案例描述

以以上配置为例，假设消费者位于标记为 CENTER 的 na62 机房，请求上下文中的 user_unit 属于 CENTER

那么我们有以下路由流程

当我们经过 UnitRouter 时，地址被分成四个部分

+CENTER

10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
  • UNSH
10.0.0.4:12200?_p=hessian2&APP=demo&st=et12&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSH
10.0.0.5:12200?_p=hessian2&APP=demo&st=et12&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSH
  • UNSZ
10.0.0.6:12200?_p=hessian2&APP=demo&st=SA128&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSZ
10.0.0.7:12200?_p=hessian2&APP=demo&st=SA128&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSZ
  • UNZBMIX
10.0.0.8:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.9:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.10:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX

由于 user_unit 属于 CENTER，我们选择 CENTER 部分作为 MachineRoomRouter 的地址输入，即

CENTER

10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

第二步，MachineRoomRoute 可以分成五个部分

na61

10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

na610

10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

na62

10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.8:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.9:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.10:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX

na620

10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
fallback
10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER


10.0.0.4:12200?_p=hessian2&APP=demo&st=et12&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSH
10.0.0.5:12200?_p=hessian2&APP=demo&st=et12&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSH

10.0.0.6:12200?_p=hessian2&APP=demo&st=SA128&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSZ
10.0.0.7:12200?_p=hessian2&APP=demo&st=SA128&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSZ

10.0.0.8:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.9:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.10:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX

由于消费者在 na62 机房发起调用，所以匹配

       - name: na62-samesite-route // Send traffic from na62 computer room to na62 computer room
         match:
          - sourceables:
             sigma.ali/site: na62
         route:
          -destination:
             host: demo
             subset: na62

此规则，然后，选择

na62

10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.8:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.9:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
10.0.0.10:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX

UnitRouter 到 MachineRoomRouter 的输入是

CENTER

10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

两者的交集结果是

 10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

此结果将用作下一条路由的输出，重复之前的操作；

如果此路由规则已结束，则调用的地址将是

10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
