ios - IOS中带参数上传多部分图片

Question

我是 IOS 新手，想要将带有参数的图像上传到服务器，但它没有上传。我尝试了很多引用 alamofire 和 base64 但没有任何效果对我有用。我是否错过了任何事情，对理解这一点有任何帮助吗？

提前致谢。请帮我解决问题

下面是我的代码:

@IBAction func submitBtnClicked(_ sender: Any)

{
    //parameters
    var number: Int?
    number = 47000482
    var srNumber = String(format:"%d",number!)
    var urlString: String = filePath!.absoluteString
    var parameters = ["s_no":srNumber, "count":"1"]
    let imgData = UIImageJPEGRepresentation(self.chosenImage!, 0.5)

    print(parameters)
    print(imgData)

    Alamofire.upload(multipartFormData: { (multipartFormData) in

        multipartFormData.append(imgData!, withName:"filestream", fileName:(self.filePath?.lastPathComponent)!, mimeType: "image/jpeg")

        for (key, value) in parameters {
            multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName:key)
        }
    }, to:"https://********************")

    { (result) in

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

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

            upload.responseJSON { response in
                print(response.request)  // original URL request
                print(response.response) // URL response
                print(response.data)     // server data
                print(response.result)   // result of response serialization

                if let JSON = response.result.value {
                    print("JSON: \(JSON)")
                }
            }

        case .failure(let encodingError):
            //self.delegate?.showFailAlert()
            print(encodingError)
        }
    }
}
