Die Kreditkarte kann nicht mit Active Merchant validiert werden.

Question

Ich habe ein Problem mit der Validierung von Kreditkartendaten unter Verwendung des Active Merchant Gem. Wenn ich versuche, eine neue Zahlung einzugeben, habe ich immer den Fehler: The credit card you provided was declined. 2 Please double check your information and try again.. Dies bedeutet, dass die Antwort kein Erfolg ist. Ich habe keine Ahnung warum. Ich verwende Code aus Tutorial: Active Merchant Tutorial

payment.rb

class Payment < ActiveRecord::Base 
    require "active_merchant/billing/rails" 

attr_accessor :card_security_code 
attr_accessor :credit_card_number 
attr_accessor :expiration_month 
attr_accessor :expiration_year 

validates :first_name, presence: true 
validates :last_name, presence: true 
validates :card_security_code, presence: true 
validates :credit_card_number, presence: true 
validates :expiration_month, presence: true, numericality: { greater_than_or_equal_to: 1, less_than_or_equal_to: 12 } 
validates :expiration_year, presence: true 
validates :amount, presence: true, numericality: { greater_than: 0 } 

validate :valid_card 

def credit_card 
    ActiveMerchant::Billing::CreditCard.new(
    number:    credit_card_number, 
    verification_value: card_security_code, 
    month:    expiration_month, 
    year:    expiration_year, 
    first_name:   first_name, 
    last_name:   last_name 
    ) 
end 

def valid_card 
    if !credit_card.valid? 
    errors.add(:base, "The credit card information you provided is not valid. Please double check the information you provided and then try again.") 
    false 
    else 
    true 
    end 
end 

def process 
    if valid_card 
    response = GATEWAY.authorize(amount * 100, credit_card) 
    if response.success? 
     transaction = GATEWAY.capture(amount * 100, response.authorization) 
     if !transaction.success? 
     errors.add(:base, "The credit card you provided was declined. Please double check your information and try again.") and return 
     false 
     end 
     update_columns({authorization_code: transaction.authorization, success: true}) 
     true 
    else 
     errors.add(:base, "The credit card you provided was declined. 2 Please double check your information and try again.") and return 
     false 
    end 
    end 
end 
end 

initializers/activemerchant.rb

if Rails.env == "development" 
    #we set up a log file 
    ActiveMerchant::Billing::FirstdataE4Gateway.wiredump_device = File.open(Rails.root.join("log","active_merchant.log"), "a+") 
    # enable logging 
    ActiveMerchant::Billing::FirstdataE4Gateway.wiredump_device.sync = true 
    # we wish to use the test version of the gateway 
    ActiveMerchant::Billing::Base.mode = :test 

    login = ENV["GATEWAY_ID"] 
    password = ENV["GATEWAY_PASSWORD"] 
elsif Rails.env == "production" 
    login = ENV["GATEWAY_ID"] 
    password = ENV["GATEWAY_PASSWORD"] 
end 
GATEWAY = ActiveMerchant::Billing::FirstdataE4Gateway.new({ 
     login: login, 
     password: password 
}) 

gateway_id und GATEWAY_PASSWORD Daten, die ich in .env Datei speichern. Update: Wenn ich response.inspect verwenden, zeigt dies:

#<ActiveMerchant::Billing::Response:0x007f4d0bfc8d98 @params={"transaction_approved"=>"false", "error_number"=>"401", "error_description"=>"Unauthorized Request. Bad or missing credentials."}, @message="Unauthorized Request. Bad or missing credentials.", @success=false, @test=true, @authorization="", @fraud_review=nil, @error_code=nil, @avs_result={"code"=>nil, "message"=>nil, "street_match"=>nil, "postal_match"=>nil}, @cvv_result={"code"=>nil, "message"=>nil}> 

Answer 1

Unauthorized Request. Bad or missing credentials. 

Dies deutet darauf hin, dass vielleicht Ihre Login oder Passwort Variablen sind nicht richtig eingestellt werden? Haben Sie sichergestellt, dass die Umgebungsvariablen GATEWAY_ID und GATEWAY_PASSWORD in Entwicklungs- und Produktionsumgebungen richtig eingestellt sind?
