Python 无法让脚本向右滑动按钮

我已经用python和selenium编写了一个脚本来登录网站。问题是我的脚本有时会成功登录，但大多数情况下它会遇到一个滑块，该滑块用于按下并向右滑动

• 该滑块的图像：

如何让脚本向右滑动该按钮？

我试过：

from selenium import webdriver
from selenium.webdriver import ActionChains
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

def sign_in():
    driver.get("https://login.aliexpress.com/")
    wait.until(EC.frame_to_be_available_and_switch_to_it(wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "#alibaba-login-box")))))
    wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "input#fm-login-id"))).send_keys("someEmail")
    wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "input#fm-login-password"))).send_keys("somePassword")
    wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "button[class$='password-login']"))).click()

    #the following line is for handling the slider but it doesn't do anything

    item = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, ".nc_wrapper .btn_slide")))
    ActionChains(driver).move_to_element(item).perform()

if __name__ == '__main__':
    driver = webdriver.Chrome()
    wait = WebDriverWait(driver,10)
    sign_in()

连接到该滑块的Html元素：

帮助

尝试使用下面的操作是c#代码供参考

//following code will click and hold the slider
string Xpath=""; //set xpath for desired element to be click and hold
Actions clickHold = new Actions(driver);
IWebElement element = driver.FindElement(By.XPath(Xpath));
clickHold.ClickAndHold(element).Perform();

按住滑块后，尝试将其移动到所需的偏移值

int x = 100; 
int y = 100;
Actions moveOffset = new Actions(driver);
moveOffset.MoveByOffset(x,y).Perform(); //set your suitable (x,y) offset value

下面是从左向右滑动操作的示例代码（java）

Actions slider=new Actions(driver);
slider.clickAndHold("xpath of slider");
slider.movebyoffset(x,y).build.perform(); 

---

代替“x”和“y”，您可以根据您的应用程序给出实际偏移值。

我无法在问题中链接的网站上显示滑块，因此我提供了一个使用另一个具有滑块元素的网站的解决方案（我假设该功能类似于aliexpress网站上的功能）

这里的关键部分是执行滑动动作的

行。我们必须确定两个具体因素：

我们将要滑动的元素
容纳此元素的容器
找到这两个元素后，我们使用actions类单击并按住需要滑动的元素，然后沿x轴滑动包含元素的宽度（如使用
slider\u container.size['width']
所示），而不更改y轴

这将解决您的滑动问题，但是您将有另一个问题，您需要确定是否显示了滑块，或者您已登录网站。为此，您需要一个预期条件来检查是否存在2个元素：

滑块
成功登录后希望看到的元素
如果显示登录时希望看到的元素，则无需执行任何操作。如果显示滑块，则需要执行上述逻辑来滑动条

*编辑*

要进一步改进这一点，您可以将滑动代码置于如下所示的预期条件中：

class wait_for_element_while_verifying_slider(object):

    def __init__(self, locator, slider_container_locator, slider_locator):
        self.locator = locator
        self.slider_container_locator = slider_container_locator
        self.slider_locator = slider_locator

    def __call__(self, _driver):
        try:
            return _driver.find_element(*self.locator)
        except (NoSuchElementException, StaleElementReferenceException):
            container = _driver.find_elements(*self.slider_container_locator)
            slider = _driver.find_elements(*self.slider_locator)
            if len(container) > 0 and len(slider) > 0:
                actions = ActionChains(_driver)
                actions.move_to_element(slider[0]).click_and_hold().move_by_offset(container[0].size['width'], 0).release().perform()

        return False

这将搜索您希望在登录时显示的元素。如果您成功登录后希望看到的元素未显示，则它将尝试定位滑块元素，并与它们交互以处理幻灯片验证。请注意，一旦它尝试执行幻灯片验证，预期条件将返回False，这将迫使它检查预期登录元素是否再次显示

您可以在代码中使用它，如下所示：

# Instantiate objects
driver = webdriver.Chrome()
wait = WebDriverWait(driver, 10)

# Load page and fill in input elements
driver.get("http://kthornbloom.com/slidetosubmit/")
driver.find_element(By.NAME, "name").send_keys("Fred")
driver.find_element(By.NAME, "email").send_keys("fred@example.com")

# Define slider elements and element that will be shown when you successfully log in
SLIDER_CONTAINER = (By.CSS_SELECTOR, ".slide-submit")
SLIDER = (By.CSS_SELECTOR, ".slide-submit-thumb")
ELEMENT_TO_FIND = (By.XPATH, "//div[.=\"Looks Like You're Human!\"]")

# Invoke the explicit wait that will deal with the slider if it is displayed
wait.until(wait_for_element_while_verifying_slider(ELEMENT_TO_FIND, SLIDER_CONTAINER, SLIDER))

上面的示例使用与上面相同的示例网站。要使其超时，您可以将
元素\u To\u FIND
更改为不存在的内容。要使其通过而不滑动，您可以将
元素\u修改为\u FIND
为：

ELEMENT_TO_FIND = (By.XPATH, "//div[.=\"Slide To Submit\"]")

使用您在评论中提供的代码，我希望以下内容可以在aliexpress网站上使用：

# Define slider elements and element that will be shown when you successfully log in
SLIDER_CONTAINER = (By.CSS_SELECTOR, ".nc-lang-cnt")
SLIDER = (By.CSS_SELECTOR, ".nc_wrapper .btn_slide")
ELEMENT_TO_FIND = (By.ID, "search-key")

# Invoke the explicit wait that will deal with the slider if it is displayed
wait.until(wait_for_element_while_verifying_slider(ELEMENT_TO_FIND, SLIDER_CONTAINER, SLIDER))

其他功能包括鼠标按下（
点击并按住（）
）、鼠标移动（
按偏移量移动（）
）和鼠标向上（
释放（）
）操作。是否可以共享用于登录的测试用户名和密码。也许您可以提供一个指向我可以使用的网站的url，并确保提供一个有效的解决方案？请不要为我显示滑块：（当您连续几次执行脚本时，会显示该滑块@Ardesco.Question更新以尝试帮助您解决此问题。您可能会使脚本更干净，但我将留给您：）
# Define slider elements and element that will be shown when you successfully log in
SLIDER_CONTAINER = (By.CSS_SELECTOR, ".nc-lang-cnt")
SLIDER = (By.CSS_SELECTOR, ".nc_wrapper .btn_slide")
ELEMENT_TO_FIND = (By.ID, "search-key")

# Invoke the explicit wait that will deal with the slider if it is displayed
wait.until(wait_for_element_while_verifying_slider(ELEMENT_TO_FIND, SLIDER_CONTAINER, SLIDER))
