使用rvest通过登录页面刮取网站

Question

这是我的代码:

library(rvest)

#login
url <- "https://secure.usnews.com/member/login?ref=https%3A%2F%2Fpremium.usnews.com%2Fbest-graduate-schools%2Ftop-medical-schools%2Fresearch-rankings"
session <- html_session(url)

form <- html_form(read_html(url))[[1]]

filled_form <- set_values(form,
                          username = "notmyrealemail",
                          password = "notmyrealpassword")

submit_form(session, filled_form)

这是我得到的输出后submit_form:

<session> https://premium.usnews.com/best-graduate-schools/top-medical-schools/research-rankings
  Status: 200
  Type:   text/html; charset=utf-8
  Size:   286846

我认为这意味着它有效吗？如果是这样,我如何read_html在登录后出现的页面上？

Answer 1

Nvm,通过使用它来工作 url <- jump_to(session, "https://premium.usnews.com/best-graduate-schools/top-medical-schools/research-rankings")
