Python实现JD口罩预约+抢购
疫情期间，口罩成了市面上的硬通货，简直就是“一罩难求”，不过在某些电商平台上有预约抢购的医用外科口罩，抢得到抢不到就要看个人运气了，但是我坚信科技改变生活，就用Python写了个抢购的脚本，可以自动预约，到点自动抢购JD。
ps:仅供技术交流
思路：
- 模拟登陆（参考github上已有大神写好的登陆模块）
- 输入需要抢购的物品，获取商品信息
- 到点自动抢购，提交订单
实现步骤：
4. 发现jd的抢购规则
找一个也需要预约抢购的商品，通过Fiddler抓包，找出目标接口
这里推荐去抓包一下N95的抢购，因为价格稍微有点高，所以一般都可以手动抢，这样就可以抓包分析出接口地址了。
5. 编码
根据找到的接口地址的规律，开始写代码
代码实现：
假设我们现在要抢购这一个
商品信息url：https://item.jd.com/100011412340.html
访问并抓包，分析数据包：
- url:https://item.jd.com/100011412340.html
进入商品主页
2.url：https://yushou.jd.com/youshouinfo.action?callback=fetchJSON&sku=100011412340&_=1584107644620
如图，这个接口返回了商品的信息，包含抢购预约时间等等，sku是商品id，_是时间戳
3.点击立即抢购
进入提交页面 ，提交订单：
提交订单url：https://marathon.jd.com/seckillnew/orderService/pc/submitOrder.action?skuId=100011412340，post参数过去
参数包含有收货地址等，这些参数可以在https://marathon.jd.com/seckillnew/orderService/pc/init.action这个接口中获得，post
data = {
“sku”:goodsno,
“num”:1,
“isModifyAddress”:False
}
就可以获得所有的参数了。
具体实现看代码吧。
祝大家都能抢到口罩。
