return nodejs script output to python

Question

I am trying to execute a nodejs script with python program and get the return output.

b.js

data : {
 "1":[],
 "2":[],
 "3":[],
 "4":[],
 "5":[],
 "6":[],
 "7":[],
 "8":[],
 "9":[],
 "10":[],
 "11":[{"id":"1","domain":"www.xxxxx.com","keywords":"白银交易平台","type":"Type1","time":["11","14","15","18"]}]
}


console.log(JSON.stringify(data))

a.py

if response.exitcode == 0:
  print(response.stdout)
else:
  sys.stderr.write(response.stderr)


b'{"1":[],"2":[],"3":[],"4":[],"5":[],"6":[],"7":[],"8":[],"9":[],"10":[],"11":[{"id":"1","domain":"www.xxxx.com","keywords":"\xe7\x99\xbd\xe9\x93\xb6\xe4\xba\xa4\xe6\x98\x93\xe5\xb9\xb3\xe5\x8f\xb0","type":"Type1","time":["11","14","15","18"]}]}\n'

From official docs of naked, response.stdout is returned NakedObject. How can I convert the returned NakedObject to python dictionary ?

If security is not a concern then have you tried eval? eval(response.stdout) — Paul Watson

Looks like you need to use json module.

Ex:

d = b'{"1":[],"2":[],"3":[],"4":[],"5":[],"6":[],"7":[],"8":[],"9":[],"10":[],"11":[{"id":"1","domain":"www.xxxx.com","keywords":"\xe7\x99\xbd\xe9\x93\xb6\xe4\xba\xa4\xe6\x98\x93\xe5\xb9\xb3\xe5\x8f\xb0","type":"Type1","time":["11","14","15","18"]}]}'
import json
print(json.loads(d))

Output:

{u'11': [{u'keywords': u'\u767d\u94f6\u4ea4\u6613\u5e73\u53f0', u'domain': u'www.xxxx.com', u'type': u'Type1', u'id': u'1', u'time': [u'11', u'14', u'15', u'18']}], u'10': [], u'1': [], u'3': [], u'2': [], u'5': [], u'4': [], u'7': [], u'6': [], u'9': [], u'8': []}

oh, sorry. I forgot there is line break at the end of the object b'{"1":[],"2":[],"3":[],"4":[],"5":[],"6":[],"7":[],"8":[],"9":[],"10":[],"11":[{"id":"1","domain":"www.xxxx.com","keywords":"\xe7\x99\xbd\xe9\x93\xb6\xe4\xba\xa4\xe6\x98\x93\xe5\xb9\xb3\xe5\x8f\xb0","type":"Type1","time":["11","14","15","18"]}]}\n' and then it gives me an error : json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

@Ekoar. That should not be a problem.
