c# - 添加对 WCF 的服务引用(失败)

Question

我一直在试验 WCF 并将一个 DataContract 添加到我的服务器并更新了一个 ServiceContract。当第一次将 ServiceReference 添加到客户端时，我在同一台电脑上运行它们，所以我使用了 localhost。我现在尝试通过以太网电缆连接 2 台电脑并以这种方式更新服务引用。我已经将 LAN 上的服务器 IP 地址设置为 192.168.10.10 。单击服务器表单上的按钮时将执行以下代码。

private void btnCommenceService_Click(object sender, EventArgs e)
    {
        host = new ServiceHost((typeof(Service)), new Uri[] { new Uri("http://localhost:9000")});   
        host.AddServiceEndpoint(typeof(IServices),
            new WSDualHttpBinding(),
            "ServerService");

        ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
        smb.HttpGetEnabled = true;
        smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
        host.Description.Behaviors.Add(smb);

        host.Open();
        txtStatus.Text = "Service is open.";
    }

我关闭了两台电脑上的防火墙，并成功地从客户端电脑上 ping 了地址“http://192.168.10.10”。如果我在浏览器中输入该网页，我也设法访问了一些随机网页。

在客户端中，如果我单击我的解决方案并选择“添加服务引用”并输入

“http://192.168.10.10”“http://192.168.10.10:9000”"http://192.168.10.10:9000/ServerService"

所有这些都返回某种形式的错误，通常是以下几行:

The document at the url http://192.168.10.10:9000/ was not recognised as a known document type.
The error message for each known type may help u fix the problem:
-Report from 'XML Schema' is The document format is not recognised(the content type is 'text/html;charset=utf-8').'.
Report from DISCO Document is There was an error downloading `'http://localhost:9000/?disco'.'.` 
Unable to connect to the remote server. 
No connection could be made because the target machine actively refused it 127.0.0.1:9000
etc

有人知道为什么它不能通过 LAN 工作但我可以访问和 ping 地址吗？

尝试像这样更改您的绑定(bind)安全配置

WSDualHttpBinding wsDualBinding= new WSDualHttpBinding();
wsDualBinding.Security.Mode = WSDualHttpSecurityMode.None;
wsDualBinding.Security.Message.ClientCredentialType = MessageCredentialType.None;

然后添加服务端点

host.AddServiceEndpoint(typeof(IServices),wsDualBinding,"ServerService");

希望有用
