修改了prompt的选择方式,采用noneprompt库,效果如图所示

详见github

前言

经常在魔力赏市集捡漏的我发现有人在闲鱼卖魔力赏脚本,b站魔力赏市集自身没有搜索功能,且自带的筛选不是很好用。这样一想,为何我不自己做一个简单的搜索脚本方便我自己后续捡漏。

分析

先打开魔力赏市集的网页版本,也可以直接分析手机端的,但是我觉得网页端的更方便一些。打开控制台看,然后选择fetch/xhr。可以看到请求list接口的返回即我们需要的。

请求链接为https://mall.bilibili.com/mall-magic-c/internet/c2c/v2/list,请求为

1
{"categoryFilter":"","sortType":"PRICE_ASC","priceFilters":["2000-3000"],"discountFilters":["70-100"],"nextId":null}

其中categoryFilter为分类,nextId为下一页的id,sortType为排序方式,priceFilters为价格区间,discountFilters为折扣区间。我们可以通过修改这些参数来获取不同的数据。

请求参数

其中categoryFilter的值为

我们需要的值就在data中,且我们的data中含有nextIddata两个key,其中nextId来获取下一页的数据,data就是我们需要的手办数据。

细节key

  • c2cItemsId 市集商品id,可跳转到详细页 https://mall.bilibili.com/neul-next/index.html?page=magic-market_detail&noTitleBar=1&itemsId={c2citemsId}&from=market_index
  • type 类型(什么类型暂且不明)
  • c2cItemsName 市集展示商品名
  • detailDtoList 商品细节,因为可能是多个商品捆绑,所以是list
    • blindBoxId 应该是盲盒id
    • itemsId 猜测是会员购的id
    • skuId 未知
    • name 商品名
    • img 商品图
    • marketPrice 原价,单位分
    • type 类型(什么类型暂且不明)
    • isHidden 是否隐藏,猜测和福袋相关
  • totalItemsCount 总共商品数
  • price 市集价格,单位分
  • showPrice 展示价格,字符串,单位元
  • showMarketPrice 展示原价,字符串,单位元
  • uid 卖方uid
  • paymentTime 未知
  • isMyPublish 是否为本人发布
  • uname 用户名
  • uspaceJumpUrl 用户空间url
  • uface 用户头像

事实上,请求的时候还需要带上我们的cookie,这样才能获取到我们的数据。否则会返回未登录

风控

在请求的时候需要注意b站的风控,不要频繁的请求。否则太快会直接返回412
