无法将密钥发送到 twitter xpath

Question

将密钥发送到 twitter xpath 会出现错误
Twitter 今天更新了用户界面，这会是问题的原因吗？试图找到 iframe 看看是否需要切换，但找不到任何

我正在运行的代码

from selenium import webdriver
import time
from selenium.webdriver.common.by import By
Driver = webdriver.Chrome()

Driver.get('https://x.com/i/flow/login')
time.sleep(3)
username = Driver.find_element(By.XPATH,'//*[@id="react-root"]/div/div/div/main/div/div/div/div[2]/div[2]/div/div[4]/label/div/div[2]')
username.send_keys('test')
time.sleep(2)

期望用户名区域为“test”

Answer 1

//*[@id="react-root"]/div/div/div/main/div/div/div/div[2]/div[2]/div/div[4]/label/div/div[2]

以上 XPath 表达式不正确。它不定位任何元素。因此

no such element

例外。

登录页面只有一个

<input>

元素。所以你可以使用

TAG_NAME

定位器策略。

参考下面的工作代码：

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

driver = webdriver.Chrome()
driver.get("https://twitter.com/i/flow/login")
driver.maximize_window()
wait = WebDriverWait(driver, 10)
username = wait.until(EC.element_to_be_clickable((By.TAG_NAME, "input")))
username.send_keys('test')
time.sleep(10)

建议：使用 Selenium 的 waits 而不是

time.sleep()

。最后一行

time.sleep(10)

只是为了让您看到在页面上输入的文本，您不需要它。
