Question

我想運行代碼登錄到gmail.com，但登錄過程似乎已經改變。我修改了以下代碼，但不斷收到以下錯誤：selenium.common.exceptions.NoSuchElementException：消息：無法找到元素：{「method」：「id」，「selector」：「Passwd」} 任何人都看到或者知道我做錯了什麼。由於

from selenium import webdriver 
browser = webdriver.Firefox() 
browser.get('http://gmail.com') 
emailElem = browser.find_element_by_id('Email') 
emailElem.send_keys('some_email@gmail.com') 
nextElem = browser.find_element_by_id('next') 
nextElem.click()    # click the button 
passwordElem = browser.find_element_by_id('Passwd') 
passwordElem.send_keys('password') 
passwordElem.submit() 

Answer 1

您需要wait的元素的存在與id="Passwd"：

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

wait = WebDriverWait(browser, 10) 
passwordElem = wait.until(EC.presence_of_element_located((By.ID, "Passwd"))) 
passwordElem.send_keys('password') 
passwordElem.submit()
