这个是不是在 https://github.com/hhyo/Archery/blob/master/common/utils/extend_json_encoder.py 这里注册一个新的类型就行了？

你的意思是加
@convert.register(dict)
def _(o):
return json.dumps(o)

@convert.register(list)
def _(o):
return json.dumps(o)

然后靠这里的地方能统一解决？ 我试了，不好像。
cls 只能处理 他处理不了未知的类型？

return HttpResponse(
json.dumps(
result,
use_decimal=False,
cls=ExtendJSONEncoderFTime,
bigint_as_string=True,
),
content_type="application/json",
)
