如下错误属于弱智错误，但是错的原因让我无语，所以记录一下 str2="{'card':6217001650004184441}" print(json.loads(str2))

Traceback (most recent call last):

File "G:/FastWorkStateServer/logs/redis_fabu.py", line 20, in <module>

print(json.loads(str2))

File "D:\python3.6.5\lib\json\__init__.py", line 354, in loads

return _default_decoder.decode(s)

File "D:\python3.6.5\lib\json\decoder.py", line 339, in decode

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

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

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

 

错误原因：字符串里用单引号来标识字符。

解决方法：将字符串里的单引号替换成双引号

import retest=re.sub('\'','\"',test)result=json.loads(test)result['data']'123'

 

对于带u'的字符串，u也要去掉：

c={u"test":124}d=re.sub("u'","\"",c)  json.loads(d)
