I write a fucntion to parse this message

def parse_multi_msg(msg):
  is_in_quotation = False
  aObjs = []
  sTemp = ""
  for c in msg:
    sTemp += c;

    if c == '"':
      if not is_in_quotation:
        is_in_quotation = True
      else:
        is_in_quotation= False


    if c == "}" and not is_in_quotation:
      aObjs.append(json.loads(sTemp));
      sTemp = "";

  return aObjs

Maybe you should delimit the messages you send so it is easy to split them up - in this case you could add a \n, obviously the delimiter mustn't happen within the message. Another way would be to prefix each message with its length in also a clearly-delimited way, then the receiver reads the length then that number of bytes and parses it.
