[FIXED] Python Scrapy 503 Service Unavailable

Issue

i keep getting the "503 Service Unavailable" when i try and scrape the checkatrade website. I have tried putting concurrent requests to 1, download_delay to 10, having a user_agent but it just gets blocked at the first attempt of the start_url

the code below shows my attempt, i have also tried selenium (i have left the selenium code in comments below in the code - and even then it does not register the start_url):

import scrapy
from urllib.parse import urljoin

#from scrapy.http import TextResponse
#from selenium import webdriver

from checkatrade.items import CheckatradeItem

class checkatradeSpider(scrapy.Spider):
    name = "checkatrade"
    allowed_domains = ["checkatrade.com"]

    start_urls = ["https://www.checkatrade.com/Directory/A"]    
    

#    def __init__(self):
#        try:
#            self.driver = webdriver.Chrome("C:/Users/andrew/Downloads/chromedriver_win32/chromedriver.exe")
#        except:
#            self.driver = webdriver.Chrome("C:/Users/andre/Downloads/chromedriver_win32/chromedriver.exe")

    def parse(self, response):
#        self.driver.get(response.url)
        
#        response1 = TextResponse(url=response.url, body=self.driver.page_source, encoding='utf-8')
        
#        for sel in response1.xpath('//*[@class="directory"]/tbody/tr'):
        for sel in response.xpath('//*[@class="directory"]/tbody/tr'):            
           member = sel.xpath('normalize-space(.//td/a/text())').extract()
           memberurl = sel.xpath('normalize-space(.//td/a/@href)').extract()
           basedin = sel.xpath('normalize-space(.//td[2]/text())').extract()
           memberfor = sel.xpath('normalize-space(.//td[3]/text())').extract()
           reports = sel.xpath('normalize-space(.//td[4]/text())').extract()
           rating = sel.xpath('normalize-space(.//td[5]/text())').extract()
           item = CheckatradeItem()
           item['member'] = member
           item['memberurl'] = memberurl
           item['basedin'] = basedin
           item['memberfor'] = memberfor
           item['reports'] = reports
           item['rating'] = rating
           yield item


#        self.driver.close()
#        try:
#            self.driver = webdriver.Chrome("C:/Users/andrew/Downloads/chromedriver_win32/chromedriver.exe")
#        except:
#            self.driver = webdriver.Chrome("C:/Users/andre/Downloads/chromedriver_win32/chromedriver.exe")
    

Solution

But it's working without any issue.

import time

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

#options to add as arguments
from selenium.webdriver.chrome.options import Options
option = webdriver.ChromeOptions()
option.add_argument("start-maximized")

#chrome to stay open
option.add_experimental_option("detach", True)

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()),options=option)
driver.get('https://www.checkatrade.com/Directory/A')
time.sleep(2)

for sel in driver.find_elements(By.XPATH,'//*[@class="directory"]/tbody/tr'):            
    member = sel.find_element(By.XPATH,'.//td/a').text
    print(member)
