PHP->Python JSON issue -

what doing wrong? python3:

>>> import json >>> s = "\"{'key': 'value'}\"" >>> obj = json.loads(s) >>> obj['key'] traceback (most recent call last):   file "<stdin>", line 1, in <module> typeerror: string indices must integers 

given json string produced json_encode() php

real string: {sessionid:5,file:\/home\/lol\/folder\/folder\/file.ttt}.

update: problem because transfer json string command line shell_exec in php, , read using sys.argv[1]... quotes removed shell.

php code (which runs python script shell_exec)

$arg = json_encode(['sessionid' => $session->getid(), 'file' => $filename]); shell_exec('python3 script.py ' . $arg); 

python code:

import json, sys s = json.loads(sys.argv[1]) #fails 

look @ json:

"\"{'key': 'value'}\"" 

you have string containing escaped quote, followed dictionary-like object, escaped quote. when try decode wind following:

"{'key': 'value'}" 

that's string, not dictionary.
