flask - nginx rewrite routing

Question

Configuration of nginx + gunicorn + flask. Now I map the /demo route to port 8088. How to rewrite the route {code...} But if I write it like this, localhost/demo still doesn’t work. What should I do?

伊谢尔伦 · Answer

Visit my_server/demo and try?

高洛峰 · Answer

rewrite ^/demo/(.*)$ / last;

changed to

rewrite ^/demo/(.*)$ / break;

last会对server块重新发起请求，break则使用当前location

If you say you want

/demo is proxy to 8088, /demo/xx is proxy to 8088/xx

If

, you may need to do this:

server {
    listen 80;
    server_name my_server;
    
    location / {
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass http://127.0.0.1:8088;
                        
        rewrite ^/demo/(.*)$ / break;
    }
}

But this can be processed directly in your background program, because the result is that accessing /demo/xx has the same effect as accessing /xx
