    Alamofire.upload(multipartFormData:{ MultipartFormData in

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

        for img in arrImage {

            guard let imgData = img.jpegData(compressionQuality: 1) else { return }
            MultipartFormData.append(imgData, withName: imageKey, fileName: FuncationManager.getCurrentTimeStamp() + ".jpeg", mimeType: "image/jpeg")
        }

    },usingThreshold:UInt64.init(),
      to: "URL",
        method:.post,
        headers:["Content-type": "multipart/form-data",
                 "Content-Disposition" : "form-data"],
        encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, , ):

                upload.uploadProgress(closure: { (Progress) in
                    print("Upload Progress: \(Progress.fractionCompleted)")
                })

                upload.responseJSON { response in
                    switch(response.result) {
                    case .success(_):
                        let dic = response.result.value as! NSDictionary
                        if (dic.object(forKey:  "status")! as! Int == 1){
                            withblock(dic.object(forKey: "data") as AnyObject)
                        }else if (dic.object(forKey: Message.Status)! as! Int == 2){
                            print("error message")

                        }else{

                    case .failure(_):
                        print("error message")
                    }
                }

请参考以下代码.

public class func callsendImageAPI(param:[String: Any],arrImage:[UIImage],imageKey:String,URlName:String,controller:UIViewController, withblock:@escaping (_ response: AnyObject?)->Void){

    let headers: HTTPHeaders
    headers = ["Content-type": "multipart/form-data",
               "Content-Disposition" : "form-data"]
    
    AF.upload(multipartFormData: { (multipartFormData) in
        
        for (key, value) in param {
            multipartFormData.append((value as! String).data(using: String.Encoding.utf8)!, withName: key)
        }
        
        for img in arrImage {
            guard let imgData = img.jpegData(compressionQuality: 1) else { return }
            multipartFormData.append(imgData, withName: imageKey, fileName: FuncationManager.getCurrentTimeStamp() + ".jpeg", mimeType: "image/jpeg")
        }
        
        
    },usingThreshold: UInt64.init(),
      to: URL.init(string: URlName)!,
      method: .post,
      headers: headers).response{ response in
        
        if((response.error != nil)){
            do{
                if let jsonData = response.data{
                    let parsedData = try JSONSerialization.jsonObject(with: jsonData) as! Dictionary<String, AnyObject>
                    print(parsedData)
                    
                    let status = parsedData[Message.Status] as? NSInteger ?? 0
                    
                    if (status == 1){
                        if let jsonArray = parsedData["data"] as? [[String: Any]] {
                            withblock(jsonArray as AnyObject)
                        }
                        
                    }else if (status == 2){
                        print("error message")
                    }else{
                        print("error message")
                    }
                }
            }catch{
                print("error message")
            }
        }else{
             print(response.error!.localizedDescription)
        }
    }
}
