当我尝试通过贝宝沙箱提交测试付款时，我收到了以下新回复：
array(2) { ["header"]=> string(287) "HTTP/1.1 400 Bad Request Server: Apache-Coyote/1.1 PayPal-Debug-Id: b235ca4e7c1ed Content-Type: application/json Content-Length: 334 DC: origin1-api.sandbox.paypal.com Date: Thu, 10 Oct 2013 17:23:54 GMT Connection: close Set-Cookie: DC=origin1-api.sandbox.paypal.com; secure " ["body"]=> object(stdClass)#4 (5) { ["name"]=> string(16) "VALIDATION_ERROR" ["details"]=> array(1) { [0]=> object(stdClass)#5 (2) { ["field"]=> string(12) "transactions" ["issue"]=> string(95) "Item amount must add up to specified amount subtotal (or total if amount details not specified)" } } ["message"]=> string(29) "Invalid request - see details" ["information_link"]=> string(73) "https://developer.paypal.com/webapps/developer/docs/api/#VALIDATION_ERROR" ["debug_id"]=> string(13) "b235ca4e7c1ed" } }
这个错误表明我的项目总数没有加到我的小计中，但很明显，正如您从下面的 json 中看到的那样：

这是我的贝宝代码：
