使用python从命令行传递的json参数无法解码

Question

I am trying to pass a command line argument to a python file and load the json but I keep getting a valueerror: No Json object could be decoded.

json_test.py:

import json
import sys

json_dict = json.loads(sys.argv[1])

I then run this in the command line using:

python json_test.py '{"favorited": false, "contributors": null}'

And I get an error, even though I found this as an example of correct JSON on the web. Any ideas?

if you run print sys.argv[1] you probably get '{favorited: which the json module cannot decode into a json object.

try escaping your inner quotes so it is passed as 1 argument like so:

"{"\""favorited"\"": false, "\""contributors"\"": null}"
