swift vapor json response to array - arrays

Question

using swift vapor and elasticsearch, got a response like:
{
"_shards": {
"failed": 0,
"successful": 5,
"total": 5
},
"hits": {
"hits": [
{
"_id": "3",
"_index": "items_v1",
"_score": 1.2029922,
"_source": {
"property1": "test",
"property2": "another test",
...
},
"_type": "item"
},
...
inside "hits" -> "hits" -> "_source" I got all the properties of my model "Item". How can I create an array of Items "[Item]" from this json response?

Answer 1

Small enhancement, use a guard statement to avoid the nested ifs...
guard
let dict = response as? [String : Any],
let hits = dict["hits"] as? [String : Any],
let hitArray = hits["hits"] as? [[String : Any]]
else
{ throw Abort}
for hit in hitArray {
if let source = hit["_source"] {
arrayOfItems.append(Item(with: source))
}
}

Answer 2

Parse your response in this way, so there will be no crashes if some value will not be sent.
if let dict = response as? [String : Any] {
if let hits = dict["hits"] as? [String : Any] {
if let hitArray = hits["hits"] as? [[String : Any]] {
for hit in hitArray {
if let source = hit["_source"] {
arrayOfItems.append(Item(with: source))
}
}
}
}
}
Int your Item class create init method, where you will initialize item's properties.
init(with dict: [String : Any]) {
if let property1 = dict["property1"] as? Int {
self.property1 = property1
}
super.init()
}

Try like this! I assume that you get the Response and that response in saved in response variable
var myarray = [String]()
let hitDict = response["hits"] as! [String:AnyObject]
let hitArray = hitDict["hits"] as! Array
let someDict = hitArray[0] as! [String:AnyObject]
let sourcDict = someDict["_source"] as! [String:AnyObject]
let property1 = sourcDict["property1"] as! String
let property2 = sourcDict["property2"] as! String
myarray.append(property1)
myarray.append(property2)

var myArray = [String:String]()
//response from try drop.client.get(…)
let bodyReceived = responseFirebaseAssigned?.body.bytes
//JSON object made of bodyReceived
let JsonFirebase:JSON?
for val in JsonFirebase?.object ?? [:]{
let valKey = val.key.string
let valValue = val.value.string
arrayFB[valKey!] = valValue
print("arrayFB is \(arrayFB)")
}
