建立/激活链接
使用Kong的第一步是激活链接，登录Kong管理后台，找到 Connections，把Kong的Api链接上,因为我本地的端口进行了映射，所以需要找到Docker的network 上的ip，进行绑定, ip 地址 172.19.0.3

docker network inspect gateway_net"dcb524ba2b30e16e6453b9159ceb4edb642c42ea84dd00ee4ce1cd158737a118": { "Name": "kong-ee", "EndpointID": "4bcabe9c26cb082ba55f95ff9257b5cc3ff57d6f80059ac76501c7bd7eeba09f", "MacAddress": "02:42:ac:13:00:03", "IPv4Address": "172.19.0.3/16", "IPv6Address": ""},配置负载均衡
上图是Kong实现负载均衡的流程图，Kong的使用非常简单，使用 Http Api的方式添加：
1.添加upstreams
POST http://127.0.0.1:9001/upstreams{ "name":"audio-upstream"}2.添加Target
POST http://127.0.0.1:9001/upstreams/audio-upstream/targets{ "target":"127.0.0.1:9502", "weight":100}192.168.251.2
3.配置Service
POST http://127.0.0.1:9001/services{ "name":"audio-service", "host":"audio-upstream"}4.配置Route
配置Route的时候，paths参数必须以/开头
POST http://127.0.0.1:9001/services/audio-service/routes{ "name":"audio-service-route", "paths[]":"/audio"}认证
1.Basic认证
用户名密码的认证方式，在Konga的Consumers添加就可以了
POST http://127.0.0.1:9001/routes/audio-service-route/plugins{ "name":"basic-auth", "config.hide_credentials":"true"}2.jwt认证
1.添加jwt认证操作组件操作
POST http://127.0.0.1:9001/services/audio-service/plugins{ "name":"jwt"}2.设置jwt加密方式，参数说明：
algorithm : 加密方式key ：Consumers里面设置的keysecret：自定义32位的加密串POST http://127.0.0.1:9001/consumers/test/jwt{ "algorithm":"HS256", "key":"test", "secret":"UmVZkyvSPOiGgVW2B1g1uhkM0tSPl5o3"}限流
相较于权限验证，Kong的限流就比较简单了许多，Kong采用计数器的形式进行限流。
config.minute :没分5次config.limit_by：根据ip限流POST http://127.0.0.1:9001/services/audio-service/plugins{ "name":"rate-limiting", "config.minute":5, "config.limit_by":"ip"}黑/白名单
Kong的黑/白名单功能是根据限制ip实现的。
POST http://127.0.0.1:9001/services/audio-service/plugins{ "name":"ip-restriction", "config.deny":"127.0.0.1"}标签：
