如何使用带有Chrome设备工具栏的Selenium和Python在Instagram直接消息中向上滚动

Question

我正在尝试自动执行Instagram Direct上的滚动操作，以便能够开始Instagram聊天。另外，我认为无法使用xpath选择滚动条，因此可能有必要使用带有“ home”键或“ page up”的自动按键循环。但是说实话，我真的不知道该怎么做。附言：如果按住“ home”键，您只能在滚动停止之前向上滚动几页，因此您需要在几秒钟后释放该键以继续向上滚动。因此，也许这不是执行我要寻找的最佳方法。希望有人能帮助我，非常感谢！

源代码：

    from selenium import webdriver
    from time import sleep
    from secrets import username, pw


    from selenium.webdriver.chrome.options import Options

    mobile_emulation = {

        "deviceMetrics": { "width": 360, "height": 640, "pixelRatio": 3.0 },

        "userAgent": "Mozilla/5.0 (Linux; Android 4.2.1; en-us; Nexus 5 Build/JOP40D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19" }

    chrome_options = Options()

    chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)




    class MsgBot:
def __init__(self):
    self.driver = webdriver.Chrome(chrome_options = chrome_options)

    self.driver.get("https://instagram.com")
    sleep(2)
    self.driver.find_element_by_xpath('//*[@id="react-root"]/section/main/article/div/div/div/div[2]/button').click()
    sleep(5)
    login_input = self.driver.find_element_by_xpath('//*[@id="react-root"]/section/main/article/div/div/div/form/div[4]/div/label/input')
    login_input.send_keys(username)
    pw_input = self.driver.find_element_by_xpath('//*[@id="react-root"]/section/main/article/div/div/div/form/div[5]/div/label/input')
    pw_input.send_keys(pw)
    login_btn = self.driver.find_element_by_xpath('//*[@id="react-root"]/section/main/article/div/div/div/form/div[7]/button').click()
    sleep(4)
    self.driver.find_element_by_xpath('//*[@id="react-root"]/section/main/div/button').click()
    sleep(4)
    self.driver.find_element_by_xpath('/html/body/div[4]/div/div/div[3]/button[2]').click()
    sleep(2)
    self.driver.find_element_by_xpath('//*[@id="react-root"]/section/nav[1]/div/div/header/div/div[2]/a/div').click()
    sleep(4)
    self.driver.find_element_by_xpath('/html/body/div[4]/div/div/div[3]/button[2]').click()
    sleep(4)
    self.driver.find_element_by_xpath('//*[@id="react-root"]/section/div[2]/div/div/div[2]/div/div[2]/a').click()
    sleep(3)
    #scroll should begin

要滚动到该元素，可以使用：

from selenium.webdriver.common.action_chains import ActionChains

actions = ActionChains(driver)
element = driver.find_element_by_id("id")
actions.move_to_element(element).perform()

或

driver.execute_script("arguments[0].scrollIntoView();", element)

使用JavaScript代码滚动到元素
