Paypal Transaction API Getting Total 不是一个有效的数值

【中文标题】Paypal Transaction API Getting Total 不是一个有效的数值

【英文标题】：Paypal Transaction API Getting Total is not a valid numeric value

【问题描述】：

我尝试了所有方法，但不知道为什么我不断收到错误消息“总计不是有效的数值”。一切都很好，直到我尝试为 $details 添加运费和税金。当我返回 $details 时，我得到这个 “shipping”：“49.99”，“tax”：“0.12”，“subtotal”：“50.81”。 $request 中的一切都很好，我只是不明白我做错了什么。似乎一切都加起来了，我并不总是得到错误。

【参考方案1】：

你有这段代码：

$details = new Details();
$details->setShipping($request->shipping_cost)
        ->setTax($request->tax)
        ->setSubtotal($total_price);

$amount = new Amount();
$amount->setCurrency("CAD")
       ->setTotal($details); //<--HERE

你看，你使用了Details 类的对象作为setTotal() 的值。我相信你需要用->setTotal($total_price);替换->setTotal($details);

【讨论】：

我在访问 api.paypal.com/v1/payments/payment 时收到 Got Http 响应代码 400。当我这样做时

那么现在是另一个错误吗？最后的总价格错误现在已修复？
