WCF 啓用multipleSiteBindingsEnabled 狀況下報終結點地址錯誤

報錯信息以下：

Server Error in '/MyWcfService' Application.

When 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' is set to true in configuration, the endpoints are required to specify a relative address. If you are specifying a relative listen URI on the endpoint, then the address can be absolute. To fix this problem, specify a relative uri for endpoint 'http://127.0.0.1/MyWcfService/Calculatorservice.svc'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

配置文件：

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <behaviors>
      <serviceBehaviors>
        <behavior name="metadataBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />

    </services>

 

根據報錯提示，在啓用multipleSiteBindingsEnabled="true"的狀況下，須要爲終結點指定相對uri。

給定終結點地址一個base address：

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <behaviors>
      <serviceBehaviors>
        <behavior name="metadataBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="metadataBehavior" name="MyWcf.MyWcfService.CalculatorService">
        <endpoint binding="wsHttpBinding" contract="MyWcf.MyWcfContracts.ICalculator"/>
        <host>
          <baseAddresses>
            <!--將service發佈到IIS上的配置,需配置IIS虛擬目錄，例如：MyWcfService-->
            <!--<add baseAddress="http://localhost/MyWcfService/Calculatorservice.svc"/>-->
            <!--將service發佈到VS web deployment上的配置,項目-Property設置了虛擬目錄「/」，若是發佈在http://localhost/MyWcfService下，須要設置虛擬目錄爲「/MyWcfService」-->
            <add baseAddress="http://localhost:2821/Calculatorservice.svc"/>
          </baseAddresses>
        </host>
      </service>
      <service behaviorConfiguration="metadataBehavior" name="MyWcf.MyWcfService.DealWithFault">
        <endpoint binding="wsHttpBinding" contract="MyWcf.MyWcfContracts.IDealWithFault"/>
        <host>
          <baseAddresses>
            <!--將service發佈到VS web deployment上的配置-->
            <add baseAddress="http://localhost:2821/DealWithFault.svc"/>
          </baseAddresses>
        </host>
      </service>
    
    </services>

以下：

「address在終結點裏，簡單理解就是地址，終結點地址。

你能夠配置address爲相對，也能夠是所有完整格式的地址。當你有基地址時，這裏能夠使用相對地址，終結點的地址就是 基地址+相對地址。

當你使用完整的地址格式，那終結點地址就不會使用 基地址+相對地址。

IIS部署的時候，默認會有一個基地址Baseaddress，這個是根據你WCF服務程序的配置生成的。

若是你打算提供完成的地址格式，可是這個完成的地址格式 和Baseaddress 不匹配，好比端口不同，就會出錯。

address換成「」，目的就是使用默認的Baseaddress+「」。避免了你本身設置的和Baseaddress 不匹配的問題。」
