线上一个需求,需要根据url参数的特定值做固定的转发处理。

例如 http://api.example.com/?boole=1234&ment=abcd&plat=mix_a&dupl=1234
plat=mix_[a|b|c|d]时,转发到http://api-bgp.example.com

    location / {
         proxy_redirect off;
         proxy_set_header   Host             api-bgp.example.com;
         proxy_set_header   X-Real-IP        $remote_addr;
         proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
         if ( $query_string ~  "\bplat=mix_(a|b|c|d)\b" ){
             proxy_pass $scheme://1.1.1.1:$server_port;
         }
         index index.php index.html index.htm;
    }

另外一个需求,根据url参数的内容重写
http://api.example.com/ooo/xxx/index.php?version=1s1234&boole=1234&ment=abcd ---> http://api.example.com/ooo/xxx/rule.php?version=1s1234&boole=1234&ment=abcd
version=1sxxxx是1s后面跟上时间戳,例如:version=1s1598521028

    location = /ooo/xxx/index.php {
        if ( $query_string ~ "\bversion=1s(\d+)\b" ) {
            rewrite /ooo/xxx/index.php /ooo/xxx/rule.php  last;
        }
        include fcgi.conf;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        expires off;
    }

另外一个需求,根据url参数返回不同的文件
http://api.example.com/ooo/xxx/xxx.dat?game=ggg&plat=ppp
要求:请求*.dat文件,参数game、plat必须存在,允许参数值为空,再参数值拼接出实际响应文件名,按xxx_${game}_${plat}.dat ==》xxx_${game}.dat ==》xxx.dat的顺序查到,存在就返回:

    location ~ /ooo/xxx/.*\.dat$ {
        set $dat "";
        set $game "";
        set $plat "";
        if ( $uri ~ "/ooo/xxx/(.*)\.dat$"){
            set $dat $1;
        }
        #取反匹配,要求game= plat=两个参数必须存在
        if ( $query_string !~ "(\bgame=.*&plat=.*)|(\bplat=.*&game=.*)" ){
            return 404;
        }
        if ( $query_string ~ "\bgame=(\w+)\b" ){
            set $game $1;
        }
        if ( $query_string ~ "\bplat=(\w+)\b" ){
            set $plat $1;
        }

        ##参数拼接出文件名,xxx_{game}_{plat}.dat ==》xxx_{game}.dat ==》xxx.dat的顺序查到,存在就返回
        if ( -f "/data/web/t/ooo/xxx/${dat}_${game}_${plat}.dat" ) {
           rewrite /ooo/xxx/(.*) /ooo/xxx/${dat}_${game}_${plat}.dat break;
        }
        if ( -f "/data/web/t/ooo/xxx/${dat}_${game}.dat" ) {
           rewrite /ooo/xxx/(.*) /ooo/xxx/${dat}_${game}.dat break;
        }
        rewrite /ooo/xxx/(.*) /ooo/xxx/${dat}.dat break;
    }
