CN AirData Scraper Scala

Scrap China air quality data in Scala

My first Scala Script on Github!

• It goes to http://pm25.in/ and scapes all the air quality data for each city, and save it to a file called data.txt.
• Since the website updates the data on a hourly basis, running this script once means taking a snapshot.
• So if you need date more than a 'snapshot', you will need to run this script every 60 min.

TODO:

• Use timestamp in the output file name, so instead of data.txt, it will be like data_20200626_133029.txt.
• Add the time showed on the website to the output file as a column.
• Add the city name to the output file for each monitoring site.
• The table header is stored in the output file many many times. I need to change the code so each output file only have one row of table header.
