如果字符串有“\r”，Python 中的 json.loads(jsonstring) 会失败。即回车符
当我尝试时，我得到一个 JSON 字符串，该字符串在某处有一个 "\r" 字符，例如 "{"data":"foo \r\n bar"}"解析它会抛出ValueError。
>>> j="""{"data":"foo \r\n bar"}"""
>>> import json
>>> f=json.loads(j)
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
f=json.loads(j)
File "C:\Python27\lib\json\__init__.py", line 326, in loads
return _default_decoder.decode(s)
File "C:\Python27\lib\json\decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Python27\lib\json\decoder.py", line 382, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Invalid control character at: line 1 column 13 (char 13)
>>> j[13]
'\r'
"\r" 是 Python 字符串中完全合法的字符。
如何解析这个 JSON 字符串，以便
>>> dct = somehow_parse_json(j)
>>> dct['data']
'foo \r\n bar'
我可以轻松地找到并弹出回车符，但我希望它们可以被保存。
I am getting a JSON string which has a "\r" character somewhere e.g. "{"data":"foo \r\n bar"}" when I try to parse it throws ValueError.
>>> j="""{"data":"foo \r\n bar"}"""
>>> import json
>>> f=json.loads(j)
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
f=json.loads(j)
File "C:\Python27\lib\json\__init__.py", line 326, in loads
return _default_decoder.decode(s)
File "C:\Python27\lib\json\decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Python27\lib\json\decoder.py", line 382, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Invalid control character at: line 1 column 13 (char 13)
>>> j[13]
'\r'
"\r" is a perfectly legal character in a Python string.
How can I parse this JSON string, such that
>>> dct = somehow_parse_json(j)
>>> dct['data']
'foo \r\n bar'
I could easily just find and pop carriage return characters, but I would prefer if they can be saved.

您应该在 JSON 中转义斜杠：
如果您没有转义它们，则您的 JSON 无效（是有效的 Python 字符串）。
You should escape slashes in JSON:
If you are not escaping them, your JSON is invalid (being valid Python string).
从逻辑上讲，
python正在做应该做的事情！与旧的
CRLF相同（灵感来自打字机）CR = 回车
LF = 换行
'\r' 代表
CR但是 '\n' = CR + LF
所以，我的观点是，对于 json 来说，它绝对无效。
例如：
打印'\n 123456\rone'
# one3456
现在，如何使用
\r？只能用
\\r转义\rLogically
pythonis doing what should have been done !Its the same old
CRLF(inspired from typewriters)CR = Carraige Return
LF = Line Feed
'\r' stands for
CRBut '\n' = CR + LF
so, my point is that for
jsonits definitely not valid.For Eg:
print '\n 123456\rone'
# one3456
Now, how to use
\ranyway ?That should only escape
\rwith\\r
