nginx - 基于 http_accept_language 的 docker nginx 重定向

Question

我有一个静态网站，我想根据浏览器语言创建重定向。该网站使用 nginx 在 docker 中运行，构建如下：

nginx.conf：

user nginx;
worker_processes 4;
error_log /dev/stderr info;
pid       /var/run/nginx.pid;

events {
    worker_connections 1024;
}


http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;
    access_log /dev/stdout;
    sendfile on;
    keepalive_timeout 65;

    include /etc/nginx/conf.d/*.conf;

    root /usr/share/nginx/my-app;

    map $http_accept_language $myindex {
        default index.html;
        ~*^fr.*  index.fr.html;
    }

    server {
        location / {
            rewrite .* $myindex;
        }
    }

}

默认.conf：

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    server_name _;
    root /var/www;
    index index.html; 

    location / {
        try_files $uri $uri/ /index.html$is_args$args;
    }
}

dockerfile

# nginx
FROM nginx:1.17.5-alpine

COPY src /var/www
COPY nginx.conf /etc/nginx/nginx.conf
COPY conf.d /etc/nginx/conf.d
EXPOSE 80

一旦我转到本地主机，就会出现以下问题：en -> index.html en -> index.html（预期：index.de.html）
