源码地址有文档那么复杂,在默认的配置文件加一个 location 就好

下面的是他的示例:

Example config for Nginx:

location /jackett {
proxy_pass http://127.0.0.1:9117;
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_set_header X-Forwarded-Host $http_host;
proxy_redirect off;
}
