斯威夫特3上传视频到服务器

Question

我想上传视频到我的服务器。我目前可以上传图片，但在尝试上传视频时，我不知道如何处理此问题。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发生错误。

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

您可以使用Alamofire（https://github.com/Alamofire/Alamofire）文件的上传和下载

请查看以下alamofire例子上传文件

例1：上传数据

let imageData = UIPNGRepresentation(image)! 

Alamofire.upload(imageData, to: "https://httpbin.org/post").responseJSON { response in 
    debugPrint(response) 
} 

例2：上传文件

let fileURL = Bundle.main.url(forResource: "video", withExtension: "mov") 

Alamofire.upload(fileURL, to: "https://httpbin.org/post").responseJSON { response in 
    debugPrint(response) 
} 

例3：上传多部分表单数据

Alamofire.upload(
    multipartFormData: { multipartFormData in 
     multipartFormData.append(unicornImageURL, withName: "unicorn") 
     multipartFormData.append(rainbowImageURL, withName: "rainbow") 
    }, 
    to: "https://httpbin.org/post", 
    encodingCompletion: { encodingResult in 
     switch encodingResult { 
     case .success(let upload, _, _): 
      upload.responseJSON { response in 
       debugPrint(response) 
      } 
     case .failure(let encodingError): 
      print(encodingError) 
     } 
    } 
)

这里，我们已经上传使用Alamofire库视频，请按照下面的步骤，因此您可以轻松上传视频。 第1步： - 添加扩展名并选择视频

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，并设置该方法

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) 
      } 
     }) 
    }
