Question

我在服务器IIS上有一个基本的WCF服务，SQL db也位于其中。

在本地运行它时，它可以正常工作，并且所有服务功能都可以正常工作，但是一旦我发布到服务器IIS，我就会得到

The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service.

仅当我调用/ function

如果我只是转到开始页面，则找不到终点，这与我本地的终点相同。

这是我的service.svc的样子

using System.ServiceModel;
using System.ServiceModel.Web;
using System.ServiceModel.Activation;
using System.Web.Script.Services;
using Newtonsoft.Json.Linq;

namespace myNameSpace
{
    [ServiceContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service
    {


        /// <summary>
        /// ....
        /// </summary>
        /// <returns>string</returns>
        [WebInvoke(UriTemplate = "/NextWeek", Method = "GET")]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public string nextWeek()
        {
            return db.Instance.getNextWeek();
        }

        //this continues for awhile and is basically the same type of functions

    }
}

我还创建了一个global.asax

   public class Global : HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {
            RouteTable.Routes.Add(new ServiceRoute("", new WebServiceHostFactory(), typeof(Service)));
        }
    }

这是我的web.config

我最初遇到404错误，但是我设法解决了该错误，表明它的服务没有终点。

          <serviceMetadata httpGetEnabled="true" />
          <!--

          <serviceDebug includeExceptionDetailInFaults="true" />

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
  </system.webServer>
  <connectionStrings>
    .....
  </connectionStrings>
</configuration>

我已经尝试了一些在Microsoft网站上找到的配置选项，但是并没有帮助。

谢谢。

我注意到您使用ORM框架返回数据库条目。如果该服务在本地而非服务器上正常运行，则在我看来数据库连接有问题，请尝试检查连接字符串，避免使用Windows Integrated Security连接数据库。
除此之外，这是我的有关托管Restful风格wcf服务的代码段。
服务器（wcf服务应用程序）

[OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    Product GetProduct(int ID);
    public Product GetProduct(int ID)
    {
        TestStoreEntities entities = new TestStoreEntities();
        return entities.Products.FirstOrDefault(x => x.Id == ID);
    }

配置。

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpsGetEnabled="true" httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <dataContractSerializer maxItemsInObjectGraph="2147483647" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior>
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <protocolMapping>
      <add binding="webHttpBinding" scheme="http" />
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

连接字符串。

<connectionStrings><add name="TestStoreEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=10.157.18.36;initial catalog=TestStore;persist security info=True;user id=sa;password=123456;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
</connectionStrings>

请随时告诉我是否有什么可以帮忙的。
