Apple推送通知增強格式

Question

當有人使用增強版協議時，有人知道如何從Apple推送通知服務獲取錯誤響應嗎？

Answer 1

根據蘋果文檔如果我們使用增強推送協議的版本中，我們可以從信道錯誤響應，錯誤respose格式：

COMMAND（1個字節）| STATUS（1個字節）| ID（4 字節）

狀態：

0: 'No errors encountered' 
1: 'Processing error' 
2: 'Missing device token' 
3: 'Missing topic' 
4: 'Missing payload' 
5: 'Invalid token size' 
6: 'Invalid topic size' 
7: 'Invalid payload size' 
8: 'Invalid token' 
255: 'None (unknown)' 

此處示例代碼：

... 
socket = SSLSocket (
    socket.socket() 
    , ssl_version = ssl.PROTOCOL_SSLv3 
    , certfile 
) 

socket.connect(apnsHost, apnsPort) 

len_written = connectionContext.write(socket) 

errors = [] 

# Wait for input from socket 
inputready = select.select ([socket], [],[], 1)[0] 

if inputready: 
     replyBlock = channel.recv (6) 

     errors = [] #will be filled with error responses 
     while replyBlock: 
      #error-response packet 
      #COMMAND(1)|STATUS(1)|ID(4) 
      command, status, id = struct.unpack_from('!BBL', replyBlock) 

      if status != 0: 
       errors.append((command, status, id))     

      replyBlock = channel.recv (6)
