nginx在多层服务器代理接口地址的应用

场景：访问接口地址 --> A服务器 --> A服务器反向代理到B服务器 --> B服务器反向代理到C服务器 --> 获取结果并返回

1、A 服务器反向代理配置

nginx 复制代码

server {
    listen 4832;
    server_name _;
    location / {
        proxy_pass http://192.168.25.6:4832/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

    location /file/device/ {
        proxy_pass http://192.168.25.6:9500/energy/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    #冷水机接口-鉴权
    location /dashboard-lsj-8888/ {
        proxy_pass http://192.168.25.6:8001/dashboard-lsj-8888/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    #冷水机接口-数据
    location /dashboard-lsj-90/ {
        proxy_pass http://192.168.25.6:8001/dashboard-lsj-90/;
        proxy_set_header accessToken $http_accesstoken;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

2、B 服务器反向代理配置

nginx 复制代码

location /dashboard-lsj-8888/ {
        proxy_connect_timeout 300s;
        proxy_read_timeout 1800s;
        proxy_send_timeout 600s;
        proxy_set_header   Host             $http_host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto  $scheme;
        proxy_pass http://192.168.53.171:8888/;
}


location /dashboard-lsj-90/ {
        proxy_connect_timeout 300s;
        proxy_read_timeout 1800s;
        proxy_send_timeout 600s;
        proxy_set_header   Host             $http_host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto  $scheme;
        proxy_set_header accessToken $http_accesstoken;
        proxy_pass http://192.168.53.171:90/;
}
