Unpickle Python 类
我在尝试解开此类的子类时遇到问题。当我拆开它时，东西不在那里。什么给？ 班级帐号：
def __init__(self, server, port, smtp_server, smtp_port):
self.server = server
self.port = port
self.smtp_server = smtp_server
self.smtp_port = smtp_port
self.save()
def save(self):
#save account for later loading
self.name = tkFileDialog.asksaveasfilename(title = "Save as..")
pickle.dump(self, open(self.name, "wr"))
I have a problem trying to unpickle subclasses of this class. When I unpickle it, the stuff isn't there. What gives?
class Account:
def __init__(self, server, port, smtp_server, smtp_port):
self.server = server
self.port = port
self.smtp_server = smtp_server
self.smtp_port = smtp_port
self.save()
def save(self):
#save account for later loading
self.name = tkFileDialog.asksaveasfilename(title = "Save as..")
pickle.dump(self, open(self.name, "wr"))

你的类继承
object吗？无论哪种方式，您都可以通过覆盖
__getstate__来指定要腌制的内容。否则，如果您继承object，它通常应该复制__dict__。Does your class inherit
object?Either way, you can specify what you want to pickle by overwriting
__getstate__. Otherwise it should normally copy__dict__if you're inheritingobject.所以，这就是我刚刚想到的方法——我将丑陋的泡菜东西（参见评论）移到了 unpickling 类中，导入了我正在 pickle 的类，看起来它是有效的。
So, Here's how I just figured it out- i moved the ugly pickle stuff (see comment) to the unpickling class, imported the classes I was pickling, and it seems like it works.
