ruby-on-rails - Nginx Rails 5 HTTPS 重定向问题

Question

我在 Digital Ocean Ubuntu 16.04 Droplet 中托管了一个新的 Rails 5 应用程序。该设置使用 Nginx 和 Puma 作为应用程序服务器。我注意到重定向存在问题。

例如，如果我将重定向设置为 redirect_to services_path它尝试重定向到 https://jdeen.com,%20jdeen.com/services .

我相信这是一个 Nginx 配置问题，认为这与我的工作 Rails 3 应用程序非常相同，我不确定出了什么问题。当我进行简单的配置而不使用 SSL 时，它就可以工作。

非常感谢任何帮助。

Answer 1

该问题是由重复的 Host header 引起的，该 header 使用 proxy_set_header 指令设置了两次:

...
proxy_set_header Host $http_host;
proxy_redirect off;

proxy_set_header HOST $host;
...
