make a http request with a custom body in ruby

To make an HTTP request with a custom body in Ruby, you can use the Net::HTTP library, which is included in the Ruby standard library. Here's an example for making a POST request with a JSON body:

main.rb
require 'uri'
require 'net/http'
require 'json'

uri = URI.parse("https://example.com/api/endpoint")
headers = {'Content-Type' => 'application/json'}

body = {"name" => "John", "age" => 30}.to_json

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true # if making an HTTPS request
response = http.post(uri.path, body, headers)

puts response.body
355 chars
15 lines

In this example, we first require the necessary libraries: uri for parsing the request URL, net/http for making HTTP requests, and json for encoding our request body as JSON.

We then create a URI object for the endpoint that we want to hit, and define a hash of headers for our request. In this case, we set the Content-Type header to application/json.

We create our request body as a hash, and then use to_json to encode it as a JSON string. We then create a Net::HTTP object and use the post method to make our POST request with the URL path, request body, and headers as arguments.

Finally, we print out the response body.
