本文介绍如何使用Nginx配置文件实现基于URL后缀的请求转发策略，将不同URL后缀的请求定向到特定的服务器。

需求让Nginx跟据请求的url不同，而转发到不同的server上
举例：
url http://127.0.0.1/json/0769/
url http://127.0.0.1/json/0734/
需求把url后缀为0769的请求转发到server1， url 后缀为0734的请求转发到server1

nginx.conf实现代码

worker_processes 2;

#error_log /var/log/nginx/error.log;
#pid /var/run/nginx.pid;

events {
    worker_connections 1024;
    use epoll;
}

http {
    charset utf-8;

    map $zone $up_stream {
    	^~0769	frontends_0769;
    	^~0734	frontends_0734;        
    	default	frontends_0769;
    }

    # Enumerate all the Tornado servers here
    upstream frontends_0769 {
        server 127.0.0.1:3333;
        #server 127.0.0.1:3334;
        #server 127.0.0.1:3335;
        #server 127.0.0.1:3336;
    }
    
    upstream frontends_0734 {
        server 127.0.0.1:3334;
        #server 127.0.0.1:3334;
        #server 127.0.0.1:3335;
        #server 127.0.0.1:3336;
    }    

    include mime.types;
    default_type application/octet-stream;

    #access_log /var/log/nginx/access.log;

    keepalive_timeout 65;
    proxy_read_timeout 200;
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1000;
    gzip_proxied any;
    gzip_types text/plain text/css text/xml
               application/x-javascript application/xml
               application/atom+xml text/javascript;

    # Only retry if there was a communication error, not a timeout
    # on the Tornado server (to avoid propagating "queries of death"
    # to all frontends)
    proxy_next_upstream error;

    server {
        listen 8089;

        location / {
            proxy_pass_header Server;
            proxy_set_header Host $http_host;
            proxy_redirect off;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
            #proxy_pass http://frontends;
            #if ( $request_uri ~* /json/(\d\d\d\d)\d+/ ) {
            #    set $zone $1;
            #    proxy_pass http://frontends_$zone;
            #}
            if ( $request_uri ~ ^/json/(\d+)/$ ) {
                set $zone $1;
                proxy_pass http://$up_stream;
            }            
            
        }
    }
}
