Ruby send JSON request

Question

How do I send a JSON request in ruby? I have a JSON object but I dont think I can just do .send. Do I have to have javascript send the form?

Or can I us

Answer 1

data = {a: {b: [1, 2]}}.to_json
uri = URI 'https://myapp.com/api/v1/resource'
https = Net::HTTP.new uri.host, uri.port
https.use_ssl = true
https.post2 uri.path, data, 'Content-Type' => 'application/json'

Answer 2

A simple json POST request example for those that need it even simpler than what Tom is linking to:

require 'net/http'

uri = URI.parse("http://www.example.com/search.json")
response = Net::HTTP.post_form(uri, {"search" => "Berlin"})

Answer 3

I like this light weight http request client called `unirest'

gem install unirest

usage:

response = Unirest.post "http://httpbin.org/post", 
                        headers:{ "Accept" => "application/json" }, 
                        parameters:{ :age => 23, :foo => "bar" }

response.code # Status code
response.headers # Response headers
response.body # Parsed body
response.raw_body # Unparsed body

Answer 4

uri = URI('https://myapp.com/api/v1/resource')
req = Net::HTTP::Post.new(uri, 'Content-Type' => 'application/json')
req.body = {param1: 'some value', param2: 'some other value'}.to_json
res = Net::HTTP.start(uri.hostname, uri.port) do |http|
  http.request(req)
end
