tech:linebot [2019/04/09 22:20] – [建立開發環境] jonathan_tsaitech:linebot [2019/04/10 09:23] (目前版本) – [建立一個 LINE BOT] jonathan_tsai
行 1: 行 1:
 +====== 測試建構 LINE BOT (Developer Trial 方案) ======
 +
 +  * 環境 : CentOS Linux release 7.6.1810 (Core)
 +  * 語言 : PHP 7.2
 +  * Web : Nginx 1.12.2
 +  * DB : MariaDB 5.5.60
 +
 +===== 申請Developer Trial帳號 =====
 +  * 參考 - http://at-blog.line.me/tw/create_developer_trial
 +  - https://developers.line.biz/en/
 +  - 使用自己的 LINE 帳號登入
 +  - Create new provider
 +  - Create new channel -> Messaging API -> Plan : Developer Trial
 +
 +===== 建立開發環境 =====
 +  * 安裝 php 與 httpd 相關套件<code sh>
 +yum install epel-release
 +rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
 +yum install composer mariadb mariadb-server nginx unzip php72w php72w-cli php72w-common php72w-curl php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-process php72w-snmp php72w-xml php72w-zip php72w-opcache
 +</code>
 +  * 設定 Web server - nginx <code sh>
 +vi /etc/php-fpm.d/www.conf
 +</code><file>
 +:
 +;user = apache
 +user = nginx
 +; RPM: Keep a group allowed to write in log dir.
 +group = apache
 +
 +; The address on which to accept FastCGI requests.
 +; Valid syntaxes are:
 +;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
 +;                            a specific port;
 +;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
 +;                            a specific port;
 +;   'port'                 - to listen on a TCP socket to all addresses
 +;                            (IPv6 and IPv4-mapped) on a specific port;
 +;   '/path/to/unix/socket' - to listen on a unix socket.
 +; Note: This value is mandatory.
 +;listen = 127.0.0.1:9000
 +listen = /var/run/php-fpm/php7.2-fpm.sock
 +
 +; Set listen(2) backlog.
 +; Default Value: 511 (-1 on FreeBSD and OpenBSD)
 +;listen.backlog = 511
 +
 +; Set permissions for unix socket, if one is used. In Linux, read/write
 +; permissions must be set in order to allow connections from a web server. Many
 +; BSD-derived systems allow connections regardless of permissions.
 +; Default Values: user and group are set as the running user
 +;                 mode is set to 0660
 +;listen.owner = nobody
 +;listen.group = nobody
 +;listen.mode = 0660
 +listen.owner = nginx
 +listen.group = nginx
 +listen.mode = 0660
 +
 +; When POSIX Access Control Lists are supported you can set them using
 +; these options, value is a comma separated list of user/group names.

 +===== 驗證 Webhook 是否可以正確連上 =====
 +
 +  * 假設 Channel 為 iChiaYi-Bot
 +  * Use webhooks -> Enable  
 +  * 假設 Webhook URL 為 https://www.ichiayi.com/linebot/Webhook.php -> 按下 Verify 後要能夠看到 Success
 +  * 如果想要讓 Bot 可以被邀請加入某群組中 Allow bot to join group chats -> Enable
 +
 +===== 安裝 line-bot-sdk-php =====
 +  * 透過 composer 安裝 <code sh>
 +cd /usr/share/nginx/
 +composer require linecorp/line-bot-sdk
 +cd vendor/linecorp/line-bot-sdk/
 +composer install
 +</code>
 +
 +===== 寫一個 LINE BOT 程式 =====
 +  * 至 https://developers.line.biz/console/ 選上面建立的 Provider -> channel Exp. iChiayi-Bot (Messaging API)
 +    * Channel settings :
 +        * QR Code : 可以讓手機 LINE 直接掃描加 BOT 當好友，也可以將 BOT 邀請到 LINE 群組內
 +        * Channel secret : 提供後續開發時重要的 KEY, 大概長的像這樣<file>629345c1d259db2e59c308e05b371f5x</file>
 +        * Channel access token(long-lived) : 提供後續開發時重要的 KEY, 大概長的像這樣<file>

 +  * 開始寫一個簡單的 BOT 程式 Webhook.php<code sh>
 +vi /usr/share/nginx/html/Webhook.php
 +</code><code php>
 +<?php
 +require '/usr/share/nginx/vendor/linecorp/line-bot-sdk/vendor/autoload.php';
 +$httpClient = new \LINE\LINEBot\HTTPClient\CurlHTTPClient('<channel access token>');
 +$bot = new \LINE\LINEBot($httpClient, ['channelSecret' => '<channel secret>']);
