WCF 抛出异常，表示服务器拒绝了客户端凭据，WCF 中 NetTCP 的默认安全模式是什么 [英] WCF throws exception that the server has rejected the client credentials, what is the default security mode for NetTCP in WCF

问题描述

WCF 作为 Windows 服务部署在服务器中.客户端是一个windows窗体应用程序.当客户端与 WCF 服务器交互时，这里是否进行了某种身份验证?

The WCF is deployed as a windows service in the server. And the client is a windows form applicaiton. When the client is interacting with the WCF server, is there any kind of authentication going on here?

我想知道WCF中NetTCP的默认安全模式是什么?我的配置文件中与安全无关，如下所示.那么默认值是多少?

I want to know what is the default security mode for NetTCP in WCF? I had nothing related with security in my config file as below. So what is the default?

推荐答案

NetTcpBinding 的传输安全模式为 Transport，ClientCredentialType 为 Windows.这相当于下面的设置.

The transport security mode of the NetTcpBinding is Transport and the ClientCredentialType is Windows. This is equivalent to the following settings.

<netTcpBinding>
  <binding name="netTcp">
    <security mode="Transport">
      <transport clientCredentialType="Windows" />
    </security>
  </binding>
</netTcpBinding>

所以当你使用客户端代理类调用服务时，可以参考如下代码.

So when you use the client proxy class to call the service, you could refer to the following code.

ServiceReference1.ServiceClient client = new ServiceReference1.ServiceClient();
            client.ClientCredentials.Windows.ClientCredential.UserName = "administrator";
            client.ClientCredentials.Windows.ClientCredential.Password = "abcd1234!";
var result = client.SayHello();
