[RUBY] [Abuse strictly prohibited] Get the number of views of your Qiita article

I tried to work on the graph system two times before, but since the data itself was a little subtle, I would like to graph the transition of the number of views of the article posted on Qiita as a revenge!

Today's Goals / Deliverables

Today I write a code to get the number of views of the article I posted on Qiita

Code and documentation

1. Prepare the scraping base code

https://qiita.com/itaya/items/262eec85e36763497664

I wrote about scraping Qiita once in the article above, so basically I will use this.

crawler.rb

require 'nokogiri'
require 'mechanize'
require 'selenium-webdriver'

def selemium_init
  ua = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36'
  # caps = Selenium::WebDriver::Remote::Capabilities.chrome('chromeOptions' => { args: ["--user-agent=#{ua}", 'window-size=1280x800', '--incognito'] }) #Secret mode
  caps = Selenium::WebDriver::Remote::Capabilities.chrome('chromeOptions' => {args: ["--headless","--no-sandbox", "--disable-setuid-sandbox", "--disable-gpu", "--user-agent=#{ua}", 'window-size=1280x800']})
  
  client = Selenium::WebDriver::Remote::Http::Default.new
  driver = Selenium::WebDriver.for :chrome, desired_capabilities: caps  
end

driver = selemium_init
driver.navigate.to 'https://qiita.com/login'
driver.execute_script("document.getElementsByName('identity')[0].value = 'mail address'")
driver.execute_script("document.getElementsByName('password')[0].value = 'password'")
driver.execute_script("document.getElementsByName('commit')[0].click()")
sleep 1

Here is the code to log in.

2. Get information about your page

From here, this time I will get a list of my pages and jump to that page to get a collection of views

crawler.rb

driver.navigate.to 'https://qiita.com/itaya'
sleep 1
doc = Nokogiri::HTML.parse(driver.page_source, nil, 'utf-8')
doc.css('.AllArticleList__Item-mhtjc8-2').each do |div|
  driver.navigate.to "https://qiita.com" + div.css('.AllArticleList__ItemBodyTitle-mhtjc8-6')[0]['href']
  sleep 1
  article_doc = Nokogiri::HTML.parse(driver.page_source, nil, 'utf-8')
  p article_doc.css('.it-Header_pv')[0].text.split(" ")[0]
end

I feel like this.

3. Now run! !!

When you run this

"99"
"56"
"218"
"212"
"120"
"107"
"288"
"112"
"213"
"93"
"111"
"128"
"131"
"149"
"383"
"801"
"4629"
"510"
"1086"

You can get the number of views of the article displayed on the first page like this. However, I can't get the number of views of the articles on the second and subsequent pages with this alone, so I'd like to make that part tomorrow ....

** * Please note that too many requests will overwhelm the server !!! **

You can use Qiita's API normally ... https://qiita.com/api/v2/docs#%E6%8A%95%E7%A8%BF
