作为深夜项目的一部分,我正在努力工作,我正试图从他们的网站上删除我的Uber旅行数据。
我已经看过
上登录页面的代码了并且已经看到他们在表单设置中使用POST方法如下:
<form method="post" class="form" novalidate="">
<input type="hidden" name="_csrf_token" value="1452201446-01-hujzoBTxkYPrJessd6zQwnD2ZOFxMOVgIYN8iXntr6c=">
<input type="hidden" data-js="access-token" name="access_token">
<a href="#" class="btn btn--full btn--facebook" data-js="facebook-connect">
<span class="push--ends flush">Continue with Facebook</span>
</a>
<p class="primary-font primary-font--semibold text-uber-white background-line push--top push--bottom">
<span>or use email</span>
</p>
<div class="form-group push-tiny--top flush--bottom">
<input type="email" name="email" class="text-input square--bottom " placeholder="Email Address" value="" id="email">
</div>
<div class="form-group push--bottom">
<input type="password" name="password" class="text-input square--top " placeholder="Password" id="password">
</div>
我读到的是,在尝试刮取
时需要发送csrf令牌library(RCurl)
library(XML)
URL_str<-"https://login.uber.com/login"
URL_str2<-"https://riders.uber.com/trips"
email<-"exampleMail@gmail.com"
pass<-"thisisalong"
token<- "1452201446-01-hujzoBTxkYPrJessd6zQwnD2ZOFxMOVgIYN8iXntr6c="
params <- list('email' = email,
'password' = pass,
'_csrf_token'=token)
URL_doc = postForm(URL_str2, style="POST",
.params=params)
如果我现在尝试抓住网站,我会
ERROR: FORBIDDEN
我在python中看到过类似网站的一些例子。可以在R中完成同样的工作吗?
答案 0 :(得分:0)
最后的答案最终很简单:
library(rvest)
library(RCurl)
library(XML)
session <-html_session("https://login.uber.com/login")
email<-"exampleMail@gmail.com"
pass<-"thisisalong"
#Handling the html_form
form<-html_form(session)[[1]]
form<-set_values(form, email=email, password=pass)
#Found that unless I explicitly assigned the value to empty it created errors
form$url<-""
session_open<-submit_form(session,form)
session_open<-jump_to(session_open,URL_str2)
从此处开始使用html_table
直接拉动表并使用html_nodes
隔离节点。希望这有帮助
