nginx

Question

我是一名前端开发人员，上次尝试过我的nginx配置，但是工作正常。以下是配置：

server {
    listen       80;
    server_name  localhost;
    access_log  /var/log/nginx/localhost.access.log;
    location / {
             #By default route to node.js running on localhost:9000 port
             proxy_pass http://localhost:9000;
             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;
    }
    #currently only one server but will have to redirect to n hosts based on a parameter
    location /hosts.json {
      proxy_pass      http://app-host.net:3000;
    }
    #currently only one server but will have to redirect to n hosts based on a parameter
    location /hosts/ {
      proxy_pass      http://app-host.net:3000;
    }
}

现在，我需要根据参数重定向到4个不同的服务器。即如果城市是Bangalore，我需要重定向到bangalore.corp.net:3000，如果城市是NewYork，那么我需要重定向到newyork.corp.net:3000，依此类推。

我有点期待：

location /app1/hosts/ {
      proxy_pass      http://app1-host.net:3000;
    }
#But the proxy pass should point to http://app1-host.net:3000/hosts and not http://app1-host.net:3000/app1/hosts

我们如何在nginx配置文件中处理此类代理传递。请告诉我。

Answer 1

您有/app1/hosts/foo表格的网址，该网址应映射到http://app1-host.net:3000/hosts/foo。可以通过在proxy_pass指令中附加一个URI来实现，该指令的作用类似于alias。

location /app1/hosts/ {
  proxy_pass http://app1-host.net:3000/hosts/;
}
