如何将Shiny App的http地址替换为https

Question

我有一个Shiny应用程序托管在Digitalocean中 ，网络服务器为Nginx 。 网址看起来像

http://www.exacmple.com/ShinyApp

但是，我希望是否可以将http更改为https。 即对此应用程序的所有请求将被路由到https： ///www.exacmple.com/ShinyApp

我已经从letsencrypt安装了SSL证书，并且证书文件位于以下地址：

/etc/letsencrypt/live/example.com/fullchain.pem;
/etc/letsencrypt/live/example.com/privkey.pem;

目前，我的Nginx代理文件设置如下：

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
##

# Default server configuration
#
  map $http_upgrade $connection_upgrade {
      default upgrade;
      ''      close;
    }



server {
    listen 80 default_server;
    listen [::]:80 default_server;
        server_name example.com www.example.com;
    if ($http_host = example.com) {
            rewrite  (.*)  https://www.example.com$1;
          }



    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }

location /ShinyApp/ {
      rewrite ^/ShinyApp/(.*)$ /$1 break;
      proxy_pass http://localhost:4242;    
      proxy_redirect http://localhost:4242/ $scheme://$host/ShinyApp/;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;
      proxy_read_timeout 20d;
      proxy_buffering off;
    }
}

为了实现https ，我将这个文件添加如下（ 位置部分 ）

location /ShinyApp/ {
      rewrite ^/ShinyApp/(.*)$ /$1 break;
      SSLEngine on
      ssl_certificate           /etc/letsencrypt/live/example.com/fullchain.pem;
       ssl_certificate_key       /etc/letsencrypt/live/example.com/privkey.pem;

      ProxyPreserveHost On
      proxy_pass http://localhost:4242;
      roxyPassReverse http://localhost:4242;
      proxy_redirect http://localhost:4242/ $scheme://$host/ShinyApp/;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;
      proxy_read_timeout 20d;
      proxy_buffering off;
    }

但是上述更改无法实现https请求。

我已经浏览了Web上的各种建议（例如， 适用于Shiny应用程序的HTTPS？ ），但是找不到任何可行的解决方案。

任何指向正确方向的指针都将非常有帮助。

谢谢，

常见的做法是使用两个服务器块：

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name example.com www.example.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;
    server_name example.com www.example.com;
    ssl_certificate     /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    ... # root, index and other top-level directives here
    location /ShinyApp/ {
        # your backend configuration here
    }
}

不要在location块内使用ssl_certificate和ssl_certificate_key指令，请注意可能使用或可能不使用nginx指令的上下文。 SSLEngine ， ProxyPreserveHost和ProxyPassReverse是apache指令，请将其删除！ 在使用新配置重新加载nginx之前，请先使用nginx -t测试您的配置。
