我将 Perl 与 Selenium 一起使用。我已经设置了 $sel->set_timeout("86400000");。
打开内容较多的网站时，显示500读取超时消息。有人可以帮我吗？

在我看来，不是 Selenium Webdriver（客户端）发出超时，而是 Web 服务器等待太久了。
你想完成什么？也许您可以发出 HTTP HEAD 请求来检查您的 URL 是否有效？ （HEAD 请求不会返回任何内容，只是返回带有 http 状态代码的 HTTP 标头以及可选的“Content-Length”标头以及其他字段。HEAD 请求比 GET 或 POST 请求和您不会遇到超时问题。例如，如果您的请求被重定向到另一台服务器，
那么我现在无法帮助您。 足够的信息。
您可以使用 用于创建 HEAD 请求的 Test::WWW::Mechanize 对象（它是 LWP::Request 的子类）不确定 selenium 是否支持 head 请求。
It seems to me that not the Selenium webdriver (the client) has issued the timeout, but the webserver has been waiting too long.
What do you want to accomplish? Maybe you can just make a HTTP HEAD request to check that your URL is valid? (A HEAD request does not give you any content back, just the HTTP header with the http status code and, optionally, the "Content-Length" header, among other fields. The HEAD request is much faster that a GET or POST request and yo won't have problems with timeouts. You might get more than one HEAD respnses e.g. if your request is redirected to another server.
Or do you want to check the large content itself. Then I cannot help you at this point. There is not enough information.
You can use a Test::WWW::Mechanize object to create the HEAD request (it is a subclass of LWP::Request). NOt sure if selenium supports head requests.
