我一直在测试货件跟踪,我通过我的控制器获取信息。但是,当我在其他地方添加一行javascript代码时,跟踪始终返回未知。我不确定跟踪是否正确,并且总是返回未知或我的代码有问题。我存储了跟踪器ID,因此我总是可以在easypost上测试它。
这是订单状态未知的详细信息之一。

}

这是我的正常订单状态。

答案 0 :(得分:0)
即使提供了跟踪代码,USPS也不会立即开始跟踪。通常,您必须等到包裹进入邮件流之后才能看到任何有用的status
/ tracking_details
。
在您的情况下(在本文发布时),USPS也没有状态:https://tools.usps.com/go/TrackConfirmAction?tLabels=9470136897846111103191
