Python BaseHTTPServer - 防止错误（"connection reset by peer," 等）破坏 curses 显示

Question

我有一个 Python 实现内置网络服务器的脚本：

class http_server(BaseHTTPRequestHandler):
    def log_message(self, format, *args):
      # prevent the BaseHTTPServer log messages, we use our own logging instead
      return
    def do_GET(self):
      log("responding to http request from %s: %s" % (self.client_address[0], self.path))
      text_string = "Hello World"
      self.send_response(200)
      self.send_header("Content-type", "text/plain")
      self.send_header("Content-Length", len(text_string))
      self.end_headers()
      self.wfile.write(text_string)

def start_server():
  try:
    httpd = SocketServer.TCPServer(("", 8888), http_server)
    httpd.serve_forever()
  except Exception as e:
      cleanup(None, None)
      print "Error starting internal http server: %s" % repr(e)
      sys.exit(1)

# main script
# does various things, initializes curses, etc.
start_server()

这工作正常，但问题是 python 脚本还在另一个线程中使用 curses 运行实现屏幕状态显示。当 HTTP 服务器中发生错误时（例如 "connection reset by peer" 等），指示所述错误的 python 回溯会散布在我漂亮的 curses 显示中。

我尝试在 BaseHTTPRequestHandler class 的 do_GET 部分周围添加 try...exception 块，但没有效果。

如何在这段代码中隐藏 Python 回溯消息？

Answer 1

尝试覆盖 BaseServer 的 handle_error 方法：

class MyServer(SocketServer.TCPServer):

    def handle_error(self, request, client_address):
        pass

然后在 start_server 函数中使用 MyServer。
