Question

我有一个应用已经在应用商店，我还有一台服务器向iphone发送推送通知。

我的问题是有时，通知没有到达iphone，这只发生在2或3小时后没有与苹果推送服务器进行apns通信之后，但是在超时后，它将再次开始工作。它真的是随机的。

起初我虽然问题是超时，但我试图打印出我的ssl_wrap.send（）函数的返回值，它确实返回了应该发送的字符串的长度，这意味着，Apple APNS收到了我所有的json字符串。它只是不将它们广播到客户端电话。

我需要继续触发apns服务器直到它超时才能再次推送通知，这是不对的。

有什么想法吗？

class PushSender:
def __init__(self):     
    _sock = socket.socket( socket.AF_INET, socket.SOCK_STREAM )
    _sock.settimeout(2)
    self.ssl_sock = ssl.wrap_socket( _sock, certfile = theCertfile )
    self.ssl_sock.settimeout(1) 
    self.ssl_sock.connect( theHost )
    self.counter = 0
    self.lastPush = time()

def reset(self):
    Log("Reset APNS");
    self.ssl_sock.close()
    _sock = socket.socket( socket.AF_INET, socket.SOCK_STREAM )
    _sock.settimeout(2)
    self.ssl_sock = ssl.wrap_socket( _sock, certfile = theCertfile )
    self.ssl_sock.settimeout(1)
    self.ssl_sock.connect( theHost )
    self.counter = self.counter + 1;
    self.lastPush = time()

def send(self,token, message, badge, sound):
    #Log("INIT APNS")
    payload = {}
    aps = {}
    aps["alert"] = str(message)
    aps["badge"] = badge
    aps["sound"] = str(sound)

    payload["aps"] = aps

    if time() - self.lastPush> 60*30 : # 30 minutes idle reconnect
        self.reset()
    try:
        #Log("Making Message APNS")
        tokenh = binascii.unhexlify(token)
        payloadstr = json.dumps(payload, separators=(',',':'))
        payloadLen = len(payloadstr)
        fmt = "!cH32sH%ds" % payloadLen
        command = '\x00'
        msg = struct.pack(fmt, command, 32, tokenh, payloadLen, payloadstr)
    except:
        Log("APNS Data Error " +token+" " +message);
        return;     
    try:
        #Log(msg)
        sent = 0;
        while sent < len(msg):
            msg2 = msg[sent:];
            justSent = self.ssl_sock.write( msg2 )
            #Log(str(len(msg)) + " " + str(justSent))
            sent += justSent
            if justSent==0 :
                raise socket.error(0,"Send failed")
    except socket.error, err:
        Log( "APNS Error: "+str(self.counter)+" "+ str(err) )
        self.reset()
        if self.counter<=2 : self.send(token,message,badge,sound)
    Log( "APNS DONE"+ str(self.counter))
    self.counter = 0;
    self.lastPush = time()

Apple Push APNS有时候没有到达
