沒有程式的生活圈是什麼樣的？
簡單說就只是「沒有程式自動化」，也就是沒有機器人自動回答，可以一對一客服也可以發訊息給全部好友
換句話說，如果想要讓客戶自行輸入關鍵字即可得到資訊就需要使用 API，需要切換到何種方案就需要看進一步的需求

名詞釋疑
生活圈 LINE@ 從 https://at.line.me/tw/ 建立的叫做生活圈，後台是 https://admin-official.line.me
生活圈 LINE@ 建立的稱作「帳號」，LINE Developers 建立的叫做 channel
使用生活圈必須另外在手機上下載使用另一個 LINE@ 的 APP 來管理 LINE 生活圈，生活圈的管理是無法從網頁後台或是 LINE 去操作的

接收 LINE 的訊息
收到的訊息是 JSON 格式，大概長這樣
|
|
{"events":[{"type":"message","replyToken":"abf341d141ea4d4c94cd510871163f84","source":{"userId":"Uc5629999999999999999999c88ed8","type":"user"},"timestamp":1535249611645,"message":{"type":"text","id":"8475560626630","text":"..."}}]} |
比較容易看的格式

發送 - 圖檔
|

'to' => array('user1', 'user2', ...), 'messages' => [ [ 'type' => 'image', 'originalContentUrl' => 'https://hoyo.idv.tw/line.jpg', 'previewImageUrl' => 'https://hoyo.idv.tw/line.jpg' ] ] |

發送 - 視頻
官方文件說有影片以及預覽圖大小限制，實際上因為檔案放在自己主機上，所以並無限制
|
|
'to' => array('user1', 'user2', ...), 'messages' => [ [ 'type' => 'video', 'originalContentUrl' => 'https://hoyo.idv.tw/line.mp4', 'previewImageUrl' => 'https://hoyo.idv.tw/line.jpg' ] ] |
--
發送 - 音頻
|
|
'to' => array('user1', 'user2', ...), 'messages' => [ [ 'type' => 'audio', 'originalContentUrl' => 'https://hoyo.idv.tw/line.mp4', 'duration' => 10000 ] ] |
- duration 單位為千分之一毫秒，只和顯示播放倒數有關，音頻有多長還是播多長
