How to use python api get request

I use the below function to get data from the web , but failed. I wonder whether urllib.quote use incorrect

i have used urllib.urlencode(xx) but it show not a valid non-string sequence or mapping object

and my request data is:

[{"Keys": "SV_cY1tKhYiocNluHb", "Details": [{"id2": "PK_2gl9xtYKX7TJi29"}], "language": "EN", "id": "535985"}]

Anyone can help. Thanks a lot !!!

###This Funcation call API Post Data
def CallApi(apilink, indata):
    token = gettoken()
    data = json.dumps(indata, ensure_ascii=False)
    print(data)
    headers = {'content-type': 'application/json', 'Accept': 'application/json', 'Authorization': 'Bearer %s' % (token)}
    proxy = urllib2.ProxyHandler({})
    opener = urllib2.build_opener(proxy)
    urllib2.install_opener(opener)
    DataForGet=urllib.quote(data)
    NewUrl= apilink + "?" + DataForGet
    request = urllib2.Request(NewUrl, headers=headers)
    response = urllib2.urlopen(request, timeout=300)
    message = response.read()
    print(message)

Error:

You could see the comment of urlencode

Encode a dict or sequence of two-element tuples into a URL query string

So you could choose removing the outer [] 

{"Keys": "SV_cY1tKhYiocNluHb", "Details": [{"id2": "PK_2gl9xtYKX7TJi29"}], "language": "EN", "id": "535985"}

Or use a two-element tuple

(('Keys', 'SV_cY1tKhYiocNluHb'), ('Details', [{...}]...)

Demo

>>> import urllib
>>> s = {"Keys": "SV_cY1tKhYiocNluHb", "Details": [{"id2": "PK_2gl9xtYKX7TJi29"}], "language": "EN", "id": "535985"}
>>> urllib.urlencode(s)
'Keys=SV_cY1tKhYiocNluHb&Details=%5B%7B%27id2%27%3A+%27PK_2gl9xtYKX7TJi29%27%7D%5D&language=EN&id=535985'
>>>
