執行專案

初始化

• Step1. 建立環境變數檔案

cp .env.example .env

• Step2. 修改.env參數內容，包含MongoDB連線參數及Linebot相關密鑰設定

DB_CONNECTION = mongodb
DB_HOST = mongo
DB_PORT = 27017
DB_USERNAME = admin
DB_PASS = admin

LINE_CHANNEL_ID =
LINE_CHANNEL_SECRET =
LINE_CHANNEL_ACCESS =

• Step3. 登入Line Developers

• Step4. 點擊Messaging API進行官方帳號及Webhook設定 將URL設定到Webhook

  PS. local端測試使用Ngrok

  https://{some domain}/messages/receive

啟動專案

docker-compose up -d --build

使用範例

• 連接測試

curl https://{some domain}

• 取得官方帳號訊息列表

[GET] https://{some domain}/user/{Line official account user id}/messages

• 利用官方帳號推送訊息

[POST] https://{some domain}/messages/push

# Content-Type: application/json
# Body parameters
{
    "UserID": "Line official account user id",
    "Content": "some message you want to push"
}
