openresty 使用cuid 类库生成短链接id
cuid 是一个不错的id 生成算发，类似的有shortid 、hashid
演示使用lua 包集成openresty 做测试
使用docker-compose 运行
dockerfile
FROM openresty/openresty:alpine-fat RUN apk add --no-cache curl perl RUN /usr/local/openresty/luajit/bin/luarocks install cuid EXPOSE 80 COPY nginx.conf usr/local/openresty/nginx/conf/
docker-compose file
version: "3"
services:
id:
build: .
image: dalongrong/cuid-openresty
ports:
- "8080:80"
nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
gzip on;
real_ip_header X-Forwarded-For;
real_ip_recursive on;
server {
listen 80;
server_name localhost;
charset utf-8;
location / {
root html;
index index.html index.htm;
}
location /id {
default_type text/html;
content_by_lua_block {
local cuid = require("cuid")
local id = cuid.generate ( )
local slug = cuid.slug ( )
ngx.say("<div> shortid "..slug.."</div>".."<div>long id"..id.."</div>")
}
}
location /alert {
default_type text/html;
content_by_lua_block{
ngx.say([[<script>alert("error")</script>]])
}
}
location /ip {
default_type text/html;
content_by_lua_block{
ngx.say(ngx.var.remote_addr)
}
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
构建&&运行
- 构建
docker-compose build
- 运行
docker-compose up -d
- 访问
open http://localhost:8080/id
- 效果
