无法建立连接,因为目标计算机主动拒绝它127.0.0.1

Question

我尝试使用WebRequest类连接到托管在不同服务器上的Web服务.Web服务返回一个字符串作为响应.这样做我得到一个错误:

"System.Net.Sockets.SocketException:无法建立连接,因为目标计算机主动拒绝它"

System.Net.WebException:无法连接到远程服务器---> System.Net.Sockets.SocketException:无法建立连接,因为目标计算机在System.Net.Sockets.Socket上主动拒绝它127.0.0.1:14012 System.Net.ServicePoint.ConnectSocketInternal上的.DoConnect(EndPoint endPointSnapshot,SocketAddress socketAddress)(布尔值connectFailure,套接字s4,套接字s6,套接字和套接字,IP地址和地址,ConnectSocketState状态,IAsyncResult asyncResult,异常和异常)---内部异常堆栈结束跟踪---在System.Net.HttpWebRequest.GetRequestStream(TransportContext&context)at System.Net.HttpWebRequest.GetRequestStream()at Limoallover.InsertSoapEnvelopeIntoWebRequestUS(XmlDocument soapEnvelopeXml,HttpWebRequest webRequest)at Limoallover.dawUpdateDriverStatus(String apiId,String apiKey,String idTrip ,String tripCode,String statusCode)at Limoallover.UpdateJobStatus(String Lat,String Lng,Int32 DriverID,Int32 nJobStatus,Int32 nJobId,String Company ID,String idTrip,String tripCode,String statusCode)

六天后,我找到了让我疯狂的答案!答案是在web.config文件中禁用代理:

<system.net>
  <defaultProxy> 
    <proxy usesystemdefault="False"/> 
  </defaultProxy>
</system.net>

异常消息表明您正在尝试连接到同一主机(127.0.0.1),而您声明您的服务器正在另一台主机上运行.除了明显的错误,如在网址中有"localhost",或者您可能想要检查您的DNS设置.
