通过生成随机数令牌来防止 CSRF？
I was reading This article about preventing CSRF by creating a nonce token which going to be sent as variable in ajax function along with a session hold the same value as in the token. Is this a good idea because I realy don't like the useing of sessions specially with big website which has many active users all the time , which going to affect the general performance ?

不，只要您为每个用户提供独特的、不可猜测的价值，就不需要随机数。例如，它可以是
SHA1（user_id +“无人知道的秘密字符串”）。我在另一个问题中回答了随机数和CSRF之间的区别：

No, nonce is not necessary as long as you'll have unique, unguessable value for each user. It could be for example
SHA1( user_id + "secret string nobody knows").I've replied about difference between nonces and CSRF in another question:
