Python用转义的双引号解析JSON
考虑这个有效的json：
{"a": 1, "b": "{"c":2}"}
当我试图解析它时，Python的json模块会抛出 - 它看起来像"扔掉它：
json.loads('{"a": 1, "b": "{"c":2}"}')
Traceback (most recent call last):
File "", line 1, in
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
return _default_decoder.decode(s)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 365, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 381, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Expecting , delimiter: line 1 column 15 (char 14)
有没有什么办法在Python中解析这个，或者使用json模块或者像ujson这样的其他模块？
其实这与双引号的逃脱无关。 看我的测试：
>>> json.loads('{"a": 1, "b": "{"c":2}"}')
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/usr/lib/python3.4/json/__init__.py", line 318, in loads
return _default_decoder.decode(s)
File "/usr/lib/python3.4/json/decoder.py", line 343, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python3.4/json/decoder.py", line 359, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Expecting ',' delimiter: line 1 column 18 (char 17)
>>> json.loads('{"a": 1, "b": "{"c":2}"}')
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/usr/lib/python3.4/json/__init__.py", line 318, in loads
return _default_decoder.decode(s)
File "/usr/lib/python3.4/json/decoder.py", line 343, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python3.4/json/decoder.py", line 359, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Expecting ',' delimiter: line 1 column 18 (char 17)
>>> json.loads('{"a": 1, "b": {"c":2}}')
{'a': 1, 'b': {'c': 2}}
>>> json.loads('{"a": 1, "b": {"c":2}}')
{'a': 1, 'b': {'c': 2}}
>>>
在引用的字符串中，“ "与普通引号的处理方式相同：
>>> '{"a": 1, "b": "{"c":2}"}'
'{"a": 1, "b": "{"c":2}"}'
因此，您的字符串不是有效的JSON。
您还需要跳过反斜杠，以便将它们发送到loads 。 你可以通过dumps编码你想要的字典来看到这一点：
>>> json.dumps({"a": 1, "b": "{"c": 2}"})
'{"a": 1, "b": "{"c": 2}"}'
>>> json.loads('{"a": 1, "b": "{"c": 2}"}')
{u'a': 1, u'b': u'{"c": 2}'}
