将一组字符串转换为python中的json

Question

I am currently working on setting up a flask server for my front end. The request I get is in the form the following JSON object:

InputJson = {"text":"Field1:A|Field2:B|Field3:C","format":"Reader"}

I would like to convert the text field to a proper JSON:

OutputJson = {"Field1":"A","Field2":"B","Field3":"C"}

What I did so far:
I first replaced the pipes using string.replace in python. However, I end up with a plain string which I am not able to convert to json.

I have tried using json.loads on the cleaned string (I replaced the | with , .

Any help here would be great.

Answer 1

You can split your string on "|", then split each part on ":", feeding the pairs into a dict:

output = dict( keyvalue.split(':') for keyvalue in orig_value.split('|') )

You don't need to use any json-parsing tools for that, because the format of the string you're parsing has nothing to do with json formatting.
