proxy_pass - client-side http protocol accesses nginx, why can't reverse proxy nginx for https?

Question

I configured the following virtual host in nginx.
When I visit http://127.0.0.1:8112/, it should be possible to reverse proxy to https//www.baidu.com, because the verification of the server certificate should be performed during proxy_pass.

I went to test again. I personally tested that I can connect to nginx via http and get out of nginx via https. The following is my test configuration, which allows me to access the Baidu homepage.

server {
    listen 8113;
    server_name saas-portal.test.cn;
    location / {
            proxy_set_header Host "www.baidu.com";
            proxy_pass https://test8113;
    }
}
upstream test8113 {
    server 115.239.211.112:443;#此ip为百度ip
}
