尝试自托管，我收到错误 - wcf 服务主机找不到任何服务元数据.. 请检查元数据是否已启用 [英] Trying to self-host, I get error - wcf service host cannot find any service metadata .. please check if metadata is enabled

问题描述

我是 WCF 的新手，我已经阅读了标题与我的错误类似的问题的答案，但我仍然看不出哪里出了问题.

I am new to WCF and I've read answers to questions with titles similar to my error but I still cannot see what is wrong.

根据其他一些教程，我决定将我的合同和我的服务放在不同的项目中.最终，我想在 IIS 中托管它，但现在我只想启动 WCF 服务主机(和 WCF 测试客户端).

Following some other tutorials I decided to put my contract and my service in separate projects. Ultimately, I would like to host this in IIS but for now I just wanted to get the WCF Service Host to start (and WCF Test Client).

这是我服务项目中的app.config(我想知道这是否也需要在我的合同项目中??...):

Here is the app.config in my service project (would this need to be in my contract project too I wonder??...):

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="CBMI.TrimWCF.FileService"
               behaviorConfiguration="Metadata">
        <endpoint address="ws" 
                  binding="wsHttpBinding" 
                  contract="CBMI.TrimWCF.FileServiceContract.IFileService">
        </endpoint>
        <endpoint name="mex" 
                  address="mex" 
                  binding="mexHttpBinding" 
                  contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8081/TrimWCFfileService" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Metadata">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

这是我的服务项目中 FileService.cs 文件的开头:

Here is the beginning of the FileService.cs file in my services project:

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.IO;
using System.Diagnostics;                       // needed for writing to EventLog.
using System.Text;                              // needed for StringBuilder
using System.ComponentModel;
using System.Web;                               // need to target .Net Framework 4.0 for the    project (for HttpContext)

using TRIMSDK;                                  // for TRIM 6.2. 7.1 (the "COM" SDK)
using CBMI.TrimWCF.Utilities;                   // separate project for misc classes
using CBMI.TrimWCF.FileServiceContract;
namespace CBMI.TrimWCF.FileService
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class FileService : IFileService
{
    Database db;
    string g_EventSource = "CBMI-TrimBroker";
    string g_EventLog = "Application";

    public FileService()
    {

最后，这是我的合同项目中的一些 IFileService.cs 文件:

Finally, here is a bit of my IFileService.cs file in my contracts project:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace CBMI.TrimWCF.FileServiceContract
{
    [ServiceContract(Name = "IFileService", Namespace = "http://www.cbmiweb.com/TrimWCF/2011/11")]
    public interface IFileService
    {
        [OperationContract]
        string GetData(int value);

        [OperationContract]
        CompositeType GetDataUsingDataContract(CompositeType composite);

    [OperationContract]
    string DownloadFile(string trimURL
            , string TrimRecordNumber
            , string CallerPC
            , string RequestorID
            , out byte[] docContents
            , out string returnFiletype
            , out string returnFilename);
    [OperationContract]
    void DownloadFileCF(string trimURL
            , string TrimRecordNumber
            , string CallerPC = "not specified"
            , string RequestorID = "not specified");
    [OperationContract]
    string SearchCF(string trimURL
            , string CFSearchString
            , string CallerPC
            , string RequestorID);
    [OperationContract]
    string UploadFileCF(string trimURL
            , byte[] incomingArray
            , string fileName
            , string TrimRecordTypeName
            , string metaDataString);
    [OperationContract]
    string UpdateRecordCF(string trimURL
            , string TrimRecordNumber
            , string metaDataString);
}

[DataContract(Name = "WCFsample", Namespace = "http://www.cbmiweb.com/TrimWCF/2011/11 ")]
public class CompositeType
{
    bool boolValue = true;
    string stringValue = "Hello ";

    [DataMember]
    public bool BoolValue
    {
        get { return boolValue; }
        set { boolValue = value; }
    }

    [DataMember]
    public string StringValue
    {
        get { return stringValue; }
        set { stringValue = value; }
    }
}
}

推荐答案

您的服务的实际名称是 BMI.TrimWCF.FileService.FileService(命名空间 BMI.TrimWCF.FileServicecode>，类名 FileService).在 标记的 name 属性上，您只有 BMI.TrimWCF.FileService，因此 WCF 找不到您的服务的配置.请在配置上使用服务的完全限定名称，然后 WCF 将正确读取它.

The actual name of your service is BMI.TrimWCF.FileService.FileService (namespace BMI.TrimWCF.FileService, class name FileService). On the name attribute for the <service> tag you have only BMI.TrimWCF.FileService, so WCF can't find the configuration for your service. Please use the fully-qualified name of the service on the configuration, and WCF will then read it correctly.
