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}
