我一直在尝试使用JSON来存储程序的设置。我似乎无法得到的Python 2.6的JSON解码器进行解码的多线串JSON ...Python阅读多行JSON
这里是例如输入:
.settings file:
"""
{\
'user':'username',\
'password':'passwd',\
}\
"""
我已经尝试了一些其他的语法此文件,我将在下面指出(它们引起的回溯)。读取文件中的
我的Python代码是
import json
settings_text = open(".settings", "r").read()
settings = json.loads(settings_text)
回溯这就是:
Traceback (most recent call last):
File "json_test.py", line 4, in <module>
print json.loads(text)
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/__init__.py", line 307, in loads
return _default_decoder.decode(s)
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/decoder.py", line 322, in decode
raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 1 column 2 - line 7 column 1 (char 2 - 41)
我承担“额外数据”三重引号。
下面是其他语法我都试过了.settings文件,用各自的回溯:
"{\
'user':'username',\
'pass':'passwd'\
}"
Traceback (most recent call last):
File "json_test.py", line 4, in <module>
print json.loads(text)
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/__init__.py", line 307, in loads
return _default_decoder.decode(s)
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/decoder.py", line 319, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/decoder.py", line 336, in raw_decode
obj, end = self._scanner.iterscan(s, **kw).next()
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/scanner.py", line 55, in iterscan
rval, next_pos = action(m, context)
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/decoder.py", line 155, in JSONString
return scanstring(match.string, match.end(), encoding, strict)
ValueError: Invalid \escape: line 1 column 2 (char 2)
'{\
"user":"username",\
"pass":"passwd",\
}'
Traceback (most recent call last):
File "json_test.py", line 4, in <module>
print json.loads(text)

raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded
如果我把所有的设置在同一行,其解码罚款。
这并不工作,当您创建的字符串解释器,但从文件读取时不起作用。 – 2010-05-26 14:01:50
@保罗:因为你的文件内容不正确! – SilentGhost 2010-05-26 14:07:15
