在R中使用jsonlite时，如何手动指定哪些被视为数组？在这种情况下 auto_unbox 不起作用

问题描述

我有以下代码：

data = list(
    "id" = equip_id,"initial_date" = 1608433200,"final_date" = 1609038000,"limit" = 10000,"order" = "asc","properties" = "forecast"
)

如果我使用：

jsonlite::toJSON(data,auto_unBox = TRUE)

我有这个：

{"id":3,"initial_date":1608433200,"final_date":1609038000,"limit":10000,"order":"asc","properties":"forecast"} 

但我想要的是：

{"id":3,"properties":["forecast"]} 

如何手动编辑哪些是数组？

解决方法

将 properties 转换为列表：

data = list(
    "id" = equip_id,"initial_date" = 1608433200,"final_date" = 1609038000,"limit" = 10000,"order" = "asc","properties" = list("forecast")
)
