如何修复 NGINX proxy_pass 以在端口 3000 上路由到我的应用程序？

Question

我遇到了 proxy_pass 的问题。一个请求进来。它被路由到我的应用程序运行的端口（3000），但总是返回 404。如果我向后端 api url 发出请求，那些返回 200。例如： www.mysite.com/api --- 返回 200 但： www.mysite.com/#/about --- 返回 404 www.mysite.com/ 或 www.mysite.com ---返回 404

如何让 nginx 为在端口 3000 上运行的应用程序提供服务？

nginx.conf

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;


        include /etc/nginx/mime.types;
        default_type application/octet-stream;



#       ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
#       ssl_prefer_server_ciphers on;


        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;
        gzip_disable "msie6";

          gzip_vary on;
          gzip_proxied any;
          gzip_comp_level 6;
          gzip_buffers 16 8k;
          gzip_http_version 1.1;
          gzip_types text/plain text/css application/json application/javascrip$

        ##
        # Virtual Host Configs
        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}

网站启用/默认

server {
        listen 80;
        server_name mysite.com www.mysite.com;
        return 301 https://$host$request_uri;

        location ~ /.well-known {
                allow all;
        }
}

#HTTPS
server{
listen 443;
ssl on;
server_name mysite.com www.mysite.com;
include snippets/ssl-mysite.com.conf;
include snippets/ssl-params.conf;


location / {
     expires max;
     proxy_pass http://127.0.0.1:3000;
     proxy_http_version 1.1;
     proxy_set_header Upgrade $http_upgrade;
     proxy_set_header Connection "Upgrade";
     proxy_set_header Host $http_host;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header X-Forward-Proto http;

}


}

由于某种原因，我无法让应用程序为公共目录提供服务...

希望上面的配置文件能说明我做错了什么。我真的很感谢你的帮助。如果您需要更多信息，请告诉我。

使用/api/ 端点在您的通话中尝试proxy_pass

location /api/ {
     ...
     proxy_pass http://127.0.0.1:3000;
     ...

}
