Selenium 循环脚本使用过多内存，最终导致 Chrome 崩溃

Question

I have a very large list of URLs I'm trying to scrape , I'm iterating over every URL using a for loop.

Eventually, in x element of the list, my Chrome window will crash ('Aw Snap!' error appears on the browser window). I don't have any idea to fix this issue.

I can't share my code, but is something like this:

very_large_url_list = [url1, url2, url3, url4...]

for x in very_large_url_list:
    driver.get(x)
    doStuff()

If I try to close the driver on every iteration, like this:

for x in very_large_url_list:
    driver.get(x)
    doStuff()
    driver.close()

I'd get an error stating that the session ID is invalid. If I don't close it, then a memory leakage will happen eventually and I wont be able to finish the iteration over the list. What can I do to fix this issue?

Please let me know if I haven't been clear enough so I can edit the question!

Answer 1

If you try to close the driver on every iteration, shouldn't you be doing this?

for x in very_large_url_list:
    driver = webdriver.Chrome()
    driver.get(x)
    doStuff()
    driver.close()

Answer 2

Do you know that we can open a URL without using any browser as well? It is frequently asked interview question as well. Let's learn it.

Let's perform some steps first:

1. Open a browser.
2. Press F12.
3. Switch to Console tab.
4. Type window.location='https://www.redbus.in' and hit Enter key.

You will notice that redbus website is loaded.

This is the way of loading URL without using any methods like get() or navigate() . Above statement is called as JavaScript command. We will see JavaScript concepts later.
