selenium处理H5视频主要使用的是javascript，javascript函数有内置的对象叫arguments，arguments包含了调用的参数组，[0]代表取第一个值。
currentSrc 返回当前音频或视频的URL，如果未设置则返回空字符串。
load(),play(),pause()代表视频的加载，播放，停止。
示例1：
from selenium import webdriver from time sleep dr = webdriver.Chrome() dr.get('https://www.videojs.com') dr.implicitly_wait(10) video = dr.find_element_by_css_selector("#vjs_video_3_html5_api") url = dr.execute_script(return arguments[0].currentSrc;,video) print(url) print(start) dr.execute_script(return arguments[0].play()) stopreturn arguments[0].pause()代码报错如下：blob:https://videojs.com/905716de-68da-493b-b78d-0a56ea256ee2 start Traceback (most recent call last): File js.py",line 11,in <module> dr.execute_script(F:\python3.7\lib\site-packages\selenium\webdriver\remote\webdriver.pyin execute_script args': converted_args})[value] File execute self.error_handler.check_response(response) File F:\python3.7\lib\site-packages\selenium\webdriver\remote\errorhandler.py check_response raise exception_class(message,screen,stacktrace) selenium.common.exceptions.JavascriptException: Message: javascript error: play() Failed because the user didnt interact with the document first. https://goo.gl/xX8pDD (Session info: chrome=83.0.4103.61)解决思路，模拟手动点击播放
