購物車項目總金額與訂單金額不匹配

Question

我已閱讀了關於同一主題的其他帖子，但我非常肯定我沒有對這些帖子的問題產生任何影響。這真讓我很沮喪，所以任何幫助或建議，將不勝感激。

我正在建立以下數組以便在SetExpressCheckout調用中發送，但在每次提交時，我都會得到「購物車項目總數與訂單數量不匹配」，但我不明白如何！

[METHOD] => SetExpressCheckout 
[USER] => myusername 
[PWD] => 1398341028 
[SIGNATURE] => xxxsignaturexxx 
[VERSION] => 85.0 
[RETURNURL] => http://www.mysite.dev/payment/process 
[CANCELURL] => http://www.mysite.dev/payment/cancelled 
[PAYMENTREQUEST_0_PAYMENTACTION] => SALE 
[NOSHIPPING] => 0 
[PAYMENTREQUEST_0_AMT] => 189.00 
[PAYMENTREQUEST_0_ITEMAMT] => 189.00 
[PAYMENTREQUEST_0_TAXAMT] => 0 
[PAYMENTREQUEST_0_SHIPPINGAMT] => 0 
[PAYMENTREQUEST_0_HANDLINGAMT] => 0 
[PAYMENTREQUEST_0_SHIPDISCAMT] => 0 
[PAYMENTREQUEST_0_INSURANCEAMT] => 0 
[PAYMENTREQUEST_0_CURRENCYCODE] => GBP 
[LOCALECODE] => GB 
[ALLOWNOTE] => 1 
[L_PAYMENTREQUEST_0_NAME0] => Website Order 
[L_PAYMENTREQUEST_0_NUMBER0] => 28424747 
[L_PAYMENTREQUEST_0_AMT0] => 189.00 
[L_PAYMENTREQUEST_0_QTY0] => 1 

很多感謝您的閱讀。 Kris

我繼續前進，並使用測試帳戶測試了您的呼叫，最初它給出了與您所描述的類似的錯誤。我確實得到它與我作爲呼叫的格式和間隔的唯一修改一起工作。

這是我提交，並得到了成功響應號召，注意：我確實有更改用戶，PWD，簽名，版本，returnrul和cancelurl能夠測試：
