How to make a JSON object serializable
本问题已经有最佳答案，请猛点这里访问。
有没有一种方法可以在不使用自定义编码器的情况下序列化Python类？我尝试过以下方法，但我得到了错误：typeerror:hello不是JSON可序列化的，这很奇怪，因为"hello"是一个字符串。
1 2 3 4 5 6 7 8 9 10 11 | class MyObj(object): def __init__(self, address): self.address = address def __repr__(self): return self.address x = MyObj("hello") print json.dumps(x) |
输出应该简单
1 | "hello" |
杰森皮克怎么样？
jsonpickle is a Python library for serialization and deserialization
of complex Python objects to and from JSON.
1 2 3 4 5 6 7 8 9 | >>> class MyObj(object): ... def __init__(self, address): ... self.address = address ... def __repr__(self): ... return self.address ... >>> x = MyObj("hello") >>> jsonpickle.encode(x) '{"py/object":"__main__.MyObj","address":"hello"}' |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | import json class MyObj(object): def __init__(self, address): self.address = address def __repr__(self): return self.address def serialize(self, values_only = False): if values_only: return self.__dict__.values() return self.__dict__ x = MyObj("hello") print json.dumps(x.serialize()) print json.dumps(x.serialize(True)) |
输出
1 2 3 | >>> {"address":"hello"} ["hello"] |
