Rails ActiveMerchant - Paypal签出错误

Question

当我调用这个代码时，我会得到这个错误。

response = EXPRESS_GATEWAY.setup_purchase(order.price_in_cents,
  :ip                => request.remote_ip,
  :return_url        => url_for(:action => :create, :only_path => false),
  :cancel_return_url => root_path
)

redirect_to EXPRESS_GATEWAY.redirect_url_for(response.token)

错误：

This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow.

为了显示我正确地设置了EXPRESS_GATEWAY。代码development.rb文件。

config.after_initialize do
  ActiveMerchant::Billing::Base.mode = :test
  paypal_options = {
    :login => '*****************************',
    :password => '*************',
    :signature => '*******************************************************'
  }
  ::EXPRESS_GATEWAY = ActiveMerchant::Billing::PaypalExpressGateway.new(paypal_options)
end

创业板文件

gem 'activemerchant', :require => 'active_merchant'

所以登录密码和sig。是在paypal的沙箱中创建的。所以他们应该在工作。

我该怎么做才能修复这个错误呢？还是贝宝的一方？ActiveMerchant宝石有什么问题吗？

在检查了响应var之后，我得到的就是这个。

#<ActiveMerchant::Billing::PaypalExpressResponse:0x00000102402790 @params={"timestamp"=>"2012-06-29T01:30:18Z", "ack"=>"Failure", "correlation_id"=>"d1cb5dbb30425", "version"=>"72", "build"=>"3067390", "message"=>"CancelURL is invalid.", "error_codes"=>"10472", "Timestamp"=>"2012-06-29T01:30:18Z", "Ack"=>"Failure", "CorrelationID"=>"d1cb5dbb30425", "Errors"=>{"ShortMessage"=>"Transaction refused because of an invalid argument. See additional error messages for details.", "LongMessage"=>"CancelURL is invalid.", "ErrorCode"=>"10472", "SeverityCode"=>"Error"}, "Version"=>"72", "Build"=>"3067390"}, @message="CancelURL is invalid.", @success=false, @test=true, @authorization=nil, @fraud_review=false, @avs_result={"code"=>nil, "message"=>nil, "street_match"=>nil, "postal_match"=>nil}, @cvv_result={"code"=>nil, "message"=>nil}>

如有任何反馈，将不胜感激。

在查看了上面的消息之后，发现cancelURL是无效的，所以我修复了它并进行了预告！

谢谢。

当您没有正确登录到paypal站点上的沙箱帐户时，会显示此错误。

1. 登录到http://sandbox.paypal.com/
2. 打开您的站点并结帐
3. 当发送到paypal时，以买方测试帐户的身份登录
