使用代理在Nginx HTTP中重定向到HTTPS不起作用

Question

我想使用代理到我的Angular应用将HTTP重定向到HTTPS。 HTTP> HTTPS重定向有效，但是稍后，ssl代理无法到达localhost：4200上的Angular应用。

当我仅将端口设置为80时。

我还尝试将两个服务器使用相同的服务器名称，两个服务器中的代理服务器，等等...

server {
listen 80;
return 301 https://$host$request_uri;
}

server {

listen 443;
server_name example.com;

ssl_certificate           /etc/nginx/ssl/example.com.crt;
ssl_certificate_key       /etc/nginx/ssl/example.com.key;

ssl on;
ssl_session_cache  builtin:1000  shared:SSL:10m;
ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
ssl_prefer_server_ciphers on;

access_log            /var/log/nginx/site.access.log;

location / {

proxy_set_header        Host $host;
proxy_set_header        X-Real-IP $remote_addr;
proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header        X-Forwarded-Proto $scheme;

# Fix the “It appears that your reverse proxy set up is broken" error.
proxy_pass          http://localhost:4200;
proxy_read_timeout  90;
proxy_redirect      http://localhost:4200 https://example.com;
}
}
