Cookie request using R

I'm trying to convert the following curl command into httr/RCurl to get a cookie into R. But I'm not sure how to pass the data "j_username=username&j_password=password" using getURL(...) or GET(...)

curl --data "j_username=username&j_password=password" http://localhost:8080/myApp/j_spring_security_check --cookie-jar cookies.txt

I'm able to get the cookie information created by command line curl command above and paste it into the GET request (it works). If I could generate the cookie within R it would be convenient.

Here's my working httr get GET():

GET(dataURL,
   verbose(),
   add_headers("Content-type"="application/json",
               "Accept"="application/json",
               "Accept-Version"=" 1.0",
               "Cookie"="JSESSIONID=24BA7A80A02317AD2B6C87C8D10B6787"
               )
    )
Solution

  • It's hard to tell without a reproducible example, but I think the httr code you want is this:

    library(httr)
baseUrl <- "http://localhost:8080/myApp/"

POST(baseUrl, path = "j_spring_security_check", 
  body = list(j_username = "username", j_password = "password"),
  multipart = FALSE,
  verbose()
)

headers <- add_headers(
  "Content-Type" = "application/json", 
  Accept = "application/json",
  "Accept-Version" = "1.0"
)

GET(baseUrl, headers, verbose())

    httr automatically sets up the handle to preserve cookies within a domain.
