如何为 scrapy（爬行）找到元素 iTunes Connect 网站？

Question

我需要我的应用程序的 CFBundleversion，所以我尝试了 scrapy iTunes Connect 网站，但我无法获取元素。

我试过了：

from selenium import webdriver

driver = webdriver.Firefox()

driver.get("https://appstoreconnect.apple.com/login")

elem = driver.find_element_by_xpath("//input[@id='account_name_text_field']")

我收到以下错误：

elenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: //input[@id='account_name_text_field']

我认为网站结构不同... 我该怎么办？

Answer 1

你的定位器没问题:

driver.find_element_by_xpath("//input[@id='account_name_text_field']")

在iframe里面，需要先切换，使用frame_to_be_available_and_switch_to_it和visibility_of_element_located，像这样：

driver.get('https://appstoreconnect.apple.com/login')

WebDriverWait(driver, 30).until(expected_conditions.frame_to_be_available_and_switch_to_it((By.ID, "aid-auth-widget-iFrame")))
WebDriverWait(driver, 30).until(expected_conditions.visibility_of_element_located((By.XPATH, "//input[@id='account_name_text_field']")))
elem = driver.find_element_by_xpath("//input[@id='account_name_text_field']")
elem.send_keys("userName")

以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions
