wcf - 仅使用手动代码调用 WCF 服务(无配置或自动生成代码)

Question

我大致遵循 WCF The Right Way ... The Manual Way 中的方法设置我的 WCF 服务。

我有一个手动生成的代理类，如下所示:

// Setup a client so we can call our web services.
public class EmployeeClient :IEmployeeService
{
    private readonly IEmployeeService EmployeeChannel;

    public EmployeeClient(Binding binding, string address)
    {
        var endpointAddress = new EndpointAddress(address);

        EmployeeChannel = new ChannelFactory<IEmployeeService>
                                 (binding, endpointAddress).CreateChannel();
    }

    public EmployeeResponse SaveOrUpdateEmployee(EmployeeContract employee)
    {
        return EmployeeChannel.SaveOrUpdateEmployee(employee);
    }
}

然后我想调用其中一些服务。但我不想使用任何配置文件(我正在设置一些集成测试，并且我不需要更多的依赖项。)

我目前正在尝试这样称呼他们:

serviceHost = SelfServiceHost.StartupService();

employeeClient = new EmployeeClient(new BasicHttpBinding(), 
                                    SelfServiceHost.StartUpUrl);

EmployeeResponse employeeResponse = employeeClient.SaveOrUpdateEmployee(emp);

当我这样做时，我得到了这个异常:

System.ServiceModel.ProtocolException: Content Type text/xml; charset=utf-8 was not supported by service http://localhost:8090/EmployeeService. The client and service bindings may be mismatched. ---> System.Net.WebException: The remote server returned an error: (415) Cannot process the message because the content type 'text/xml; charset=utf-8' was not the expected type 'application/soap+xml; charset=utf-8'..

我需要做什么才能调用仅使用代码的服务？

根据您的描述，绑定(bind)未以兼容的方式配置。

我怀疑 WCF 主机具有 wsHttpBinding 并且您的客户端具有 BasicHttpBinding 或类似...
