Python 无法pickle ZabbixAPI 类实例

Question

我无法使用以下代码来pickle pyzabbix.ZabbixAPI 类实例:

from pyzabbix import ZabbixAPI
from pickle import dumps

api = ZabbixAPI('http://platform.autuitive.com/monitoring/')

print dumps(api)

它会导致以下错误:

Traceback (most recent call last):
  File "zabbix_test.py", line 8, in <module>
    print dumps(api)
  File "/usr/lib/python2.7/pickle.py", line 1374, in dumps
    Pickler(file, protocol).dump(obj)
  File "/usr/lib/python2.7/pickle.py", line 224, in dump
    self.save(obj)
  File "/usr/lib/python2.7/pickle.py", line 306, in save
    rv = reduce(self.proto)
  File "/usr/lib/python2.7/copy_reg.py", line 84, in _reduce_ex
    dict = getstate()
TypeError: 'ZabbixAPIObjectClass' object is not callable

Answer 1

嗯，在 documentation它说:

instances of such classes whose __dict__ or the result of calling __getstate__() is picklable (see section The pickle protocol for details).

而且这个类似乎不是一个。如果您确实需要这样做，请考虑编写自己的酸洗例程。
