import logging from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

这段代码是用于导入 Python 中的 logging 模块以及 Selenium 的 DesiredCapabilities 类。logging 模块用于记录程序运行时的日志，而 DesiredCapabilities 类则用于设置浏览器的各种参数和选项，例如浏览器类型、版本、语言、是否启用 JavaScript 等等。一般来说，在使用 Selenium 进行自动化测试时，需要先创建一个 DesiredCapabilities 对象，并设置好所需的参数，然后再将该对象传递给 webdriver.Remote() 方法，以启动一个远程浏览器实例。

webdriver.Chrome() 怎么设置请求次数

您可以使用以下代码来设置请求次数：

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.CHROME
caps['loggingPrefs'] = {'performance': 'ALL'}

options = webdriver.ChromeOptions()
options.add_argument('--ignore-certificate-errors')

selenium打开edge时，怎么和chrome一样进行edge的初始设置

在Selenium中，如果你想要像操作Chrome浏览器那样初始化Edge浏览器，并进行一些预设的设置，你需要使用WebDriverManager来管理浏览器驱动。WebDriverManager是一个方便的工具库，可以自动下载并管理浏览器驱动，包括Microsoft Edge。

以下是使用Python示例代码：

from selenium import webdriver
from selenium.webdriver.edge.options import Options
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

# 创建Edge选项
options = Options()
options.add_argument('--edge-launch-mode=hub')  # 设置启动模式为边缘浏览器的Hub模式
options.add_experimental_option('excludeSwitches', ['enable-logging'])  # 关闭日志记录，以避免输出过多信息

# 如果需要，你可以添加特定的配置，如语言、代理等
options.set_edge_user_agent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36 Edg/99.0.1150.30")

# 初始化Driver
driver = webdriver.Edge(service_log_path=None, options=options)
driver.get("https://www.example.com")  # 打开初始URL

# 进行你的页面操作...
# ...

# 关闭浏览器
driver.quit()
