How to convert the following odd string into json in python?

Question

How to convert this string into json in python?

>>> data = '[for: css=a[title="See LLCAutoSept files"]]'
>>> json.dumps(data)
'"[for: css=a[title=\\"See LLCAutoSept files\\"]]"'

I've tried using json.dumps(), however the output json is could not be validated on jsonlint.com

Answer 1

You are looking at the Python string representation. It's valid Python code, containing valid JSON.

Print the value:

>>> imp
>>> data = '[for: css=a[title="See LLCAutoSept files"]]'
>>> print json.dumps(data)
"[for: css=a[title=\"See LLCAutoSept files\"]]"

JSONlint is using the older , stricter RFC 4627 that requires the top level to be an array or object, so it won't validate a JSON string.

However, Python's json.dumps() produces valid RFC 7159 output.

If your application requires JSONlint compliance, then by all means add a list or dictionary:

>>> print json.dumps([data])
["[for: css=a[title=\"See LLCAutoSept files\"]]"]
>>> print json.dumps({'data': data})
{"data": "[for: css=a[title=\"See LLCAutoSept files\"]]"}

JSONlint.com validates either of these as valid.

There was, for a time, quite some confusion over this, with RFC 4627, ECMA-262 and ECMA-404 and actual implementations disagreeing over what was allowed; at least RFC 7159 agrees with ECMA-404 now on this. Also see What is the minimum valid JSON?

Answer 2

这是无效的json，因为它没有数组的键，也没有用于打开和关闭大括号或方括号的键，因此您无法在jsonlint.com上对其进行验证

Answer 3

This works for me

data = {'string':'[for: css=a[title="See LLCAutoSept files"]]'}
print(json.dumps(data))
