如何使用 Python 3.6 从 HTML 中获取嵌入 YouTube 视频的代码

Question

我的目标是为在输入中搜索的视频创建一个文件下面的所有代码都有效，但是我找不到如何搜索 html 代码或将其写入 html 文件）。最终目标是让 YouTube discord 机器人之类的东西在本地工作。我需要提取用于嵌入视频的代码，而无需手动右键单击视频。 我会非常感谢那些提供帮助的人:)

import bs4 as bs

import urllib.request

import os

basic = 'https://www.youtube.com/'

search = ''

x = str(input('Song name: '))

y = ''

i = 0

x = x.split(' ')

y = x[0]

for i in range(1,len(x)):

    y = y + '+' + str(x[i])


searchQ = 'https://www.youtube.com/results?search_query='+y


sauce = urllib.request.urlopen(searchQ).read()
soup = bs.BeautifulSoup(sauce,'lxml')

nav = soup.nav

for url in soup.find_all('a'):
    z = (url.get('href'))
    i += 1
    if i > 10:
        if z[0] == '/' and z[1] == 'w':
            search = basic+z
            print(search)
            break
sauce = urllib.request.urlopen(search).read()
soup = bs.BeautifulSoup(sauce,'lxml')
page = urllib.request.urlopen(search)
html = page.read()
soup = bs.BeautifulSoup(html,'lxml')

os.remove('my vid.html')
f = open('my vid.html','w')
#f.write(str(html))
f.close


path = r'C:\Users\name\Desktop\my vid.html'
os.startfile(path)

Answer 1

我使用 selenium 来解决这个问题。而且我还删除了 requests 库的所有用法。

我的代码所做的是，它基本上进入任何 YouTube 视频并使用 selenium 复制嵌入代码并将代码输出到屏幕。

然后您可以稍后将嵌入代码以您想要的格式写入任何文件。这取决于你。

另外请注意，我没有触及与搜索视频或选择视频相关的任何内容。

代码：

import clipboard
import bs4 as bs
from selenium import webdriver
from selenium.webdriver import ActionChains

basic = 'https://www.youtube.com/'
search = ''
x = str(input('Song name: '))
y = ''
i = 0
x = x.split(' ')
y = x[0]

for i in range(1,len(x)):
    y = y + '+' + str(x[i])

searchQ = 'https://www.youtube.com/results?search_query=' + y
driver = webdriver.Chrome()
driver.get(searchQ)
driver.maximize_window()
soup = bs.BeautifulSoup(driver.page_source, 'lxml')
nav = soup.nav

for url in soup.find_all('a'):
    z = (url.get('href'))
    i += 1
    if i > 10:
        if z[0] == '/' and z[1] == 'w':
            search = basic+z
            print(search)
            break

driver.get(search)
soup = bs.BeautifulSoup(driver.page_source,'lxml')

actionChains = ActionChains(driver)
video = driver.find_element_by_css_selector('#movie_player > div.html5-video-container > video')
actionChains.context_click(video).perform()
embed = driver.find_element_by_xpath('//*[@id="null"]/div[3]/div[1]').click()
text = clipboard.paste()
print(text)

输入：

fire squad

输出：

Song name: fire squad
