如果 url 中缺少尾部斜杠，nginx 不會將請求傳遞給節點服務器

Question

我已經用 wordpress 設置了 nginx，它工作正常。 現在我創建了一個反應應用程序，它在端口 3000 中運行。如果某個位置匹配，我希望我的 nginx 服務器將請求傳遞給反應服務器。 下面是 nginx 配置與 wordpress 和反應應用程序。

    listen 80;
    server_name aaroogya.org;
    return 301 https://aaroogya.org$request_uri;
}
server {
#        listen 80;

       
    root /var/www/wordpress;
        index index.php index.html index.htm index.nginx-debian.html;
        server_name aaroogya.org www.aaroogya.org;
    #location = /favicon.ico { log_not_found off; access_log off; }
        #location = /robots.txt { log_not_found off; access_log off; allow all; }
    #server_name testbed2.covidhelp.in;

    location /covidhelp{
#root /var/www/;
#   index index.html;
        add_header Access-Control-Allow-Origin http://127.0.0.1:3000/;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_set_header X-NginX-Proxy true;
                proxy_pass http://127.0.0.1:3000/ ;
                proxy_redirect off;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_redirect off;
                proxy_set_header X-Forwarded-Proto $scheme;
    }




     location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
            expires max;
            log_not_found off;
        }
        location / {
                #try_files $uri $uri/ =404;
        try_files $uri $uri/ /index.php$is_args$args;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        }

        location ~ /\.ht {
                deny all;
        }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/aaroogya.org/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/aaroogya.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


}

當我訪問https://www.aaroogya.org/covidhelp/

它將請求重定向到反應服務器，但是當我嘗試加載所有 static 文件（如 bundle.js）時，它無法正常工作。 例如https://www.aaroogya.org/covidhelp/static/js/main.chunk.js - 不工作的例子https://www.aaroogya.org/covidhelp/static/js/main.chunk.js/ - 添加了一個斜杠，它的工作正常。

Answer 1

我已經通過 2 個步驟解決了這個問題。

1. 檢查/var/log/nginx/error.log

connect() failed(111: Connection refused) while connecting to upstream, client: * .*.*.*, server: * .*.*.*, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8000/", host: "*.*.*.*"

即使我在 nginx conf 文件中將上游設置為127.0.0.1:3000 ，上游仍然是127.0.0.1:8000 。

2. 將服務器 127.0.0.1:8000 替換為/etc/nginx/conf.d/virtual.conf中的服務器127.0.0.1:3000並重新啟動 nginx。

以下：

server {
    listen       80;
    server_name  SERVER_IP_ADDRESS;

    location / {
        proxy_pass http://127.0.0.1:3000;
    }
}

然后：

sudo /etc/init.d/nginx restart 

最后，它沒有 502 錯誤。
