我正在尝试使用NGINX反向代理方法托管一个网站，我正在运行两个Node.js应用程序

Question

我的第一个应用程序在8080上运行，第二个应用程序在8081上运行，代码如下：

server {
    listen 80;
    server_name greatwallprojects.com;
    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
    location /pingtest {
            proxy_pass http://127.0.0.1:8081;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
        }
    }

我基本上会看到一个空白页面，一旦我尝试打开第二个位置页面，主页效果很好，但是http://greatwallprojects.com/pingtest加载一个空白页。如果反向代理方法有问题，我应该尝试其他方法吗？谁能指出问题？

Answer 1

我认为应该有效

upstream application_1 {
    server 127.0.0.1:8080;
}
upstream application_2 {
    server 127.0.0.1:8081;
}
server {
    listen 80;
    server_name greatwallprojects.com;
    location / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_pass http://application_1;
    }
    location ~* ^/pingtest$ {
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
            proxy_pass http://application_2;
        }
    }
