Question

我尝试登录安全（HTTPS）服务器。当我使用互联网浏览器输入用户名和密码时，浏览器会将我发送到与登录屏幕之后的下一个URL对应的网页。当我通过getURL()输入用户密码时，我很难找到下一个网址。以下是R脚本以及服务器和客户端之间的交换。隐藏的下一个URL在哪里？

library(RCurl)
library(XML)
library(bitops)
options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))
html_form = getURL(url1, userpwd = "my_userID:my_password", verbose = TRUE)

verbose选项在客户端/服务器交换上提供以下日志：

您正在使用HTTP身份验证设置用户名和密码，而您尝试登录的网站正在使用表单进行登录。它还使用JavaScript来进行登录的POST。如果你想让它工作，你可能最好使用你最喜欢的网络浏览器的开发者模式，登录并在Net选项卡中查看登录期间发布的内容。然后，您可以使用httr包来发布类似的登录信息。

原始问题的答案是302响应的重定向位于“位置”字段中，但所有操作都要求您再次登录！

如何在R中找到我的下一个URL？
