I am trying to use SCRAPY to scrape this website's search reqults for any search query - http://www.bewakoof.com .
The website uses AJAX (in the form of XHR) to display the search results. I managed to track the XHR, and you notice it in my code as below (inside the for loop, wherein i am storing the URL to temp, and incrementing 'i' in the loop)-:
from twisted.internet import reactor
from scrapy.crawler import CrawlerProcess, CrawlerRunner
import scrapy
from scrapy.utils.log import configure_logging
from scrapy.utils.project import get_project_settings
from scrapy.settings import Settings
import datetime
from multiprocessing import Process, Queue
import os
from scrapy.http import Request
from scrapy import signals
from scrapy.xlib.pydispatch import dispatcher
from scrapy.signalmanager import SignalManager
import re
query='shirt'
query1=query.replace(" ", "+")
class DmozItem(scrapy.Item):
productname = scrapy.Field()
product_link = scrapy.Field()
current_price = scrapy.Field()
mrp = scrapy.Field()
offer = scrapy.Field()
imageurl = scrapy.Field()
outofstock_status = scrapy.Field()
class DmozSpider(scrapy.Spider):
name = "dmoz"
allowed_domains = ["http://www.bewakoof.com"]
def start_requests(self):
task_urls = [
]
i=1
for i in range(1,2):
temp=( "http://www.bewakoof.com/search/searchload/search_text/" + query + "/page_num/" + str(i) )
task_urls.append(temp)
i=i+1
start_urls = (task_urls)
p=len(task_urls)
print 'hi'
return [ Request(url = start_url) for start_url in start_urls ]
print 'hi'
def parse(self, response):
print 'hi'
print response
items = []
for sel in response.xpath('//html/body/div[@class="main-div-of-product-item"]'):
item = DmozItem()
item['productname'] = str(sel.xpath('div[1]/span[@class="lazyImage"]/span[1]/a/img[@id="main_image"]/@title').extract())[17:-6]
item['product_link'] = "http://www.bewakoof.com"+str(sel.xpath('div[1]/span[@class="lazyImage"]/span[1]/a/img[@id="main_image"]/@href').extract())[3:-2]
item['current_price']='Rs. ' + str(sel.xpath('div[1]/div[@class="product_info"]/div[@class="product_price_nomrp"]/span[1]/text()').extract())[3:-2]
item['mrp'] = item['current_price']
item['offer'] = str('No additional offer available')
item['imageurl'] = str(sel.xpath('div[1]/span[@class="lazyImage"]/span[1]/a/img[@id="main_image"]/@data-original').extract())[3:-2]
item['outofstock_status'] = str('In Stock')
items.append(item)
spider1 = DmozSpider()
settings = Settings()
settings.set("PROJECT", "dmoz")
settings.set("DOWNLOAD_DELAY" , 5)
crawler = CrawlerProcess(settings)
crawler.crawl(spider1)
crawler.start()
Now, as I execute this, I get unexpected errors-:

If you correctly see my code, I have also set the DOWNLOAD_DELAY=5, still it gives the same errors as to when I didn't keep it. I also increased DOWNLOAD_DELAY=10, still it gives the same errors. I have read many questions related to this on Stack Overflow, also on GitHub , but none of them seem to help.
I read in one ofthe answers, that TOR with Polipo, can help. But, I am a bit doubtful for using it, because I don't know whether is it legal to use the combination of TOR with Polipo to scrape websites using Scrapy? (I don't want to run into trouble with any legal issues.) That is the reason why I didn't prefer to use it. So, in case if it is legal, please provide the code for my SPECIFIC CASE, using TOR and POLIPO.
Or rather, if that is illegal, Help me resolve it without using them.
Please help me resolve these errors!
EDIT:
This is my updated code-:
