Question

我有一个使用web.py的python服务器与Apple推送通知服务器进行通信，这些服务器经常遇到SSLEOFError。我试图处理这个错误，但我似乎无法在ssl模块或pyopenssl或_ssl中找到它。任何帮助处理此错误或可能防止它将不胜感激。这是堆栈跟踪：

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/web/application.py", line 239, in process
    return self.handle()
  File "/usr/lib/python2.7/dist-packages/web/application.py", line 230, in handle
    return self._delegate(fn, self.fvars, args)
  File "/usr/lib/python2.7/dist-packages/web/application.py", line 420, in _delegate
    return handle_class(cls)
  File "/usr/lib/python2.7/dist-packages/web/application.py", line 396, in handle_class
return tocall(*args)
  File "/home/ubuntu/mdm-server/server/API/api.py", line 189, in GET
    COMMAND_QUEUE.get_queue(sql)
  File "/home/ubuntu/mdm-server/server/queue.py", line 165, in get_queue
    self.send_apns(row['udid'], sql)
  File "/home/ubuntu/mdm-server/server/queue.py", line 219, in send_apns
    except ssl.SSLEOFError:
AttributeError: 'module' object has no attribute 'SSLEOFError'

编辑：这里是没有错误处理错误的堆栈跟踪。我现在意识到我应该只处理超级班ssl.SSLERROR而不是ssl.SSLEOFERROR而我会尝试这样做，但是对于为什么会发生这种情况的任何见解将会非常感激。< / p>

SSLError: [Errno 8] _ssl.c:510: EOF occurred in violation of protocol

Edit2：ssl.SSLError处理错误。

Edit3：我必须编辑APNSWrapper，以便在服务器设置部分的GitHub存储库中详细使用TLSv1。 Example iOS MDM Server

好吧，想通了。当APNs服务器无法与目标手机通信时，APNSWrapper会抛出此错误。（例如，手机已关闭或没有接收。）如果有其他人遇到此问题，则尝试/除了阻止ssl.SSLError的阻止将处理此异常。如果是这种情况，暂时停止对APN的另一次调用可能是一个好主意。

重新处理SSLEOFError处理
