KONG 可视化管理及接口访问

1 Konga UI基本使用
一般访问地址:

http://192.168.1.70:8080

1.1 Step1:创建upstream
KONG 可视化管理及接口访问

1.1.1 【样例】
Name=>VCSAPI_SERVER

Slot=>1000

1.2 Step2:配置upstream target

KONG 可视化管理及接口访问

1.2.1 【样例】
多个节点,配置多个target即可。

Target=>192.168.10.30:8080

Weight=>100

1.3 Step3:添加API Service

KONG 可视化管理及接口访问

1.3.1 【样例】
Name=>VCSAPI-SERVICE

HOST=>VCSAPI_SERVER(注:对应upstream name)

port=>80

path=>/vcs(注:对应目标转发路径,根据实际部署context调整)

1.4 Step4:配置API路由

KONG 可视化管理及接口访问

1.4.1 【样例】
Service=>VCSAPI-SERVICE

paths=>/vcs(注:客户端请求路径,根据实际部署调整)

Preserve Host:true 客户端请求的HOST通过kong透传到上游服务。

Strip path:true,是否删除匹配的url前缀字符。

1.5 Step5:配置consumer

1.5.1 【样例】
username=>icfw

1.6 Step6:配置用户JWT认证

1.6.1 【样例】
End-Point

Key(iss)

Secret

icfw

qD8WKwxQWQZVcdhc05yzqDpRLZMQjMH8

RE1NEaUcWBQFTj0Mxip1hy1PsFBoCVez

注:key secret创建时,可不用输入,由系统自动生成随机字符串。

1.7 Step7:配置服务JWT插件

KONG 可视化管理及接口访问

1.7.1 【样例】
Apply to=>VCSAPI_SERVICE,选择service->plugins->jwt

Key_claim_name=>iss,固定写法 ,对应key

Claims_to_verify=>exp,固定写法,jwt token过期时间,unix时间数值串.(可选)

1.7.2 Jwt token 生成
通过访问https://jwt.io/,生成JWT TOKEN

1.7.3 客户端调用,设置HTTP头(Authorization ):Bearer jwtkoken字符串。

1.8 Step7:配置限流插件

KONG 可视化管理及接口访问

1.8.1 【样例】

Apply to service=>,根据不同场景,选择servcie即可

policy=>redis,限流策略方式,此处用redis

limit_by =>ip,限流维度,此处用以ip限流

second=>10,控制在每秒并发10以内(单ip访问)

redis_password=>redis配置密码

redis_host=>192.168.1.203

redis_database=>0,选择数据库序号,此处为0

配置限流插件,注意数据库PG中的时间,是否与北京时间同步。因为是通过时间事件控制的,如果时间点不对,限流尽管配置了,也不会触发的。

1.9 Step8:服务降级实现
通过Kong实现服务降级思路如下:

1> 梳理出需要走服务降级的接口

2> 按降级时返回数据进行归类,相同的路由到同一个URI(kong配置预先配置的)

3> 访问端走网关的不同路由配置

通过Kong的请求中断插件实现服务降级,减少对后台服务器(api等)的访问压力。

按理已经开启限流策略,可以避免大部分恶意压力***,但不排除模拟真实应用场景的***方式,可以通过服务降级做为补充方案。

1.9.1 【样例】
Apply to=>service,根据不同场景选择指定的service

Status_code=>200,自定义,一般是200

Content_type=>application/json; charset=utf-8,自定义

Response body=>{"result": {},"code": 200,"message": "OK" },需要开发整理
