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();
url:http://....../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));
