問題描述

Selenium driver.get (url) 等待整個頁面加載.但是一個抓取頁面會嘗試加載一些死掉的 JS 腳本.所以我的 Python 腳本等待它并且不能工作幾分鐘.這個問題可能出現在網站的每個頁面上.

Selenium driver.get (url) wait till full page load. But a scraping page try to load some dead JS script. So my Python script wait for it and doesn't works few minutes. This problem can be on every pages of a site.

from selenium import webdriver

driver = webdriver.Chrome()
driver.get('https://www.cortinadecor.com/productos/17/estores-enrollables-screen/estores-screen-corti-3000')
# It try load: https://www.cetelem.es/eCommerceCalculadora/resources/js/eCalculadoraCetelemCombo.js 
driver.find_element_by_name('ANCHO').send_keys("100")

如何限制等待時間，阻止文件的AJAX加載，或者其他方式?

How to limit the time wait, block AJAX load of a file, or is other way?

我還在 webdriver.Chrome() 中測試我的腳本，但會使用 PhantomJS()，或者可能是 Firefox().因此，如果某些方法使用了瀏覽器設置的更改，那么它必須是通用的.

Also I test my script in webdriver.Chrome(), but will use PhantomJS(), or probably Firefox(). So, if some method uses a change in browser settings, then it must be universal.

當 Selenium 默認加載頁面/url 時，它遵循默認配置，將 pageLoadStrategy 設置為 normal.為了使 Selenium 不等待整個頁面加載，我們可以配置 pageLoadStrategy.pageLoadStrategy 支持以下 3 種不同的值:

When Selenium loads a page/url by default it follows a default configuration with pageLoadStrategy set to normal. To make Selenium not to wait for full page load we can configure the pageLoadStrategy. pageLoadStrategy supports 3 different values as follows:

1. 正常(全頁加載)
2. 渴望(交互式)
3. 無

這是配置pageLoadStrategy的代碼塊:

Here is the code block to configure the pageLoadStrategy :

• 火狐:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities().FIREFOX
caps["pageLoadStrategy"] = "normal"  #  complete
#caps["pageLoadStrategy"] = "eager"  #  interactive
#caps["pageLoadStrategy"] = "none"
driver = webdriver.Firefox(desired_capabilities=caps, executable_path=r'C:path	ogeckodriver.exe')
driver.get("http://google.com")

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities().CHROME
caps["pageLoadStrategy"] = "normal"  #  complete
#caps["pageLoadStrategy"] = "eager"  #  interactive
#caps["pageLoadStrategy"] = "none"
driver = webdriver.Chrome(desired_capabilities=caps, executable_path=r'C:path	ochromedriver.exe')
driver.get("http://google.com")

注意 : pageLoadStrategy 值 normal, eager 和 none 是 WebDriver W3C Editor's Draft 但 pageLoadStrategy 值作為 eager 仍然是一個WIP(Work InChromeDriver 實施中的進展).您可以在 渴望"頁面加載中找到詳細討論Python 中 Chromedriver Selenium 的策略解決方法

Note : pageLoadStrategy values normal, eager and none is a requirement as per WebDriver W3C Editor's Draft but pageLoadStrategy value as eager is still a WIP (Work In Progress) within ChromeDriver implementation. You can find a detailed discussion in "Eager" Page Load Strategy workaround for Chromedriver Selenium in Python
