我有 React app Node JS 后端和 nginx。我已经获得证书并通过 Certbot 安装它。
我的应用程序发出获取和发布请求，但为此我需要设置 proxy_pass 设置。
我的服务器块文件：
server {
root /var/www/nikolsoborsocial/html;
index index.html index.htm index.nginx-debian.html;
server_name nikolsoborsocial nikolsoborsocial.org
www.nikolsoborsocial.org;
location / {
try_files $uri $uri/ =404;
}
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/nikolsoborsocial.org/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/nikolsoborsocial.org/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = www.nikolsoborsocial.org) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = nikolsoborsocial.org) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
listen [::]:80;
server_name nikolsoborsocial nikolsoborsocial.org
www.nikolsoborsocial.org;
return 404; # managed by Certbot
}
我需要添加 proxy_pass 设置吗？
proxy_pass http://localhost:3000; include proxy_params;
如果我将其放入 433 服务器位置，插入 try_files $uri $uri/ =404; 我的 React 应用程序无法加载，并且我在浏览器中收到 Cannot GET / 错误。
您设置 nginx 配置文件以在“location /”服务器块中提供 React 文件。
因此，如果您尝试在“location /”块中添加 proxy_pass 设置，它将覆盖提供反应文件的代码。 Nginx 会将请求代理到运行在 localhost:3000 上的后端服务器。
如何解决此问题？
您必须在后端服务器中为此请求提供文件，或添加新的位置块。
这是添加新位置块的示例
server { root /var/www/nikolsoborsocial/html; index index.html index.htm index.nginx-debian.html; server_name nikolsoborsocial nikolsoborsocial.org www.nikolsoborsocial.org; location / { try_files $uri $uri/ =404; } # Proxy Pass settings location /app { proxy_pass http://localhost:3000; include proxy_params; } # SSL configuration listen [::]:443 ssl ipv6only=on; listen 443 ssl; ssl_certificate /etc/letsencrypt/live/nikolsoborsocial.org/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/nikolsoborsocial.org/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; }
