System.InvalidOperationException： '已关联绑定实例以侦听

Question

我刚刚启动了一个项目的WCF，它显示了以下异常，但我发现了一些与此问题有关的问题，但我无法在我的代码中找到，我将把我的代码放在这里，请查看并建议我的代码的最佳解决方案。

<system.serviceModel>
<services>
<service name="CompanyService.CompanyService" behaviorConfiguration="mexBehaviour">
<endpoint address="CompanyService" binding="basicHttpBinding" contract="CompanyService.ICompanyPublicService"></endpoint>
<endpoint address="CompanyService" binding="netHttpBinding" contract="CompanyService.ICompanyConfidentialService"></endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/"/>
<add baseAddress="net.tcp://localhost:8091/"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="mexBehaviour">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>

以下是错误异常：

'A binding instance has already been associated to listen URI 'http://localhost:8080/CompanyService'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config. '

Answer 1

您需要修改端点地址的名称：

<services>
<service name="CompanyService.CompanyService" behaviorConfiguration="mexBehaviour">
<endpoint address="CompanyService01" binding="basicHttpBinding" contract="CompanyService.ICompanyPublicService"></endpoint>
<endpoint address="CompanyService02" binding="netHttpBinding" contract="CompanyService.ICompanyConfidentialService"></endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/"/>
<add baseAddress="net.tcp://localhost:8091/"/>
</baseAddresses>
</host>
</service>
</services>
