移植的Node.js腳本到Python

Question

我想這個端口腳本Node.js加載到超過控制天空盒成Python，https://github.com/dalhundal/sky-remote/blob/master/sky-remote.js

我已經經歷了，做我能做的最好的，代碼如下;

import time, math, socket, struct, time 
from array import array 

    #sky q port 5900 

    class remote: 
     commands={"power": 0, "select": 1, "backup": 2, "dismiss": 2, "channelup": 6, "channeldown": 7, "interactive": 8, "sidebar": 8, "help": 9, "services": 10, "search": 10, "tvguide": 11, "home": 11, "i": 14, "text": 15, "up": 16, "down": 17, "left": 18, "right": 19, "red": 32, "green": 33, "yellow": 34, "blue": 35, 0: 48, 1: 49, 2: 50, 3: 51, 4: 52, 5: 53, 6: 54, 7: 55, 8: 56, 9: 57, "play": 64, "pause": 65, "stop": 66, "record": 67, "fastforward": 69, "rewind": 71, "boxoffice": 240, "sky": 241} 
     connectTimeout = 1000; 

     def __init__(self, ip, port=49160): 
      self.ip=ip 
      self.port=port 

     def showCommands(self): 
      for command, value in self.commands.iteritems(): 
       print str(command)+ " : "+str(value) 

     def getCommand(self, code): 
      try: 
       return self.commands[code] 
      except: 
       print "Error: command '"+code+"' is not valid" 
       return False 

     def press (self, sequence): 
      if isinstance(sequence, list): 
       for item in sequence: 
        toSend=self.getCommand(item) 
        if toSend: 
         self.sendCommand(toSend) 
         time.sleep(0.5) 

      else: 
       toSend=self.getCommand(sequence) 
       if toSend: 
        self.sendCommand(toSend)  

     def sendCommand(self, code): 
      commandBytes = array('l', [4,1,0,0,0,0, int(math.floor(224 + (code/16))), code % 16]) 

      try: 
       client=socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
      except socket.error, msg: 
       print 'Failed to create socket. Error code: ' + str(msg[0]) + ' , Error message : ' + msg[1] 
       return 

      try: 
       client.connect((self.ip, self.port)) 
      except: 
       print "Failed to connect to client" 
       return 

      l=12 
      timeout=time.time()+self.connectTimeout 

      while 1: 
       data=client.recv(1024) 
       data=data 

       if len(data)<24: 
        client.sendall(data[0:l]) 
        l=1 
       else: 
        client.sendall(buffer(commandBytes)) 
        commandBytes[1]=0 
        client.sendall(buffer(commandBytes)) 
        client.close() 
        break 

       if time.time() > timeout: 
        print "timeout error" 
        break 

我認爲問題是我如何形成緩衝區？我不完全確定，因爲這是我第一次處理緩衝區。 在閱讀了關於新Buffer的Node.js文檔之後，它看起來像創建了一個Octets數組，而我所擁有的是一個int數組，我可能是錯誤的，但Octet是8位，而int是4bits，已經嘗試將數組更改爲long和double，但是這似乎並不能解決問題

Answer 1

已經有時間快速瞭解Node.js如何處理緩衝區和緩衝區，並且它看起來像是什麼我認爲是對的。

變化;

commandBytes = array('l', [4,1,0,0,0,0, int(math.floor(224 + (code/16))), code % 16]) 

to;

commandBytes = bytearray([4,1,0,0,0,0, int(math.floor(224 + (code/16))), code % 16]) 

此外，只是通過bytearray;

client.sendall(commandBytes) 

而不是;

client.sendall(buffer(commandBytes))
