Question

我创建并部署了一个非常简单的WCF服务。但是当从IE访问它时，我得到了这个：

HTTP Error 500.19 - Internal Server Error
Description: The requested page cannot be accessed because the related configuration  
data for the page is invalid. 

Error Code: 0x80070005 

Notification: BeginRequest 

Module: IIS Web Core 

Requested URL: http://localhost:80/ProductsService/ProductsService.svc 

Physical Path: C:\Users\Administrator\Documents\Visual Studio 2008\Projects\ProductsService\ProductsService\ProductsService.svc 

Logon User: Not yet determined 

Logon Method: Not yet determined

Config Error: Cannot read configuration file 

Config File: \\?\C:\Users\Administrator\Documents\Visual Studio 2008\Projects \ProductsService\ProductsService\web.config 

Config Source:    -1: 
                   0:

More Information... This error occurs when there is a problem reading the  configuration file for the Web server or Web application. In some cases, the event logs  may contain more information about what caused this error.

这是我的web.config文件的内容：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    </configSections>
    <dataConfiguration defaultDatabase="AdventureWorksConnection" />
    <connectionStrings>
        <add name="AdventureWorksConnection" connectionString="Database=AdventureWorks;    Server=(localhost)\SQLEXPRESS;Integrated  Security=SSPI"
            providerName="System.Data.SqlClient" />
    </connectionStrings>

  <system.serviceModel>
    <services>
      <service name="Products.ProductsService">
        <endpoint address=""
        binding="basicHttpBinding"
        contract="Products.IProductsService" />
      </service>
    </services>
  </system.serviceModel>

</configuration>

Answer 1

好吧，看起来您的服务根本没有公开元数据交换 - 您至少需要添加serviceMetadata行为，以便客户端可以查询服务的元数据，以及是否希望能够使用浏览器，您还需要在该serviceMetadata行为上启用httpGet：。

像这样扩展你的web.config：

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Metadata">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="Products.ProductsService" behaviorConfiguration="Metadata">
        <endpoint address=""
        binding="basicHttpBinding"
        contract="Products.IProductsService" />
      </service>
    </services>
  </system.serviceModel>
