我使用以下参数使用快速结帐进行并行付款

`USER=<USR>' .
'&PWD=<PWD>' .
'&SIGNATURE=<SIGNATURE>' .
'&METHOD=SetExpressCheckout' .
'&RETURNURL=http://example.com/success.html' .
'&CANCELURL=http://example.com/canceled.html' .
'&VERSION=93' .
'&PAYMENTREQUEST_0_CURRENCYCODE=USD' .
'&PAYMENTREQUEST_0_AMT=250' .
'&PAYMENTREQUEST_0_ITEMAMT=225' .
'&PAYMENTREQUEST_0_TAXAMT=25' .
'&PAYMENTREQUEST_0_PAYMENTACTION=Sale' .
'&PAYMENTREQUEST_0_DESC=Product A' .
'&PAYMENTREQUEST_0_NAME=Product A' .            
'&PAYMENTREQUEST_0_SELLERPAYPALACCOUNTID=<SELLER1-PAYPALEMAIL>' .
'&PAYMENTREQUEST_0_PAYMENTREQUESTID=CART345-PAYMENT0' .

我期待着

'SELLER1 name
 Product A     225
 Tax 25
 SELLER2 name
 Extra Fee      65
 Total         325'

有人知道如何得到这个结果吗

谢谢

要在签出页面上显示行项目，必须传递行项目变量。它们以“L_u”开头

很有效，感谢我刚才按照建议添加了“L_u”参数。但还要注意，我必须添加所有参数L_PAYMENTREQUEST_0_NAME，L_PAYMENTREQUEST_0_NUMBER0 L_PAYMENTREQUEST_0_QTY0 L_PAYMENTREQUEST_0_TAXAMT0 L_PAYMENTREQUEST_0_AMT0 L_PAYMENTREQUEST_0_DESC0

'SELLER1 name 225 
Tax 25
SELLER2 name  65
Tax10        
Total         325'

'SELLER1 name
 Product A     225
 Tax 25
 SELLER2 name
 Extra Fee      65
 Total         325'
