python - 无法捕捉泡菜错误

Question

我有一个线程不断等待通过套接字输入。它接收的东西很好，但是如果我尝试pickle.loads使用字符串，那么我会收到一个错误。这将是一件容易的事情，但这是它返回的错误：

Exception in thread Listening to <socket._socketobject object at 0x232cd00> at ('127.0.0.1', 48774):
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 505, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/home/[redacted]/Server.py", line 46, in Listen
    pickled = pickle.loads(data)
  File "/usr/lib/python2.7/pickle.py", line 1382, in loads
    return Unpickler(file).load()
  File "/usr/lib/python2.7/pickle.py", line 858, in load
    dispatch[key](self)
  File "/usr/lib/python2.7/pickle.py", line 958, in load_binfloat
    self.append(unpack('>d', self.read(8))[0])
error: unpack requires a string argument of length 8

我已经尝试并通过没有规范的简单try...except检查成功地捕捉到了这一点，但我不知道如何捕捉这个“错误”，因为pickle.struct.error它只适用于少数情况。

Answer 1

对，原来struct.error是没有被捕获的错误......
