一、環(huán)境部署
eureka 在本地的url
http://eureka.best.net:8761/
獲取在eureka注冊的所有服務(wù)
http://eureka.best.net:8761/eureka/apps/
獲取在eureka注冊的MY-SERVICE服務(wù)的所有節(jié)點
http://eureka.best.net:8761/eureka/apps/MY-SERVICE
二转捕、服務(wù)發(fā)現(xiàn)
1祭衩、發(fā)送接口請求，獲取服務(wù)節(jié)點信息
http://eureka.best.net:8761/eureka/apps/MY-SERVICE
報文結(jié)構(gòu)缕坎，有3個節(jié)點，所以就有3個instance
報文結(jié)構(gòu)
一個instance 報文內(nèi)容

}
解析報文，
ipAddr 字段獲取 ip 郊丛，status 字段獲取狀態(tài)李请，homePageUrl 字段獲取請求url（包含ip和端口），
instance.get(i).get("metadata").get("envflag") 厉熟，獲取節(jié)點別名（泳道標(biāo)簽）
