You have to submit the amount in your DoExpressCheckoutPayment API call as well as your SetExpressCheckout API call. Currently, you are not submitting the amount for both your SetEC and DoEC, only for your SetEC. (if you didn't set it for SetEC you would never have gotten a token.)
您必须提交您的DoExpressCheckoutPayment API调用的金额以及您的SetExpressCheckout API调用。目前，您没有提交SetEC和DoEC的数量，仅为您的SetEC提交。(如果你没有设置SetEC，你就不会得到一个令牌。)
Your DoEC call should be pretty much the same as your SetEC call except you don't need RETURNURL and CANCELURL.
您的DoEC调用应该与SetEC调用相同，只是不需要RETURNURL和CANCELURL。
Also, the amount will not show under order summary unless you submit the line item details for your transaction:
此外，除非您提交交易的行项明细，否则该金额将不会显示在订单摘要中:
L_PAYMENTREQUEST_0_NAME0=Books
L_PAYMENTREQUEST_0_AMT0=154.00
L_PAYMENTREQUEST_0_NUMBER0=ABC123
L_PAYMENTREQUEST_0_QTY0=2
L_PAYMENTREQUEST_0_NAME1=CDs
