使用RPC和内部路由构建一个动态代理

正在进行中 (要求uWSGI 1.9.14，我们使用PyPy作为引擎)

第一步：构建你的映射函数

使用hostname作为映射 (你可以使用任何你需要的)

import uwsgi

def my_mapper(hostname):
    return "127.0.0.1:3031"

uwsgi.register_rpc('the_mapper', my_mapper)

将其保持为myfuncs.py

第二步：构建一个路由表

[uwsgi]
; enable the pypy engine
pypy-home = /opt/pypy
; execute the myfuncs.py file (the 'the_mapper' rpc function will be registered)
pypy-exec = myfuncs.py

; bind to a port
http-socket = :9090

; let's define our routing table

; at every request (route-run execute the action without making check, use it instead of --route .*) run the_mapper passing HTTP_HOST as argument
; and place the result in the MYNODE variable
route-run = rpcvar:MYNODE the_mapper ${HTTP_HOST}
; print the MYNODE variable (just for fun)
route-run = log:${MYNODE}
; proxy the request to the chosen backend node
route-run = http:${MYNODE}

; enable offloading for automagic non-blocking behaviour
; a good value for offloading is the number of cpu cores
offload-threads = 2
