C# 从WCF服务检索元数据时出错

我创建了一个非常简单的WCF服务，但由于某些原因，我在使用

svcuti

时遇到了问题。我正在使用以下命令：

svcutil http://localhost:8098/IceVSServer/service?wsdl

我得到以下输出：

WS-Metadata Exchange Error
    URI: http://localhost:8098/IceVsServer/service?wsdl

    Metadata contains a reference that cannot be resolved: 'http://localhost:8098/IceVsServer/service?wsdl'.

There was no endpoint listening at http://localhost:8098/IceVsServer/service
?wsdl that could accept the message. This is often caused by an incorrect addres
s or SOAP action. See InnerException, if present, for more details.

The remote server returned an error: (404) Not Found.


HTTP GET Error
    URI: http://localhost:8098/IceVsServer/service?wsdl

There was an error downloading 'http://localhost:8098/IceVsServer/service?wsdl'.

The request failed with HTTP status 404: Not Found.

If you would like more help, type "svcutil /?"

该错误似乎表明我没有MEX端点。我确实这样做了，事实上，如果我把URL放到浏览器中，XML就会立即出现

这是我的app.config：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="IceVSService.IceVsService" behaviorConfiguration="IceVsServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8098/IceVsService/service"/>
          </baseAddresses>
        </host>
        <!-- this endpoint is exposed at the base address provided by host: http://localhost:8098/IceVsService/service  -->
        <endpoint address=""
                  binding="wsHttpBinding"
                  contract="IceVSService.IIceVersioningSystem" />
        <!-- the mex endpoint is explosed at http://localhost:8098/IceVsService/service/mex -->
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="IceVsServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="False"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

您将

HttpGet

与

Mex

混淆。这是发布服务详细信息的两种不同方式—“

元数据交换格式”（MEX）或“
web服务描述语言”（WSDL）

在您的配置中，您已经定义了这两个；但是，您尚未定义
httpgeturl
属性，因此它将被视为空字符串。
因此，您的wsdl地址将是：
http://localhost:8098/IceVsService/service?wsdl
而不是
http://localhost:8098/IceVsServer/service
（IceVsServer未在任何地方定义）

您的mex地址也将与svcutil一起使用：
http://localhost:8098/IceVsService/service/mex
你说得对……就是这样。我累了…漫长的一天哈哈。谢谢你的帮助
