json loggin 的使用,小案例

        with open("longmaotian_dict_josn.txt",'w',encoding='utf-8') as f:
            json.dump(dic,f)
            f.close()

    else:
        with open("longmaotian_dict_josn.txt",'r',encoding="utf-8") as f1:
            dic = json.load(f1)
            username = dic.get("username")
            f1.close()
            return  username
