FedEx-Rates API-计件数无效

Question

我试图获取两个地点之间包裹的运费。 在请求数组中，我创建了适当的结构，并在适当的位置提供了NumberOfPieces。

stdClass Object
(
    //OTHER ELEMENTS REDACTED HERE
    [RequestedShipment] => stdClass Object
    (
         [Commodities] => Array
                    (
                        [NumberOfPieces] => 1
                        [Description] => Dog Meat
                        [CountryOfManufacture] => US
                        [Weight] => Array
                            (
                                [Units] => LB
                                [Value] => 20
                            )

                        [Quantity] => 1
                        [QuantityUnits] => EA
                        [UnitPrice] => Array
                            (
                                [Currency] => USD
                                [Amount] => 20
                            )

                        [CustomsValue] => Array
                            (
                                [Currency] => USD
                                [Amount] => 100
                            )

                    )

现在的问题是，API的响应表明我输入的计件数无效。

stdClass Object
(
    [HighestSeverity] => ERROR
    [Notifications] => stdClass Object
        (
            [Severity] => ERROR
            [Source] => crs
            [Code] => 546
            [Message] => Invalid piece count. 
            [LocalizedMessage] => Invalid piece count. 
        )

    [Version] => stdClass Object
        (
            [ServiceId] => crs
            [Major] => 16
            [Intermediate] => 0
            [Minor] => 0
        )

)

我曾尝试在网上搜寻可能的解决方案，但徒劳无功。有帮助吗？

今天最终面对同样的问题。发货结构需要在RequestedShipment内部定义发货人和收件人。以下内容使我能够成功获得费率：

Array
(
    [WebAuthenticationDetail] => Array(...)
    [ClientDetail] => Array(...)
    [Version] => Array(...)
    [RequestedShipment] => Array
        (
            [Shipper] => Array(...)
            [Recipient] => Array(...)
            [PackageCount] => 1
            [RequestedPackageLineItems] => Array(...)
        )
)
