未知错误:无法等待扩展程序后台页面加载:chrome-extension错误，使用Selenium将扩展程序加载到Chrome Headless [英] unknown error: failed to wait for extension background page to load: chrome-extension error loading an extension to Chrome Headless using Selenium

问题描述

我尝试以无头模式通过硒运行chromedriver.

I try to run chromedriver via selenium in headless mode.

重要如果我消除以下代码行(但不是无头的话)，则代码可以正常运行:

IMPORTANT The code runs perfectly fine if I eliminate the following code lines (but is not headless):

chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')

这是我尝试实现无头参数时遇到的错误:

This is the error I get when I try to implement the headless argument:

Traceback (most recent call last):
  File "camel.py", line 83, in <module>
    executable_path=executable_path)

from unknown error: page could not be found: chrome-extension://jkompbllimaoekaogchhkmkdogpkhojg/_generated_background_page.html

这是第81、82和83行

This are the lines 81, 82 and 83

chrome_options.add_extension(extension_path)
driver = webdriver.Chrome(options=chrome_options,
                          executable_path=executable_path)

这是代码(crhomedriver执行部分):

This is the code (the crhomedriver execution parts):

from selenium import webdriver
from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.expected_conditions import presence_of_element_located

import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))

chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
log_path = os.path.join(BASE_DIR, 'cronJobChromeDriver.log')

executable_path = os.path.join(BASE_DIR, 'chromedriver_linux64/chromedriver')
extension_path = os.path.join(
    BASE_DIR, 'chromedriver_linux64/extension_2_8_9_0.crx')
print('executable_path', executable_path)

推荐答案

最底行是否， google-chrome-headless 不支持扩展.

The bottom line is, No, google-chrome-headless doesn't supports extensions.

在他的评论之一中，提到了 [e-mail] :

In the one of his comment, [e-mail] mentioned:

我知道很多人都想无头使用扩展，但是不幸的是，这是一个大项目，我们尚无计划/.问题在于Headless Chromium是一个内容嵌入程序，这意味着它无法访问其他内容嵌入程序(例如chrome)中的任何内容，不幸的是扩展是chrome功能.

I realize a lot of folks would like to use extensions with headless but unfortunately that's a large project which we have /no plans to do/. The problem is Headless Chromium is a content embedder which means it doesn't have access to anything from other content embedders such as chrome and unfortunately extensions are a chrome feature.

在另一个评论中，他进一步补充说，如果您通过硒="https://stackoverflow.com/questions/59420493/how-to-use-chrome-devtools-protocol-in-selenium-using-python-for-capturing-htt/59424003#59424003"> DevTools 您可以建立代理.接下来，您可以通过 Network.setRequestInterception 和 Network.continueInterceptedRequest .

In another comment he further added, if you're using Selenium through DevTools you can build a proxy. Next you can filter URLs and modify headers via Network.setRequestInterception and Network.continueInterceptedRequest.
