A weather Line provider is created, and then click "Create a LINE login channel"

In <Channel icon> I choose a basketball that I downloaded on the internet

Choose <Messaging API> in channel type comboBox

In <Channel name>, I named it as "weatherman"

In <Channel description>: It helps you look up today's weather in Taiwan

In <Category>: 生活相關服務

In <Subcategory>: 生活相關服務(其他)

When you finished the "Basic Settings", you'll see the following stuff.

Then I'm gonna set up "Messaging API"

Turn off both "Auto-reply messages" and "Greeting messages" by clicking the "Edit" buttons on their right-hand sides.

 Before you started to develop the backend program, don't forget to copy the values of the

channel secret and channel access token which will be used later

Install ngrok  and write a simple batch file

Then don't forget to modify the webhook settings in your LINE Bot channel

Go to Messaging API >> Webhook Settings  >> Edit

You also have to run your own lineBotTest.py. The program, a flask server, processes all the events delivered by the Line Bot

Here is an example of the dictionary.  The weather LINE Bot responds with a link when the user inputs a new word and it also pushes a count-down number immediately.
