I have a strange issue. I'm trying to get Apple Push Notifications working with Python. I can connect and send individual messages without a problem. The issues pop up when I start sending more than one message, but it's more bizarre than even that.
I'm testing with multiple devices... some iPhones and some iPod Touches. I can send multiple messages to the iPhones without a hitch, but if I have an iPod Touch device id in the list, any message that goes after will fail.
So if I send 4 messages in sequence like this:
1 - iPhone
2 - iPhone
3 - ipod Touch
4 - iPhone
1 and 2 will be delivered, 3 and 4 fail.
Using the same device ID's, if I move any of the iPod Touch device ID's to be the first message, all messages will fail. Likewise, if I only send to iPhones, all messages will succeed.
Here's the code I'm testing with, in it's current state, I would only get the first two messages, the last two will fail every time.
import struct, ssl, json, sys, time, socket, binascii
from optparse import OptionParser
class PushSender(object):
def __init__(self, host, cert, key):
self.apnhost = (host, 2195)
self.sock = ssl.wrap_socket(socket.socket(socket.AF_INET, socket.SOCK_STREAM),
keyfile = key,
certfile = cert,
do_handshake_on_connect=False)
self.sock.connect(self.apnhost)
while True:
try:
self.sock.do_handshake()
break
except ssl.SSLError, err:
if err.args[0] == ssl.SSL_ERROR_WANT_READ:
select.select([self.sock], [], [])
elif err.args[0] == ssl.SSL_ERROR_WANT_WRITE:
select.select([], [self.sock], [])
else:
raise
def send_message(self, token, message):
payload = {'aps':{'alert':message}}
token = binascii.unhexlify(token)
payloadstr = json.dumps(payload, separators=(',',':'))
payloadLen = len(payloadstr)
fmt = "!BH32sH%ds" % payloadLen
notification = struct.pack(fmt, 0, 32, token, payloadLen, payloadstr)
self.sock.write(notification)
self.sock.
def close(self):
self.sock.close()
def main():
parser = OptionParser()
parser.add_option("-c", "--certificate", dest="cert",
metavar="FILE",
help="Certificate file", )
parser.add_option("-p", "--privatekey", dest="key",
metavar="FILE",
help="Key file", )
parser.add_option("--host", help="apn host", dest='host')
(options, args) = parser.parse_args()
sender = PushSender(options.host, options.cert, options.key)
iphone1 = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
print 'Sending iPhone #1 a message.'
print sender.send_message(iphone1,'Hey iPhone #1.')
iphone2 = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
print 'Sending iPhone #2 a message.'
print sender.send_message(iphone2,'Hey iPhone #2.')
ipod1 = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
print 'Sending iPod #1 a message.'
print sender.send_message(ipod1,'Hey iPod #1.')
iphone3 = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
print 'Sending iPhone #3 a message.'
print sender.send_message(iphone3,'Hey iPhone #3.')
sender.close()
if __name__=="__main__":
main()
Any help would be appreciated...
