托管 WCF 时出现 500 服务器错误

Question

也许你可以帮助我，因为我在这里真的很茫然。

我正在尝试在子域的 IIS 上托管我的 WCF 服务。

首先，这是我的文件结构：

http://s18.postimage.org/eqmjxb00n/Serv.jpg

bin 里面是我的 .dll，代表我的接口和它的实现。

这是 web.config 文件：

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="false" targetFramework="4.0" />
  </system.web>    
    <system.serviceModel>
        <services>
            <service name="AuthenticatorService.Authenticator">
                <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
                    name="AuthEndpoint" contract="AuthInterface.IAuthenticator" />
                <endpoint address="" binding="mexHttpBinding" name="MetadataEndpoint"
                    contract="IMetadataExchange" />
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior>
                    <serviceMetadata httpGetEnabled="True"/>
                    <serviceDebug includeExceptionDetailInFaults="False" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

它可以在本地工作，但是当我上传到 IIS 时，它只会出现 500 个服务器错误。

谢谢！

如果有任何用处，这里是来自详细错误页面的消息：

Module  ServiceModel-4.0
Notification    AuthenticateRequest
Handler svc-Integrated-4.0
Error Code  0x00000000
Requested URL   http://service.swiftposter.com:80/auth.svc
Logon Method    Anonymous
Logon User  Anonymous

编辑：我启用了 ELMAH 日志记录，最后得到了一条有意义的消息：

System.ArgumentException: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. If your service is being hosted in IIS you can fix the problem by setting 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'. Parameter name: item

我打算开始研究这个错误，但我在这里发布以防万一有人知道出了什么问题。

堆栈跟踪：

Answer 1

我通过将它添加到我的 web.config 来修复错误。

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

我认为这是因为我有 2 个都使用 http 的绑定。也许其他人可以详细说明。

Answer 2

错误 500 标识任何类型的服务器错误...尝试从 localhost 访问服务（IIS 的默认设置仅在本地显示错误）。

也尝试将 IIS 设置编辑为“将错误发送到浏览器” 要么 在 Internet 信息服务 (IIS) 管理器 > 您的网站 > 错误页面 > 属性中，然后选择详细错误

通过这种方式，您可以看到您的服务引发的真正错误。

还要检查是否在您的应用程序池中选择了正确的框架版本

Answer 3

您的服务地址和服务的元数据地址不应相同。应该是这样的：

<system.serviceModel>
 <services>
   <service name="AuthenticatorService.Authenticator">
      <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
                name="AuthEndpoint" contract="AuthInterface.IAuthenticator" />
       <endpoint address="mex" binding="mexHttpBinding" name="MetadataEndpoint"
                contract="IMetadataExchange" />
   </service>
  </services>
  ...
</system.serviceModel>
