金额与PaypalExpressGateway.setup_authorization匹配的问题

Question

我正在使用带有activemerchant的 ruby 客户端来创建对PayPal沙盒 API 的调用。脚本是从命令行调用的，因此变量填充了命令行参数。下面是代码示例：

login = ARGV[0]
password = ARGV[1]
signature = ARGV[2]
ip = ARGV[3]
subtotal = ARGV[4]
shipping = ARGV[5]
handling = ARGV[6]
tax = ARGV[7]
currency = ARGV[8]
return_url = ARGV[9]
cancel_return_url = ARGV[10]
allow_guest_checkout = ARGV[11]
items = JSON.parse(ARGV[12])
ActiveMerchant::Billing::Base.mode = :test
paypal_options = {
    login: login,
    password: password,
    signature: signature
}
gateway = ActiveMerchant::Billing::PaypalExpressGateway.new(paypal_options)
setup_hash = {
    ip: ip, 
    items: items, 
    subtotal: Integer(subtotal),
    shipping: Integer(shipping),
    handling: Integer(handling), 
    tax: Integer(tax), 
    currency: currency, 
    return_url: return_url, 
    cancel_return_url: cancel_return_url, 
    allow_guest_checkout: allow_guest_checkout
}
amount = subtotal.to_i + shipping.to_i + handling.to_i + tax.to_i
puts "amount: " + amount.to_s
puts "items: " + items.to_s
response = gateway.setup_authorization(amount, setup_hash)
if !(response.success?)
    puts response.message.to_s
end

这是我在控制台中得到的：

amount: 10000
items: [{"name"=>"sample", "description"=>"desc", "quantity"=>1, "amount"=>10000}]
The totals of the cart item amounts do not match order amounts.

那么，为什么 10000

的数量与 10000 的项目不匹配呢？

Answer 1

经过漫长而无聊的调试，我发现了以下内容：在上面的示例中，内部哈希items应该是[:{name=>"sample", :description=>"desc", :quantity=>1, :amount=>10000}]的，而不是[{"name"=>"sample", "description"=>"desc", "quantity"=>1, "amount"=>10000}]的。

因此，我将 JSON 解析器更改为 nice_hash 并且items = ARGV[12].json它就像一个魅力。
