如何使用Alamofire发送复杂类型请求

Question

I have to send request to Server. Saving user record. The user record contains the model of Subject, and that Subject contains multiple model and arrays also. let me give you little example.

@ignore 
public class SubjectModel: Codable {
    public var Name : String? = ""
    public var Price : Int? = 0
    public var ISBN : String? = ""
    public var listTeachers : [TeacherModel]? = []

}

public class TeacherModel: Codable {
    public var Name : String? = ""
    public var PhoneNo : String? = ""
    public var listClasses: [ClassModel]? = []

}

public class ClassModel: Codable {
    public var Name : String? = ""
    public var Section : String? = ""
     public var RoomNo : String? = ""


}

So I have to send the SubjectModel, and as you can see the SubjectModel contains multiple Arrays of InnerModel. All models are codable.

So the JSON that my webservice required must look like following

{ApiKey:"asas-dsadas-xyz-xyz","StudentSubjects":{Now here come arrays,"InnerList":[here comes inner arrays ]}}

Problems:

1. As you can see I have Implemented Codables to my model, so I am getting good and expected Json, But I am not able to attach the Api Key
2. Also I have no Idea how to send such thing as Parameters of Alamofire.
3. Or You can say it simply like" How to send the StudentSubject and Apikey also in json format "

Please help me, I am bashing my head but not able to get the reply on server side, infact I am getting null.

UPDATE1: This is how I am doing it

let jsonEncoder = JSONEncoder()
    let jsonData = try jsonEncoder.encode(mySubjectModel)
    let json = String(data:jsonData,encoding:String.Encoding.utf8)


let parameter: [String:AnyObject] = [
            "StudentSubjects" : json as AnyObject,
            "ApiKey":"xyz-zyz-zyz"
    ]

And then Sending it like this

Alamofire.request(Common.URL+ServiceMethodName, method: .post, parameters:parameter, encoding: JSONEncoding.default, headers: nil) .responseJSON { response in

Answer 1

What you need is to use this method (I'm not sure if you need PUT or POST but it should be POST)

Alamofire.request(.POST, "http://myserver.com", parameters: parameters, encoding: .JSON)
    .responseJSON { request, response, JSON, error in
        print(response)
        print(JSON)
        print(error)
    }

parameters object is

let parameters: [String: AnyObject] = [
    "ApiKey" : "asas-dsadas-xyz-xyz",
    "StudentSubjects" : yourStudnetSubjectsList
]

Alamofire will do the transformation to JSON for you.
