Nginx根据url中的path动态转发到upstream

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;                               
}
