How to make a Faraday post request?

In Rails, Faraday is a popular HTTP client library that allows you to send HTTP requests from your Rails application to external APIs. To send a POST request using Faraday, you can follow these steps:

1. First, make sure you have the Faraday gem installed by adding it to your Gemfile and running bundle install:

gem 'faraday'

Next, create a new instance of Faraday with the URL of the API you want to send the POST request to:

require 'faraday'

Some cases we may need to add require for the faraday package.

IMPORTANT

@@conn = Faraday.new(
  url: 'http://127.0.0.1:3000',
  headers: {'Accept' => '*/*'})

We can pass any header values and parameters here. If you are calling multiple times with different data to the same URL then you can add the connection object variable as a class variable(like “@@var”), then we can make a request like this:

def createdata
    head :no_content
    form_data={first_name: params[:first_name], last_name: params[:last_name], email: params[:email],user_name: params[:username]}
    response = @@conn.post("/user", form_data,"content_type"=>"application/json")
    print("here #{response.body}") 

  end

I have added it inside my “createdata” method, so when the route hits it will execute.
