多种协议的后端是否可以用balancer做动态upstream

easedays

Hello,

现在我这里nginx作为proxy要通过http, uwsgi和fastcgi和后端通信，按照春哥的例子，目前实现http的动态upstream没有问题。

worker_processes 1;

error_log logs/error.log info;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

lua_package_path 'lua/lua-resty-http/lib/?.lua;lua/?.lua;;';

init_worker_by_lua_file lua/containers.lua;

upstream backend {

server 0.0.0.1; # just an invalid address as a place holder

balancer_by_lua_file lua/balancer.lua; # balancing policy

keepalive 65; # connection pool

}

server {

listen 8080;

location / {

proxy_pass http://backend/;

}

server {

listen 8081;

location / {

content_by_lua_file lua/content.lua;

}

可是我如何根据请求的信息（Host和URI）来决定该用何种协议和后端通信呢，而不仅仅是proxy_pass？

Thanks

用location段做协议区分

location / {

content_by_lua_block {

if ngx.var.request_uri == '/fastcgi' then

ngx.exec('/@fastcgi')

else

ngx.exec('@http')

end

}

location @http {

proxy_pass http://backend/;

}

location @fastcgi {

fastcgi_pass fastcgi_backend;

}
