信用卡验证不适用于 Braintree 和 rails

Question

我在创建客户时尝试使用 Braintree api 进行卡片验证。这是创建客户的代码：

@braintree_id = "#{current_user.profile_name}" + rand(5..1000).to_s
@result = Braintree::Customer.create(
    :id => @braintree_id,
    :first_name => employer_account_params[:first_name],
    :last_name => employer_account_params[:last_name],
    :company => employer_account_params[:company],
    :email => employer_account_params[:email],
    :phone => employer_account_params[:phone],
    :fax => employer_account_params[:fax],
    :website => employer_account_params[:website],
    :credit_card => {
        :number => employer_account_params[:credit_card][:number],
        :expiration_date => employer_account_params[:credit_card][:expiration_date],
        :billing_address => {
          :street_address => employer_account_params[:credit_card][:billing_address][:street_address],
          :extended_address => employer_account_params[:credit_card][:billing_address][:extended_address],
          :locality => employer_account_params[:credit_card][:billing_address][:locality],
          :region => employer_account_params[:credit_card][:billing_address][:region],
          :postal_code => employer_account_params[:credit_card][:billing_address][:postal_code],
          :country_code_alpha2 => employer_account_params[:credit_card][:billing_address][:country_code_alpha2]
        },
        :options => {
            :verify_card => true
            }
    }
)
puts 'result is ' + @result.inspect.to_s
@verification = @result.credit_card_verification
puts 'verification' + @verification.inspect.to_s
puts 'card results: ' + @verification.gateway_rejection_reason.to_s

问题在于 credit_card_verification 始终为零，无论 @result 返回 true 还是 false。这是上面代码中的控制台日志：

如何才能使验证有效？

Answer 1

Braintree 只会在传入的参数有效的情况下运行验证，如果失败则只返回验证。

在您的第一个示例（现在从您的帖子中删除）中，创建失败，因为您没有传递有效的参数。

在您的第二个示例中，验证成功，因此不会返回。

您可以使用无效的卡号或Sandbox credit card numbers or unsuccessful verification numbers 之一在沙盒中模拟这些不同的情况。

例子：

result = Braintree::Customer.create(  
  :credit_card => {                   
    :number => "4000111111111115",    
    :expiration_month => "10",        
    :expiration_year => "2014",       
    :cvv => "200",                    
    :options => {:verify_card => true}
  }                                   
)                                     

if result.success?
  # handle success
elsif result.credit_card_verification
  p verification.processor_response_code
  p verification.processor_response_text
else
  # use result.errors to see what part of the request was invalid
