Question

我一直在关注本教程

http://railscasts.com/episodes/146-paypal-express-checkout?autoplay=true

我已将paypal按钮放入购物车页面

<%= link_to(image_tag("https://www.paypal.com/en_US/i/btn/btn_xpressCheckout.gif"), express_checkout_path) %>

我的快速结账方法如下

def express_checkout
  response = EXPRESS_GATEWAY.setup_purchase(1000,

    ip: request.remote_ip,
    return_url: cart_item_index_path,
    cancel_return_url: cart_item_index_path,
    currency: "USD",
    allow_guest_checkout: true,
    items: [{name: "Order", description: "Order description", quantity: 1, amount: 1000}]

  )

  puts "printing token #{response.token}"


  redirect_to EXPRESS_GATEWAY.redirect_url_for(response.token)
end

当我打印response.token然后它打印空字符串。此外，当我运行应用程序并单击paypal按钮然后它重定向到

https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=

出现以下错误

没有令牌传递

我在rails中使用activemerchant gem。

确定。 byebug救了那一天。

我检查了响应对象中的错误，发现返回url和取消url是无效路径。

所以我改变了

response = EXPRESS_GATEWAY.setup_purchase(1000,

    ip: request.remote_ip,
    return_url: cart_item_index_path,
    cancel_return_url: cart_item_index_path,
    currency: "USD",
    allow_guest_checkout: true,
    items: [{name: "Order", description: "Order description", quantity: 1, amount: 1000}]

  )

到

response = EXPRESS_GATEWAY.setup_purchase(1000,

    ip: request.remote_ip,
    return_url: cart_item_index_url,
    cancel_return_url: cart_item_index_url,
    currency: "USD",
    allow_guest_checkout: true,
    items: [{name: "Order", description: "Order description", quantity: 1, amount: 1000}]

  )

它有效！谢谢byebug！
