On some websites, when you want to login, you need to enter a captcha as well. If I want to provide support for an user to enter a captcha into my application ( which will then log into the website ), how would I do this?
My problem is that the link to the captcha image is like this: example.com/captcha
, and it serves a different image each time it's accesed.
My approach is like this:
- request page
- download image
- show image to user
- user inputs login information
- application logs in
The thing is, if you download the image in order to show it to the user, you're actually receiving a different image than the one generated when the page was loaded, right? How can I get to the image that was generated when the page was loaded, so that when I show it to the user, it's the correct one?
The question is language agnostic.
