WCF 在运行时更改地址异常

Question

我在使用自定义端点连接到 WCF 服务时遇到问题。

我有通过 WCF 服务与数据库通信的 excel 插件。我创建了服务，一切正常。我的 Excel 插件项目的 ServiceReference 中引用了 WCF 服务。

但是现在，我想要一个选项来设置运行 WCF 服务的服务器。因此，我让用户输入服务 URI，并尝试使用绑定和 EndpointAdrress 创建 ServiceClient。 但是，如果我使用服务器的 EndPointAddress 创建 ServiceClient，即使服务器地址与来自 ServiceReference 的地址相同，也会引发 EndpointNotFoundException。

我认为app.config和web.config文件可能有问题，但我不知道在哪里。

App.Config（Excel 插件）

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_ICampaignService" />
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost:58375/CampaignService.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICampaignService"
            contract="CampaignDatabaseService.ICampaignService" name="BasicHttpBinding_ICampaignService" />
    </client>
    <behaviors>
        <serviceBehaviors>
            <behavior name="">
                <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="false" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
        multipleSiteBindingsEnabled="true" />
</system.serviceModel>

Web.Config（WCF 服务）

<?xml version="1.0"?>
<configuration>
  <connectionStrings>
<add name="CampaignDatabase" connectionString="Data Source=dev\sql14;Initial Catalog=TSQL2012;Integrated Security=True;User id=addin_test;Password=testpassword;"/>
  </connectionStrings>
  <appSettings>
     <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
   </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5"/>
  </system.web>
   <system.serviceModel>
     <behaviors>
       <serviceBehaviors>
      <behavior>
      <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<protocolMapping>
    <add binding="basicHttpBinding" scheme="http" />
</protocolMapping>    
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
   <modules runAllManagedModulesForAllRequests="true"/>
    <!--
    To browse web app root directory during debugging, set the value below to true.
    Set to false before deployment to avoid disclosing web app folder information.
     -->
  <directoryBrowse enabled="true"/>
 </system.webServer>

 </configuration>

这就是我创建 ServiceClient 的方式

 EndpointAddress serviceAddress = new EndpointAddress(Properties.Settings.Default.serviceAddress);
 BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
 CampaignServiceClient connector = new CampaignServiceClient(binding,serviceAddress);

感谢您的意见

如果我想在运行时更改地址，我将使用 channelFactory 而不是生成的 serviceClient。 因为从 web.config 中生成了一个 fetching thinks，这在运行时更改是不好的。

类似的东西。请更改为真正的设置。

//define binding 
BasicHttpBinding myBinding = new BasicHttpBinding();

//define endpoint url (where service is deployed)
EndpointAddress myEndpoint = new EndpointAddress("http://localhost:58375/CampaignService.svc"); //change to real endpoint 

//Use channel factory instead of generated one
ChannelFactory<ICampaignService> myChannelFactory = new ChannelFactory<ICampaignService>(myBinding, myEndpoint); //Change to you WCF interface
ICampaignService myServiceClient = myChannelFactory.CreateChannel();

//and call it            
var result = myServiceClient.Add(1,1); //input to your method
//other methods

((IClientChannel)myServiceClient).Close();
myChannelFactory.Close();
