引用我创建的 WCF 服务时出错

如何解决引用我创建的 WCF 服务时出错

我对 WCF 比较陌生，所以我在 web.config 方面遇到了困难。

我在 IIS10 上创建了 WCF 服务。这是我的 web.config：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection,EntityFramework,Version=6.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    <!-- For more information on Entity Framework configuration,visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
  </configSections>
  <system.web>
    <customErrors mode="Off" />
    <compilation targetFramework="4.0" debug="true">

        <add assembly="System.Data.Entity,Version=4.0.0.0,PublicKeyToken=b77a5c561934e089" />
      </assemblies>
    </compilation>
    <caching>
      <outputCacheSettings>
        <outputCacheProfiles>
          <add name="DefaultCache" duration="60" varyByParam="none" />
        </outputCacheProfiles>

  </system.web>

  <system.serviceModel>
    <services>
      <service name="FileStorageService.FileService">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttpBindingConfiguration" contract="FileStorageService.IFileService" />

        <!--<endpoint address="mex"  
                  binding="mexHttpsBinding"  
                  contract="IMetadataExchange" />-->
      </service>
    </services>

    <bindings>
      <basicHttpBinding>
        <binding name="basicHttpBindingConfiguration">
          <security mode="Transport">
            <transport clientCredentialType="Basic" proxyCredentialType="None" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

          <serviceMetadata httpsGetEnabled="true" httpGetEnabled="false" />
          <!-- 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="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>


  <system.webServer>
    <httpErrors errorMode="Detailed" />
    <modules runAllManagedModulesForAllRequests="true" />

    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices,EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
</configuration>

我可以引用 api，但是当我尝试使用它时收到此消息：

服务器堆栈跟踪：在 System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood（消息 回复，MessageFault 故障，字符串操作，MessageVersion 版本， FaultConverter faultConverter) 在 System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime 操作，ProxyRpc& rpc) 在 System.ServiceModel.Channels.ServiceChannel.Call（字符串动作， Boolean oneway,ProxyOperationRuntime 操作,Object[] ins,Object[] outs,TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall、ProxyOperationRuntime 操作）在 System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage 留言）

我的代码：

public static Status DownloadPpsTransactionFile(FileParms fileParms)
{
  var client = new FileServiceClient();

  try
  {
    var downloadstatus = new Status();
    downloadstatus.ProgramSendType = fileParms.SendGet;

    client.ClientCredentials.UserName.UserName = "xxxxxx";
    client.ClientCredentials.UserName.Password = "xxxxxxxxxxx";
    var trucks = fileParms.Trucks.Split(Convert.ToChar(","));

    foreach (var truck in trucks)
    {
      int trk;
      if (!int.TryParse(truck,out trk))
      {
        continue;
      }

      var downloadrequest = new DownloadFileRequest();
      downloadrequest.CompanyCode = fileParms.CompanyCode;
      downloadrequest.FileType = 1;
      downloadrequest.TruckNumber = trk;
      DownloadFileResponse download;

      do
      {
        download = client.DownloadPpsTransactionFile(downloadrequest);

当我调用 wfc 方法时，它在最后一行失败。我似乎无法让 IIS 设置和 web.config 正常工作。

我在 IIS 上的设置：

我做错了什么？

客户端配置

<?xml version="1.0"?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IFileService">
          <security mode="Transport">
            <transport clientCredentialType="Basic" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://SOMEDOMAIN.COM/api/fileservice/FileService.svc"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IFileService"
        contract="MyFileServiceReference.IFileService" name="BasicHttpBinding_IFileService" />
    </client>
  </system.serviceModel>

</configuration>

附加信息

我在事件查看器中找到了这个。我目前正在研究它以了解其含义。

FailedRequestTracing 模块未能将缓冲事件写入日志 匹配失败定义的请求的文件。不会有日志 直到此条件得到纠正为止。问题发生在 在过去 5 分钟内至少 1 次。数据是错误。

解决方法

这不是我的答案，但我不能将其作为评论发布。这是显示异常的更简洁的方式，它为您提供了 D:\Source\Sub\Web Projects\WebStorageApps\PpsTransactionFile\download\DownloadFile.cs:line 155 中的确切行号。它还表明异常已rethrown 暗示故障已被理解，因此您可以在那里开始调查：

Server stack trace:

Exception rethrown at [0]:

at PpsTransactionFile.download.DownloadFile.DownloadPpsZipFile(FileParms fileParms)
in D:\Source\Sub\Web Projects\WebStorageApps\PpsTransactionFile\download\DownloadFile.cs:line 155

也可能只是一个错字，因为我注意到您在客户端端点配置中拼错了：<endpoint address="https://SOMEDOMIAN.COM ...，我想它应该是 <endpoint address="https://SOMEDOMAIN.COM...（注意“IA”而不是“AI”在域中）。

,

我无法将其作为评论发布，但我建议您在堆栈跟踪中找到异常消息。它可能会说明未对响应进行反序列化的原因。

如果这没有帮助，我会尝试使用 Wireshark 或日志代理来跟踪并查看哪些服务器回复了您的请求。

您似乎一直在遵循本指南：

https://docs.microsoft.com/en-us/dotnet/framework/wcf/feature-details/how-to-configure-an-iis-hosted-wcf-service-with-ssl

如果您按照他们的示例进行设置，您的代码是否有效？

</configuration>

鉴于错误：

FailedRequestTracing 模块未能将缓冲事件写入日志 匹配失败定义的请求的文件。不会有日志 直到此条件得到纠正为止。问题发生在 在过去 5 分钟内至少 1 次。数据是错误。

在此处查看配置：

https://docs.microsoft.com/en-us/iis/troubleshoot/using-failed-request-tracing/troubleshooting-failed-requests-using-tracing-in-iis-85

我还建议您从简单开始：创建一个可以工作的基本 WCF Web HTTP 服务，然后进行修改。如果您还没有尝试过，这可能会容易得多。

控制台示例：

Service.cs：

using System;
using System.Collections.Generic;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.ServiceModel.Web;
using System.Text;

namespace Microsoft.ServiceModel.Samples.BasicWebProgramming
{
    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        [WebGet]
        string EchoWithGet(string s);

        [OperationContract]
        [WebInvoke]
        string EchoWithPost(string s);
    }
    public class Service : IService
    {
        public string EchoWithGet(string s)
        {
            return "You said " + s;
        }

        public string EchoWithPost(string s)
        {
            return "You said " + s;
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            WebServiceHost host = new WebServiceHost(typeof(Service),new Uri("http://localhost:8000/"));
            try
            {
                ServiceEndpoint ep = host.AddServiceEndpoint(typeof(IService),new WebHttpBinding(),"");
                host.Open();
                using (ChannelFactory<IService> cf = new ChannelFactory<IService>(new WebHttpBinding(),"http://localhost:8000"))
                {
                    cf.Endpoint.Behaviors.Add(new WebHttpBehavior());

                    IService channel = cf.CreateChannel();

                    string s;

                    Console.WriteLine("Calling EchoWithGet via HTTP GET: ");
                    s = channel.EchoWithGet("Hello,world");
                    Console.WriteLine("   Output: {0}",s);

                    Console.WriteLine("");
                    Console.WriteLine("This can also be accomplished by navigating to");
                    Console.WriteLine("http://localhost:8000/EchoWithGet?s=Hello,world!");
                    Console.WriteLine("in a web browser while this sample is running.");

                    Console.WriteLine("");

                    Console.WriteLine("Calling EchoWithPost via HTTP POST: ");
                    s = channel.EchoWithPost("Hello,s);
                    Console.WriteLine("");
                }

                Console.WriteLine("Press <ENTER> to terminate");
                Console.ReadLine();

                host.Close();
            }
            catch (CommunicationException cex)
            {
                Console.WriteLine("An exception occurred: {0}",cex.Message);
                host.Abort();
            }
        }
    }
}
