Question

我创建了一个WCF服务来上传文件，WCF服务托管在Windows IIS上。我也有一个客户端通过HTTPS使用这个WCF服务，目前客户端和服务在同一台机器上。代码如下所示：

IService1.cs：

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

namespace WcfService1
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {


        [OperationContract]
        void UploadFile(RemoteFileInfo request);


        // TODO: Add your service operations here
    }


    [MessageContract]
    public class RemoteFileInfo : IDisposable
    {
        [MessageHeader(MustUnderstand = true)]
        public string FilePath;

        /*
        [MessageHeader(MustUnderstand = true)]
        public string DestinationDirectory;
        */

        [MessageBodyMember(Order = 1)]
        public System.IO.Stream FileByteStream;

        public void Dispose()
        {
            if (FileByteStream != null)
            {
                FileByteStream.Close();
                FileByteStream = null;
            }
        }
    }
}

Service1.cvs.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.IO;
using System.ServiceModel.Web;
using System.Diagnostics;

namespace WcfService1
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select Service1.svc or Service1.svc.cs at the Solution Explorer and start debugging.
    public class Service1 : IService1
    {

        public void UploadFile(RemoteFileInfo request)
        {
            FileStream targetStream = null;
            Stream sourceStream = request.FileByteStream;

            //string destinationDirectory = request.DestinationDirectory;
            Console.WriteLine(request.FilePath);
            string fileName = Path.GetFileName(request.FilePath);

            string filePath = Path.Combine("C:\\upload", fileName);

            using (targetStream = new FileStream(filePath, FileMode.Create,
                                  FileAccess.Write, FileShare.None))
            {


                const int bufferLen = 65000;
                byte[] buffer = new byte[bufferLen];
                int count = 0;
                while ((count = sourceStream.Read(buffer, 0, bufferLen)) > 0)
                {

                    targetStream.Write(buffer, 0, count);
                }
                targetStream.Close();
                sourceStream.Close();
            }
        }


    }
}

的web.config：

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

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation targetFramework="4.5" />
    <httpRuntime targetFramework="4.5"/>

          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <!--
        To browse web app root directory during debugging, set the value below to true.
        Set to false before deployment to avoid disclosing web app folder information.
      -->
    <directoryBrowse enabled="true"/>
  </system.webServer>

</configuration>

客户代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ClientApp.ServiceReference1;

namespace ClientApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Service1Client client = new Service1Client();

            string FilePath1 = "C:\\Users\\user1\\Desktop\\data.csv";
            System.IO.FileStream stream1 =
            new System.IO.FileStream("C:\\Users\\user1\\Desktop\\data.csv",
            System.IO.FileMode.Open, System.IO.FileAccess.Read);

            string dest = "C:\\upload";
            client.UploadFile(FilePath1, stream1);
            client.Close();

        }
    }
}

此客户端代码抛出异常＆＃34; client.UploadFile（FilePath1，stream1）; ＆＃34; ：

An unhandled exception of type 'System.ServiceModel.EndpointNotFoundException' occurred in mscorlib.dll

Additional information: There was no endpoint listening at http://localhost:53673/Service1.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

但是，如果我启动浏览器访问该站点，我可以成功访问Service1.svc（这意味着我配置了IIS并正确地将服务发布到IIS），如下面的屏幕截图所示：

我想知道问题出在哪里？提前谢谢！

编辑：

orignal客户端的App.config如下：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService1" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:53673/Service1.svc" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"
                name="BasicHttpBinding_IService1" />
        </client>
    </system.serviceModel>
</configuration>

根据建议，我将其更改为：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpsBinding>
                <binding name="BasicHttpsBinding_IService1" />
            </basicHttpsBinding>
        </bindings>
        <client>
            <endpoint address="https://localhost:53673/Service1.svc" binding="basicHttpsBinding"
                bindingConfiguration="BasicHttpsBinding_IService1" contract="ServiceReference1.IService1"
                name="BasicHttpsBinding_IService1" />
        </client>
    </system.serviceModel>
</configuration>

现在，我又遇到了另一个错误：

An unhandled exception of type 'System.ServiceModel.CommunicationException' occurred in mscorlib.dll

Additional information: An error occurred while making the HTTP request to https://localhost:53673/Service1.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.

如果我可以从浏览器启动网站，我认为证书不存在问题。另外，我使用自签名证书，客户端和服务器在同一台机器上。我在想，如果我不能直接更改客户端的app.config，那么服务的配置有问题吗？我注意到每次在客户端服务引用中更新服务时，http绑定都会出现在app.config中。我想知道处理它的正确方法是什么？

Answer 1

将客户端app.config文件更改为指向正确的地址。它目前指向：

<endpoint address="https://localhost:53673/Service1.svc" binding="basicHttpsBinding"

将地址部分更改为屏幕截图中屏蔽的部分。
