我创建了由IDummyService实施的DummyService合同。我正在使用以下配置尝试self-host此服务:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
<system.serviceModel>
    <services>
      <service name="DummyService.DummyService" behaviorConfiguration="MEX">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8733/" />
          </baseAddresses>
        </host>
        <endpoint address="DummyService" 
                  binding="basicHttpBinding" 
                  contract="DummyService.IDummyService"/>
        <endpoint address="net.tcp://localhost:8734/DummyService/" 
                  binding="netTcpBinding" 
                  bindingConfiguration = "TransactionalTCP" 
                  contract="DummyService.IDummyService"/>
        <endpoint address="mex" binding="mexHttpBinding"    contract="IMetadataExchange" />
      </service>
    </services>
    <bindings>
      <netTcpBinding>
        <binding name = "TransactionalTCP" transactionFlow = "true"/>
      </netTcpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name = "MEX">
          <serviceMetadata/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

运行良好的服务主机代码并启动这些端点。但是,当我尝试访问以下端点时,我在Chrome浏览器中收到Page isn't working错误。

http://localhost:8733/DummyService/
http://localhost:8733/mex/

但是,我可以访问页面http://localhost:8733/

我不明白为什么会这样。

我认为端点地址是附加到主机address

的端点的baseaddress条目

任何想法我做错了什么?

感谢。

您已应用属性 behaviorConfiguration =&#34; MEX&#34; 但未使用它,因此出于安全原因,您需要启用默认情况下在WCF中为false的元数据发现。

<serviceBehaviors>
        <behavior name = "MEX">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>

现在,当您浏览http://localhost:8733/DummyService/http://localhost:8733/mex/时,浏览器中将显示空白页,而不是默认错误页。

如果您想测试 net.tcp 端点,也可以使用WCFtestclient.exe。
