从“对等连接重置”中恢复； Indy TCP客户端

本文介绍了从“对等连接重置”中恢复； Indy TCP客户端的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在这种情况下我应该如何恢复？

How should I be recovering in this situation?

服务器崩溃，因此连接已异常关闭。对几乎所有内容的调用都会导致对等连接重置异常。我似乎已经通过在except块内的TIdTCPClient对象上调用Disconnect修复了该问题，但是它导致了一个最终异常，该消息带有相同的消息（这是我在第二个try-except块中捕获的）。

The server crashes, thus the connection has been abnormally closed. Calls to almost everything result in "Connection Reset By Peer" exceptions. I seem to have fixed it by calling Disconnect on the TIdTCPClient object inside the except block, but it results in one final exception with the same message (which I have caught in the second try-except block).

这与Indy10和Delphi XE2一起使用。

This is with Indy10 and Delphi XE2.

   try
      if not EcomSocket.Connected then EcomSocket.Connect();
    except
      on e: Exception do begin
        try
          EcomSocket.Disconnect();
        except
          MessageDlg('Connectivity to the server has been lost.', mtError, [mbOK], 0);
        end;
      end;
    end;

推荐答案

尝试一下：

try
  if not EcomSocket.Connected then EcomSocket.Connect();
except
  try
    EcomSocket.Disconnect(False);
  except
  end;
  if EcomSocket.IOHandler <> nil then EcomSocket.IOHandler.InputBuffer.Clear;
  MessageDlg('Connectivity to the server has been lost.', mtError, [mbOK], 0);
end;
