Hi all,
Building off of a previous thread[1], I'm trying to parse a POST
request that contains JSON data. Specifically, I expect a JSON array
of JSON objects representing Packet model data and want to have a List
[Packet] at the end.
I am trying the following:
val packets = for {
JSONPackets <- req.param("packets")
packet <- JSONParser.parse(JSONPackets)
nodeId <- packet.param("node")
node <- nodeId.toLong
} yield {
val packet = Packet.create.node(node)
packet.save
packet
}
The problem is that JSONParser.parse returns a List[Any], so packet is
of type Any. I can try to convert packet to a Map with
packet.asInstanceOf[Map[String, String]], but this seems to just push
my type problems to the next line of code. I'm having a hard time
getting to the point where I have the Map[String, String] from which I
know I can extract values to create Packets, so I would appreciate
suggestions on how to do this.
This all seems quite complicated and I wonder if I'm missing an easier
way to do this. Is JSONParse the way to go, or should I switch to
Joni's lift-json stuff? I'm using 1.1-M5 but would be willing to
switch to 1.1-SNAPSHOT...
Thanks for your help.
