不知道这是否可行或者我是否必须执行额外的步骤，但是有没有办法导出到没有主方括号的 json 文件：

[
    {
        "Name":"John",
        "Phone":"123-456-7890"
    }
]

留下类似这样的内容：

{
    "Name":"John",
    "Phone":"123-456-7890"
}

这是我所得到最接近的答案：

df <- data.frame (
  Name = c("John"),
  Phone = c("123-456-7890")
)
jsonlite::write_json(df,'test.json',pretty = TRUE)

如何在 Julia 中加入字典，类似于 Python 的一种方式：

 diction = {"DC": 4,
           "NH": 1,
           "MI": 36,
           "MO": 4989,
           "FL": 157,
           "UT": 13,
           "NV": 9,
           "CA": 110,
           "WV": 6,
           "NY": 39,
           "ME": 1,
           "SC": 26,
           "KY": 71}
stri = ' | '.join(map(lambda x: '%2.2s %5.5s' % (str(x[0]), str(x[1])), diction.items()))

我想出了什么：

diction = Dict(["DC" => 4
                "NH" => 1,
                "MI" => 36,
                "MO" => 4989,
                "FL" => 157,
                "UT" => 13,
                "NV" => 9,
                "CA" => 110,
                "WV" => 6,
                "NY" => 39,
                "ME" => 1,
                "SC" => 26,
                "KY" => 71])
stri = [@sprintf("%2.2s %5.5s | ",st,ct) for st,ct in keys(diction),values(diction)]

产量：

ERROR: syntax: invalid iteration specification

输出：

DC    4 | NH    1 | MI    36 | MO    4989 | FL    157 | UT    13 | NV    9 | CA    110 | WV    6 | NY    39 | ME    1 | SC    26 | KY    71
