WCF 在运行时更改端点地址

Question

我的第一个 WCF 示例正在运行。我在一个有很多绑定的网站上有主机。因此，我已将其添加到我的 web.config 中。

<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>

这是我的默认绑定 http://id.web，它适用于以下代码。

EchoServiceClient client = new EchoServiceClient();
litResponse.Text = client.SendEcho("Hello World");
client.Close();

我现在尝试在运行时设置端点地址。即使它与上面的代码是相同的地址。

EchoServiceClient client = new EchoServiceClient();
client.Endpoint.Address = new EndpointAddress("http://id.web/Services/EchoService.svc"); 

litResponse.Text = client.SendEcho("Hello World");
client.Close();

我得到的错误是：

The request for security token could not be satisfied because authentication failed. 

请建议我如何在运行时更改端点地址？

这里是我的客户端配置，由 Ladislav Mrnka 请求

 <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="WSHttpBinding_IEchoService" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
                    maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                    messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
                    allowCookies="false">
                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                    <reliableSession ordered="true" inactivityTimeout="00:10:00"
                        enabled="false" />
                    <security mode="None" />
                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://id.web/Services/EchoService.svc" binding="wsHttpBinding"
                bindingConfiguration="WSHttpBinding_IEchoService" contract="IEchoService"
                name="WSHttpBinding_IEchoService">
                <identity>
                    <servicePrincipalName value="host/mikev-ws" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>

Answer 1

因此，第一个示例中定义的端点地址不完整。您还必须定义端点身份，如客户端配置中所示。在代码中，您可以尝试以下操作：

EndpointIdentity spn = EndpointIdentity.CreateSpnIdentity("host/mikev-ws");
var address = new EndpointAddress("http://id.web/Services/EchoService.svc", spn);   
var client = new EchoServiceClient(address); 
litResponse.Text = client.SendEcho("Hello World"); 
client.Close();

由 valamas 提供的实际工作最终版本

EndpointIdentity spn = EndpointIdentity.CreateSpnIdentity("host/mikev-ws");
Uri uri = new Uri("http://id.web/Services/EchoService.svc");
var address = new EndpointAddress(uri, spn);
var client = new EchoServiceClient("WSHttpBinding_IEchoService", address);
client.SendEcho("Hello World");
client.Close(); 

Answer 2

这是我最近测试中使用的一个简单示例。
您需要确保服务器和客户端上的安全设置相同。

var myBinding = new BasicHttpBinding();
myBinding.Security.Mode = BasicHttpSecurityMode.None;
var myEndpointAddress = new EndpointAddress("http://servername:8732/TestService/");
client = new ClientTest(myBinding, myEndpointAddress);
client.someCall();

Answer 3

配置程序

<client>
    <endpoint address="" binding="basicHttpBinding" 
    bindingConfiguration="LisansSoap" 
    contract="Lisans.LisansSoap" 
    name="LisansSoap" />
</client>

应用程序

 Lisans.LisansSoapClient test = new LisansSoapClient("LisansSoap",
                         "http://webservis.uzmanevi.com/Lisans/Lisans.asmx");

 MessageBox.Show(test.LisansKontrol("","",""));

Answer 4

我们将 URL 存储在数据库中并在运行时加载它们。

public class ServiceClientFactory<TChannel> : ClientBase<TChannel> where TChannel : class
{
    public TChannel Create(string url)
    {
        this.Endpoint.Address = new EndpointAddress(new Uri(url));
        return this.Channel;
    }
}

执行

var client = new ServiceClientFactory<yourServiceChannelInterface>().Create(newUrl);

Answer 5

您可以创建一个 EndpointAddress 并使用客户端的实例来确定绑定

        EndpointAddress a = new("http://localhost:50415/Service1.svc");
        Service1Client c = new(new Service1Client().Endpoint.Binding, a);
        string result = c.GetData(3);

如果您不介意初始化客户端两次，
