使用 Selenium、PhantomJS 和 BS4 进行刮擦

Question

I'm currently using Windows 10 and Python 3.7 and I've been reading about how to scrape without opening up 1 Firefox browser window for each URLs that's being scraped in the urls list. The code below is throwing an error back and I'm sure it's got something to do with how PhantomJS is being implemented, I just don't know what specifically.

I've read that PhantomJS was a solution when used with Selenium. I installed PJS, set up the Path on my computer and it appears to be running however I'm not completely sure how to implement it in the code itself.

The driver = webdriver.PhantomJS(executable_path=r"C:\phantomjs") line is the line attempting to run the PJS. The code worked just fine before using driver = webdriver.Firefox() .

Answer 1

Make sure to download the correct PhantomJs distribution for your operational system here .

For Windows, the following line of code should work just fine:

driver = webdriver.PhantomJS("C://phantomjs.exe")
driver.get(url)
