Konvertieren einer Zeichenfolge zu JSON

Question

Ich möchte diese Zeichenfolge in eine JSON dict konvertieren:

{u'Processes': [[u'root', u'3606', u'0.0', u'0.2', u'76768', u'16664', u'?', u'Ss', u'20:40', u'0:01', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4088', u'0.0', u'0.2', u'88544', u'20156', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4090', u'0.0', u'0.2', u'88552', u'20140', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4097', u'0.0', u'0.2', u'88552', u'20112', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4110', u'0.0', u'0.2', u'88548', u'20160', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0']], u'Titles': [u'USER', u'PID', u'%CPU', u'%MEM', u'VSZ', u'RSS', u'TTY', u'STAT', u'START', u'TIME', u'COMMAND']} 

So habe ich json.dumps und json.loads aber der Ausgang war kein gültiger JSON. Ich verstehe, dass JSON doppelte Anführungszeichen anstelle von einfachen Anführungszeichen benötigt, aber ich denke nicht, dass die Lösung zum Suchen und Ersetzen der beste Weg ist, dieses Problem zu lösen. Gibt es einen geeigneteren Weg, es zu tun?

import json 
data = {u'Processes': [[u'root', u'3606', u'0.0', u'0.2', u'76768', u'16664', u'?', u'Ss', u'20:40', u'0:01', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4088', u'0.0', u'0.2', u'88544', u'20156', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4090', u'0.0', u'0.2', u'88552', u'20140', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4097', u'0.0', u'0.2', u'88552', u'20112', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4110', u'0.0', u'0.2', u'88548', u'20160', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0']], u'Titles': [u'USER', u'PID', u'%CPU', u'%MEM', u'VSZ', u'RSS', u'TTY', u'STAT', u'START', u'TIME', u'COMMAND']} 
data = json.dumps(data) # dict to string 
data = json.loads(data) # string to json 
print data['Processes']

Verwenden Sie ast.literal_eval, um die Zeichenfolge in ein gültiges Python-Objekt zu konvertieren.

Bewerten Sie einen Ausdrucksknoten oder eine Zeichenfolge, die eine Python Literal- oder Containeranzeige enthält, sicher. Die angegebene Zeichenfolge oder der angegebene Knoten darf nur aus den folgenden Python-Literalstrukturen bestehen: Strings, Bytes, Zahlen, Tupel, Listen, Dicts, Mengen, Boolesche Werte und None.

s = "{u'Processes': [[u'root', u'3606', u'0.0', u'0.2', u'76768', u'16664', u'?', u'Ss', u'20:40', u'0:01', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4088', u'0.0', u'0.2', u'88544', u'20156', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4090', u'0.0', u'0.2', u'88552', u'20140', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4097', u'0.0', u'0.2', u'88552', u'20112', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0'], [u'root', u'4110', u'0.0', u'0.2', u'88548', u'20160', u'?', u'S', u'20:40', u'0:00', u'/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0']], u'Titles': [u'USER', u'PID', u'%CPU', u'%MEM', u'VSZ', u'RSS', u'TTY', u'STAT', u'START', u'TIME', u'COMMAND']}" 
o = ast.literal_eval(s) 
assert 'Processes' in o 

Verwenden json.dumps es zu JSON-String auszugeben.

import json 
json.dumps(o) 
# '{"Titles": ["USER", "PID", "%CPU", "%MEM", "VSZ", "RSS", "TTY", "STAT", "START", "TIME", "COMMAND"], "Processes": [["root", "3606", "0.0", "0.2", "76768", "16664", "?", "Ss", "20:40", "0:01", "/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0"], ["root", "4088", "0.0", "0.2", "88544", "20156", "?", "S", "20:40", "0:00", "/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0"], ["root", "4090", "0.0", "0.2", "88552", "20140", "?", "S", "20:40", "0:00", "/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0"], ["root", "4097", "0.0", "0.2", "88552", "20112", "?", "S", "20:40", "0:00", "/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0"], ["root", "4110", "0.0", "0.2", "88548", "20160", "?", "S", "20:40", "0:00", "/usr/local/bin/python2 /usr/local/bin/gunicorn app:app -b 0.0.0.0:80 --log-file - --access-logfile - --workers 4 --keep-alive 0"]]}' 

Oder verwenden json.dump es Dump-Objekt-Datei, wenn es das ist, was Sie wollen.
