Question

我对WCF很新，并尝试使用自定义用户名和密码创建WCF服务。我知道我应该将userName和Password设置为代理的ClientCredentials，但出于某种原因，我没有这样的属性......

我认为它与我的合同有关，所以这里是：

我的合约代码：

namespace Contracts
{    
    [ServiceContract]
    public interface ICalc
    {
        [OperationContract]
        CalcResponse Add(double x, double y);

        [OperationContract]
        CalcResponse Substract(double x, double y);

        [OperationContract]
        CalcResponse Multiply(double x, double y);

        [OperationContract]
        CalcResponse Divide(double x, double y);
    }
}

在我的客户端，我所要做的就是：

ChannelFactory<ICalc> channel = new ChannelFactory<ICalc>("calcEndpoint");
ICalc proxy = channel.CreateChannel();

proxy.ClientCredentials.UserName.UserName = "USER";
proxy.ClientCredentials.UserName.Password = "PASSWORD";

但我的代理没有ClientCredentials属性

更新我遇到了一些导致其他错误的问题。当我解决它们时，我遇到了一个新错误：

套接字连接已中止。这可能是由错误引起的处理您的消息或超过接收超时远程主机或底层网络资源问题。

我的超时在客户端和服务器中都设置为5分钟。我在不到一分钟的时间内得到了这个错误......

这是我更新的代码：

ChannelFactory<ICalc> channel = new ChannelFactory<ICalc>("calcEndpoint");

var defaultCredentials = channel.Endpoint.Behaviors.Find<ClientCredentials>();
channel.Endpoint.Behaviors.Remove(defaultCredentials);

ClientCredentials loginCredentials = new ClientCredentials();
loginCredentials.UserName.UserName = "Comply";
loginCredentials.UserName.Password = "123456";

channel.Endpoint.Behaviors.Add(loginCredentials); 
ICalc proxy = channel.CreateChannel();

我有一个自定义验证器，我在那里放了一个断点，但它只是没有在那里... 我的验证码：

class CustomUserNameValidator : UserNamePasswordValidator
{
    public override void Validate(string userName, string password)
    {
        if (userName == "comply" && password == "123456")
        {
        }
    }
}

配置（在客户端和服务器上）：

<service name ="WcfServiceLibrary.Service1" behaviorConfiguration ="CustomValidator">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost/CalcIISHost/mex"/>
        <add baseAddress ="net.tcp://localhost:808/CalcIISHost/CalcService"/>
      </baseAddresses>
    </host>
    <endpoint address ="" binding ="netTcpBinding" bindingConfiguration="tcpWithMessageSecurity" contract ="Contracts.ICalc"></endpoint>
    <endpoint address ="net.tcp://localhost:5001/CalcIISHost/mex" binding ="mexTcpBinding" contract ="IMetadataExchange"></endpoint>
  </service>
...
<behavior name="CustomValidator">
      <serviceCredentials>
        <userNameAuthentication
          userNamePasswordValidationMode="Custom"
          customUserNamePasswordValidatorType="WCFClasses.CustomUserNameValidator, WCFClasses"/>
        <serviceCertificate
          findValue="localhost"
          x509FindType="FindBySubjectName"
          storeLocation="CurrentUser"
          storeName="My" />
      </serviceCredentials>
      <serviceMetadata httpGetEnabled ="true"/>
    </behavior>
...
<netTcpBinding>
    <binding name="tcpWithMessageSecurity"  sendTimeout="00:05:00" receiveTimeout="00:05:00">
      <security mode="Message" >
        <message clientCredentialType="UserName"/>
      </security>
    </binding>
  </netTcpBinding>

任何想法我做错了什么？

您可以像这样设置凭据......

删除默认端点行为

ChannelFactory<ICalc> channel = new ChannelFactory<ICalc>("calcEndpoint");
var defaultCredentials = channel.Endpoint.Behaviors.Find<ClientCredentials>();
channel.Endpoint.Behaviors.Remove(defaultCredentials);

创建凭据

ClientCredentials loginCredentials = new ClientCredentials();
loginCredentials.UserName.UserName = "USER";
loginCredentials.UserName.Password = "PASSWORD";

将凭据设置为出厂时的新端点行为

channel.Endpoint.Behaviors.Add(loginCredentials); 
ICalc proxy = channel.CreateChannel();

我建议您向服务添加日志记录，并在 Error.svclog 文件中发布您遇到的异常，在服务app.config中的Configuration标记下添加。

<system.diagnostics>
        <sources>
            <source name="System.ServiceModel"
                    switchValue="Information, ActivityTracing"
                    propagateActivity="true" >
                <listeners>
                    <add name="xml"/>
                </listeners>
            </source>
            <source name="System.ServiceModel.MessageLogging">
                <listeners>
                    <add name="xml"/>
                </listeners>
            </source>
            <source name="myUserTraceSource"
                    switchValue="Information, ActivityTracing">
                <listeners>
                    <add name="xml"/>
                </listeners>
            </source>
        </sources>
        <sharedListeners>
            <add name="xml"
                 type="System.Diagnostics.XmlWriterTraceListener"
                 initializeData="Error.svclog" />
        </sharedListeners>
