Easypost 货件追踪问题

Question

我一直在测试货运跟踪，并通过我的控制器获取信息。然而，当我在其他地方添加一行 JavaScript 代码时，跟踪总是返回未知。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，这样我就可以随时在 EasyPost 上测试它。

这是订单的详细信息之一，状态未知。

{
  "id": "trk_884a31a503b745a7836c9fbed33212d5",
  "object": "Tracker",
  "mode": "test",
  "tracking_code": "9470136897846111103191",
  "status": "unknown",
  "status_detail": "unknown",
  "created_at": "2017-08-02T18:44:24Z",
  "updated_at": "2017-08-02T18:44:24Z",
  "signed_by": null,
  "weight": null,
  "est_delivery_date": null,
  "shipment_id": "shp_7bc893df86a94607b6d85a740a5ed3cb",
  "carrier": "USPS",
  "tracking_details": [],
  "fees": [],
  "carrier_detail": null,
  "public_url": "the url of the label"
}

这是我的一些正常订单状态。

Answer 1

即使提供了跟踪代码，USPS 也不会立即开始跟踪。一般来说，您必须等到包裹进入邮件流才能看到任何有用的

status

/

tracking_details

。

就您而言（在撰写本文时），USPS 也没有状态：https://tools.usps.com/go/TrackConfirmAction?tLabels=9470136897846111103191

Answer 2

如果您在使用快件追踪系统时发现状态显示“未知”，这可能是由于以下原因之一造成的：

• 确保您使用正确的跟踪代码。
• 仔细检查添加的 JavaScript 代码，确保正确处理跟踪号码。
• 快递公司可能尚未更新追踪信息。特别是在测试模式下，系统可能不会像真实环境中那样频繁更新。
• 使用已知的有效追踪号码进行测试。这可以帮助确认 该问题是否普遍存在或仅与特定问题相关 追踪号码。
• 使用浏览器的开发者工具查看网络请求并 应用程序发送的响应，这可以帮助识别 请求不正确。

如果问题仍然存在，请考虑更换API提供商或联系快递公司寻求更多帮助。
