我想使用RCurl登录网站并从网上获取数据(没有登录就无法看到数据.)
我想导出这个(例如)" http://www.appannie.com/app/ios/instagram/ranking/history/chart_data/?s=2010-10-06&e=2012-06-04&c=143441&f=ranks&d在我使用RCurl登录后,= iphone "进入R".问题是我无法使用RCurl登录.我之前没有尝试过,所以大多数时候我都提到了http://www.omegahat.org/RCurl/philosophy.html.
所以这就是我的尝试.(这里,'me@gmail.com'是我的用户ID,'9999'是我的密码 - 我刚刚完成了.)
library(RJSONIO)
library(rjson)
library(RCurl)
appannie <- getURL("http://www.appannie.com/app/ios/instagram/ranking/history/chart_data/.json?s=2010-10-06&e=2012-06-04&c=143441&f=ranks&d=iphone, userpwd = me@gmail.com:9999", verbose = TRUE)
但这给了我以下信息:
