Envoyer des paramètres POST avec MultipartFormData à l'aide de Alamofire, dans iOS Swift

J'ai trouvé la solution 🙂 enfin.

Nous pouvons ajouter des données dans la demande comme étant multipartformdata.

Ci-dessous mon code.

  Alamofire.upload(
        .POST,
        URLString: fullUrl, //http://httpbin.org/post
        multipartFormData: { multipartFormData in
            multipartFormData.appendBodyPart(fileURL: imagePathUrl!, name: "photo")
            multipartFormData.appendBodyPart(fileURL: videoPathUrl!, name: "video")
            multipartFormData.appendBodyPart(data: Constants.AuthKey.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"authKey")
            multipartFormData.appendBodyPart(data: "\(16)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"idUserChallenge")
            multipartFormData.appendBodyPart(data: "comment".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"comment")
            multipartFormData.appendBodyPart(data:"\(0.00)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"latitude")
            multipartFormData.appendBodyPart(data:"\(0.00)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"longitude")
            multipartFormData.appendBodyPart(data:"India".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"location")
        },
        encodingCompletion: { encodingResult in
            switch encodingResult {
            case .Success(let upload, _, _):
                upload.responseJSON { request, response, JSON, error in


                }
            case .Failure(let encodingError):

            }
        }
    )

EDIT 1: Pour ceux qui sont en train d'envoyer un tableau au lieu de float, int ou string, Ils peuvent convertir leur tableau ou tout type de structure de données en Json Chaîne, de passer cette chaîne JSON comme un fait normal de la chaîne. Et à analyser cette chaîne json au backend pour obtenir un exemplaire original de la matrice de

C'est de cette façon-je résoudre mon problème

let parameters = [
            "station_id" :        "1000",
            "title":      "Murat Akdeniz",
            "body":        "xxxxxx"]

let imgData = UIImageJPEGRepresentation(UIImage(named: "1.png")!,1)



    Alamofire.upload(
        multipartFormData: { MultipartFormData in
        //   multipartFormData.append(imageData, withName: "user", fileName: "user.jpg", mimeType: "image/jpeg")

            for (key, value) in parameters {
                MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }

        MultipartFormData.append(UIImageJPEGRepresentation(UIImage(named: "1.png")!, 1)!, withName: "photos[1]", fileName: "swift_file.jpeg", mimeType: "image/jpeg")
        MultipartFormData.append(UIImageJPEGRepresentation(UIImage(named: "1.png")!, 1)!, withName: "photos[2]", fileName: "swift_file.jpeg", mimeType: "image/jpeg")


    }, to: "http://platform.twitone.com/station/add-feedback") { (result) in

        switch result {
        case .success(let upload, _, _):

            upload.responseJSON { response in
                print(response.result.value)
            }

        case .failure(let encodingError): break
            print(encodingError)
        }


    }

Comme dans Swift 3.x pour charger une image avec le paramètre que nous pouvons utiliser en dessous de alamofire méthode de téléchargement-

static func uploadImageData(inputUrl:String,parameters:[String:Any],imageName: String,imageFile : UIImage,completion:@escaping(_:Any)->Void) {

        let imageData = UIImageJPEGRepresentation(imageFile , 0.5)

        Alamofire.upload(multipartFormData: { (multipartFormData) in

            multipartFormData.append(imageData!, withName: imageName, fileName: "swift_file\(arc4random_uniform(100)).jpeg", mimeType: "image/jpeg")

            for key in parameters.keys{
                let name = String(key)
                if let val = parameters[name!] as? String{
                    multipartFormData.append(val.data(using: .utf8)!, withName: name!)
                }
            }
        }, to:inputUrl)
        { (result) in
            switch result {
            case .success(let upload, _, _):

                upload.uploadProgress(closure: { (Progress) in
                })

                upload.responseJSON { response in

                    if let JSON = response.result.value {
                        completion(JSON)
                    }else{
                        completion(nilValue)
                    }
                }

            case .failure(let encodingError):
                completion(nilValue)
            }

        }

    }

Remarque: en Outre, si notre paramètre de tableau de paires de clefs alors nous pouvons
utilisation

 var arrayOfKeyPairs = [[String:Any]]()
 let json = try? JSONSerialization.data(withJSONObject: arrayOfKeyPairs, options: [.prettyPrinted])
 let jsonPresentation = String(data: json!, encoding: .utf8)

pour alamofire 4 utilisez cette ..

        Alamofire.upload(multipartFormData: { (multipartFormData) in

            multipartFormData.append(fileUrl, withName: "video")
       //fileUrl is your file path in iOS device and withName is parameter name

        }, to:"http://to_your_url_path")
        { (result) in
            switch result {
            case .success(let upload, _ , _):

                upload.uploadProgress(closure: { (progress) in

                    print("uploding")
                })

                upload.responseJSON { response in

                   print("done")

                }

            case .failure(let encodingError):
                print("failed")
                print(encodingError)

            }
        }
