POST request using CURL for Rails application

This question is asked by many users and I tried all solutions but none of them worked. for ex: this question is here curl json post request via terminal for rails app , but still the same result.

I am trying to POST data through the terminal using CURL by running the following command:

curl -i -H 'Authorization: Token token'="9asdadsasd87t8ddaghsd" -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"request":{"sender_mobile":"12331212","recipient_mobile":"121231231","location":"Bangalore"}}'  http://localhost:3000/api/v1/requests

      

        
        
        
      

    

and Getting a response:

HTTP/1.1 422 Unprocessable Entity 
Content-Type: text/html; charset=utf-8
Content-Length: 15450

with so many lines of garbage, but I think this answer is enough to understand what might be causing it. Here is a link to the complete error http://pastebin.com/n342HeYL

I can successfully complete a GET request with the command:

curl -i 'http://localhost:3000/api/v1/requests' -H 'Authorization: Token token'="952aa4598ec2cd87c8b69056616a00af"

So, I don't know what happened to the POST request.

Here is my request_controller.rb file

module Api
  module V1
    class RequestsController < ApplicationController
      # skip_before_action :verify_authenticity_token
      before_filter :restrict_access

      respond_to :json

      def index
        respond_with Request.all
      end

      def show
        respond_with Request.find(params[:id])
      end

      def create
        respond_with Request.create(params[:request])
      end

      def update
        respond_with Request.update(params[:id], params[:request])
      end

      def destroy
        respond_with Request.destroy(params[:id])
      end

      private

      def restrict_access
        authenticate_or_request_with_http_token do |token, options|
          ApiKey.exists?(access_token: token)
        end
      end
    end
  end
end
