파이썬 json, 불필요한 슬래시

Question

나는 간단한 서버 측 애플 리케이션을 만들고 있는데, 나는 클라이언트에 대한 대답을 만들기 위해 "json"모듈을 내장하고있다.

if isinstance(obj, (list, tuple)): 
    return json.dumps({key: [o.to_json() for o in obj if 
          isinstance(o, JsonAble)]}, ensure_ascii=False) 

경우 목록

class ArtistSearchResult(JsonAble): 

    def to_json(self): 
     return json.dumps({'name': self.name, 'descr': self.descr, 
          "url": self.url, 'genres': self.genres}, 
          allow_nan=False, ensure_ascii=False) 

에서 그것은 내가 불필요한 슬래시가 응답 작동하지만, 내 수업 :

이 왜 내 대답에 등장을?

Answer 1

to_json() 메서드는 JSON이 포함 된 문자열을 반환합니다. json.dumps() 그러면 JSON의 특수 문자 인 따옴표를 이스케이프 처리합니다.

귀하의 to_json()json.dumps()

class ArtistSearchResult(JsonAble): 

    def to_json_dict(self): 
     return {'name': self.name, 'descr': self.descr, 
       'url': self.url, 'genres': self.genres} 

에 의해 다음 인코딩 할 수있는 dict를 반환해야 더 좋은,하지만 더 복잡한 방법은 아마 사용자에게 JSONEncoder 서브 클래스를 작성하는 것입니다. 나를 위해

//convert list to string and then load it as json 

jsonString = json.dumps(list) 

jsonlist = json.loads(jsonString)
