记 nginx根据参数转对应地址

url：?ID=91be4706799c57a785ce74a11761e5db&PD=81222E0&VMC=QQQQ&MAC=461f28e27d5d612599cf6a870ff5e4a7

要求根据参数的VMC转发不同的地址

server {
listen 9001 ssl;
ssl_certificate /etc/nginx/ssl/server.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;
server_name xxxx;
location / {
if ( $query_string ~* .*&VMC=(33333|77777)&.* ) {
proxy_pass http://127.0.0.1:8802;
}

proxy_pass http://127.0.0.1:8801;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
#proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}

error_page 404 /404.html;
location = /40x.html {
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}

$query_string在nginx里代表参数

~* 代表后面是不分大小写的正则表达式

.*&VMC=(33333|77777)&.* 匹配url后面参数的正则表达式，根据vmc的不同跳转，等于33333或者77777的url跳到8802端口。
