Because http requests are not secured requests,they may be hijacked. And files downloaded from http may be replaced with malware, threatening the security and privacy of users. The chrome browser will gradually restrict the download of http from HTTPS pages starting from version 83.
In order to ensure the user security of Baidu APP, Baidu APP will restrict the automatic download of HTTPS pages (downloads without user interaction) from version 11.26. Please adjust the download link in time to avoid affecting your page.
