无法将 JSON 响应添加到领域

Question

我正在尝试将我的 POST 响应添加到领域，但我抛出了这个错误：

无法将“字符串”类型的值转换为预期的参数类型“对象”

这是我的代码：

     Alamofire.request(.POST, Data.loginEndpoint, parameters: parameters)
        .responseObject { (response: Response<Particulars, NSError>) in

            print(response.request)
            print(response.response)
            print(response.result)


            if let result = response.result.value
            {

                do{
                    print(Realm.Configuration.defaultConfiguration.fileURL)
                    let realm = try Realm()
                    realm.add(result.name, update: true)
                }

                catch let err as NSError {
                    print("Error with realm: " + err.localizedDescription)
                }

            }
            else
            {
                print("JSON data is nil. 123")
            }
    }

更新

我收到这个错误

致命错误：在展开可选值时意外发现 nil

user.name = result["name"]!.string

另外，我想从我的 do{} catch{} 中删除 !，但 swift 不允许我这样做。我如何解决它？

我的代码：

Alamofire.request(.POST, Data.loginEndpoint, parameters: parameters)
        .responseObject { (response: Response<Particulars, NSError>) in

            print(response.request)
            print(response.response)
            print(response.result)



            if let result = response.result.value
            {

                do{
                    let user = Particulars()
                    user.name = result["name"]!.string
                    user.apiToken = result["api_token"]!.string
                    let realm = try Realm()
                    realm.add(user, update: true)
                    print(Realm.Configuration.defaultConfiguration.fileURL)
                }

                catch let err as NSError {
                    print("Error with realm: " + err.localizedDescription)
                }

            }
            else
            {
                print("JSON data is nil. 123")
            }
    }

以下 sn-p 直接来自 Realm 文档。领域需要一个继承自其“对象”类型的类对象。您必须创建一个具有所有您需要的属性（姓名、电子邮件等）的类对象，当您收到响应时设置这些属性，然后将该对象保存到 Realm。

class Dog: Object {
  dynamic var name = ""
  dynamic var age = 0
}
class Person: Object {
  dynamic var name = ""
  dynamic var picture: NSData? = nil // optionals supported
  let dogs = List<Dog>()
}

// Use them like regular Swift objects
let myDog = Dog()
myDog.name = "Rex"
myDog.age = 1
print("name of dog: \(myDog.name)")

// Get the default Realm
let realm = try! Realm()

// Query Realm for all dogs less than 2 years old
let puppies = realm.objects(Dog).filter("age < 2")
puppies.count // => 0 because no dogs have been added to the Realm yet

// Persist your data easily
try! realm.write {
   realm.add(myDog)
}
