.net调用Java开发的webservice接口（.net中直接web服务引用wsdl），可是有些值就是解析为null，而soapUI监控收发正常

有没有人遇到啊 急求解决方法

经常发现这类问题，主要是返回的数据转换问题造成，一般情况下不要直接引用wsdl的方式（如果的调用.Net开发的webservice可以），用HttpWebRequest方式获取返回的数据，然后再解析，这种方式比引用wsdl成功率高，至于如何传参数，可以用 SoapUI工具进行分析，能看到该怎样传参数 还有用HTTPAnalyzerFull工具可以进行抓包，看看提交和返回的是什么内容 不管是.net 调用java或者Java调用.net，一般用以上两个工具都能解决问题

url：webservice地址 param：提交的参数，一般是xml格式，用SoapUI工具可以查看传的xml格式

public string GetGsReturn(string url, StringBuilder param)//提交到webservice并返回结果
  {
   string responseString = string.Empty;
   try
   {
    byte[] bs = Encoding.UTF8.GetBytes(param.ToString());

    HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
    myRequest.Method = "post";

    myRequest.Headers.Add("SOAPAction", "\"\"");
    myRequest.Headers.Add("Accept-Encoding", "gzip,deflate");
    myRequest.ContentType = "text/xml; charset=utf-8";

    myRequest.KeepAlive = true;
    myRequest.ContentLength = bs.Length;
    myRequest.UserAgent = "Apache-HttpClient/4.1.1 (java 1.5)";

    Stream reqStream = myRequest.GetRequestStream();
    reqStream.Write(bs, 0, bs.Length);

    HttpWebResponse myResponse;
    try
    { myResponse = (HttpWebResponse)myRequest.GetResponse(); }
    catch (WebException ex)
    { myResponse = (HttpWebResponse)ex.Response; }
    if (myRequest != null)
    {
     StreamReader sr = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
     responseString = sr.ReadToEnd();//返回的数据
    }
   }
   catch (Exception ex)
   {
    responseString = ex.Message;
   }
   return responseString;
  }

一个参数用例，具体看你的实际需求

    StringBuilder param = new StringBuilder();
    param.AppendLine("<?xml version='1.0' encoding='utf-8'?>");
    param.AppendLine("<soapenv:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:web='http://webservice.protal.ems.com'>");
    param.AppendLine("<soapenv:Header/>");
    param.AppendLine("<soapenv:Body>");

    param.AppendLine("<web:sendSMS soapenv:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'>");
    param.AppendLine("<enterpriseID xsi:type='xsd:string'>15644</enterpriseID>");
    param.AppendLine("<loginName xsi:type='xsd:string'>admin</loginName>");
    param.AppendLine("<password xsi:type='xsd:string'>511c6269b5eb69538c71ab372529fb1d</password>"); //741123
    param.AppendLine("<smsId xsi:type='xsd:string'></smsId>");
    param.AppendLine("<subPort xsi:type='xsd:string'></subPort>");
    param.AppendLine("<content xsi:type='xsd:string'>" + smstxt + "</content>");
    param.AppendLine("<mobiles xsi:type='xsd:string'>" + tels + "</mobiles>");
    param.AppendLine("<sendTime xsi:type='xsd:string'></sendTime>");
    param.AppendLine("</web:sendSMS>");

    param.AppendLine("</soapenv:Body>");
    param.AppendLine("</soapenv:Envelope>");

    string rtnstr = GetGsReturn(SmsUrl, param);//传送参数并返回结果

为什么我用你的代码返回的是wsdl？

我们调用对方公司的服务（Java写的），我也遇到这个问题， 实在没辙了 ，用了ChinaOneCup的方法可以成功
