我真的需要您的帮助!我有一个看起来像这样的.JSON文件:
{
"_id" : { "$yid" : "279e128r" },
"userId" : "245981e3",
"data" : {
"workRate" : 51,
"workStages" : [
{ "quantity" : 33, "value" : "APPLES" },
{ "quantity" : 32, "value" : "PEACH" },
{ "quantity" : 12, "value" : "AVOCADO" },
{ "quantity" : 53, "value" : "APPLES" },
{ "quantity" : 22, "value" : "PEACH" },
{ "quantity" : 27, "value" : "AVOCADO" }
],
"timeInterval" : 25,
"timeSource" : 1
},
"sessionStartTime" : 1494311320,
"sessionEndTime" : 1494336640
}
大约有500位ID(“ _ id”),有30位参与者(“ userId”)。
因此,我想获取现有的JSON数据,并创建一个仅包含30个对象(每个参与者的每个对象)的新数组,然后找到“数据”字段并计算提及蔬菜的次数,然后合并它们,并具有被提及的次数。
{
"userId" : "245981e3",
"data" : {
"workRate" : 51,
"workStages" : [
{ "value" : "APPLES", "times": 2 },
{ "value" : "PEACH", "times": 2 },
{ "value" : "AVOCADO", "times": 2 }
]
}
}
{
"userId" : "7295ew41",
"data" : {
"workRate" : 45,
"workStages" : [
{ "value" : "LEMON", "times": 13 },
{ "value" : "AVOCADO", "times": 42 },
{ "value" : "KIWI", "times": 14 }
]
}
}
我知道这听起来很困难,但是我相信有人可以帮助我!
