USPS运输计算器API未返回有效响应 - USPS shipping calculator API not returning valid response

USPS shipping calculator API not returning valid response

我从USPS得到这个错误我正在查询http://production.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=

<Error>
    <Number>80040b1a</Number>
    <Description>Authorization failure.  You are not authorized to connect to this server.</Description>
    <Source>UspsCom::DoAuth</Source>
</Error>

如果我在测试服务器http://production.shippingapis.com/ShippingAPItest.dll?API=RateV4&XML=上进行相同的查询，它会得到以下错误

<Error>
    <Number>80040b1a</Number>
    <Description>API Authorization failure. RateV4 is not a valid API name for this protocol.</Description>
    <Source>UspsCom::DoAuth</Source>
</Error>

Ravish- RateV4不适用于测试服务器，因此您将无法获得任何响应。并且，关于生产服务器中的RateV4，您需要获得ICCC, USPS的许可。希望能有所帮助。
