我在使用 selenium 更改 Python 中的 Web 驱动程序用户代理时遇到错误。
这是我的代码：
import requests
import json
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
#Error is on line above
这是我的错误：
>>> driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent":"python 3.7", "platform":"Windows"})
File "<stdin>", line 1
driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent":"python 3.7", "platform":"Windows"})```
你的代码只是perfect。您只需编写一行代码即可更改用户代理 /questions/tagged/user-agent在下一行。举个例子：
-
代码块：
from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
print(driver.execute_script("return navigator.userAgent;"))
# Setting user agent as Chrome/83.0.4103.97
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
print(driver.execute_script("return navigator.userAgent;"))
# Setting user agent as Chrome/83.0.4103.53
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.53 Safari/537.36'})
print(driver.execute_script("return navigator.userAgent;"))
driver.get('https://www.httpbin.org/headers')
