如何通过 Python Socket 发送原始 XML 而不是字节数据？

Question

Is there any method for Socket of Python to deliver XML instead of bytes. As the server side only recieves raw XML. I tried the code below but it raises attribute error, it asks for bytes instead of string. Any idea?

  import socket

  server_ip = "192.168.88.52"
  port = 2605

  socket_obj = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  socket_obj.settimeout(5.0)

  try:
      socket_obj.connect((server_ip, port, ))
      command = '<SERVICE ID="TA"><TRACKID_GET></TRACKID_GET></SERVICE>'

      socket_obj.send(command)
      print(f"Successfully send the command")

      data = socket_obj.recv(4096)
      print(f"Received Response: {data}")
  except socket.timeout as e:
      print(f"Response TimeOut: {e}")
      socket_obj.close()
  except Exception as e:
      print(f"Failed to connect to the P1 server: {e}")

There is no such thing as "raw XML" (except as an abstract concept).

There is also no such thing as sending "text" over the network (or writing it into a file for that matter).

Whatever you want to send through your socket will have to be encoded into bytes using some encoding. Just .encode() will default to UTF-8, which will probably do fine here (until it probably won't).

Also, you'll probably want .sendall() to ensure everything has been sent.
