i=0;i<variable.length;i++)
    {
      data = data + '<'+variable[i]+'>'+value[i]+'</'+variable[i]+'>';
    }
    data = data + '</'+method+'>';
    data = data + '</soap:Body>';
    data = data + '</soap:Envelope>';
      
    xmlhttp.onreadystatechange=handleStateChange;
    xmlhttp.Open("POST",url, true);
    xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=utf-8");
    xmlhttp.SetRequestHeader ("Content-Length",getlen(data));
    xmlhttp.SetRequestHeader ("SOAPAction",_Namespace+method);
    xmlhttp.Send(data);
   

第二种方式(我没使用过,想着不会成功):构造json格式的body,比如:

createXMLHttpRequest();  

urlhttp://....../a.asmx/webservice方法名

body使用json数据格式

xmlhttp.SetRequestHeader ("Content-Type","application/json; charset=utf-8");
    xmlhttp.SetRequestHeader ("Content-Length",getlen(body));
