python - Difficulty converting string to JSON object in order to urlencode it -


i'm having trouble converting string built on script json object (i'm trying build post data make post request api endpoint).

i'm getting following error:

bos-mpqpu:config_parse rabdelaz$ python3 lexparse.py {"__class__":"httptestclient","description":"cp codes","url":"://","serverip":"","method":"get","enabled":true,"headers":[],"tests":[],"purge":false,"procs":[]} traceback (most recent call last):   file "lexparse.py", line 448, in <module> print(ast.literal_eval(test_case_act_template.substitute({'protocol': "",'host': "", 'path' : "", 'query' : "", 'serverip' : "", 'tests' : ""})))   file "/library/frameworks/python.framework/versions/3.6/lib/python3.6/ast.py", line 85, in literal_eval return _convert(node_or_string)   file "/library/frameworks/python.framework/versions/3.6/lib/python3.6/ast.py", line 66, in _convert     in zip(node.keys, node.values))   file "/library/frameworks/python.framework/versions/3.6/lib/python3.6/ast.py", line 65, in <genexpr>     return dict((_convert(k), _convert(v)) k, v   file "/library/frameworks/python.framework/versions/3.6/lib/python3.6/ast.py", line 84, in _convert     raise valueerror('malformed node or string: ' + repr(node)) valueerror: malformed node or string: <_ast.name object @ 0x103c50c18>

here code generates above:

test_case_act_template = template('{"__class__":"httptestclient","description":"cp codes","url":"$protocol://$host$path$query","serverip":"$serverip","method":"get","enabled":true,"headers":[],"tests":[$tests],"purge":false,"procs":[]}')   print(test_case_act_template.substitute({'protocol': "",'host': "", 'path' : "", 'query' : "", 'serverip' : "", 'tests' : ""}))  print(ast.literal_eval(test_case_act_template.substitute({'protocol': "",'host': "", 'path' : "", 'query' : "", 'serverip' : "", 'tests' : ""})))

notice first print statement results in output line starts {"__class__"

my overall objective urlencode json string searching on lead me believe should first ast.literal_eval before urlencoding it.

the end goal looks this:

form_data = {'name' : 'cp code demo', 'configfilename' : '1-dr4e2_kona-ion.aws-eu-ssl.template_pm-2', 'type' : 'json', 'script' : urlencode(json.load(post_data))}

where post_data series of template substitutions.

the original error lead me start looking ast.literal_eval follows:

   traceback (most recent call last):    file "lexparse.py", line 521, in <module> form_data = {'name' : 'cp code demo', 'configfilename' : '1-dr4e2_kona-ion.aws-eu-ssl.template_pm-2', 'type' : 'json', 'script' : urlencode(post_data)}    file "/library/frameworks/python.framework/versions/3.6/lib/python3.6/urllib/parse.py", line 862, in urlencode "or mapping object").with_traceback(tb)     file "/library/frameworks/python.framework/versions/3.6/lib/python3.6/urllib/parse.py", line 854, in urlencode   raise typeerror typeerror: not valid non-string sequence or mapping object

just in line question, template seemingly produces valid json parse python dict , give urllib.parse.urlencode() turn valid url params, like:

import json urllib.parse import urlencode string import template  your_template = template('{"__class__":"httptestclient","description":"cp codes",'                          '"url":"$protocol://$host$path$query","serverip":"$serverip",'                          '"method":"get","enabled":true,"headers":[],"tests":[$tests],'                          '"purge":false,"procs":[]}')  post_data = your_template.substitute({'protocol': "",                                       'host': "",                                       'path': "",                                       'query': "",                                       'serverip': "",                                       'tests': ""})  form_data = {'name': 'cp code demo',              'configfilename': '1-dr4e2_kona-ion.aws-eu-ssl.template_pm-2',              'type': 'json',              'script': urlencode(json.loads(post_data))}  print(form_data)

then can feed whatever want. i'd still advise on solving problem have certificates offsetting curl - issues might experience when trying pass large amount of data via cli can overcome issues you've been experiencing certificates.
