I have some response data in JSON format:
{ "items" :
[
{"commentId" : "28444760","userId" : "142607","userIP" : "","userName" : "Rock'n'Roll ","userAvatar" : "/i/default_userpic.png ","userIsBlock" : false,"userBanDate" : "",
"userCountry" : "http://ikor.ill.in.ua/f/UA.gif","date" : "16.02.2017, 17:07","text" : "txt","rate" : 2,"isLikeExist" : false,"childComments" : []}
]
}
and I want to parse it to lists. For example, to extract commentId
I use:
val js = parse(json)\\"items"
val commentId:List[String] = js\\"commentId"\ classOf[JString]
and I get list with id
when I tried parsing date
I got:
List(16.02.2017, 17:24, 16.02.2017, 17:23)
How I can return the date list in the format List("date time")?
This is how you can parse date/times with a format specification:
def parseDT(s: String) = {
val fmt = "dd.MM.yyyy, HH:mm"
val df = java.time.format.DateTimeFormatter.ofPattern(fmt)
java.time.LocalDateTime.parse(s, df)
}
So after you get the dates from JSON (as strings) parse them: val dates = datesFromJSON.map(parse(_))
If all you want is to remove the comma from the date strings, you can do val dates = datesFromJSON.map(s => s.replaceAll(",",""))
The solution in my case is:
val dateFormat = new SimpleDateFormat("dd.MM.yyyy, HH:MM")
val date:List[java.util.Date] = (js\\"date").children.map(x=>dateFormat.parse(x.values.toString))
