如何在Python中实现GCM HTTP服务器，同时避免我的服务器的IP被Google列入黑名单？

I'm using Apache, WSGI (mod_wsgi) and Python, to implement a GCM HTTP server as describe in the Android Developer website:

我正在使用Apache,WSGI(mod_wsgi)和Python来实现GCM HTTP服务器,如Android Developer网站所述:

developer.android.com/google/gcm/server.html

At first the code I've implemented on the server side to handle message sending to GCM was as the following:

首先,我在服务器端实现的代码处理向GCM发送消息的代码如下:

def send_to_gcm(data):
   url = 'https://android.googleapis.com/gcm/send'
   no = 1
   while True:
     try:
        request = Request(url=url, data=json.dumps(data))
        request.add_header('Authorization','key=AIzXXX')
        request.add_header('Content-Type', 'application/json')
        res = urlopen(request)

        if res.getcode() == 200: return
    except Exception: pass

    no += 1

    #Discard the message
    if no == 16: return 

    #Exponential backoff
    tts = randint(2**(no-1), (2**no) -1)
    sleep(tts)

data = dict(registration_id=[regid], data=dict(mymessage=themessage))
thread = Thread(target=send_to_gcm, args=(data,))
thread.start()

After a while (about a day) GCM stopped to accept the messages sent by the Server. So I started to dig here and there in the documentation of GCM and I found an important part of the specification I missed before:

过了一会儿(大约一天),GCM停止接受服务器发送的消息。所以我开始在GCM的文档中随处挖掘,我发现了之前错过的规范的一个重要部分:

developer.android.com/google/gcm/http.html#response

"Honor the Retry-After header if it's included in the response from the GCM server. ... Senders that cause problems risk being blacklisted. ... Happens when the HTTP status code is between 501 and 599, or when the error field of a JSON object in the results array is Unavailable."

“如果它包含在来自GCM服务器的响应中,请尊重Retry-After标头。...导致问题的发件人可能会被列入黑名单。...当HTTP状态代码介于501和599之间时,或者当错误字段出现时结果数组中的JSON对象不可用。“

So i patched my server code as follow:

所以我修改了我的服务器代码如下:

def send_to_gcm(data, environ):
   url = 'https://android.googleapis.com/gcm/send'
   no = 1
   while True:
      try:
         request = Request(url=url, data=json.dumps(data))
         request.add_header('Authorization','key=AIzXXX')
         request.add_header('Content-Type', 'application/json')
         res = urlopen(request)

         if res.getcode() == 200: return
      except HTTPError as error:

         if error.headers.has_key('Retry-After'):
            try: tts = int(response_headers['Retry-After'])
            except ValueError:
               until = datetime.strptime(response_headers, '%a, %d %b %Y %H:%M:%S GMT')
               diff = until - datetime.now()
               tts = int(diff.total_seconds()) +1
            sleep(tts)

      no += 1

      #Discard the message
      if no == 16: return 

      #Exponential backoff
      tts = randint(2**(no-1), (2**no) -1)
      sleep(tts)

But actually it's likely my server has been blacklisted and for any request sent I receive a 401 status code and an "Unauthorized" error message. Here my questions:

但实际上我的服务器可能已被列入黑名单,并且对于发送的任何请求,我收到401状态代码和“未授权”错误消息。在这里我的问题:

Is there something wrong in my latest server implementation?
Will the static IP address of my server be unbanned and if yes when?

我最新的服务器实现有什么问题吗?我的服务器的静态IP地址是否会被取消,如果是的话?
