Get Cookies By login qqmail.Login method is username and password.not qrcode

I am looking for a Freelancer to develop a system that will allow me to log in to qqmail with username and password and get its cookies. I have a qqmail account, and am looking for a Freelancer who is experienced developing with C++. The overall goal is to log into the account and capture the corresponding cookies, which will be used for further purposes. This project requires a reliable and safe system and I am open to any suggestions or solutions a Freelancer may have.
