我使用OpenCPU创建了一个R API,用于查询neo4j数据库并返回结果。 结果看起来像
[ [
{
"abc": "aabbcc1",
"pqr": "ppqqrr1",
"xyz": "xxyyzz1"
}
],
[
{
"abc": "aabbcc2",
"pqr": "ppqqrr2",
"xyz": "xxyyzz2"
}
],
[
{
"abc": "aabbcc3",
"pqr": "ppqqrr3",
"xyz": "xxyyzz3"
}
]
]
这里有一个不必要的嵌套级别。我怎么摆脱这个? 我希望json看起来像
[
{
"abc": "aabbcc1",
"pqr": "ppqqrr1",
"xyz": "xxyyzz1"
},
{
"abc": "aabbcc2",
"pqr": "ppqqrr2",
"xyz": "xxyyzz2"
},
{
"abc": "aabbcc3",
"pqr": "ppqqrr3",
"xyz": "xxyyzz3"
}
]
我尝试在R控制台中打印结果,即在转换为JSON之前,它看起来像
[[1]]
abc pqr xyz
1 aabbcc1 ppqqrr1 xxyyzz1
[[2]]
abc pqr xyz
1 aabbcc2 ppqqrr2 xxyyzz2
[[3]]
abc pqr xyz
2 aabbcc3 ppqqrr3 xxyyzz3
我尝试使用此链接R How to remove a level of lists from a list of lists
中提到的解决方案之后生成的json看起来像
{"abc":["aabbcc1"],"pqr":["ppqqrr1"],"xyz":["xxyyzz1"],"abc.1":["aabbcc2"],"pqr.1":["ppqqrr2"],"xyz.1":["xxyyzz2"],"abc.2":["aabbcc3"],"pqr.2":["ppqqrr3"],"xyz.2":["xxyyzz3"]}

尝试将数据放入jsonlite::rbind.pages(yourdata)
,然后再将其投放到toJSON
。
