Android Convert Firebase Cloud Function Reponse (HttpsCallableResult) to Json or Class Object/POJO
October 11, 2019NOTE:
- Using
org.json.JSONObject
to convert Map to json string - Using Kotlin Serialization to convert json string to class object/pojo
- I believe
Gson
could be used to achieve the above as well
@Serializable
class Person(val name: String, @SerialName("nick_name") val nickName: String, val age: Int, val friends: List<String>)
fun getPersonFunction(): Task<Person> {
val functions = FirebaseFunctions.getInstance()
val data = mapOf(
"name" to "Desmond"
)
return functions.getHttpsCallable("get_person")
.call(data)
.continueWith { task ->
@Suppress("UNCHECKED_CAST")
val result = task.result?.data as Map<String, Any>
// convert data to json string
val jsonString = JSONObject(result).toString()
// convert Json string to Person
val json = Json(JsonConfiguration.Stable.copy(strictMode = false))
json.parse(Person.serializer(), jsonString)
}
}
