firebase_firestore_parser.gd

### Use example
const PROJECT_ID := "<your project ID>"

const FIRESTORE_URL := "https://firestore.googleapis.com/v1/projects/%s/databases/(default)/documents/" % PROJECT_ID

func get_document(path: String) -> void:
	var url := FIRESTORE_URL + path
	http.request(url)

func _on_http_request_completed(result: int, response_code: int, headers: PoolStringArray, body: PoolByteArray) -> void:
	if body and JSON.parse(body.get_string_from_ascii()).result:
		var request_result := JSON.parse(body.get_string_from_ascii()).result as Dictionary
		var res = firebase_firestore_parse(request_result)


### Parser
func firebase_firestore_parse(firebase_firestore_json:Dictionary):
	var result:Dictionary
	if "fields" in firebase_firestore_json.keys():
		var fields:Dictionary = firebase_firestore_json["fields"]
		for key in fields.keys():
			result[key]=_firebase_firestore_parse(fields[key])
	return result

func _firebase_firestore_parse(value:Dictionary):
	var keys := value.keys()
	if keys.size()>0:
		var key = keys.front()
		if key == 'doubleValue':
			return float(value[key])
		elif key == 'integerValue':
			return int(value[key])
		elif key == 'arrayValue':
			var tmp_array:Array = value[key]["values"]
			var res_array:Array = []
			for value in tmp_array:
				res_array.push_back(_firebase_firestore_parse(value))
			return res_array
		elif key == 'mapValue':
			return firebase_firestore_parse(value[key])
		else:
			return value[key]
	return null
