如何处理USPS集成中的异常情况？

Question

当出现USPS异常时，填充什么消息？API名称是跟踪和交付信息。。

我已经成功地在我的机器上集成了USPS。我能够获得产品状态的跟踪号码，但可能有条件，当异常可能发生在API，我想管理警报的条件，以便我可以被告知的情况下。我想知道怎样才能检测到异常？

Answer 1

我使用了EasyPost API来获得更详细的跟踪和传递信息？可能会有帮助吗？我发现USPS异常通知不太有用。

否则，您可以设置异常通知服务，以便在发生API异常时通知您。

Answer 2

我注意到还有另一种形式的API，您可以在响应中获得更多的信息。在" XML“查询字符串参数中传递此XML文档：

<TrackFieldRequest USERID="XXXXXXXX">
  <Revision>1</Revision>
  <ClientIp>x.x.x.x</ClientIp>
  <SourceId>customer / company name</SourceId>
  <TrackID ID="9102xxxxxxxxx"></TrackID>
</TrackFieldRequest>

这个XML文档的响应如下所示：

<TrackResponse>
  <TrackInfo ID="9102xxxxxx">
