我有 React app Node JS 後端和 nginx。我已經獲得證書並透過 Certbot 安裝它。
我的應用程式發出獲取和發布請求，但為此我需要設定 proxy_pass 設定。
我的伺服器區塊檔案：
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
}
我需要新增 proxy_pass 設定嗎？
proxy_pass http://localhost:3000; include proxy_params;
如果我將其放入433 伺服器位置，插入try_files $uri $uri/ =404; 我的React 應用程式無法加載，並且我在瀏覽器中收到Cannot GET / 錯誤。
您設定 nginx 設定檔以在「location /」伺服器區塊中提供 React 檔案。
因此，如果您嘗試在「location /」區塊中新增 proxy_pass 設定，它將覆蓋提供反應檔案的程式碼。 Nginx 會將請求代理程式到執行在 localhost:3000 上的後端伺服器。
如何解決此問題？
#您必須在後端伺服器中為此請求提供文件，或新增新的位置區塊。
這是新增位置區塊的範例
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; }
