How to send url-encoded form data using Faraday's post method?-CodePudding

I'm trying to setup Faraday to make requests to a Twilio API. I can make the requests via Postman setting up the key/values in the request body as x-www-form-urlencoded data.

When I try to replicate the cURL I make on Postman in Rails I get an error as if the key/value pairs I send in the payload are not recognized

The following cURL request works in Postman:

curl --location --request POST 'https://api.twilio.com/2010-04-01/Accounts/TOKEN1234/Messages.json' \
--header 'Authorization: Basic AUTH_TOKEN==' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'From=whatsapp: 5491112312312' \
--data-urlencode 'Body=Hello. Your order is on the way' \
--data-urlencode 'To=whatsapp: 541132132121'

My Faraday connector looks like this:

class Twilio::SubAccountConnector
  attr_reader :sid, :auth_token, :phone, :api_url

  def initialize(account)
    @sid = account.twilio_configuration.sid
    @auth_token = account.twilio_configuration.auth_token
    @phone = account.twilio_configuration.phone
    @api_url = "https://api.twilio.com/2010-04-01/Accounts/#{sid}/Messages.json"
  end

  def form_data
    {
      from: "whatsapp: 5491112312312",
      body: "Hello. Your order is on the way",
      to: "whatsapp: 541132132121",
    }
  end

  def send_whatsapp_notification
    connector.post do |req|
      req.body = form_data
    end
  end

  private

  def connector(url = api_url)
    Faraday.new(url: url) do |faraday|
      faraday.request :basic_auth, sid, auth_token
      faraday.request :url_encoded
      faraday.response :json
      faraday.adapter Faraday.default_adapter # make requests with Net::HTTP
    end
  end
end

This is the request body in the Faraday request:

request_body=
    "{\"From\":\"whatsapp: 5491112312312\",\"Body\":\"Hello. Your order is on the way\",\"To\":\"whatsapp: 541132132121\"}"

I'm getting the following error in the response body, so I suppose I'm doing something wrong with the way I'm sending the payload as the key/value pairs are not recognized.

response_body={"code"=>21604, "message"=>"A 'To' phone number is required.", "more_info"=>"https://www.twilio.com/docs/errors/21604", "status"=>400}>

Am I missing something in the connector method so the payload is encoded correctly?

CodePudding user response：

The issue is that the parameters should start with capital letters. Your Faraday request is otherwise correct, but your form_data method should look like:

  def form_data
    {
      From: "whatsapp: 5491112312312",
      Body: "Hello. Your order is on the way",
      To: "whatsapp: 541132132121",
    }
  end
