无法使用GCDWebServer快速在Web浏览器上获取视频

Question

我创建了一个小型演示应用程序，其中该应用程序使用UIImagePickerController从iPhone访问图像和视频。当我选择任何图像或视频时，应用程序会在文档目录中创建其副本（图像或视频）。并使用GCDWebserver在iPhone上创建Web服务器，并需要公开所选的图像或视频。但这行不通。

这是示例代码，不确定我哪里可能出错。

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var btnselect: UIButton!
let videoPicker = UIImagePickerController()

@IBAction func btnSelect(_ sender: Any) {

        if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
            let myPickerController = UIImagePickerController()
            myPickerController.delegate = self;
            myPickerController.sourceType = .photoLibrary
            myPickerController.allowsEditing = false
            self.present(myPickerController, animated: true, completion: nil)
        }

    }

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

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

    // 1. saving video to documents directory

      let videoURL = info[UIImagePickerController.InfoKey.mediaURL] as! NSURL
            let videoData = NSData(contentsOf: videoURL as URL)
            let path = try! FileManager.default.url(for: FileManager.SearchPathDirectory.documentDirectory, in: FileManager.SearchPathDomainMask.userDomainMask, appropriateFor: nil, create: false)

            let newPath = path.appendingPathComponent("/myTestVideo.mp4")
            do {
                try videoData?.write(to: newPath)
            } catch {
                print(error)
            }


 // 2. Create web server on iPhone using GCDWebServer

        let webServer = GCDWebServer()
        webServer.addDefaultHandler(forMethod: "GET", request: GCDWebServerRequest.self, processBlock: {request in
        return GCDWebServerDataResponse(newPath)

       })
       webServer.start(withPort: 8080, bonjourName: "GCD Web Server")

}
}

我需要此GCD Web服务器托管/访问此选定的（图像或视频）。

假设它可能是按照错误的路径

let newPath = path.appendingPathComponent("/myTestVideo.mp4")

生产..../Documents//myTestVideo.mp4

尝试从附加路径组件中删除反斜杠。

let newPath = path.appendingPathComponent("myTestVideo.mp4")

此外，该问题也有可能与“file://”前缀有关。如果之前的建议没有帮助，请尝试删除前缀。
