如何在Swift3中将总模型对象作为Alamofire post方法的参数发送? [英] How to send total model object as a parameter of Alamofire post method in Swift3?

问题描述

我有一个像这样的模型课

I have a model class like this

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

我正在向该模型类添加数据

I'm adding data to that model class

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

之后，我转换为JSON，然后发布了

After that I converted to JSON then I posted

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

Alamofire仅接受其接受的参数，例如parameters = ["":"","",""]-->key value based，所以我尝试将模型转换为JSON，将JSON转换为字典，即使不接受其显示参数的问题.确实我需要像这样在Alamofire中将总模型对象作为post方法的参数发送:

Alamofire not accepting parameters only its accepting like parameters = ["":"","",""]-->key value based, so I tried to convert model to JSON, JSON to dictionary, even though not accepting its showing like parameters problem. Exactly I need total model object need to send as a parameter of post method in Alamofire like this:

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

推荐答案

由于Alamofire API仅接受字典，因此请自己创建字典！

Since the Alamofire API is only accepting dictionaries, create a dictionary yourself!

在模型类中添加一个名为toJSON的方法:

Add a method in the model class called toJSON:

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

然后在调用request时调用此方法:

Then call this method when calling request:

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

或者，使用SwiftyJSON:

Alternatively, use 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 )
