问题描述
我在以下字符串中有一个字符串
I have a string in the following strings
json_string = '{u"favorited": false, u"contributors": null}'
json_string1 = '{"favorited": false, "contributors": null}'
以下json加载工作正常.
The following json load works fine.
json.loads(json_string1 )
但是,以下json加载给我值错误,该如何解决?
But, the following json load give me value error, how to fix this?
json.loads(json_string)
ValueError: Expecting property name: line 1 column 2 (char 1)
推荐答案
使用json.dumps
将Python字典转换为字符串,而不是str
.然后,您可以期望json.loads
可以正常工作:
Use json.dumps
to convert a Python dictionary to a string, not str
. Then you can expect json.loads
to work:
不正确:
>>> D = {u"favorited": False, u"contributors": None}
>>> s = str(D)
>>> s
"{u'favorited': False, u'contributors': None}"
>>> json.loads(s)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\dev\Python27\lib\json\__init__.py", line 339, in loads
return _default_decoder.decode(s)
File "D:\dev\Python27\lib\json\decoder.py", line 364, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "D:\dev\Python27\lib\json\decoder.py", line 380, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)
正确:
>>> D = {u"favorited": False, u"contributors": None}
>>> s = json.dumps(D)
>>> s
'{"favorited": false, "contributors": null}'
>>> json.loads(s)
{u'favorited': False, u'contributors': None}
