Soap 错误或 https 相关错误

Question

我有两个 asp.net 网站（比如 abc 和 pqr）。第一个应用程序“abc”有 web 服务 ListingData.asmx，第二个应用程序 pqr 有一个使用该 web 服务的网页。 “abc”应用程序在 https 上运行，“pqr”在 http 上运行。 'abc site' 上 asmx 的代码是：

    public class ListingAuthHeader : SoapHeader
    {
        public string Username;
        public string Password;
    }

    public class ListingAuthHeaderValidation
    {
    /// <summary>
    /// Validates the credentials of the soap header.
    /// </summary>       

    public static bool Validate(ListingAuthHeader soapHeader)
    {
        if (soapHeader == null)
        {
            throw new NullReferenceException("No soap header was specified.");
        }

        if (soapHeader.Username == null)
        {
            throw new NullReferenceException("Username was not supplied for authentication in SoapHeader.");
        }

        if (soapHeader.Password == null)
        {
            throw new NullReferenceException("Password was not supplied for authentication in SoapHeader.");
        }

        if (soapHeader.Username != "a" || soapHeader.Password != "b")
        {
            throw new Exception("Please pass the proper username and password for this service.");
        }

        return true;
        }
    }

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

    public class ListingData  : System.Web.Services.WebService {


    public ListingAuthHeader CustomSoapHeader;

    [WebMethod]
    [SoapHeader("CustomSoapHeader")]

    public DataSet GetListingData(string countryId, int maxListings)
    {
    ListingAuthHeaderValidation.Validate(CustomSoapHeader);
    // then get data from database
    } 

要使用这个 web 服务，c# 代码是：

    ws.ListingData o = new ws.ListingData();
    ws.ListingAuthHeader h = new ws.ListingAuthHeader();
    h.Username = soapHeaderUsername;
    h.Password = soapHeaderPassword;
    o.ListingAuthHeaderValue = h;
    ds = o.GetListingData(countryId, maxListings);

我已经通过“添加服务参考”添加了网络服务参考

堆栈跟踪显示以下错误：

"{System.Net.WebException：请求失败，响应为空。 在 System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse（SoapClientMessage 消息，WebResponse 响应，流 responseStream，布尔 asyncCall） 在 System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] 参数)"

这两个网站都托管在带有 IIS 7 的 Windows Server Web 上。

过去两天我一直在互联网上搜索以解决此错误，但找不到适用于我的情况的解决方案。

任何意见/建议将不胜感激。

您应该将客户端配置为通过 HTTPS 端点进行通信，如绑定配置。因此，将设置放入应用程序配置并配置服务名称；

  <system.serviceModel>
    <bindings>
     <basicHttpBinding>
          <binding name="HttpsBindindConfiguration">
            <security mode="Transport" />        
          </binding>
    </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://abc/ListData.asmx" binding="basicHttpBinding" bindingConfiguration="HttpsBindindConfiguration" contract="ListDataClient" name="ListDataClient" />
    </client>
  </system.serviceModel>
