I am sending myself JSON like so with jQuery:
$.ajax
({
type: "POST",
url: 'http://localhost:8080/myproject/myController/myAction',
dataType: 'json',
async: false,
//json object to sent to the authentication url
data: {"stuff":"yes",
"listThing":[1,2,3],
"listObjects":[{"one":"thing"},{"two":"thing2"}]},
success: function () {
alert("Thanks!");
}
})
I send this to a controller and do
println params
And I know I'm already in trouble...
[stuff:yes, listObjects[1][two]:thing2, listObjects[0][one]:thing, listThing[]:[1, 2, 3], action:myAction, controller:myController]
I cannot figure out how to get at most of these values...
I can get "yes" with params.stuff, but I cant do params.listThing.each{} or params.listObjects.each{}
What am I doing wrong?
UPDATE:
I make the controller do this to try the two suggestions so far:
println params
println params.stuff
println params.list('listObjects')
println params.listThing
def thisWontWork = JSON.parse(params.listThing)
render("omg l2json")
look how weird the parameters look at the end of the null pointer exception when I try the answers:
[stuff:yes, listObjects[1][two]:thing2, listObjects[0][one]:thing, listThing[]:[1, 2, 3], action:l2json, controller:rateAPI]
yes
[]
null

stuff: yes
listObjects[1][two]: thing2
listObjects[0][one]: thing
listThing[]: 1
listThing[]: 2
listThing[]: 3
UPDATE 2 I am learning things, but this can't be right:
println params['listThing[]']
println params['listObjects[0][one]']
prints
[1, 2, 3]
thing
It seems like this is some part of grails new JSON marshaling. This is somewhat inconvenient for my purposes of hacking around with the values. How would I get all these individual params back into a big groovy object of nested maps and lists?
Maybe I am not doing what I want with jQuery?
