Python json，不必要的斜杠

我正在创建一个简单的服务器端应用程序，我使用内置模块“json”创建对客户端的应答

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

我的班级在哪

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)

它可以工作，但作为回应，我有一个不必要的斜杠：

为什么它们出现在我的答案中？

您的

to_json（）

方法返回一个包含json的字符串

json.dumps（）

然后转义引号，这是json中的一个特殊字符

您的

to_json（）

应该返回一个

dict

，然后可以通过

json.dumps（）对其进行编码

更好但更复杂的方法可能是编写自定义子类。
最简单的方法是：

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

jsonString = json.dumps(list)

jsonlist = json.loads(jsonString)

这对我来说很有用。
提示：
.to_json（）
和
json.dumps（）
都有什么作用？只是标准库惩罚你写“responce”。这些都不是多余的。它们在字符串中转义引号。谢谢。这是我正在寻找的。这是不必要的昂贵。
//convert list to string and then load it as json

jsonString = json.dumps(list)

jsonlist = json.loads(jsonString)
