What should I do if curl simulates logon to the educational administration system into a redirection loop?

However, the target URL of the redirection is still the current page. After analysis, we found that a redirection cycle occurs. PS: After logging on to the educational administration system locally, you can enter the target website in the IE browser directly, but if you use Firefox or Chrome, the redirection loop will show: Objectmovedto... however, the target URL of the redirection is still the current page. Later I analyzed it and found that there was a redirection loop.

Install wireshark, intercept all request data of IE, and use curl for complete simulation

Add curl to the url specified in Location in the http header recursivelySetopt ($ ch, CURLOPTFOLLOWLOCATION, 1); try
