问Python:[WinError 10060]连接尝试失败,因为连接方在一段时间后没有正确响应EN有时候,我们需要用到代理IP,比如在爬虫的时候,但是得到了IP之后,可能不知道怎么验证这些IP是不是有效的,这时候我们可以使用Python携带该IP来模拟访问某一个网站,如果多次未成功访问,则说明这个代理是无效的。 代码如下:
print(date,ip,'[Error 1] Authentication failed.\n',file = e1) 1. e1.close 1. except NetmikoTimeoutException : #登录超时报错记录 1. e2 = open(f'{date}.txt','a') 1. print(date,ip,'[Error 2] Connection timed out.\n',file = e2) ...
