在 YouTube 上搜索并返回 Python 中的所有链接 [英] Search on YouTube and return all links in Python

问题描述

在 YouTube 上，我想搜索某些视频(即 Python 上的视频)，然后，我想返回此搜索返回的所有视频.现在如果，我尝试这个 Python 返回起始页上的所有视频，而不是搜索后的页面.

On YouTube, I want to search for certain videos (i.e. videos on Python) and after this, I want to return all videos this search returns. Right now if, I try this Python returns all the videos on the start page not on the page after the search.

当前代码:

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("http://youtube.com")
driver.find_element_by_name("search_query").send_keys("Python")
driver.find_element_by_id("search-icon-legacy").click()
links = driver.find_elements_by_id("video-title")
for x in links:
    print(x.get_attribute("href"))

这里出了什么问题?

推荐答案

要从搜索中返回关键字为 Python 的所有视频，您需要:

To return all videos from the search with the keyword as Python you need to:

• 最大化屏幕，以便在 HTML DOM 中呈现所有结果视频链接.
• 在提取 href 属性之前，诱导 WebDriverWait 使所需的元素可见.

• 您可以使用以下解决方案

• Maximize the screen so all the resultant video links get rendered within the HTML DOM.
• Induce WebDriverWait for the desired elements to be visible before extracting the href attributes.

• You can use the following solution

• 代码块:

• Code Block:

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

options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("https://www.youtube.com/")
WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#search"))).send_keys("Python")
driver.find_element_by_css_selector("button.style-scope.ytd-searchbox#search-icon-legacy").click()
print([my_href.get_attribute("href") for my_href in WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "a.yt-simple-endpoint.style-scope.ytd-video-renderer#video-title")))])

控制台输出:
