```python
from selenium import webdriver
from selenium.webdriver.
chrome
.service import Service
from selenium.webdriver.
chrome
.options import Options
import json
# 启动
Chrome
chrome
_options = Options()
chrome
_options.add_argument('--headless')
chrome
_options.add_argument('--disable-gpu')
chrome
_options.add_argument('--no-sandbox')
chrome
_options.add_argument('--disable-dev-shm-usage')
chrome
_options.add_argument('--remote-debugging-port=9222')
chrome
_service = Service('/path/to/
chrome
driver')
chrome
_service.start()
driver = webdriver.Remote(
chrome
_options=
chrome
_options, command_executor=
chrome
_service.service_url)
# 获取视频性能指标
driver.get('https://example.com/video')
performance = driver.execute_cdp_cmd('Performance.getMetrics', {})
print(json.dumps(performance, indent=2))
# 关闭
Chrome
driver.quit()
chrome
_service.stop()
这段代码会启动一个无头
Chrome
，然后打开指定的 URL，获取视频的性能指标，并输出为 JSON 格式。你需要将 `/path/to/
chrome
driver` 替换为你本地的
Chrome
Driver 路径。
