Application on nginx reverse proxy redirects wrong
问题
问题：如何在我的应用程序内部（在nginx反向代理后运行）将重定向从应用程序的根目录改为服务器的根目录？
解决方案：您可以在应用程序中使用相对路径进行重定向，而不是绝对路径。在您的示例中，将重定向语句更改为以下内容：
func foo(w http.ResponseWriter, r *http.Request) {
http.Redirect(w, r, "/", http.StatusFound)
}
这将使重定向指向应用程序的根目录，而不是服务器的根目录。
英文:
I am running an nginx (0.7.67) as a reverse proxy and a golang application. The nginx server is configured as follows:
...
location /bar/ {
proxy_pass http://localhost:8088/;
proxy_redirect off;
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 https;
}
...
The source of my golang application (it doesn't make sense, only an example):
func root(w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "You reached root")
}
func foo(w http.ResponseWriter, r *http.Request) {
http.Redirect(w, r, "/", http.StatusFound)
}
func main() {
http.HandleFunc("/", root)
http.HandleFunc("/foo", foo)
http.ListenAndServe("localhost:8088", nil)
}
Problem: When I direct my browser to the URL of my application (https://domain.tld/bar/) I can see the text "You reached root". However, if I try to open https://domain.tld/bar/foo, I get redirected to https://domain.tld instead of https://domain.tld/bar. It seems that my application is redirecting to the root of the nginx server and not the application.
Question: How can I redirect from the inside of my application (running behind an nginx reverse proxy) to the root of my application, instead of the root of the server?

这是一个无法自动解决的问题，无论是哪种语言，甚至是PHP。像WordPress这样的应用程序会有一个设置来指定根目录。有些应用程序需要一个完整的URL（https://domain.tld/bar），或者只需要一个路径（/bar）。
无论哪种方式，你都需要创建一个设置，然后手动配置所有的重定向都基于该设置。你可以创建自己的重定向函数，这样每次重定向时就不需要实现它。
英文:
This is a problem that cannot be solved automatically in any language, even PHP. What applications such as wordpress do is have a setting to specify the root. Some applications require a full url (https://domain.tld/bar) or can just have a path (/bar).
Either way, you need to create a setting and then manually configure all redirects to be based from there. You can create your own redirect function so you don't need to implement it each time you do a redirect.
