I am using an API where I supply an input string, and it returns some keyword autocompletions and product nodes.
My goal is to deserialize the response and get a list of the autocompletion Strings I can use. I'm trying implement this in an android application with the Retrofit library, which uses gson.
First off, I'm not sure the response I have is a typical JSON response. The 'nodes' item has key / value pairs, but the input string and the autocompletions list don't seem to have keys I can use.
["pol",
["polaroid camera",
"polo",
"polo ralph lauren",
"polo ralph lauren men",
"polar heart rate monitor",
"polaroid",
"polo shirt",
"polar watch",
"police scanner",
"polar"],
[{
"nodes": [{
"alias": "electronics",
"name": "Electronics"
},
{
"alias": "electronics-tradein",
"name": "Electronics Trade-In"
}]
},
{
},
{
},
{
},
{
},
{
},
{
},
{
},
{
},
{
}],
[]]
This is my attempt at the java classes for gson to deserialize to. However, it doesn't work as from what I understand, gson needs the class variables to match the JSON keys (true for Node class but not the rest).
class Response {
String input;
List<String> keywords;
List<Node> nodes;
}
class Node {
String alias;
String name;
}

the json only has a couple of keys in it, this is largely a Json Array.
if you can change the JSON, make it more like this
{
"input" : "pol",
"keywords" : ["polaroid camera","polo",...],
"nodes": [{
"alias": "electronics",
"name": "Electronics"
},
{
"alias": "electronics-tradein",
"name": "Electronics Trade-In"
}]
}
