关于验证码部分,在我这篇文章里说的挺详细的了:Python高级应用(3)—— 为你的项目添加验证码
这里还是再给一个前后端分离的实例,因为极验官网给的是用session作为验证的,而我们做前后端分离的用的是token,而不是session,所以对于目前来说就不适用了,所以需要根据具体业务逻辑来改动。当然,大佬可以直接忽略
好的,直接上例子:
还是用的 Python高级应用(3)—— 为你的项目添加验证码 这文章最后的LoginAuth例子,这里改成使用djagnorestframwork的项目:
url没变:
view也只是做了稍微的小改动,改动部分就是我标记出来的部分,因为不能用session,所以这里采用redis存储数据并获取数据,有关redis配置请移步:数据库之redis篇(3)—— Python操作redis
html,只改了两处的请求地址,写成了绝对地址
在启动项目之前,需要设置一个中间件,不然会有跨域请求问题,有跨域请求解决问题,请移步:前后端分离djangorestframework——解决跨域请求 这里就不多介绍了
在utils目录下创建一个中间就爱你,定义类名Mycors
配置文件里导入:
注意,由于已经设置了中间件添加允许请求头,那个csrf的中间件就可以不用管,当然你注释掉也没有问题
启动项目:
然后再pycharm下,单独对html文件启动,作为一个客户端来访问:
点击验证码:
没有问题

好的,这样的感觉还是在搬砖,用的别人的代码,再来一个使用vue作为前端主要代码,对html文件做大的改写
这次是用的是极验给第一个案例,弹出式的:
同样的,除了html文件,其他没做多大改动:
url:
view,redis自己记着配置就行,还要注意的是这次这里用的request.data,不是request.POST了,我在这里耗了好久
html:
启动项目,解释一下,不知道是不是我的浏览器显示比例的问题,我只要用自己的id和key,它这个验证码按钮就会跑到左边去,我试了用官方给的示例id和key就正常,如果你们也遇到就自己去调试css了,这里暂且这样了

(其他没做任何改动,同上)
好的,完事儿了。感兴趣的可以把极验给的三个验证码都由之前的jquery改成vue试试,哈哈
总结:
说白了还是那一套官方给你的案例,根据自己实际情况改来改去就行了,不过得看得懂极验给的demo才可以随意改动
