如何在Swift3中将总模型对象作为Alamofire post方法的参数发送？

Question

我有这样的模型类

class Example() {
  var name:String?
  var age:String?
  var marks:String? 
}

我正在向该模型类添加数据

let example = Example()
example.name = "ABC"
example.age = "10"
example.marks = "10" 

之后我转换为JSON然后我发布了

Alamofire.request(URL, method:.post, parameters: example)

Alamofire不接受参数只接受它parameters = ["":"","",""]-->key value based,所以我试图将模型转换为JSON,JSON转换为字典,即使不接受它显示的参数问题.我需要总模型对象需要在Alamofire中作为post方法的参数发送,如下所示:

let example = Example()
Alamofire.request(URL, method:.post, parameters: example)

由于Alamofire API仅接受字典,因此请自行创建字典!

在模型类中添加一个名为的方法toJSON:

func toJSON() -> [String: Any] {
    return [
        "name": name as Any,
        "age": age as Any,
        "marks": marks as Any
    ]
}

然后在调用时调用此方法request:

Alamofire.request(URL, 
    method:.put, 
    parameters:example.toJSON(), 
    encoding:JSONEncoding.default, 
    headers :Defines.Api.Headers )

或者,使用SwiftyJSON:

func toJSON() -> JSON {
    return [
        "name": name as Any,
        "age": age as Any,
        "marks": marks as Any
    ]
}

用法:

Alamofire.request(URL, 
    method:.put, 
    parameters:example.toJSON().dictionaryObject, 
    encoding:JSONEncoding.default, 
    headers :Defines.Api.Headers )
