Question

我必须打印从产品信息页面链接到的所有html页面： http://prod.adv-bio.com/ProductDetail.aspx?ProdNo=1197

我已经设置了一个测试脚本，看看我是否可以只对其中一个html文件执行此操作。我使用PyChromeDevTools和Selenium，希望我可以在DevTools中使用printToPDF函数，同时使用Selenium点击我需要点击的链接。

这是我到目前为止的代码：

import requests
import time
import re
import websocket
import PyChromeDevTools
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options


chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--remote-debugging-port=9222')
chrome_options.add_argument('--window-size=1200x600')
chrome_options.add_argument('--disable-gpu')




driver = webdriver.Chrome('C:\\Users\\me\\AppData\\Local\\Programs\\Python\\Python36-    32\\selenium\\webdriver\\chromedriver_win32\\chromedriver.exe',         chrome_options = chrome_options)
driver.get("http://prod.adv-bio.com/ProductDetail.aspx?ProdNo=1197")

browser = PyChromeDevTools.ChromeInterface()
browser.Network.enable()
browser.Page.enable()
driver.implicitly_wait(20)                                                                 



driver.get("http://prod.adv-bio.com/ProductDetail.aspx?ProdNo=1197")
time.sleep(3)
url = driver.find_element_by_partial_link_text("Continuing")
time.sleep(3)
ActionChains(driver).click(url).perform()
time.sleep(3)


Page.printToPDF()

time.sleep(5)

我收到此错误

我已经更新了chromedriver到2.31并且有60版铬，我应该使用金丝雀吗？我对此表示感谢。

from selenium.webdriver.common.desired_capabilities import 
DesiredCapabilities    

chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_argument("headless")
chromeOptions.add_argument("window-size=1366,768")

capabilities = DesiredCapabilities.CHROME.copy()
capabilities["browserName"] = "chrome"

driver = webdriver.Chrome(chrome_options=chromeOptions,
desired_capabilities=capabilities)

在这里工作!! （Chrome 60 + Chromedriver 2.31）希望这会有所帮助!!

无头Chrome导航到页面，单击链接页面，然后printToPDF
