Nginx根据url中的path动态转发到upstream的实现

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;
}

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;                
}
