python json.loads兼容单引号数据的方法


						Python的json模块解析单引号数据会报错，示例如下





>>> import json

>>> data = "{'field1': 0, 'field2': 'hehehehe', 'field3': 'hahaha'}"

>>> json.loads(data)







Traceback (most recent call last): 

File “”, line 1, in 

File “/usr/lib/python3.5/json/init.py”, line 319, in loads 

return _default_decoder.decode(s) 

File “/usr/lib/python3.5/json/decoder.py”, line 339, in decode 

obj, end = self.raw_decode(s, idx=_w(s, 0).end()) 

File “/usr/lib/python3.5/json/decoder.py”, line 355, in raw_decode 

obj, end = self.scan_once(s, idx) 

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)





摸索的解决办法如下





>>> data = json.dumps(eval(data))

>>> print(data)







{“field3”: “hahaha”, “field2”: “hehehehe”, “field1”: 0}



处理后正确解析





>>> print(json.loads(data))







{‘field3': ‘hahaha', ‘field2': ‘hehehehe', ‘field1': 0}
