将 youtube 频道名称添加到评论中

Question

我想让 selenium 脚本评论带有特定关键字的视频。 但是我也想让它说出频道名称，如果可能的话，有人可以帮我吗？谢谢。

（我知道 {} 不应该在那里，但它会让您知道将频道名称放在哪里）

（频道名称将在 {}s btw 之间）

这里是代码。

import time

from bs4 import BeautifulSoup
from selenium import webdriver

def youtube_login(email,password):

    op = webdriver.ChromeOptions()
    op.binary_location = os.environ.get("GOOGLE_CHROME_BIN")
    #op.add_argument('--headless')
    op.add_argument('--disable-dev-shm-usage')
    op.add_argument('--no-sandbox')
    driver = webdriver.Chrome()
    driver.get('https://accounts.google.com/ServiceLogin?hl=en&continue=https%3A%2F%2Fwww.youtube.com%2Fsignin%3Fhl%3Den%26feature%3Dsign_in_button%26app%3Ddesktop%26action_handle_signin%3Dtrue%26next%3D%252F&uilel=3&passive=true&service=youtube#identifier')

    driver.find_element_by_id('identifierId').send_keys(email)
    driver.find_element_by_id('identifierNext').click()
    time.sleep(3)
    #WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'div#password input[name="password"]')))
    driver.find_element_by_css_selector('div#password input[name="password"]').send_keys(password)
    time.sleep(4)
    driver.find_element_by_id('passwordNext').click()

    return driver

def comment_page(driver,urls,comment):

    if len( urls ) == 0:
        print ('Youtube Comment Bot: Finished!')
        return []
    
    url = urls.pop()
    
    driver.get(url)
    print(url)

    )
    post.click()

    r = np.random.randint(2,5)
    time.sleep(r)

    return comment_page(driver, urls, random_comment())

    except NoSuchElementException:

    return True

if __name__ == '__main__':
# You should edit these lines=======
    email = 'Youremail@gmail.com'
    password = 'Yourpassword'

    urls = [

    ]
    
    inp = open("url.txt","r")
    for line in inp.readlines():
            urls.append(line)
    

    driver = youtube_login(email, password)

    comment_page(driver,urls,random_comment())

Answer 1

这里是获取频道名称的定位器：

//div[contains(@class, 'channel-name')]//a

您现在要做的就是获取文本并将其替换为您的字符串。
