ios - 如何在 alamofire 多部分数据中传递字典？ iOS swift3

Question

我想制作一本字典并将这些数据与使用 alamofire 上传的视频文件一起传递。下面是我的 json。

{
    "taskid": "2",
    "task_type": "N\/A",
    "fileName": null,
    “videofile”:
    "task": [
        {
            “Cid": 1,
            “Start”: "00:00:00",
            “End”: "00:00:00"
        },

        {
            “Cid": 2,
            “Start”: "00:00:00",
            “End”: "00:00:00"
        },
        {
           “Cid": 3,
            “Start”: "00:00:00",
            “End”: "00:00:00"
        },
    ]
}

下面字典数组的代码应该是什么？如何通过？

multipartFormData.append((self.singleTonFile?.fileUrl)! , withName: "videofile" , fileName: fileNameOnly + ".webm", mimeType: "video/webm")
multipartFormData.append(self.singleTon.userid.data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: "userid")

multipartFormData.append(self.singleTon.taskid.data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: "taskid")

multipartFormData.append(self.singleTon. filename.data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: "filename")

@里迪。 - 检查我的一个样本的解决方案。这是一种不同的格式。但遵循字典数组作为参数..

for i in 0..<self.singleTon.individualTask.count
        {
            let dictTask = ["id":self.singleTon.individualTask[i],
                        "start_time":self.singleTon.individualTaskStartTime[i],
                        "end_time":self.singleTon.individualTaskEndTime[i],

            parameters.append(dictTask as [String : AnyObject])
        }
           ]
        var dataParameters = Data()
        do
        {
            dataParameters = try JSONSerialization.data(withJSONObject: parameters, options: JSONSerialization.WritingOptions(rawValue: 0))
            let objectString = String(data: dataParameters, encoding: .utf8)

            print("objectString : ", objectString!)

                         "display":self.singleTon.display,
                         ]

        var dataAlamoDict = Data()

//这是为了测试json序列化

do

            let objectString = String(data: dataParameters, encoding: .utf8)

            print("objectString : ", objectString!)
        }

   //This is ur alamofire format


        Alamofire.upload(multipartFormData: { (multipartFormData) in
