Replicating curl command in babaska

Question

I have the following curl command from the github api that I wish to replicate in babashka:

curl \
  -X POST \
  -H "Accept: application/json" \
  -H "Authorization: Bearer <YOUR-TOKEN>" \
  https://api.github.com/user/repos \
  -d '{"name":"test"}'

Currently, I have tried:

(ns bb-test
 (require [environ.core :refer [env]]
          [babashka.curl :as curl])

(def url "https://api.github.com/user/repos")
(def token (env :token))
(def headers {"Accept" "application/json" "Authorization" (str "Bearer " token)})
(def body "{'name:' 'test'}")

(curl/post url {:headers headers :body body})

I get back a 400 http status code. Any help appreciated!

Answer 1

In the bash example, you're sending a body with {"name":"test"} as the literal data sent over the wire to the server.

With the babashka example, you're sending a body with {'name:' 'test'} as the literal data sent over the wire to the server.

Only one of these things is valid JSON.

The Clojure syntax to describe a literal string containing data {"name":"test"} is "{\"name\":\"test\"}", so the smallest change is to modify the line where you run def body:

(def body "{\"name\":\"test\"}")

Alternately, you can use a JSON library such as Cheshire to encode a native Clojure structure into a JSON string:

(ns bb-test
 (require [environ.core :refer [env]]
          [cheshire.core :as json]
          [babashka.curl :as curl])

(def url "https://api.github.com/user/repos")
(def token (env :token))
(def headers {"Accept" "application/json"
              "Authorization" (str "Bearer " token)})
(def body {"name" "test"})

(curl/post url {:headers headers
                :body (json/generate-string body)})
