【问题描述】：

我正在开发一个应用程序，用户 A 最多可以从不同的卖家那里购买 10 件商品，所以我需要同时向不同的用户汇款，我正在尝试使用 Paypal 链式付款。

现在我只是在玩经典 API（自适应支付），但我只是想知道为什么我总是收到这个错误：

 "The fee payer PRIMARYRECEIVER can only be used if a primary receiver is specified"

我已经指定了一个主要接收者，但我仍然收到该错误。

我找到了这些例子：https://paypal-sdk-samples.herokuapp.com/adaptive_payments/pay 我尝试进行连锁付款：

这是我的付款要求：

require 'paypal-sdk-adaptivepayments'
@api = PayPal::SDK::AdaptivePayments::API.new

# Build request object
@pay = @api.build_pay({
  :actionType => "PAY",
  :cancelUrl => "https://paypal-sdk-samples.herokuapp.com/adaptive_payments/pay",
  :currencyCode => "USD",
  :feesPayer => "PRIMARYRECEIVER",
  :ipnNotificationUrl => "https://paypal-sdk-samples.herokuapp.com/adaptive_payments/ipn_notify",
  :receiverList => {
    :receiver => [{
      :amount => 1.0,
      :email => "platfo_1255612361_per@gmail.com",
      :primary => true }] },
  :returnUrl => "https://paypal-sdk-samples.herokuapp.com/adaptive_payments/pay",
  :sender => {
    :useCredentials => true } })

# Make API call & get response
@pay_response = @api.pay(@pay)

这就是回应

{
  :responseEnvelope => {
    :timestamp => "2013-11-20T05:16:31-08:00",
    :ack => "Failure",
    :correlationId => "b002d0e27fd33",
    :build => "7935900" },
  :error => [{
    :errorId => 580023,
    :domain => "PLATFORM",
    :subdomain => "Application",
    :severity => "Error",
    :category => "Application",
    :message => "The fee payer PRIMARYRECEIVER can only be used if a primary receiver is specified",
    :parameter => [{
      :value => "feesPayer" },{
      :value => "PRIMARYRECEIVER" }] }] }

提前致谢！

【解决方案1】：

查看您的通话，您确实指定了主要接收方。但是，对于链式付款，您必须指定辅助接收方。

我刚刚使用以下参数进行了快速测试：

actionType = PAY  
requestEnvelope.errorLanguage = en_US  
cancelUrl = http://abortURL  
returnUrl = http://returnURL  
ipnNotificationUrl = http://ipnURL  
applicationId = Test  
memo = Test   
currencyCode = USD  
receiverList.receiver(0).email = test@test.com  
receiverList.receiver(0).amount = 5.00  
receiverList.receiver(0).primary = true  
feesPayer = PRIMARYRECEIVER

得到了结果：

responseEnvelope.timestamp=2013-11-20T05:41:56.751-08:00  
responseEnvelope.ack=Failure  
responseEnvelope.correlationId=b61a6b31ea2ab  
responseEnvelope.build=7935900  
error(0).errorId=580023  
error(0).domain=PLATFORM  
error(0).subdomain=Application  
error(0).severity=Error  
error(0).category=Application  
error(0).message=The fee payer PRIMARYRECEIVER can only be used if a primary receiver is specified  
error(0).parameter(0)=feesPayer  
error(0).parameter(1)=PRIMARYRECEIVER

但是，一旦我将 FeesPayer 更改为 EACHRECEIVER，我就会收到导致链式支付首先失败的错误消息：

responseEnvelope.timestamp=2013-11-20T05:48:09.202-08:00  
responseEnvelope.ack=Failure  
responseEnvelope.correlationId=987210ec4d03a  
responseEnvelope.build=7935900  
error(0).errorId=579008  
error(0).domain=PLATFORM  
error(0).subdomain=Application  
error(0).severity=Error  
error(0).category=Application  
error(0).message=You must specify only one primary receiver and at least one secondary receiver  
error(0).parameter(0)=1

我希望这会有所帮助。
