Java简单实现短信验证登录(Session、Redis)

当注册完成后,用户去登录会去校验用户提交的手机号和验证码,是否一致,如果一致,则根据手机号查询用户信息,不存在则新建,最后将用户数据保存到redis,并且生成token作为redis的key,当我们校验用户是否登录时,会去携带着token进行访问,从redis中取出token对应的value,判断是否存在这个数据,如果没有则拦截,如果存在则将其保存到threadLocal中,并且放行。如果手机号合法,后台此时生成对应的验证码,同时将验证码进行保存,然后再通过短信的方式将验证码发送给用户。

【crawler笔记】R语言简单动态网页爬虫(rvest包)示例

1、爬虫目标 大家普遍认为Python的爬虫功能强大,但在解决动态加载或者登陆网站时,Python存在一定困难的,相对于一些普通爬虫,使用R语言会更方便。 以https://www.thepaper.cn/为例,爬取首页的新闻(标题、内容、时间),主要采用的是动态网页中常用的httr包。 初始学习时,参考了B站《20分钟入门基于R语言的网络爬虫_哔哩哔哩 (゜-゜)つロ 干杯~-bilibili》的视频,但代码运行出现了报错,所以在原代码上做了修改。 2、代码分析及报错修改 library(rv

第一种方式(不推荐,因为结果可能会出现错误): String code = String.valueOf(new Random().nextInt(1000000)); 这种方式有问题,问题在于:在连续生成多次的情况下,可能会生成小于6位的验证码 测试: for (int i=0;i<100;i++) { // 生成6位验证码,这种方式有问题,问题在于:在连续生成多次的情况下,可能会生成小于6位的验证码 // 这种方式不可取,因为会出错错误(
