来自 python selenium 的 .find_element() 问题

Question

I need to find the "upload" button and input to upload the video. Below is the markup of the elements and my code. Input field Upload button

import time
from selenium import webdriver
from selenium.webdriver.common.by import By

def test():
    driver = webdriver.Firefox()
    upload_url = "https://www.tiktok.com/upload?lang=en-EN"
    login_url = "https://www.tiktok.com/login"
    print("Log in manually and press ENTER", end = '')
    time.sleep(5)
    driver.get(login_url)
    driver.implicitly_wait(10)
    input()
    print("Loading upload page...")
    driver.get(upload_url)
    driver.implicitly_wait(10)
    path = ".../yt_to_tt_uploader/yt_videos/YMbO9YYzvVw.mp4"
    upload = driver.find_element(By.XPATH, "//input[@type='file']")
    upload.send_keys(path)
    upload_button = driver.find_element(By.XPATH, "//button[class='css-y1m958']")
    upload_button.click()

It's raising error

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: //input[@type = 'file']

I tried to find it by XPATH, CLASS_NAME, text, but maybe i was wrong. I need to upload video in the field and click "upload"

Selenium is not able to locate this element //input[@type='file'] in your code. Try using an explicit wait and see if it works, below code for your reference:

# wait 20 seconds before looking for element
upload = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.XPATH,"//input[@type='file']")))

If using presence_of_element_located doesn't work, then try visibility_of_element_located . Below is the code:

# wait 20 seconds before looking for element
upload = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH,"//input[@type='file']")))

Import statements required:

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

I see one more issue in your other XPath, @ is missing:

Change from //button[class='css-y1m958'] to //button[@class='css-y1m958']
