WCF 服务在本地而非服务器 IIS 上工作以获取功能

Question

我有一个基本的 WCF 服务位于服务器 IIS 上，SQL 数据库也位于它上面。

当我在本地运行它时，它工作正常，我的所有服务功能都可以工作，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 时

如果我只是转到起始页面，我会找不到终点，这在我的本地是一样的。

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，但我已设法将其解决到表明我的服务没有终点的地方。

<?xml version="1.0" encoding="utf-8"?>

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

          <serviceDebug includeExceptionDetailInFaults="true" />

        </behavior>

    </behaviors>

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

我在微软网站上找到的配置尝试了几个不同的选项，但没有帮助。

谢谢。

我注意到您使用 ORM 框架来返回数据库条目。如果服务在本地而不是服务器上正常工作，在我看来是数据库连接有问题，尝试检查连接字符串，避免使用windows集成安全连接数据库。
此外，这是我关于托管 Restful 风格 wcf 服务的代码 sn-ps。
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>

如果有什么我可以帮忙的，请随时告诉我。
