还是基于现有的扩展开发的，主要是尝试下

主要内容

包含类型定义以及，安装扩展使用

环境准备

详细介绍可以参考 https://www.cnblogs.com/rongfengliang/p/16210941.html

类型定义

resty-ipmatcher.d.ts

declare module  "resty.ipmatcher" {

    interface IpMatcher {

        match(ip:string|any):LuaMultiReturn<[true|false|Record<string,string>, string]>;

        match_bin(ip:any):LuaMultiReturn<[true|false|Record<string,string>, string]>;

    } 

    interface myIpmatcherConstructor {

        new: (this: void,ips:string[]) =>  LuaMultiReturn<[IpMatcher, string]>;

        new_with_value: (this: void,ips:Record<string,any>) => LuaMultiReturn<[IpMatcher, string]>;

        /** @noSelf */

        parse_ipv4(ip:stirng):true|false

        /** @noSelf */

        parse_ipv6(ip:stirng):true|false

    }

    var ipmatcher:myIpmatcherConstructor

    export = {

        ...ipmatcher

    }

}

基础镜像

FROM openresty/openresty:1.21.4.1rc3-1-alpine-fat

RUN /usr/local/openresty/luajit/bin/luarocks install hashids

RUN /usr/local/openresty/luajit/bin/luarocks install lua-resty-ipmatcher

使用

• nginx 配置

user root; 

master_process off;

worker_processes 1;

events {

    worker_connections  1024;

}

http {

    include       mime.types;

    default_type  text/html;

    lua_code_cache off;

    lua_package_path '/opt/lua/?.lua;;';

    real_ip_header     X-Forwarded-For;

    resolver 114.114.114.114;

    server {

       listen 80;

       charset utf-8;

       default_type text/html;

       location / {

           access_by_lua_file /opt/lua/acc.lua;

           content_by_lua_file /opt/lua/indexpage.lua;

        }

    }

}

ts 代码

import ipmatch = require("resty.ipmatcher")

let ips = {

    "192.168.17.101":{

       info:"demo"

    },

    "192.168.17.102": {

        info:"test"

    }

}

let ipv4 = ipmatch.parse_ipv4("127.0.0.1")

console.log(ipv4)

let [ip2, err2] = ipmatch.new_with_value(ips)

if (err2) {

    ngx.say(err2)

    ngx.exit(ngx.HTTP_INTERNAL_SERVER_ERROR)

}

let [ok2, errMsg2] = ip2.match("192.168.17.102")

if (errMsg2) {

    ngx.say(errMsg2)

    ngx.exit(ngx.HTTP_INTERNAL_SERVER_ERROR)

}

if (ok2) {

    if(typeof ok2 === "object") {

        ngx.say("is match ",ok2.info)

    }

    if(typeof ok2 ==="boolean") {

        ngx.say("is match ")

    }

}

• ts 配置

{

   "include": [

     "src/*/*"

    ],

   "compilerOptions": {

     "outDir": "./lua_code",

     "types": ["openresty-lua-types","lua-types/jit"],

     "lib": ["esnext","DOM"],

     "module":"commonjs",

     "target": "esnext",

     "skipLibCheck": true,                                /* Skip type checking all .d.ts files. */

     "esModuleInterop": true,

     "moduleResolution": "node",

     "forceConsistentCasingInFileNames": true,   

     "allowSyntheticDefaultImports": true,

     "strict": true

   },

   "tstl": {

     "noHeader": true,  

     "noImplicitSelf":true, 

     "buildMode": "library",

     "luaTarget": "JIT",

     "noResolvePaths":["hashids","resty.ipmatcher"]

   }

 }

效果

说明

TypeScriptToLua+openresty-lua-types 很方便，提供越多的类型定义，我们开发就越简单
