selenium script written in _init_ function not executing
MADDY312 opened this issue · comments
code :
import scrapy
from scrapy.selector import Selector
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from shutil import which
class test_2(scrapy.Spider):
name='test_2'
#allowed_domains=[]
start_urls=[
'https://www.jackjones.in/st-search?q=shoes'
]
def _init_(self):
print("test-1")
chrome_options=Options()
chrome_options.add_argument("--headless")
driver=webdriver.Chrome("C:/chromedriver")
driver.set_window(1920,1080)
driver.get("https://www.jackjones.in/st-search?q=shoes")
tab=driver.find_elements_by_class_name("st-single-product")
tab[4].click()
self.html=driver.page_source
print("test-2")
driver.close()
def parse(self, response):
print("test-3")
resp=Selector(text=self.html)
yield{
'title':resp.xpath("//h1/text()").get()
}
It appears that compiler does not execute the init function before going to parse function, because neither of the print statements are getting executed but the print statement in parse function is present in the output
How to fix this?
Output:

Hey bud, I know this is pretty old in the ways of development but I thought I'd answer your question.
To start things off, you have an issue with your init method using only a single underscore (init) instead of two (init).
Next, you're not utilizing Scrapy-Selenium here. You're directly calling Selenium manually without the help of this package. This package let's you setup and use Selenium through a DownloaderMiddleware , which is where we want this code to be, not directly in our Spider class.
Third, I'm fairly certain the maintainer of this project either isn't around or has dropped the project. I've forked it to bring it up to date and essentially become the new maintainer, as I found a use for this package myself.
p.s. Owner, if you're reading this, please let us know if this project is still being maintained or if you've moved on :)
