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

Question

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,"initial_date":1608433200,"final_date":1609038000,"limit":10000,"order":"asc","properties":["forecast"]}

如何手动编辑哪些是数组，哪些不是？

Answer 1

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")
)

When using jsonlite in R, how to specify manually which are treated as arrays? The auto_unbox doesn't work in this case

r

json

jsonlite
