Python使用转义的双引号解析JSON [英] Python parsing JSON with escaped double quotes

问题描述

考虑此有效的json:

Consider this valid json:

{"a": 1, "b": "{\"c\":2}"}

当我尝试解析它时，Python的json模块会抛出-好像\"正在抛出它:

Python's json module throws when I try to parse it - it looks like the \" is throwing it off:

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)

是否可以使用json模块或诸如ujson之类的其他模块在Python中解析此内容?

Is there any way to parse this in Python, either using the json module or some other module like ujson?

推荐答案

实际上，转义的双引号无关紧要.查看我的测试:

Actually it doesn't matter with escaped double quotes. See my test:

>>> 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}}
