WCF在运行时更改端点地址

Question

我的第一个WCF示例正在运行.我有一个网站上的主机有很多绑定.因此,我已将此添加到我的web.config中.

<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>

这是我的默认绑定http://id.web,它使用以下代码.

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

我现在正在尝试在运行时设置端点地址.即使它与上述代码的地址相同.

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？

另外这里是我的客户配置,由Ladislav Mrnka提出要求

 <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,您的第一个示例中定义的端点地址不完整.您还必须定义端点标识,如客户端配置中所示.在代码中,您可以尝试这样做:

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();

valamas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

这是我用于最近测试的一个简单示例.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

的app.config

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

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;
    }
}

履行

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