当使用增强版协议时,有人知道如何从Apple推送通知服务获得错误响应吗?
答案 0 :(得分:1)
根据Apple文档,如果我们使用增强版Push协议,我们可以从频道,错误设置格式获得错误响应:
COMMAND(1字节)| STATUS(1字节)| ID(4 字节)
状态:
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)'
这里是示例代码:
...
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)
