Python3 simplejson转储将Django查询dict键转换为小写

Question

python 3.7 我有一个POST请求，它在django中返回一个查询dict，如下所示

<QueryDict: {'tbl': ['[{"Unnamed: 0":"0","RecordID":"0","ID":"1","Site Ser
ved":"51st Street Academy","Program":"Outreach","Boro":"Queens","Manager":"Steve
 Waters","Event Date":"2019-11-19","Address":"7605 51st Street ","Zip":"11373","
Activity":"Word on the Street\\n","Grc":"42","ErrorMsg":"ADDRESS NUMBER OUT OF R
ANGE","Version":"18D","Suggested Corrected Address":"76-05 51st Ave, Elmhurst, N
Y 11373"},{"Unnamed: 0":"1","RecordID":"2","ID":"3","Site Served":"Cardinal Spel
lman High School","Program":"Outreach","Boro":"Brooklyn","Manager":"Lee Eastmond
","Event Date":"2019-11-04","Address":"1 Cardinal Spellman Place","Zip":"10466",
"Activity":"Alive at 25","Grc":"EE","ErrorMsg":"1 CARDINAL SPELLMAN PLACE NOT RE
COGNIZED. THERE ARE 009 SIMILAR NAMES.","Version":"18D","Suggested Corrected Add
ress":"1 Cardinal Spellman Pl, The Bronx, NY 10466"},{"Unnamed: 0":"2","RecordID
":"37","ID":"38","Site Served":"St. Marks Day  School","Program":"Outreach","Bor
o":"Brooklyn","Manager":"Steve Waters","Event Date":"2019-11-06","Address":"1346
 Presidnt Street","Zip":"11213","Activity":"My Safety Toolbox\\nSafety Smarts","
Grc":"11","ErrorMsg":"1346 PRESIDNT STREET NOT RECOGNIZED. THERE ARE NO SIMILAR
NAMES","Version":"18D","Suggested Corrected Address":"1346 President St, Brookly
n, NY 11213"}]']}>

然后我就跑

simplejson.dumps(variable_holding_query_dict)

出于某种原因，它将键小写

如何不让它返回小写键

我需要POST请求返回的原始案例，因此我无法使用任何我想要的案例创建新的dict

Answer 1

怎么样

import json

json.dumps(variable_holding_query_dict.dict())

例如：

from django.http import QueryDict
import json


qd = QueryDict('', mutable=True) # just a dummy QD example
qd.update({'example': 'UPPERCASE', 'example2': 'any value'})
json.dumps(qd.dict())

JSON转储结果：

'{"example": "UPPERCASE", "example2": "any value"}'
