Zuul路由網(wǎng)關(guān)
概述
Zuul包含了對(duì)請(qǐng)求的路由和過(guò)濾兩個(gè)主要的功能辰如，其中路由的功能是負(fù)責(zé)將外部請(qǐng)求轉(zhuǎn)發(fā)到具體的微服務(wù)實(shí)例上，是實(shí)現(xiàn)外部訪問統(tǒng)一入口的基礎(chǔ)而過(guò)濾功能是負(fù)責(zé)對(duì)請(qǐng)求的處理過(guò)程進(jìn)行干預(yù)褐奥，是實(shí)現(xiàn)請(qǐng)求校驗(yàn)杆故，服務(wù)聚合等功能的基礎(chǔ)洛二，Zuul和Eureka進(jìn)行整合舱沧，將Zuul自身注冊(cè)近Eureka服務(wù)治理的應(yīng)用妹沙，同時(shí)從Eureka中獲取其他微服務(wù)的消息，也及時(shí)以后的訪問服務(wù)都是通過(guò)Zuul跳轉(zhuǎn)后獲得熟吏， 注意的是Zuul服務(wù)最終還是會(huì)注冊(cè)近Eureka中

三個(gè)集群，一個(gè)服務(wù)提供類microservicecloud-provider-dept-8001牵寺，一個(gè)路由
測(cè)試
不使用路由：http://localhosat:8001/dept/get/2
使用路由：http://myzuul.com:9527/microservicecloud-dept/dept/get/2
Zuul路由訪問映射
在前面的測(cè)試中我們可以使用http://myzuul.com:9527/microservicecloud-dept/dept/get/2訪問我們的接口悍引，這樣就暴露我們的微服務(wù)名稱，需要做安全加固帽氓，就用到了路由訪問映射趣斤，修改路由項(xiàng)目的yml文件,添加 mydept.path: /mydept/**
zuul:
#ignored-services: microservicecloud-dept #忽略真實(shí)地址，只讓虛擬地址訪問
prefix: /luo #訪問地址前綴
ignored-services: "*"#忽略真實(shí)地址杏节，只讓虛擬地址訪問
routes:
mydept.serviceId: microservicecloud-dept ##真實(shí)地址
mydept.path: /mydept/** # 虛擬地址
