Error to parse from alomofire post request - ios

Question

I have an issue with parsing using alamofire. I get an error to try to decode the json file that i get in return from the request.
I have tried to parse JSON file that looks like this:
success({
data = {
id = "eb259a9e-1b71-4df3-9d2a-6aa797a147f6";
nickname = joeDoe;
options = {
avatar = avatar1;
};
rooms = "<null>";
};
})
It Gives me an error that looks like this:
keyNotFound(CodingKeys(stringValue: "id", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"id\", intValue: nil) (\"id\").", underlyingError: nil))
The user model looks like this:
import Foundation
struct userModel: Codable {
let id: String
let nickname: String
let options: options
let rooms: String
enum CodingKeys: String, CodingKey {
case id = "id"
case nickname = "nickname"
case options = "options"
case rooms = "rooms"
}
}
struct options: Codable {
var avatar: String?
enum CodingKeys: String, CodingKey {
case avatar = "avatar"
}
}
And the function looks like this:
func postUser(){
AF.request("http://test.com/", method: .post, parameters: user).responseJSON {response in
guard let itemsData = response.data else {
print("test1")
return
}
do {
print("hallo!")
let decoder = JSONDecoder()
print("")
print(itemsData)
print("")
print(response.description)
let items = try decoder.decode(userModel.self, from: itemsData)
print(items)
DispatchQueue.main.async {
print("test2")
}
} catch {
print(error)
print("test3")
}
}
How do i fix the issue?

Answer 1

You are ignoring the root object, the dictionary with key data.
Create another struct
struct Root : Decodable {
let data : UserModel
}
And please name structs with starting capital letter and you don't need the CodingKeys if the struct member names match the keys
struct UserModel: Codable {
let id: String
let nickname: String
let options: Options
let rooms: String
struct Options: Codable {
var avatar: String?
}
Then decode
let result = try decoder.decode(Root.self, from: itemsData)
let items = result.data
Consider that AF can decode JSON with JSONDecoder implicitly.
