場景：使用Wi-Fi連接的內(nèi)網(wǎng)web 服務

構思&準備

• 需要有雙網(wǎng)卡的電腦或服務器一臺
• 連接資源寶發(fā)射的Wi-Fi，并獲取當前電腦內(nèi)網(wǎng)IP (192.168.0.144)
• 已知資源寶Wi-Fi訪問地址為固定的：192.168.88.100
• 本機電腦連接資源寶Wi-Fi則可訪問資源寶，用nginx代理則可實現(xiàn)局域網(wǎng)訪問本地，間接訪問到資源寶web服務地址

nginx配置

server
    {
        listen 80;
        server_name 192.168.0.144;

        location / {
            proxy_pass http://192.168.88.100/;
            proxy_redirect off;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host:$server_port;
            proxy_cookie_domain 192.168.88.100 192.168.0.144;
            client_max_body_size 10m;
            client_body_buffer_size 128k;
            proxy_connect_timeout 90;
            proxy_send_timeout 90;
            proxy_read_timeout 90;
            proxy_buffer_size 4k;
            proxy_buffers 4 32k;
            proxy_busy_buffers_size 64k;
            proxy_temp_file_write_size 64k;
        }
    }

重啟nginx后發(fā)現(xiàn)該web網(wǎng)站存在回調(diào)判斷《竦迹回調(diào)端口為10001，且圖片、視頻資源的端口為9090

修改思路

• 無法修改源碼归敬，則只能通過ngnix替換

用的的模塊

• http_substitutions_filter_module
  修改后nginx配置

server
    {
        listen 80;
        server_name 192.168.0.144;

        location / {
            proxy_pass http://192.168.88.100/;
            proxy_redirect off;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host:$server_port;
            proxy_cookie_domain 192.168.88.100 192.168.0.144;
            client_max_body_size 10m;
            client_body_buffer_size 128k;
            proxy_connect_timeout 90;
            proxy_send_timeout 90;
            proxy_read_timeout 90;
            proxy_buffer_size 4k;
            proxy_buffers 4 32k;
            proxy_busy_buffers_size 64k;
            proxy_temp_file_write_size 64k;

            #替換之前 host
            subs_filter '192.168.88.100:9090' '192.168.0.144:9090';
            subs_filter "host + '/dbStatus/'" "'http://192.168.0.144:10001/dbStatus/'";
        }
    }

其他代理配置

server
{
    listen 9090;
    server_name 192.168.0.144;
    location /{
        proxy_pass http://192.168.88.100:9090;
    }
}

server
{
    listen 10001;
    server_name 192.168.0.144;
    location /{
        proxy_pass http://192.168.88.100:10001;
    }

}
