python中应对各种机制

延迟机制

 from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
 
driver = webdriver.Firefox()
    driver.get('https://www.guiderank-app.com/goods-search?categoryId=14606257169901630856')
    my_element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.XPATH, '//*[@id="app"]/div[2]/div[3]/div/div[2]/div/div[1]/div[2]')))
    # elemen=driver.find_element(By.XPATH,'//div[contains(@class,"el-dialog__wrapper")]/*[contains(@class,"el-dialog myDialog")]/*[contains(@class,"el-dialog__body")]/*[contains(@class,"newuser")]/span').text
    print(my_element)

新框架：

browser=webdriver.Firefox()
browser.get("https://mail.qq.com/")
browser.switch_to.frame("login_frame")#切换到内嵌iframe
browser.find_element_by_class_name("inputstyle").send_keys("xxxxx")
pyautogui.hotkey('Tab')
browser.find_element_by_class_name("inputstyle.password").send_keys("xxxxx")
browser.switch_to.default_content()#回到默认的iframe
