在Nginx中，有一些高级场景，需要根据url中的path参数，动态转发到不通的upstream
场景1
/svr1/xxxx?yyy 转发到 svr1:8080/xxxx?yyy
/svr2/xxxx?yyy 转发到 svr2:8080/xxxx?yyy
配置如下：
location ~* /(srv[1-9]+)/(.*)$ {
allow all;
proxy_pass http://$1/$2$is_args$args;
proxy_set_header Host $host;
proxy_set_header x-forwarded-for $forwarded_addr;
}
upstream srv1 {
server srv1-ip:8080;
}
upstream srv2 {
server srv2-ip:8080;
}
场景2
svc1下有3个对等服务srv1,2,3，/svc1/xxxx?yyy 转发到，srv1/2/3:8080/xxxx?yyy
svc2下有3个对等服务srv4,5,6，/svc2/xxxx?yyy 转发到，svr4/5/6:8080/xxxx?yyy
location ~* /(svc[1-9]+)/(.*)$ {
allow all;
proxy_pass http://$1/$1/$2$is_args$args;
proxy_set_header Host $host;
proxy_set_header x-forwarded-for $forwarded_addr;
}
upstream svc1 {
server srv1:8080;
server srv2:8080;
server srv3:8080;
}
upstream svc2 {
server srv3:8080;
server srv4:8080;
server srv5:8080;
}
