Question

我正在使用供应商的SOAP API。我跟着this example但是在尝试执行客户端命令时遇到了一个奇怪的错误。我对SOAP很陌生，但据我所知，它听起来像是认证不对的。目前，我的代码是：

    private bool EmailExists(string email)
    {
        try
        {
            WSHttpBinding myBinding = new WSHttpBinding();
            myBinding.Security.Mode = SecurityMode.Transport;

            myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;

            EndpointAddress ea = new EndpointAddress("https://api.subscribermail.com/ws/latest/smrecipient?wsdl");

            var smrecipientClient = new smrecipient.smrecipientPortTypeClient(myBinding, ea);
            smrecipientClient.ClientCredentials.UserName.UserName = "[obfuscated]";
            smrecipientClient.ClientCredentials.UserName.Password = "[obfuscated]";

            smrecipientClient.Open();

            var data = smrecipientClient.queryRecipientByEmail(email);

            smrecipientClient.Close();

            if (data != null && !string.IsNullOrEmpty(data.id)) return true;
        }
        catch (Exception ex)
        {
            return false;
        }

        return false;
    }

当我跳过var data = smrecipientClient.queryRecipientByEmail(email);时，我在catch块中看到以下错误：

{"Did not understand \"MustUnderstand\" header(s):{http://www.w3.org/2005/08/addressing}Action, {http://www.w3.org/2005/08/addressing}To"}

没有内部异常，但堆栈跟踪是：

Server stack trace:

   at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc)

   at [myApp].Web.Controllers.SubscriptionsController.EmailExists(String email) in C:\Dev\[myApp]\my-website\Web\Controllers\SubscriptionsController.cs:line 128

我确实看到this SO thread但是不理解解决方案（如何在我的示例中通过代码设置WSS密码类型）。另外，我的一位同事说我需要完全不同地进行身份验证并更新Web服务的Reference.cs，以便主类继承自Microsoft.Web.Services3.WebServicesClientProtocol，但问题是，Web服务的Reference.cs没有有一个主要的班级。

WsHttpBinding用于更高级的WS相关可靠消息传递。在你的场景中，简单的BasicHttpBinding也可以正常工作。

你能使用basicHttpBinding吗？：

    <basicHttpBinding> 
     <binding name="https"> 
      <security mode="Transport"> 
       <message clientCredentialType="Basic"/> 
      </security>
     </binding> 
    </basicHttpBinding>

不明白“MustUnderstand”标题
