使用Selenium自动下载YouTube MP3时点击下载按钮失败求助

我想用Selenium自动化从https://ytmp4converter.com/下载YouTube视频的MP3版本，但点击下载按钮时遇到TimeoutException错误。

我的代码 #

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
from selenium.webdriver.common.keys import Keys
import time


PATH = "C:\\Program Files (x86)\\chromedriver.exe"
driver = webdriver.Chrome(PATH)

driver.get("https://ytmp4converter.com/")


#How to access elements on the page
#Id, name, class is the hierachical way of searching for specific element within HTML

search = driver.find_element("name", "url")
#Now what this will do is it will return to as an object that represents that search bar
#that we can actually interact with and mess around

search.send_keys("https://www.youtube.com/watch?v=BQogzYUoQWU&list=RDBQogzYUoQWU&start_radio=1") #This sends input on the search bar e.g "test"
search.send_keys(Keys.RETURN) #This is the computer version of pressing the "Enter" button

#/download.php?source=youtube&media=OA==
#link = driver.find_element(By.LINK_TEXT, "https://ytmp4converter.com/en/wp-content/plugins/aio-video-downloader/download.php?source=youtube&media=OA==")
#link.click()

wait = WebDriverWait(driver, 20)
element = wait.until(EC.presence_of_element_located((By.LINK_TEXT, "https://ytmp4converter.com/en/wp-content/plugins/aio-video-downloader/download.php?source=youtube&media=OA==" )))
element.click()

下载按钮HTML截图 #

核心问题 #

你用By.LINK_TEXT匹配完整下载URL的方式完全错误：LINK_TEXT是用来匹配a标签的可见文本内容，而非href属性值。从截图看，下载按钮的可见文本应该是类似"Download MP3"的内容，不是完整URL。另外，这类网站的下载链接参数（比如media=OA==）是动态生成的，每次转换都会变化，硬编码完整URL根本无法复用。

修复步骤 #

1. 更换定位方式：用CSS选择器或XPATH匹配href包含固定关键词的a标签，或者直接匹配按钮的可见文本。
2. 等待元素可点击：用EC.element_to_be_clickable代替EC.presence_of_element_located，确保元素不仅存在，还处于可交互状态。
3. 兼容动态参数：避免硬编码完整URL，通过通用特征定位元素。

修复后的代码 #

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
from selenium.webdriver.common.keys import Keys

PATH = "C:\\Program Files (x86)\\chromedriver.exe"
driver = webdriver.Chrome(PATH)

driver.get("https://ytmp4converter.com/")

# 输入YouTube链接并提交
search = driver.find_element(By.NAME, "url")
search.send_keys("https://www.youtube.com/watch?v=BQogzYUoQWU&list=RDBQogzYUoQWU&start_radio=1")
search.send_keys(Keys.RETURN)

# 等待下载按钮可点击，通过href包含download.php的特征定位
wait = WebDriverWait(driver, 20)
# 也可以用文本定位：EC.element_to_be_clickable((By.LINK_TEXT, "Download MP3"))
download_btn = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a[href*='download.php']")))
download_btn.click()

# 可选：如果下载链接在新窗口打开，切换到新窗口继续操作
# windows = driver.window_handles
# driver.switch_to.window(windows[-1])

额外提示 #

• 这类转换网站通常会有广告弹窗，必要时需要添加弹窗关闭逻辑，比如检查并关闭iframe内的广告。
• 确保ChromeDriver版本与Chrome浏览器版本完全匹配，避免兼容性问题。
