message=server无法识别http头soapaction:error的值

嗨,伙计们, 我创建了一个Web服务。我可以使用soapui访问Web服务,但是当我试图调用代码时,我会得到这个错误。 有什么想法吗?

好的,Web服务代码如下所示:

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[WebServiceBindingAttribute(Name = "SoapBinding", Namespace = "xyz")]
[System.ComponentModel.ToolboxItem(false)]
[WebService(Namespace = "http://Search")]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class Stub : System.Web.Services.WebService
{
    public Stub()
    {
        Log.Debug(this,string.Format("this is just a test message"));
    }


    [WebMethod]
    public Response searchAsset(Request serviceTag)
    {
    }

我的客户代码是:

Search _search = new Search();
_search.url;
_search.n.wcred;
_search.searchAsset(request);
