python json.dumps()的数据包含\，如何清理它

Question

def getJson(filmList):
film_json = FilmJson()
for video in filmList:
    videoName = video.videoName
    videoUrl = video.videoUrl
    videoTime = video.videoTime
    dic = {}
    if videoName is None:
        break

    if videoUrl is None:
        dic['videourl'] = ""
    else:
        dic['videourl'] = videoUrl


    if videoTime is None:
        dic['videotime'] = ""
    else:
        dic['videotime'] = videoTime
    dic['videoname'] = videoName


    film_json.videolist.append(dic)

dict__ = film_json.__dict__
print(dict__)

return dict__

浏览器发送get请求

后台打印

{'filmid': '', 'videolist': [{'videourl': '', 'videotime': '', 'videoname': 'Lifeline'}, {'videourl': '', 'videotime': '', 'videoname': 'Ex Static'}, {'videourl': '', 'videotime': '', 'videoname': 'test'}]}

.

@api_view(http_method_names=['GET'])
@permission_classes((permissions.AllowAny,))
def sendFilm(request):
   ....
    myjson = jsonbean.getJson(filmList)



    return Response(json.dumps(myjson,ensure_ascii=False))

postman 测试得到结果

"{\"filmid\": \"\", \"videolist\": [{\"videourl\": \"\", \"videotime\": \"\", \"videoname\": \"Lifeline\"}, {\"videourl\": \"\", \"videotime\": \"\", \"videoname\": \"Ex Static\"}, {\"videourl\": \"\", \"videotime\": \"\", \"videoname\": \"test\"}]}"

如何解决问题

Answer 1

你被双重甩了。

你只需要 json.dumps() 一次。发生此错误是因为您对已经是 JSON 的对象使用了 json.dumps()。

return Response( myjson ) 应返回一个不带 \" 的常规对象。

因为 myjson 已经是一个 JSON 字符串而不是字典对象。
