将具有相同键值的 Json 分组并使用 Jolt 重命名键

Question

这是 使用 Jolt 将具有相同键值的 Json 进行分组

中提出的问题的延续

我想使用 JOLT 对输出 JSON 进行以下更改。您能帮助获得所需的 JSON 输出吗？谢谢你。

• 为输出 json 中的每个对象添加“StartTime”
• 将 istance_3 和 distance_4 重命名为 X_Z_distance 和 Y_Z_distance
• 将 Temp_1 值四舍五入到小数点后 2 位

输入JSON：

Answer 1

您的初始 JOLT 规范未正确引用正确级别的 StartTime 字段。您试图在级别 * 访问它，但它应该在级别“0”。不包括将 distance_3 和 distance_4 分别重命名为 X_Z_distance 和 Y_Z_distance。

对 Temp_1 的修改不正确，并且您的 JOLT 规范缺少距离长度和距离类型的设置默认值。

我还删除了 distance_5，您的 JOLT 规范不包括删除所需输出中指定的 distance_5 键。

这是编辑后的 JOLT；
