如何在硒中模拟触摸屏？

Question

我正在尝试创建一个机器人，这个机器人必须点击一些不能识别鼠标点击但识别触摸的元素，我在网上搜索了一下，我找到了一种模拟触摸事件的方法。我写了这个

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.touch_actions import TouchActions

user_agent = "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16"
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", user_agent)
driver = webdriver.Firefox(profile)
driver.set_window_size(400, 800)

WebDriverWait(driver, 10).until(lambda d: d.find_element_by_css_selector(".qJfNm").is_displayed())
element = driver.find_element_by_css_selector(".qJfNm")
touchactions = TouchActions(driver)
touchactions.tap(element)

并没有引发错误，但它不起作用，屏幕上没有任何变化。根据文档 https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/interactions/touch/TouchActions.html

该tap方法可模拟mouse clicks并没有touchscreen events，所以我想知道如果有一个模拟的方式touchscreen events上selenium，或这是正确的方式和我错了，这样做。

我也尝试过写作touchactions.tap(element).perform()而不是touchactions.tap(element)

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.touch_actions import TouchActions

user_agent = "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16"
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", user_agent)
driver = webdriver.Firefox(profile)
driver.set_window_size(400, 800)

WebDriverWait(driver, 10).until(lambda d: d.find_element_by_css_selector(".qJfNm").is_displayed())
element = driver.find_element_by_css_selector(".qJfNm")
touchactions = TouchActions(driver)
touchactions.tap(element).perform()

但它引发了这个错误

Traceback (most recent call last):

    touchactions.tap(element).perform()

selenium.common.exceptions.WebDriverException: Message: POST /session/71d75201-9012-46a1-9c6e-1c720dd332ce/touch/click did not match a known command

不明白为什么。

我正在使用gekodriver，python 3并且windows 10

有趣的问题！在这种情况下，也许 tap 还不够，我们需要在 chrome 选项旁边使用 double_tab :)

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

mobile_emulation = { "deviceName": "Nexus 6" }

chrome_options = Options()
chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)

driver = webdriver.Chrome(chrome_options = chrome_options)
    WebDriverWait(driver, 10).until(lambda d: d.find_element_by_css_selector(".qJfNm").is_displayed())
    element = driver.find_element_by_css_selector(".qJfNm")
    touchactions = TouchActions(driver)
    touchactions.double_tab(element)
