Record a possible problem that the browser could not carry cookies.
I received the demand and was preparing to develop as before, but I failed to log in. After logging in, I jumped back to the login page. At that time, my first reaction was that the cookie did not take effect or was wrong. The final discovery is browsing the problem, through the Internet to find the answer;
Enter Chrome ://flags/ in Google Chrome
Search for SameSite in the page search box that appears
Set it to disable and restart the browser. If it still doesn’t clear the previous cookie, try again
