I've got a local server running on port 8545 which listen to JSON-RPC requests. I can call it using curl like this:
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBalance","params":["0xf54c19d9ef3873bfd1f7a622d02d86249a328f06", "latest"],"id":1}' http://localhost:8545
What would be the equivalent call from Clojure? Do I need to add some external libraries to the project.clj?
I think you should try http-kit. Also you will need some library for json (data.json or cheshire)
So add to your project.clj
following dependencies:
And try this
(ns your-ns
(:require [org.httpkit.client :as http]
[clojure.data.json :as json]))
(let [url "http://localhost:8545"
body (json/write-str
{:jsonrpc "2.0"
:method "eth_getBalance"
:params ["0xf54c19d9ef3873bfd1f7a622d02d86249a328f06" "latest"]
:id 1})
options {:body body}
result @(http/post url options)]
(prn result))
