合宿

TL;DR

Lambdaはいいぞ

やろうとしたこと

[done]botの受け側の整備
ua出す
[done]botをキックする奴
[done]apigateway
curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"to": "u6f27bae0d2XXXXXXXXXXXXXXXXXXXXXX", "text":"あああ"} https://xxxxxxxxx.execute-api.ap-northeast-1.amazonaws.com/production
[done]雑にリクエスト投げるらむだ
ついでに色々試す ip、スペック調査など
[done]globalip -> 3時間くらいでかわる
[done]スペック、ローカルIP
js力
同期的処理の書き方など
コールバック
bot
[done]任意の発言用
画像系とか試してみる？
アイドルとか？

lambda＆api gatewayの方

bot-faker（lineからのリクエストっぽいのを投げるやつ）

'use strict';

var Faker = {};
Faker.createParam = function(to, text) {
    var dummy_req = {
        "result": [
            {
                "toChannel": 1461690851,
                "to": [

                ],
                "id": "WB1520-3472426954",
                "fromChannel": 1341301815,
                "from": "",
                "eventType": "138311609000106303",
                "createdTime": 1464422717466,
                "content": {
                    "seq": null,
                    "contentType": 1,
                    "deliveredTime": 0,
                    "toType": 1,
                    "createdTime": 1464422717448,
                    "from": "u6f27bae0d2XXXXXXXXXXXXXXXXXXXXXX",
                    "location": null,
                    "id": "4379663030496",
                    "to": [
                        "u06b53eXXXXXXXXXXXXXXXXXXXXXXXXXX"
                    ],
                    "text": "",
                    "contentMetadata": {
                        "SKIP_BADGE_COUNT": "true",
                        "AT_RECV_MODE": "2"
                    }
                }
            }
        ]
    };

    dummy_req.result[0].content.text = text;
    dummy_req.result[0].content.from = to;
    return dummy_req;
};


exports.handler = function(event, context) {

    var request = require('request');

    var endPoint = 'https://xxxxxxx.com/callback.php';

    console.log(JSON.stringify(event));

    var dummy_req = Faker.createParam(event.to, event.text);

    request({
        url: endPoint,
        method: 'POST',
        headers: {
            'User-Agent': 'bot-faker'
        },
        body: JSON.stringify(dummy_req)
    }, function (error, response, body) {
        if (error) console.log(error);
        console.log(body);
        context.succeed(true);
    });
};

↑を叩くためのapi gatewayを作成 api gatewayを経由してパラメータを渡す

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"to": "u6f27bae0d2XXXXXXXXXXXXXXXXXXXXXX", "text":"あああ"} https://xxxxxxxx.execute-api.ap-northeast-1.amazonaws.com/production

coop-sender/index.js

'use strict';

exports.handler = function(event, context) {

    var request = require('request');

    // api gateway endpoint
    var endPoint = 'https://xxxxxxxx.execute-api.ap-northeast-1.amazonaws.com/production';

    console.log(JSON.stringify(event));

    var params =[
        {
            "to": "u6f27bae0d2XXXXXXXXXXXXXXXXXXXXXX",  //me
            "text": "say 今週のコープさんをお知らせします"
        },
        {
            "to": "u6f27bae0d2XXXXXXXXXXXXXXXXXXXXXX",
            "text": "こーぷ"
        },
        {
            "to": "u8f0351XXXXXXXXXXXXXXXXXXXXXXXXXX",  //w
            "text": "say 今週のコープさんをお知らせします"
        },
        {
            "to": "u8f0351XXXXXXXXXXXXXXXXXXXXXXXXXX",
            "text": "こーぷ"
        }
    ];

    params.forEach(function(param){
        request({
            url: endPoint,
            method: 'POST',
            body: JSON.stringify(param)
        }, function (error, response, body) {
            if (error) console.log(error);
            console.log(body);
            context.succeed(true);
        });
    });
};

これをlambdaのcron実行で月曜日に実行すると通知が届く

lambda色々

どの程度インスタンスが入れ替わるのか、信頼性はどうなのかというところで気になったのでちょっと調べてみた

1分ごとに実行してIPの変化

[eg@yemen logs]$ cat lambda.log |grep ^52 | uniq -c
    170 52.193.143.241
    231 52.196.216.135
    172 52.196.5.217
    225 52.69.206.172
     97 52.193.23.42
[eg@yemen logs]$ cat lambda.log |grep ^52 | wc -l
895

3時間ぐらいで変わってるっぽい
