python中selenium动态切换ip的问题(如何使每次切换页面只切换ip但不打开谷歌浏览器)

Question

def ip_log(ip,port):
    PROXY = f"{ip}:{port}"  # 这里写你的代理

    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument('--proxy-server=%s' % PROXY)

题主意思是每次切换时桌面不显示浏览器窗口吧，否则你不打开它，无法获取数据的，如果想要隐藏浏览器界面，在选项中设置,

chrome_options = webdriver.ChromeOptions()

chrome_options.add_argument('--proxy-server=%s' % PROXY)

两行的后面加上下面一句即可。

chrome_options.add_argument('--headless')#不显示浏览器窗口
