FooService.svc.cs：

[ServiceContract(ProtectionLevel = ProtectionLevel.EncryptAndSign)]
public interface IFooBar
{
    [OperationContract()]
    int Add(int num1, int num2);
}

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
public class FooService : IFooBar
{
    public int Add(int num1, int num2)
    {
        return num1 + num2;
    }
}

我将文件发布到我的服务器（其上有一个ssl证书），但是当我转到网页时：https://localhost:443/FooService.svc我收到以下错误...

必须保护请求消息。这是操作所必需的合约（ 'IFooBar'，的 'http：//tempuri.org/'）。该必须由保护提供保护捆绑（ 'basicHttpBinding的'， 'HTTP：//tempuri.org/'）。

无论是直接访问网址还是从Visual Studio中转到Add Service Reference...，都会发生这种情况。

此外，如果我将[ServiceContract(ProtectionLevel = ProtectionLevel.EncryptAndSign)]更改为[ServiceContract]，则可以正常使用。

WCF 4中HTTP传输的默认绑定是basicHttpBinding。当您将服务合同保护级别设置为加密和签名时，绑定还必须支持消息级别安全性。由于basicHttpBinding不支持消息级安全性，因此您需要手动将服务配置为wsHttpBinding或更改协议映射，如下所示：

<system.serviceModel>
   <protocolMapping>
      <remove scheme="http" />
      <add scheme="http" binding="wsHttpBinding" bindingConfiguration="" />
   </protocolMapping>
... snip ...
</system.serviceModel>
