Question

我已将服务引用添加到第三方Web服务，并且在从控制台应用程序进行WCF调用时，出现以下错误消息：

System.ServiceModel.ProtocolException: 'The content type application/xml; charset=utf-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 610 bytes of the response were: '<?xml version="1.0"?>

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="urn:CancelServiceResponse">

<soapenv:Body>

<tns:CancelServiceResponse>

<CancelServiceResult>

<Status_Code>FAILED</Status_Code>

                <Status_Description>Service_ID= not found.</Status_Description>

                <Order_ID></Order_ID>

</CancelServiceResult>

</tns:CancelServiceResponse>

</soapenv:Body>

</soapenv:Envelope>

配置文件如下：

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IB2BService">
                <security mode="TransportWithMessageCredential">
                    <message clientCredentialType="UserName" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="https://thirdpartyendpointaddress"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IB2BService"
            contract="b2bService.IB2BService" name="BasicHttpBinding_IB2BService" />
    </client>
</system.serviceModel>

有人可以建议，要解决此问题需要做什么？我已经搜索了整个SO，却找不到解决方法。

在我看来，代码片段没有问题。必须注意的一件事是，确保服务器和客户端之间的绑定是一致的，并且具有正确的服务端点。在客户端，我们可以使用添加服务参考工具生成配置。我认为最好的答复是给您一个带有TransportWithMessageCredential的调用服务的示例。
服务器端（10.157.13.69。控制台应用程序）

class Program
    {
        static void Main(string[] args)
        {
            Uri uri = new Uri("https://localhost:11011");
            BasicHttpBinding binding = new BasicHttpBinding();
            binding.Security.Mode = BasicHttpSecurityMode.TransportWithMessageCredential;
            binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

            using (ServiceHost sh = new ServiceHost(typeof(MyService), uri))
            {
                sh.AddServiceEndpoint(typeof(IService), binding, "");
                ServiceMetadataBehavior smb;
                smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
                if (smb == null)
                {
                    smb = new ServiceMetadataBehavior()
                    {
                        HttpsGetEnabled = true
                    };
                    sh.Description.Behaviors.Add(smb);
                }
                sh.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = System.ServiceModel.Security.UserNamePasswordValidationMode.Custom;
                sh.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new CustUserNamePasswordVal();
                Binding mexbinding = MetadataExchangeBindings.CreateMexHttpsBinding();
                sh.AddServiceEndpoint(typeof(IMetadataExchange), mexbinding, "mex");

                sh.Opened += delegate
                {
                    Console.WriteLine("Service is ready");
                };
                sh.Closed += delegate
                {
                    Console.WriteLine("Service is clsoed");
                };


                sh.Open();

                Console.ReadLine();
                sh.Close();
                Console.ReadLine();
            }

        }
    }
    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        string SayHello();
    }
    public class MyService : IService
    {
        public string SayHello()
        {
            return $"Hello Stranger,{DateTime.Now.ToLongTimeString()}";
        }
    }
    internal class CustUserNamePasswordVal : UserNamePasswordValidator
    {
        public override void Validate(string userName, string password)
        {
            if (userName != "jack" || password != "123456")
            {
                throw new Exception("Username/Password is not correct");
            }
        }
    }

将证书绑定到端口。

netsh http add sslcert ipport=0.0.0.0:11011 certhash=6e48c590717cb2c61da97346d5901b260e983850 appid={ED4CE60F-6B2E-4EE6-828F-C1A6A1B12565}

客户端（通过添加服务引用来调用服务）

var client = new ServiceReference1.ServiceClient();
            client.ClientCredentials.UserName.UserName = "jack";
            client.ClientCredentials.UserName.Password = "123456";
            try
            {
                var result = client.SayHello();
                Console.WriteLine(result);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }

配置文件（自动生成）

<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService">
                    <security mode="TransportWithMessageCredential" />
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://10.157.13.69:11011/" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IService" contract="ServiceReference1.IService"
                name="BasicHttpBinding_IService" />
        </client>
</system.serviceModel>

请随时告诉我是否有什么可以帮忙的。
