我正在尝试使用Paypal的PHP api中的SetExpressCheckout调用来测试“Pay without Paypal Account”，但我指向的Paypal页面只能选择使用帐户付款或创建帐户 - 如果没有帐户，则无法支付费用。
我已经使用以下说明配置了我正在测试的沙盒卖家帐户，不要求用户拥有帐户：https://www.paypal-community.com/t5/Merchant-services-Archive/Paypal-account-optional/td-p/233270
在我调用$ paypalService-＆gt; SetExpressCheckout（）方法之前，这是setECReq对象的打印输出：
