如何在 Python 中使用 Selenium 在 YouTube 上搜索和播放视频？

Question

我想在 Python 中使用 Selenium 搜索和播放视频。
这是代码：

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

driver = webdriver.Chrome()
driver.maximize_window()
driver.get(www.youtube.com)

wait = WebDriverWait(driver, 3)
presence = EC.presence_of_element_located
visible = EC.visibility_of_element_located

# Search for the video.
time.sleep(1)
wait.until(visible((By.NAME, "search_query")))
driver.find_element_by_name("search_query").click()
driver.find_element_by_name("search_query").send_keys(video)
driver.find_element_by_id("search-icon-legacy").click()

# Play the video.
wait.until(visible((By.ID, "video-title")))
driver.find_element_by_id("video-title").click()

但问题是，它在完成搜索之前播放主页上的第一个视频。
你们能建议如何播放视频吗？

Answer 1

您可以通过将所需的搜索查询附加到 search_query 参数来完全绕过从主页开始的需要:)

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

driver = webdriver.Chrome()
driver.maximize_window()

wait = WebDriverWait(driver, 3)
presence = EC.presence_of_element_located
visible = EC.visibility_of_element_located

# Navigate to url with video being appended to search_query
driver.get('https://www.youtube.com/results?search_query={}'.format(str(video))

# play the video
wait.until(visible((By.ID, "video-title")))
driver.find_element_by_id("video-title").click()
