driver_path = r"D:\迅雷下载\geckodriver-v0.27.0-win64\geckodriver.exe"

driver = webdriver.Chrome
driver = webdriver.Firefox(executable_path=driver_path,desired_capabilities=header)
#会报错

报错：

就是代码的最后一行。
如果把desired_capabilities去掉就可以正常模拟访问网站了。但是我想给它添加一些请求头，请问要怎么添加

错误提示说的是headers 里有key 重复。 试试只保留

headers = {
    'User-Agent': UserAgent().random,
    'Connection': 'keep-alive',
    }

成功后，再逐条加上其他KEY
