添加服务引用提供异常:无法连接到远程服务器

Question

从控制台应用程序客户端调用时,我的WCF服务返回结果.然而,它正在显示

例外:无法连接到远程服务器

实际错误:

无法调用该服务.可能的原因:服务离线或无法访问; 客户端配置与代理不匹配; 现有代理无效.有关更多详细信息,请参阅堆栈跟踪.您可以尝试通过启动新代理,还原到默认配置或刷新服务来进行恢复.

错误详情:

由于内部错误,服务器无法处理请求.有关错误的更多信息,请在服务器上启用IncludeExceptionDetailInFaults(来自ServiceBehaviorAttribute或配置行为),以便将异常信息发送回客户端,或者根据Microsoft .NET Framework SDK文档打开跟踪,检查服务器跟踪日志.

服务器堆栈跟踪:在System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood(消息回复,MessageFault错误,字符串操作,MessageVersion版本,FaultConverter faultConverter)处于System的System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime操作,ProxyRpc和rpc). ServiceModel.Channels.ServiceChannel.Call(String action,Boolean oneway,ProxyOperationRuntime operation,Object [] ins,Object [] outs,TimeSpan timeout)在System的System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall,ProxyOperationRuntime操作). ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage消息)

在[0]处重新抛出异常:在System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg,IMessage retMsg)处于IJiraService.GetProjects的System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData&msgData,Int32类型)处( )在JiraServiceClient.GetProjects()

请注意,当Fiddler运行时,该服务工作正常.但是,如果我关闭Fiddler,那么它显示异常:

这是Fiddler日志(当我得到数据时):

TTP/1.1 200连接成立日期:2015年8月6日星期四14:39:22 GMT代理连接:保持活动通过:1.1 localhost.localdomain

加密的HTTPS流量流经此CONNECT隧道.在Fiddler中启用了HTTPS解密,因此在此隧道中运行的解密会话将显示在"Web会话"列表中.

如上所述Fiddler日志是我必须在web.config文件中更改的东西,以使其工作？

从WCF测试客户端调用时.这是我尝试过的:

Web.config文件:

<?xml version="1.0"?>
  <configuration>
  <!--<system.net>
   <defaultProxy useDefaultCredentials="true" >
  </defaultProxy>
 </system.net>-->
<appSettings>

    </basicHttpBinding>
    </bindings>
   <client>
     <endpoint address="http://localhost:19065/JiraService.svc"  binding="basicHttpBinding"
        bindingConfiguration="BasicHttpBinding_IJiraService" contract="ServiceReference1.IJiraService"
       name="BasicHttpBinding_IJiraService" />
    </client>

     <serviceBehaviors>
       <behavior>
         <!-- 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"/>
   <!--

    Set to false before deployment to avoid disclosing web app folder information.
  -->
  <directoryBrowse enabled="true"/>
 </system.webServer>

</configuration>

这是我在我的代码中请求的方式:

public class Service : IService
{
    private string GetRestURL()
    {
        return System.Configuration.ConfigurationManager.AppSettings["resturl"];
    }

    private string GetUserName()
    {
        return System.Configuration.ConfigurationManager.AppSettings["MyUserName"];
    }

    private string GetPassword()
    {
        return System.Configuration.ConfigurationManager.AppSettings["MyPassword"];
    }

 public string method()
 {
       HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
        // HttpClient 


        request.ContentType = "application/json; charset=UTF-8";
        //request.ContentType = "text/xml; charset=UTF-8";
        /*request.Headers.Add("X-Atlassian-Token", "nocheck");
        request.UseDefaultCredentials = true;
        request.KeepAlive = true;*/
        request.Method = method;

        /*if (data != null)
        {
            using (StreamWriter writer = new StreamWriter(request.GetRequestStream(),Encoding.ASCII))
            {
                writer.Write(data);
            }
        }*/
        string base64Credentials = GetEncodedCredentials();
        request.Headers.Add("Authorization", "Basic " + base64Credentials);



     try
     {
        request.Headers.Add("Authorization", "Basic " + base64Credentials);

        response = request.GetResponse() as HttpWebResponse; //here its NULL

        if (response.StatusCode != HttpStatusCode.OK)
        {
                throw new Exception(String.Format("Server error (HTTP {0}:{1}).",response.StatusCode,response.StatusDescription));
        }
    }
    catch (Exception ex) //Here I'm getting exception
    {
        throw new Exception(ex.Message);
    }
 }

这是我的方法签名:

[ServiceContract]
public interface IService
{
    [OperationContract]
    List<ProjectDescription> GetProjects();
 }

注意:"方法"从"GetProjects"调用

这是我通过调用WCF测试客户端进行调试时得到的内部异常:

这是我内心异常

连接尝试失败,因为连接方在一段时间后没有正确响应,或者建立的连接失败,因为连接的主机无法响应165.254.xxx.xxx:443

注意:从控制台应用程序调试时没有调试异常.正如我所说,控制台应用程序工作正常,我能够从服务返回结果.

更新:当我在控制台应用程序中添加此服务作为"添加引用"时,它正常工作.但是,当我在同一个控制台应用程序中添加"添加服务引用"时,它显示同样的错误.我的网络阻止了什么吗？请帮忙.

怎么纠正这个？我还需要添加其他东西web.config吗？或者我是否需要在某个地方允许URL作为可信URL？
