我正在尝试发送带有参数的照片，但要注意的是我想将JSON数组发送到服务器。看来Alamofire没有发送列表的方法Data，那么还有什么替代方法呢？

问题的关键部分是：

var encodedTags: [Data] = tags.map({ return $0.data(using: .utf8)!})
            mpd.append(encodedTags, withName: key)

在此上传调用中：

let parameters: [String: Any] = ["username": "TheCooliest", ..., "tags": ["KoolKid", "TheKooliest", "BetterThanKimK"]    
...

upload(multipartFormData: { (mpd) in
        mpd.append(url, withName: "file", fileName: "weeknd.jpg")
        for (key, value) in parameters {
            if let tags = value as? [String], key == "tags" {
                var encodedTags = tags.map({ return $0.data(using: .utf8)!})
                mpd.append(encodedTags, withName: key)

            }
        }
    }

根据Apple文档,它是存储在主存储器中的图像,但这些图像如何用于制作电影？

我似乎无法将照片正确上传到Django.这是问题所在.

request.FILES是空的.然而,在身体中我看到一堆乱码(这将是照片数据).我试过这个让它工作但它仍然显示为空:

在Django:

class UploadPhoto(APIView):
    parser_classes = (MultiPartParser, FormParser, )
    authentication_classes = (TokenAuthentication,)
    permission_classes = (IsAuthenticated,)
    def post(self, request, format=None):
        print(request.FILES)
        return Response(status=status.HTTP_200_OK)

在iOS中:

    func photoUploader(photo: UIImage,  completion: @escaping (Bool) -> Void) {
    let imageData = UIImageJPEGRepresentation(photo, 0.8)

    guard let authToken = Locksmith.loadDataForUserAccount(userAccount: "userToken")?["token"] as? String else {
        return
    }

    let headers: HTTPHeaders = ["Authorization": authToken]
    var url: URLRequest?

    do {
        url = try URLRequest(url: EntityURLs.uploadPhotoURL, method: .post, headers: headers)
    } catch {
        print("Error")
    }

    if let url = …
