Nginx 将特定子域重定向到特定位置

Question

我希望这样，当用户键入

task-manager.example.com

时，他们会自动重定向到

location /api/ 

，而无需键入

task-manager.example.com/api

的完整路径。只有

task-manager.example.com

应该被重定向到

location /api/ 

对于

example.com

和

www.example.com

，无论用户是否键入

location /

，我都希望将所有请求定向到

example.com/api

。对

example.com/api

或

www.example.com/api

的任何请求都应自动重定向到

example.com/

或

www.example.com/

.

可以配置 Nginx 来实现这个功能吗？

这是我当前的配置：

server
{
    server_name example.com www.example.com task-manager.example.com;

    location /
    {
        # Frontend application
        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 $scheme;

        proxy_pass http://localhost:9091;
    }

    location /api/
    {
        # Backend application
        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 $scheme;

        proxy_pass http://localhost:9090;
    }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server
{
    if ($host = www.example.com) {
        return 301 https://$host/;
    } # managed by Certbo


    if ($host = example.com) {
        return 301 https://$host/;
    } # managed by Certbo


    if ($host = task-manager.example.com) {
        return 301 https://$host/api;
    } # managed by Certbo


    listen 80 default_server;
    listen [::]:80 default_server;
    server_name example.com www.example.com task-manager.example.com;
    return 404; # managed by Certbot
