如何使用python selenium处理模态登录

Question

我试图使用登录到一个网站。但是登录在引导模式对话框中，我无法使用我的代码成功登录。有人能告诉我我的密码出了什么问题吗？

我尝试了以下代码：

import requests
import time
import os, sys

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver import ActionChains

gecko = os.path.normpath(os.path.join(os.path.dirname(__file__), 'geckodriver'))
binary = FirefoxBinary(r'C:/Program Files/Mozilla Firefox/firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary, executable_path=gecko +'.exe')
driver.maximize_window() 
wait = WebDriverWait(driver, 10) 
time.sleep(1)

pageurl = "https://www.producemarketguide.com"
driver.get(pageurl)

popup = wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@id="close-dialog"]')))
popup.click()

time.sleep(2)
login = wait.until(EC.element_to_be_clickable((By.XPATH, '/html/body/div[1]/header/div/div[2]/div[2]')))
login.click()

user = wait.until(EC.presence_of_element_located((By.XPATH, '/html/body/app-main/app-widget/screen-layout/main/current-screen/div/screen-login/p[3]')))
user.send_keys('xxx@gmail.com')

password = wait.until(EC.presence_of_element_located((By.XPATH, '/html/body/app-main/app-widget/screen-layout/main/current-screen/div/screen-login/p[4]/input')))
password.send_keys('XXXX')

submit = wait.until(EC.element_to_be_clickable((By.XPATH, '/html/body/app-main/app-widget/screen-layout/main/current-screen/div/screen-login/p[6]/button')))
submit.click() 

我得到的错误信息是

Traceback (most recent call last):

    raise TimeoutException(message, screen, stacktrace)

该模式对话框是一个iframe，因此您需要切换到iframe以输入凭据，请尝试以下代码：

accept_cookies = driver.find_element(By.CSS_SELECTOR, "button#onetrust-accept-btn-handler")
if accept_cookies.is_displayed():
    accept_cookies.click()
else:
    print("Accept Cookies button not displayed")

popup_dialog = driver.find_element(By.ID,"popup-dialog-window")
close_icon = driver.find_element(By.ID, "close-dialog")
if popup_dialog.is_displayed():
    close_icon.click()
else:
    print("Welcome dialog not displayed")

time.sleep(1)
# Clicking Login/Register link
driver.find_element(By.CSS_SELECTOR, ".user-login.user-login-front.pull-right #user-piano-login-register").click()
time.sleep(1)

# Switch to the login dialog iframe
driver.switch_to.frame(driver.find_element(By.XPATH,".//iframe[starts-with(@id,'piano-id-')]"))

# enter the credentials and click Login button
driver.find_element(By.XPATH,".//input[@fieldloginemail]").send_keys("emailid")
time.sleep(0.5)
driver.find_element(By.XPATH,".//input[@fieldloginpassword]").send_keys("password")
time.sleep(0.5)
driver.find_element(By.XPATH,".//button[@actionlogin]").click()
