Sending JSON/Array Object to backend

[leifg]

Hello everyone,

I try to send a a serlialized array using the jQuery method
serializeArray(). Afterwards I send an Ajax "PUT" request to the
according URL.

like this:

var data = $("#createForm").serializeArray();
$.ajax({
type: "PUT",
url: "http://localhost:9000/leifg",
data: data
});

I can debug in the backend method public static void createJson(String
screenName, String data), but the String variable data is null.

If I change the signature to public static void createJson(String
screenName, HashMap<String, String> data), I will just get an empty
HashMap.

In the debug mode, I can see, that there is a HashMap inside the
params variable called "data" which contains all the data from the
form.

My question now is:
- how can I access this Hashmap (params.get("data", HashMap.class);
didn't work)?
- is there a better way to deal with JSON/String-Arrays in the play!
backend?

Can you show me what the data Javascript object looks like?

OK so the frontend delivers an object array (i made a screenshot,
since i found no easy way to dump the data into a single string):

In the java backend I get the variable data, which is a HashMap and
looks something like this:

{body=[Ljava.lang.String;@31133976,
tweetSpanEnd=[Ljava.lang.String;@65218b25,
queueType=[Ljava.lang.String;@7d365e01,
screenName=[Ljava.lang.String;@78189538,
queueName=[Ljava.lang.String;@7c55d3df,
queueDescription=[Ljava.lang.String;@66c9153e,
tweetSpanStart=[Ljava.lang.String;@1b91ce2a,
queueInterval=[Ljava.lang.String;@176358a,
tweetSpanEnabled=[Ljava.lang.String;@77b4f7c5}

Ok so it is very complicated to have this stuff bound automatically.

My advice:

public static void yop(String body) {
// here body contains the json string
// use GSON to parse it dynamically
