WCF：如何真正使用 WSHttpBinding？我得到了异常

Question

我创建了一个 WCF 服务：

Shared.dll：

[ServiceContract(ConfigurationName = "ICalculator")]
public interface ICalculator
{
    [OperationContract()]
    int Add(int a, int b);
}

服务器：

[ServiceBehavior()]
public class Calculator : ICalculator
{
    public int Add(int a, int b) { return a + b; }
}

客户端（尝试#1）：

public class CalculatorClient : ClientBase<ICalculator>, ICalculator
{
    private static Binding binding = new WSHttpBinding("MyConfig");
    private static EndpointAddress remoteAddress = new EndpointAddress(...);

    public CalculatorClient() : base(binding, remoteAddress) { }

    public int Add(int a, int b)
    {
        return Channel.Add(a, b); //Exception
    }
}

客户端（尝试#2）： -- 注意：我添加了一个服务引用，而不是自己创建一个 CalculatorClient（.NET 为我创建了它）。

static void Main(string[] args)
{
    Binding binding = new WSHttpBinding("MyConfig");
    EndpointAddress remoteAddress = new EndpointAddress(...);
    CalculatorClient client = new CalculatorClient(binding, remoteAddress);
    int result = client.Add(5, 4); //Exception
}

客户端（尝试＃3）： - 我将其更改为 BasicHttpBinding() 而不是

static void Main(string[] args)
{
    Binding binding = new BasicHttpBinding("MyConfig");
    EndpointAddress remoteAddress = new EndpointAddress(...);
    CalculatorClient client = new CalculatorClient(binding, remoteAddress);
    int result = client.Add(5, 4); //This works!
}

app.config：

<system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="MyConfig" /> <!-- did not add anything to this yet -->
      </wsHttpBinding>
    </bindings>
</system.serviceModel>

The exception I get is: Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost/CalculatorService.svc. The client and service bindings may be mismatched. I don't see how they can be mismatched when I use a shared dll file between my server and client. The BasicHttpBinding works, just not the WSHttpBinding (I haven't even attempted WS2007HttpBinding.

异常：[System.ServiceModel.ProtocolException] {“内容类型 application/soap+xml；服务不支持 charset=utf-8 http://localhost/CalculatorService.svc 客户端和服务绑定可能不匹配。”} 内部异常：[System.Net.WebException] 远程服务器返回错误：(415) 无法处理消息，因为内容类型为“application/soap+xml;” charset=utf-8' 不是预期的类型 'text/xml；字符集=utf-8'..

您需要设置要在 WSHttpBinding

使用示例客户端/服务器 WSHttpBinding 进行更新，默认安全

客户端

    class Program
    {
        static void Main(string[] args)
        {
          var calcClient = new CalcClient();
          int i = 1;
          int j = 2;
          Console.WriteLine("Result of Adding {0} and {1} is {2}", i, j, calcClient.Add(i, j));
          Console.ReadKey();
        }
    }

    public class CalcClient : ICalculator
    {
        public CalcClient()
        {
            CalcProxy = ChannelFactory.CreateChannel(new WSHttpBinding(), new EndpointAddress("http://localhost:5050/CalcServer"));
        }

        ICalculator CalcProxy { get; set; }

        public int Add(int a, int b)
        {
            return CalcProxy.Add(a, b);
        }
    }

服务器

class Program
    {
        static void Main(string[] args)
        {
            var host = new ServiceHost(typeof (CalcSvr));
            host.AddServiceEndpoint(typeof (ICalculator), new WSHttpBinding(), "http://localhost:5050/CalcServer");
            host.Open();
            Console.WriteLine("Server Running");
            Console.ReadKey();
        }
    }
