我正在尝试使用 selenium 浏览器 python 获取 facebook 帐户的数据，但无法找到单击导出按钮时可以查看的元素.

I'm trying to fetch data for facebook account using selenium browser python but can't able to find the which element I can look out for clicking on an export button.

见附件截图

我试过了，但它似乎给了我上课的错误.

I tried but it seems giving me an error for the class.

def login_facebook(self, username, password):
    chrome_options = webdriver.ChromeOptions()
    preference = {"download.default_directory": self.section_value[24]}

    chrome_options.add_experimental_option("prefs", preference)
    self.driver = webdriver.Chrome(self.section_value[20], chrome_options=chrome_options)
    self.driver.get(self.section_value[25])

    username_field = self.driver.find_element_by_id("email")
    password_field = self.driver.find_element_by_id("pass")

    username_field.send_keys(username)
    self.driver.implicitly_wait(10)

    password_field.send_keys(password)
    self.driver.implicitly_wait(10)

    self.driver.find_element_by_id("loginbutton").click()
    self.driver.implicitly_wait(10)

    self.driver.get("https://business.facebook.com/select/?next=https%3A%2F%2Fbusiness.facebook.com%2F")
    self.driver.get("https://business.facebook.com/home/accounts?business_id=698597566882728")
    self.driver.get("https://business.facebook.com/adsmanager/reporting/view?act="
                    "717590098609803&business_id=698597566882728&selected_report_id=23843123660810666")
    # self.driver.get("https://business.facebook.com/adsmanager/manage/campaigns?act=717590098609803&business_id"
    #                 "=698597566882728&tool=MANAGE_ADS&date={}-{}_{}%2Clast_month".format(self.last_month,
    #                                                                                      self.first_day_month,
    #                                                                                      self.last_day_month))

    self.driver.find_element_by_id("export_button").click()
    self.driver.implicitly_wait(10)
    self.driver.find_element_by_class_name("_43rl").click()
    self.driver.implicitly_wait(10)

您能告诉我如何点击导出按钮吗?

Can you please let me know how can i click on Export button?

推荐答案

文本为Export的元素是动态生成的元素，所以要定位到元素需要诱导WebDriverWait 使 元素可点击 ，您可以使用 定位器策略:

The element with text as Export is a dynamically generated element so to locate the element you have to induce WebDriverWait for the element to be clickable and you can use either of the Locator Strategies:

• 使用 CSS_SELECTOR:

WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.layerConfirm>div[data-hover='tooltip'][data-tooltip-display='overflow']"))).click()

使用 XPATH:

WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[contains(@class, 'layerConfirm')]/div[@data-hover='tooltip' and text()='Export']"))).click()

注意:您必须添加以下导入:

Note : You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
