skipper 对于lua 脚本的支持是通过gopher-lua,支持基本上大部分的lua特性
说明:项目使用docker-compose 运行
环境准备
- docker-compose 文件
version: "3"
services:
skipper:
image: dalongrong/skipper:latest
ports:
- "9090:9090"
- "9911:9911"
volumes:
- "./router.eskip:/router.eskip"
- "./app.lua:/app.lua"
command: skipper -enable-ratelimits -enable-prometheus-metrics -routes-file router.eskip
g:
image: grafana/grafana
ports:
- "3000:3000"
web:
image: nginx
ports:
- "8099:80"
p:
image: prom/prometheus
volumes:
- "./prometheus.yml:/etc/prometheus/prometheus.yml"
ports:
- "9091:9090"
- router 配置
hello: Path("/report/**") ->compress("text/html")-> corsOrigin()->setResponseHeader("TOKEN","dalongdemo")->responseCookie("test-session", "abc", 31536000)->
setRequestHeader("TOKEN","dalongdemo")-> "http://10.10.17.21:9000/report";
app: Path("/**") -> lua("/app.lua", "myparam=foo", "other=bar") -> "http://10.15.0.80"
- lua 脚本
在response 阶段,添加header
function request(ctx, params)
-- ctx.serve({
-- status_code=302,
-- header={
-- location="http://www.baidu.com/",
-- },
-- })
ctx.request.header["user_token"]="request_token"
end
function response(ctx, params)
ctx.response.header["lua_token"]="dalongdemo";
end
运行&&测试
- 启动
docker-compose up -d
- 测试
说明
目前已经内置了一些可用的模块 http json url base64,同时对于lua 标准模块也支持,模块查找规则
比如 require("mod")
/mod.lua, /usr/local/share/lua/5.1/mod.lua and /usr/local/share/lua/5.1/mod/init.lua)
