在 SWIFT 中访问 IOS 设备上的视频文件路径 URL

如何解决在 SWIFT 中访问 IOS 设备上的视频文件路径 URL

我目前正在尝试使用 AWS IOS SDK 将视频文件上传到 AWSS3。这是我的过程：

// 我接受来自 UIIMagepicker 的视频数据 func imagePickerController(_picker: UIImagePickerController,didFinishPickingMediawithInfo info: [UIImagePickerController.InfoKey: Any]) {

    var videoPath = "VideoPath"
    if let videoURL = info[UIImagePickerController.InfoKey.mediaURL] {
        print("Video URL: \(videoURL)")
        
        
        
    
        uploadVideo(resource: "RandomName",type: "mov",url: videoURL as! URL)
        thumbnailImageView.image = 

}

//我然后调用这个上传视频函数，使视频的AWSS#transferutilityuploadtask。

let bucketName = “somebucketName"
var completionHandler: AWSS3TransferUtilityUploadCompletionHandlerBlock?
func uploadVideo(resource: String,type: String,url: URL){   //1
    
    
        
        let key = "Tester.mov"
        //let resource = Bundle.main.path(forResource: resource,ofType: type)!
        let url = url
       
    
    print(url)
    
    
    
  
    
    
    
       // let url = url
        
        let expression  = AWSS3TransferUtilityUploadExpression()
    
        expression.progressBlock = { (task: AWSS3TransferUtilityTask,progress: Progress) -> Void in
            print("Progress: \(progress.fractionCompleted * 100 ) %")//2
            print("Task state: \(task.progress)")
        
            
          if progress.isFinished{           //3
            print("100%...Upload Finished...")
            print("finished Uploading \(url)")
            
            dispatchQueue.main.async {
                var alert = UIAlertController(title: "Congratulations!",message: "Successfully Uploaded Video",preferredStyle: .alert)
                        self.present(alert,animated: true,completion:nil)
                
                alert.addAction(UIAlertAction(title: "OK",style: .default,handler: {
                    (action) in
                    
                    
                }))
            }
      
            //do any task here.
          }
        }
        
        expression.setValue("public-read-write",forRequestHeader: "x-amz-acl")   //4
        expression.setValue("public-read-write",forRequestParameter: "x-amz-acl")

        completionHandler = { (task:AWSS3TransferUtilityUploadTask,error:NSError?) -> Void in
            if(error != nil){
                print("Failure uploading file")
                
            }else{
            
                print("Success uploading file!\(print(task.response))")
                
               
            }
        } as? AWSS3TransferUtilityUploadCompletionHandlerBlock
        
        

        //5
    AWSS3TransferUtility.default().uploadFile(url,bucket: bucketName,key: String(key),contentType: "video",expression: expression,completionHandler: self.completionHandler).continueWith(block: { (task:AWSTask) -> AnyObject? in
            if(task.error != nil){
                
                print("Error uploading file: \(String(describing: task.error?.localizedDescription))")
                
            }
            if(task.result != nil){
                print("Starting upload...")
                
                
            }
            return nil
        })
    }

我还在我的应用程序委托中初始化了 AWSS3 传输连接。

这段代码在我的模拟器中完美运行。它从本地文件路径 url 获取文件并将其上传到我的 AWS Bucket。但是，当我在设备上运行它时，本地路径似乎无法访问视频数据。程序在“开始上传..”处停止 并显示 0 作为进度

我注意到从设备和 sumulator 创建的 url 是不同的。不确定如何同时接受，但由于某种原因，设备 url 没有提供正确的访问权限。
