I'm trying to POST data to JIRA Project using R and I keep getting: Error Bad Request. At first I thought it must be the JSON format that I created. So I wrote the JSON to file and did a curl command from console (see below) and the POST worked just fine. 

curl -D- -u fred:fred -X POST -d @sample.json -H "Content-Type: application/json" http://localhost:8090/rest/api/2/issue/

Which brings the issue to my R code. Can someone tell me what am I doing wrong with the RCurl postForm?

Source:

library(RJSONIO)
library(RCurl)

x <- list (
  fields = list(
  project = c(
     c(key="TEST")
  ),
  summary="The quick brown fox jumped over the lazy dog",
  description = "silly old billy",
  issuetype = c(name="Task")
 )
)


curl.opts <- list(
  userpwd = "fred:fred",
  verbose = TRUE,
  httpheader = c('Content-Type' = 'application/json',Accept = 'application/json'),
  useragent = "RCurl"           
)

postForm("http://jirahost:8080/jira/rest/api/2/issue/",
     .params= c(data=toJSON(x)),
     .opts = curl.opts,
     style="POST"
)

rm(list=ls()) 
gc()

Here's the output of the response:

You might find it easier to use httr which has been constructed with the needs of modern APIs in mind, and tends to set better default options. The equivalent httr code would be:

library(httr)

x <- list(
  fields = list(
    project = c(key = "TEST"),
    summary = "The quick brown fox jumped over the lazy dog",
    description = "silly old billy",
    issuetype = c(name = "Task")
  )
)

POST("http://jirahost:8080/jira/rest/api/2/issue/",
  body = RJSONIO::toJSON(x),
  authenticate("fred", "fred", "basic"),
  add_headers("Content-Type" = "application/json"),
  verbose()
)

If that doesn't work, you'll need to supply the output from a successful verbose curl on the console, and a failed httr call in R.
