ios - Swift 3 上传视频到服务器

Question

我正在尝试将视频上传到我的服务器。我目前可以很好地上传图片，但是在尝试上传视频时，我不知道如何处理这个问题。我目前使用以下方式上传图片:

at "let image"当我从相册中选择视频时抛出错误。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{

    let imageUrl          = info[UIImagePickerControllerReferenceURL] as! NSURL
    let imageName         = imageUrl.lastPathComponent
    let documentDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!
    let photoURL          = NSURL(fileURLWithPath: documentDirectory)
    let localPath         = photoURL.appendingPathComponent(imageName!)
    let image             = info[UIImagePickerControllerOriginalImage]as! UIImage
    let data              = UIImagePNGRepresentation(image)

Answer 1

在这里，我们使用 Alamofire 库上传视频，请按照以下步骤轻松上传视频。第 1 步:- 添加扩展程序并选择视频

extension UploadStatusViewController : UIImagePickerControllerDelegate,UINavigationControllerDelegate
{
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

        if let mediaType = info[UIImagePickerControllerMediaType] as? String {

            if mediaType == "public.movie" {
                print("Video Selected")
                let videoURL = info[UIImagePickerControllerMediaURL] as! URL

                selectedVideoURL = videoURL
                self.playVideo(videoURL)
            }
        }
        dismiss(animated: true, completion: nil)

    }

    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        dismiss(animated: true, completion: nil)
    }
}

第 2 步:- 添加 Alamofire 库并设置此方法

func callAPIForUploadVideo{

        ShowLoaderOnView()
        Alamofire.upload(multipartFormData: { (multipartFormData) in
            // code
// here you can upload only mp4 video
                multipartFormData.append(self.selectedVideoURL!, withName: "File1", fileName: "video.mp4", mimeType: "video/mp4")
// here you can upload any type of video            
                //multipartFormData.append(self.selectedVideoURL!, withName: "File1")
                 multipartFormData.append(("VIDEO".data(using: String.Encoding.utf8, allowLossyConversion: false))!, withName: "Type")

        }, to: /* Set Url Here */ , encodingCompletion: { (result) in
            // code
            switch result {
            case .success(request: let upload, streamingFromDisk: _, streamFileURL: _):
                upload.validate().responseJSON {
                    response in
                    HideLoaderOnView()
                    if response.result.isFailure {
                        debugPrint(response)
                    } else {
                        let result = response.value as! NSDictionary
                        print(result)
                    }
                }
            case .failure(let encodingError):
                HideLoaderOnView()
                NSLog((encodingError as NSError).localizedDescription)
            }
        })
    }
