Request interface 403, so that the Referer in the request header is not of the current domain name?

Apr.09,2021

it's normal
referer just indicates to the server which page it jumped from.

if there is iframe, the referer after multiple jumps in iframe is calculated separately by chrome
if the current page is loaded for the first time, it may also come from the previous website or script

according to the supplement of the question, I opened this page and took a look at

there is indeed an iframe, here, and the request is made by a web page in iframe, so referer is naturally the address of this iframe
