Comment envoyer POST demande avec le paramètre et le corps pour les données JSON dans Swift 3 en utilisant Alamofire 4?

URL de postier ajoutée ci-dessous .  enter image description here

Code actuel:

let baseUrl = "abc.com/search/"
let param  =  [
        "page":"1",
        "size":"5",
        "sortBy":"profile_locality"
    ]

    let headers = [
        "Content-Type": "application/json"
    ]


    Alamofire.SessionManager.default.request("\(baseUrl)field", method: .post,parameters: param, encoding: JSONEncoding.default, headers: headers).responseJSON { response in
        print(response.request ?? "no request")  // original URL request
        if(response.response?.statusCode != nil){
            print("done")
            if self.checkResponse(response.response!.statusCode){
                let json = JSON(data: response.data!)
                //print("at_LeadStop json \(json)")
                return completionHandler(json, false)

            } else {
                return completionHandler(JSON.null, true)
            }
        } else {
            print("gone")
            return completionHandler(JSON.null, true)
        }}

Je ne sais pas comment ajouter une demande de corps via ce code. S'il vous plaît aidez-moi à slove ce problème.

Vous mélangez deux choses ici, page, size et sortBy est que vous devez transmettre avec la chaîne d'URL comme chaîne de requête. Maintenant votre corps est demandé est JSON Array et vous pouvez poster un tableau avec Alamofire uniquement en utilisant URLRequest. Alors essayez comme ça.

let baseUrl = "abc.com/search/"
let queryStringParam  =  [
    "page":"1",
    "size":"5",
    "sortBy":"profile_locality"
]
//Make first url from this queryStringParam using URLComponents
var urlComponent = URLComponents(string: baseUrl)!
let queryItems = queryStringParam.map  { URLQueryItem(name: $0.key, value: $0.value) }
urlComponent.queryItems = queryItems

//Now make `URLRequest` and set body and headers with it
let param = [
    [
        "fieldName" : "abc",
        "fieldValue":"xyz"
    ],
    [
        "fieldName" : "123",
        "fieldValue":"789"
    ]
]
let headers = [ "Content-Type": "application/json" ]
var request = URLRequest(url: urlComponent.url!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: param)
request.allHTTPHeaderFields = headers

//Now use this URLRequest with Alamofire to make request
Alamofire.request(request).responseJSON { response in
    //Your code
}

Essayez ceci: Utiliser Encodage personnalisé 

 struct JSONStringArrayEncoding: ParameterEncoding {
    private let array: [[String : Any]]

    init(array: [[String : Any]]) {
        self.array = array
    }

    func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var urlRequest = try urlRequest.asURLRequest()

        let data = try JSONSerialization.data(withJSONObject: array, options: [])

        if urlRequest.value(forHTTPHeaderField: "Content-Type") == nil {
            urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
        }

        urlRequest.httpBody = data

        return urlRequest
    }
}

Appeler 

let values  = [
            [
                "fieldName" : "abc",
                "fieldValue":"xyz"
            ],
            [
                "fieldName" : "123",
                "fieldValue":"789"
            ]
        ]

        let param  =  [
            "page":"1",
            "size":"5",
            "sortBy":"profile_locality"
        ]

        let parameterEncoding = JSONStringArrayEncoding.init(array: values)

        Alamofire.request("url", method: .post, parameters: param, encoding:parameterEncoding  ).validate().response { (responseObject) in
            // do your work
        }
