python - 如何防止狂点提交表单按钮导致的数据重复？

Answer 1

Add this line to the form

<input type="hidden" name="token" value="随机字符串">

Then the server will make a judgment and just ignore the duplicate value.
Very original method

Answer 2

Thank you for the invitation. There are roughly two ways to prevent submissions

1. 服务端生成一个token放在页面中，提交当前页面时验证这个token，这也是防csrf的一个方法哦
2.正如前面各位同学说的在前端做处理，加一个类似disable就是禁止的那一堆玩意儿，ajax的话可以写在beforsend这里
