所以我尝试使用PayPal-Ruby-SDK更新卡片。我直接从示例here中获取了大部分代码。
要查找要更新的卡片：
@credit_card = CreditCard.find(user.card_id)
=>
#<PayPal::SDK::REST::DataTypes::CreditCard:0x007f954d8b9a68
@create_time="2015-12-22T00:58:40Z",
@error=nil,
@expire_month=10,
@expire_year=2017,
@id="CARD-8JN90741LM8220207KZ4KAQA",
@links=
[#<PayPal::SDK::REST::DataTypes::Links:0x007f954d89c990
@error=nil,
@href=
"https://api.sandbox.paypal.com/v1/vault/credit-cards/CARD-8JN90741LM8220207KZ4KAQA",
@method="GET",
@rel="self">,
#<PayPal::SDK::REST::DataTypes::Links:0x007f954d89c378
@error=nil,
@href=
"https://api.sandbox.paypal.com/v1/vault/credit-cards/CARD-8JN90741LM8220207KZ4KAQA",
@method="DELETE",
@rel="delete">,
#<PayPal::SDK::REST::DataTypes::Links:0x007f954d88bc08
@error=nil,
@href=
"https://api.sandbox.paypal.com/v1/vault/credit-cards/CARD-8JN90741LM8220207KZ4KAQA",
@method="PATCH",
@rel="patch">],
@number="xxxxxxxxxxxx3124",
@state="ok",
@type="discover",
@update_time="2015-12-22T00:58:40Z",
@valid_until="2018-12-21T00:00:00Z">
更新卡片......
@updated_card = {
:op=> "replace",
:path=> "/billing_address",
:value=> {
:line1=> "111 First Street",
:city=> "Saratoga",
:country_code=> "US",
:state=> "CA",
:postal_code=> "95070"
}
}
patch_request = Patch.new(@updated_card)
@credit_card.update(patch_request)
当我尝试使用这种方法时，它告诉我我使用了错误数量的参数...

我不太确定该错误是什么，因为文档告诉我必须传递更新的卡参数。它似乎是最新的，这是PayPal的文档推荐的软件包。
如果我尝试只使用没有参数的update（这没有多大意义），我会得到这样的答复：

我无法想到它会让我用0参数使用这个方法。我错过了一些明显的东西吗？
