Nginx根據url引數轉發


原文:https://www.cnblogs.com/wshenjin/p/13071392.html


線上一個需求,需要根據url引數的特定值做固定的轉發處理。

例如 http://api.example.com/?boole=1234&ment=abcd&plat=mix_a&dupl=1234
plat=mix_[a|b|c|d]時,轉發到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;
    }

另外一個需求,根據url引數的內容重寫
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後面跟上時間戳,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;
    }

另外一個需求,根據url引數返回不同的檔案
http://api.example.com/ooo/xxx/xxx.dat?game=ggg&plat=ppp
要求:請求*.dat檔案,引數game、plat必須存在,允許引數值為空,再引數值拼接出實際響應檔名,按xxx_${game}_${plat}.dat ==》xxx_${game}.dat ==》xxx.dat的順序查到,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=兩個引數必須存在
        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;
        }

        ##引數拼接出檔名,xxx_{game}_{plat}.dat ==》xxx_{game}.dat ==》xxx.dat的順序查到,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;
    }
