如何使用 Selenium Post Youtube 评论

Question

我正在尝试 post 使用 Selenium 的 Youtube 评论。以下是代码的要点（省略了关于登录 Google 的行）：

comment_url = "https://www.youtube.com/all_comments?v=LAr6oAKieHk"
profile = webdriver.FirefoxProfile()
driver = webdriver.Firefox(firefox_profile=profile)

driver.get(comment_url)
assert "All comments" in driver.title

textbox = driver.find_element_by_class_name("box")
textbox.click()
textbox.send_keys("My comment")

textbox.click() 按预期工作并将焦点设置到评论框。但是，textbox.send_keys("My comment") 并没有将文本输入到框中，而是以某种方式将焦点移开。

谁能给点建议？

首先，您需要单击该框以使其可编辑。然后，switch to the appropriate iframe and set the innerHTML attribute of an underlying "textbox". You also have to use Explicit Waits 贯穿整个代码，因为 youtube 大量使用 AJAX 并且每个操作都会发生异步动态 DOM 更新：

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

comment = 'test'

box = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CLASS_NAME, "box")))
box.click()

frame = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, '//iframe[@title="+1"]')))
driver.switch_to.frame(frame)

driver.find_element_by_xpath('//div[@onclick]').click()

element = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, '//div[@jsname="msEQQc"]/following-sibling::div//div[@g_editable="true"]')))
driver.execute_script("arguments[0].innerHTML='%s';" % comment, element)

完整代码（含鉴权）：

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


driver = webdriver.Firefox()
driver.get('https://accounts.google.com/ServiceLogin?continue=https%3A%2F%2Fwww.youtube.com%2Fsignin%3Fhl%3Den%26feature%3Dcomment%26app%3Ddesktop%26next%3D%252Fall_comments%253Fv%253DLAr6oAKieHk%26action_handle_signin%3Dtrue&uilel=3&service=youtube&passive=true&hl=en')

# log in
driver.find_element_by_id('Email').send_keys('username')
driver.find_element_by_id('Passwd').send_keys('password')
driver.find_element_by_id('signIn').click()

# post a comment
comment = "test"

box = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CLASS_NAME, "box")))
box.click()

frame = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, '//iframe[@title="+1"]')))
driver.switch_to.frame(frame)

driver.find_element_by_xpath('//div[@onclick]').click()

element = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, '//div[@jsname="msEQQc"]/following-sibling::div//div[@g_editable="true"]')))
driver.execute_script("arguments[0].innerHTML='%s';" % comment, element)
