        return UserFavSerializer

=========================

//收藏
export const addFav = params => { return axios.post(`${local_host}/userfavs/`, params) }

//取消收藏
export const delFav = goodsId => { return axios.delete(`${local_host}/userfavs/`+goodsId+'/') }

export const getAllFavs = () => { return axios.get(`${local_host}/userfavs/`) }

//判断是否收藏
export const getFav = goodsId => { return axios.get(`${local_host}/userfavs/`+goodsId+'/') }

效果：

删除也能成功。
