Parsing with Ruby, Nokogiri & Mechanize java cookies links in a webpage - ruby

Question

everyone.
I need to parse a webpage which has java cookies set for every link. I can parse the normal search and every product is shown and imported to a mysql database.
I was able to scrape from a search result every product with its elements with this code:
This is what I have:
require 'rubygems'
require 'logger'
require 'mechanize'
require 'mysql2'
agent = WWW::Mechanize.new{|a| a.log = Logger.new(STDERR) }
#agent.set_proxy('a-proxy', '8080')
agent.read_timeout = 60
def add_cookie(agent, uri, cookie)
uri = URI.parse(uri)
Mechanize::Cookie.parse(uri, cookie) do |cookie|
agent.cookie_jar.add(uri, cookie)
end
end
# get main page
page = agent.get "http://www.site.com.mx"
# get login form
form = page.forms.first
form.correo_ingresar = "user"
form.password = "password"
# submit login form
page = agent.submit form
# parse cookies
myarray = page.body.scan(/SetCookie\(\"(.+)\", \"(.+)\"\)/)
# set session cookies
myarray.each do |item|
add_cookie(agent, 'http://www.site.com.mx', "#{item[0]}=#{item[1]}; path=/; domain=www.site.com.mx")
end
# show 1000 search results per page
add_cookie(agent, 'http://www.site.com.mx', "tampag=1000; path=/; domain=www.site.com.mx")
# order results
add_cookie(agent, 'http://www.site.com.mx', "orden_articulos=existencias asc; path=/; domain=www.site.com.mx")
# section results
add_cookie (agent, 'http://www.site.com.mx', "codigoseccion_buscar=14; path=/; domain=www.site.com.mx")
# get main page
page = agent.get "http://www.site.com.mx/tienda/index.php"
search_form = page.forms.first
search_result = agent.submit search_form
doc = Nokogiri::HTML(search_result.body)
rows = doc.css("table.articulos tr")
i = 0
details = rows.collect do |row|
detail = {}
[
[:sku, 'td[3]/text()'],
[:desc, 'td[4]/text()'],
[:qty, 'td[5]/text()'],
[:qty2, 'td[5]/p/b/text()'],
[:price, 'td[6]/text()']
].collect do |name, xpath|
detail[name] = row.at_xpath(xpath).to_s.strip
end
i = i + 1
detail
end
# walk through paginator links
links = doc.css("a.paginar").map {|l| "http://www.site.com.mx#{l['href']}"}.uniq!
links.each do |l|
page = agent.get l
doc = Nokogiri::HTML(page.body)
rows = doc.css("table.articulos tr")
rows.each do |row|
detail = {}
[
[:sku, 'td[3]/text()'],
[:desc, 'td[4]/text()'],
[:qty, 'td[5]/text()'],
[:qty2, 'td[5]/p/b/text()'],
[:price, 'td[6]/text()']
].collect do |name, xpath|
detail[name] = row.at_xpath(xpath).to_s.strip
end
details << detail
end
end
# update db
client = Mysql2::Client.new(:host => "localhost", :username => "myusername", :password => "mypassword", :database => "mydatabase")
details.each do |d|
if d[:sku] != ""
price = d[:price].split
if price[1] == "D"
currency = 144
else
currency = 168
end
cost = price[0].gsub(",", "").to_f
if d[:qty] == ""
qty = d[:qty2]
else
qty = d[:qty]
end
results = client.query("SELECT * FROM jos_vm_product WHERE product_sku = '#{d[:sku]}' LIMIT 1;")
if results.count == 1
product = results.first
client.query("UPDATE jos_vm_product SET product_sku = '#{d[:sku]}', product_name = '#{d[:desc]}', product_desc = '#{d[:desc]}', product_in_stock = '#{qty}' WHERE product_id =
#{product['product_id']};")
client.query("UPDATE jos_vm_product_price SET product_price = '#{cost}', product_currency = '#{currency}' WHERE product_id = '#{product['product_id']}';")
else
client.query("INSERT INTO jos_vm_product(product_sku, product_name, product_desc, product_in_stock) VALUES('#{d[:sku]}', '#{d[:desc]}', '#{d[:desc]}', '#{qty}');")
last_id = client.last_id
client.query("INSERT INTO jos_vm_product_price(product_id, product_price, product_currency) VALUES('#{last_id}', '#{cost}', #{currency});")
end
end
end
Now I dont want to search I want to parse from the Categories list:
link to main page:http://www.site.com.mx/tienda/articulos.php?opcion=lineas&seccion_mostrar=11
this shows a table like this (everything contains links)
The top name: ACCESORIOS is a link to the category ACCESORIOS, and the bold names listed bellow is the subcategories, and the ones bellow the bold names are brands. If I click on ACCESORIOS it will show every brand and every subcategory mixed up, and so on.

so the question is what do I add to my code to be able to access every link? if it uses java cookies.
Cookies used:
Name , Value Ranges
codigoseccion_buscar, 11-30
codigomarca_buscar, 100-736
codigolinea_buscar, 15-1385

Answer 1

I managed to scrape one of those links contents by adding cookies to my Ruby code:
# set cookies
add_cookie(agent, 'http://www.site.com.mx', "codigoseccion_buscar=11; path=/; domain=www.site.com.mx")
add_cookie(agent, 'http://www.site.com.mx', "codigolinea_buscar=; path=/; domain=www.site.com.mx")
add_cookie(agent, 'http://www.site.com.mx', "codigomarca_buscar=; path=/; domain=www.site.com.mx")
add_cookie(agent, 'http://www.site.com.mx', "textobuscar=; path=/; domain=www.site.com.mx")
weird thing was that if I only added one of those cookies it would not work. so I had to add all , even tho they dont have any values, because every link has a cookie, so that way it would delete or clear saved cookie.
now I need to scrape those cookies use it as variable and do a loop or something, anybody can help me?
