Making a GET request in R

Question

I've been playing a little with httr and rcurl and cannot manage to translate the following curl GET request into R:

curl -X GET --header 'Accept: application/json' --header 'Authorization: Bearer 31232187asdsadh23187' 'https://this.url.api.com:334/api/endpoint'

Particularly, I've been having some trouble to pass the Authorization option as I was not able to find the equivalent parameter in neither of the libraries. It might be a custom header maybe?

Solution 1

Try out the new and further improving curlconverter package. It will take a curl request and output an httr command.

#devtools::install_github("hrbrmstr/curlconverter")

library(curlconverter)

curlExample <- "curl -X GET --header 'Accept: application/json' --header 'Authorization: Bearer 31232187asdsadh23187' 'https://this.url.api.com:334/api/endpoint'"

resp <- make_req(straighten(curlExample))
resp

Solution 2

httr::GET('https://this.url.api.com:334/api/endpoint', 
      accept_json(), 
      add_headers('Authorization' = 'Bearer 31232187asdsadh23187'))

Solution 3

I agree with sckott answer. I don't know too much about the maintenance and officiallity of curlconverter, but to complete httr function i will add few lines more.

getInfoInJson <- httr::GET('https://this.url.api.com:334/api/endpoint', 
      accept_json(), 
      add_headers('Authorization' = 'Bearer 31232187asdsadh23187'))

 #safe the info in a json object 
 jsonInfoImg <- content(getInfoInJson, type="application/json")

Hope it helps.

The curl converter is really cool! I will be trying this tomorrow and will get back to you to let you know whether it worked!

[jgozal]

this library is so cool! What has been your experience with it? do you always get good working curl conversions?

[jgozal]

sorry it took some time to get back to you. This request worked! although the curl converter that JackStat suggested makes making requests in R a piece of cake!

It is definitely a package that I foresee getting a lot of use. It is fairly new but I find it quite easy to pop in my curl requests and get a good chunk of httr code that I can use.
