TolkienQuotesBot - J.R.R. Tolkien quotes bot (send a random quote in response to your message)
Recently I decided to write a simple bot to get some experience and the subsequent implementation of more complex projects. The choice fell on the bot of quotes for specific authors / books / genres / tags.
To implement this idea, it was necessary to perform two basic steps:
- Get a large amount of authors, books, quotes, tags data and structure them correctly in the form of tables in the database
- Implement directly the server part of the bot, which would process all requests to the bot
I parsed over 5,000,000 web pages and received over 900,000 quotes from one well-known internet resource.
For these purposes, I wrote a small Java application that processes the web page and records the necessary information in the csv file.
The structure of the csv is as follows
After a couple of days of continuous work of this application, I received a sufficient amount of information that it was possible to record this information in the database. I did not save quotes directly to the database as at that time I hadn’t bought the server yet. =)
To handle csv, I created a simple laravel command class.
For a start, I bought a virtual server, a domain, generated an SSL certificate.
Telegram API provides two mutually exclusive ways of getting bot updates:
- Polling via getUpdates method
I think the first way is more scalable because webhook requests can be loadbalanced between unlimited instances of your bot apps. So I decided to use webhooks.
To implement telegram bots on Laravel I used Telegram Bot API PHP SDK from GitHub.
First, I created a bot that sent a random quote to J.R.R. Tolkien books once an hour and in response to any message from the user.
TolkienQuotesBot - here it is.
But then I decided to transfer the functionality of hourly sending a message to the channel (jrr_tolkien_quotes) in order to reduce the number of requests from my server. I did this simply by adding a bot to the telegram channel and giving it administrator rights, and in the code, I just send messages to this channel every hour.
By analogy, I created the following channels:
Humor - Humor quotes
Success - Success quotes
Inspiration - Inspiration quotes
William Shakespeare - William Shakespeare quotes
George R.R. Martin - George R.R. Martin quotes
J.K. Rowling - J.K. Rowling quotes
Stephen King - Stephen King quotes
J.R.R. Tolkien - J.R.R. Tolkien quotes
In this post, I described what it took me to create simple telegram bots and channels.
