[PYTHON] It seems that the Messaging API has been newly released from LINE, so I made a BOT that just analyzes morphological elements as usual.

Introduction

I made the exact same thing with my Trial account before, but I got a threatening email saying "I'm going to delete all my accounts !!", so I moved.

I wish I could get on the SDK's Wiki page ...

Settings on the LINE management screen side

Sure enough, you have to use HTTPS, so let's do our best!

Do your best to reach the LINE @ management screen and use ** "Account Settings" **> ** "Bot Settings" ** to make the settings you want!

Actual response

It's very hard to see ...

Finally

If there is anything, I want you to submit a pull request etc.! Also, please give me a LINE Wiki page.

I was impatient at first because there is no request.headers ['X-LINE-Signature'] in the old API and this new API. By the way, in the old API, it corresponds to request.headers ['X-Line-Channelsignature'].
