从UPS收到奇怪的ZPL代码（如何解码此ZPL代码？）

Question

我使用UPS API发送“ ShipRequest”，并且我知道我们可以接收标签图像作为UPS的响应。

但是当我要求图像格式为'ZPL'时，它不是ZPL语言，而是未知语言，如下所示：

ZPL语言应如下所示： ^ XA ^ FO40，40 ^ GB300,203,8 ^ FS ... ...

那么，UPS的语言响应是什么？如何将这种未知语言解码为ZPL语言？

谢谢大家！

Answer 1

在大多数情况下，运营商网络服务会返回以base 64编码的ZPL代码。只需对其进行解码，您将获得UPS生成的实际ZPL代码。 （尝试使用https://www.base64decode.org/）

它看起来像这样：https://imgur.com/a/Ev5cTgE

Answer 2

将上述代码复制并粘贴到“base64decode”网址中。您将获得 ZPL 格式的标签字符串。

从 Base64 格式解码 https://www.base64decode.org/

然后复制字符串并粘贴到“labelary”网址中。重新绘制图像，您将看到示例标签打印。

http://labelary.com/viewer.html

上面提到的是手工作业。您可以使用 API 执行此操作。只需解码代码中的字符串并将 ZPL 字符串发送到以下 API。您将获得标签图像并将其发送到热敏打印机。先在邮递员那里查一下。

http://api.labelary.com/v1/printers/8dpmm/labels/4x6/0/

以下是执行以下操作后收到的示例图像：

1. 解码字符串
2. 将 zpl 字符串粘贴到“labelary”网址上。
