问题描述:
在导入Python json包,调用/dumps函数时,可能会遇到TypeError: Object of type xxx is not JSON serializable错误,也就是无法序列化某些对象格式。
解决办法:
默认的编码函数很多数据类型都不能编码,自定义序列化,因此可以自己写一个Myencoder去继承,具体如下:
class MyEncoder():
def default(self, obj):
if isinstance(obj, ):
return int(obj)
elif isinstance(obj, ):
return float(obj)
elif isinstance(obj, ):
return ()
else:
return super(MyEncoder, self).default(obj)
然后在调用/dumps时,指定使用自定义序列化方法
(data, cls=MyEncoder)
dict to json
def dict_to_json(dict_obj,name, Mycls = None):
js_obj = (dict_obj, cls = Mycls, indent=4)
with open(name, 'w') as file_obj:
file_obj.write(js_obj)
json to dict
def json_to_dict(filepath, Mycls = None):
with open(filepath,'r') as js_obj:
dict_obj = (js_obj, cls = Mycls)
return dict_obj
