DRF不会将原始JSON字符串发送到浏览器。它返回一个JSON字符串,希望绕过调用json.load文件

database_json = '{"from": ["the", "database"]}'
raw_json = '{"json": {"example": %s}}' % database_json
return HTTPResponse(raw_json, content_type='application/json')

如果您需要对json的“json”和“example”部分进行一些验证/灵活性,那么这就有点困难了,您必须制作一个自定义编码器并对字符串进行monkey-patch转义(因为它将转义双引号):

from contextlib import contextmanager
import json

class RawJSON(str):
  def __init__(self, raw_json):
    return super(RawJSON, self).__init__(raw_json)


class JSONEncoderWithRawSupport(json.JSONEncoder):
  @contextmanager
  def patched_encoder(self):
    default_encoder = json.encoder.encode_basestring_ascii

    def _encode(o):
        if isinstance(o, RawJSON):
            return o
        return default_encoder(o)
    json.encoder.encode_basestring_ascii = _encode
    yield
    json.encoder.encode_basestring_ascii = default_encoder

  def iterencode(self, *args, **kwargs):
    with self.patched_encoder():
        return super(JSONEncoderWithRawSupport, self).iterencode(*args, **kwargs)     


database_json = RawJSON('{"from": ["the", "database"]}')
my_dict = {"json": {"example": database_json}}
my_json = json.dumps(my_dict, cls=JSONEncoderWithRawSupport)
return HTTPResponse(my_json, content_type='application/json')

JSONField DRF序列化程序

#serializer.py
from rest_framework import serializers


class Myserializer(serializers.Serializer):
    myjson = serializers.JSONField()


#views.py
class MyView(....):
    .....
    myjson = {"myjson":{some requeried json}}
    serializer = Myserializer(myjson)
    serializer.is_valid(True)
    return Response(data=serializer.data)
