JS调用webservice的两种方式

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 = http://www.mamicode.com/‘<?xml version="1.0"encoding="utf-8"?>‘;
    data = http://www.mamicode.com/data + ‘    data = http://www.mamicode.com/data +"<soap:Header>"
    data = http://www.mamicode.com/data + ‘    data = http://www.mamicode.com/data +"<UserName>admin</UserName>"
    data = http://www.mamicode.com/data +"<Pwd>faaaa</Pwd>"
    data = http://www.mamicode.com/data +"</UserSoapHeader>"
    data = http://www.mamicode.com/data +"</soap:Header>"
    
    
    data = http://www.mamicode.com/data + ‘‘;
    data = http://www.mamicode.com/data + ‘<‘+method+‘"‘+_Namespace+‘">‘;
    for(var i=0;i<variable.length;i++)
    {
     data = http://www.mamicode.com/data + ‘<‘+variable[i]+‘>‘+value[i]+‘‘;
    }
    data = http://www.mamicode.com/data + ‘‘;
    data = http://www.mamicode.com/data + ‘
‘;
    data = http://www.mamicode.com/data + ‘
‘;
      
    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));
