Ajax request speed issue
I want to prevent from user sending requests from ajax too fast. I wrote a validation in controller as bellow.
def before_action
if session[:expires_at].nil?
logger.info "Operation is legal"
session[:expires_at] = Time.current + 3.seconds
elsif Time.current > session[:expires_at].to_time
logger.info "Operation is legal"
session[:expires_at] = Time.current + 3.seconds
else
logger.info "Error: Operation too fast"
render json: { msg: "Operation too fast",res: "Err"}
return
end
sleep 2 <-- The issue happends here
end
The sleep 2 seconds means my program excution time. If I remove sleep 2 seconds, everything works fine.The result would like below when I send the requests really fast.
-----------Logs-------------
Operation is legal
Error: Operation too fast
Error: Operation too fast
Error: Operation too fast
Error: Operation too fast
Error: Operation too fast
Operation is legal
Error: Operation too fast
Error: Operation too fast
Error: Operation too fast
----------------------------
But, if the second or more resquests been sended before the first one excutes finished. The result would be unexpected. If I add sleep 2 in the validation code.
-----------Logs-------------
Operation is legal
Operation is legal
Operation is legal
Error: Operation too fast
Error: Operation too fast
Error: Operation too fast
Error: Operation too fast
Operation is legal
Operation is legal
Error: Operation too fast
Error: Operation too fast
----------------------------
I am totally confused for this situation. Would the session value not being saved before the request finished? How should I fix this issue?

It's not working for me. The results are always "Operation is legal" after added request.session_options[:skip] = true.

Yes, I added at the first line of the function. Nvm I've solved it by using two steps validation. A validating request will be sent before user's request.

it looks like the session variables will be stored later in processing a controller lifecycle? a workaround could be to use redis for this case?
you should find a way to be sure a variable you are using is persistent over more requests in parallel.

I guest I have to send a validating request first everytime before doing real request to see if the opreation is valid.
