使用python语言的selenium脚本编写一段代码:使用edge浏览器打开一个网页,打开100次,精确获取每次的加载时长,放在一个列表里,最后求平均加载时长

在Python中，我们可以使用Selenium库结合Edge浏览器和WebDriverWait来实现这个任务。首先，确保已安装了`selenium`, `webdriver_manager`以及对应的Edge浏览器驱动。这里以Windows环境为例，下载对应的`msedgedriver.exe`。

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

# 初始化driver
def setup_driver():
    options = webdriver.EdgeOptions()
    # 如果需要设置特定的隐身模式，可以添加下面这行
    # options.add_argument("headless")
    driver = webdriver.Edge(options=options)
    return driver

# 计算并存储页面加载时间
def measure_load_time(driver):
    url = "https://example.com"  # 替换为你想要打开的网页地址
    driver.get(url)
    
    try:
        element_to_wait = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.TAG_NAME, "html"))  # 等待页面元素加载完成
        )
        start_time = time.time()
        while True:
            if time.time() - start_time > 5:  # 设置一个较短的超时时间，防止无限循环
                break
        load_time = time.time() - start_time
    except Exception as e:
        print(f"Failed to measure load time: {e}")
        load_time = None

    return load_time

# 打开和测量页面100次
load_times = []
for _ in range(100):
    driver = setup_driver()
    load_time = measure_load_time(driver)
    if load_time is not None:
        load_times.append(load_time)
    driver.quit()

# 求平均加载时长
if load_times:
    average_load_time = sum(load_times) / len(load_times)
    print(f"Average page loading time: {average_load_time} seconds")
else:
    print("No valid load times recorded.")
