Ios 如何使用SwiftHydroPBOX下载文件?路径错误

Ios 如何使用SwiftHydroPBOX下载文件?路径错误,ios,swift,swiftydropbox,Ios,Swift,Swiftydropbox,我正在尝试使用SwiftHydropbox下载一个文件,但路径有问题。我在mi Dropbox“prueba.txt”中有一个文件: 这是我用来在我的应用程序中下载的代码 import UIKit import SwiftyDropbox let clientDB = DropboxClientsManager.authorizedClient class Controller: UIViewController { override func viewDidLoad() { s

我正在尝试使用SwiftHydropbox下载一个文件,但路径有问题。我在mi Dropbox“prueba.txt”中有一个文件:

这是我用来在我的应用程序中下载的代码

import UIKit
import SwiftyDropbox

let clientDB = DropboxClientsManager.authorizedClient

class Controller: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.

    DropboxClientsManager.authorizeFromController(UIApplication.shared, controller: self, openURL: {
        (url: URL) -> Void in UIApplication.shared.open(url)
    })

    let fileManager = FileManager.default
    let directoryURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
    let destURL = directoryURL.appendingPathComponent("/test.txt")
    let destination: (URL, HTTPURLResponse) -> URL = { temporaryURL, response in
        return destURL
    }

    clientDB?.files.download(path: "/prueba.txt", overwrite: true, destination: destination)
        .response{ response, error in
            if response != nil{
                self.cargarDatosCliente()
                //print (response)
            } else if let error = error{
                print (error)
            }
        }

        .progress{ progressData in
            print(progressData)
        }
    }
}
我尝试了不同的方法,但总是得到与“路径”相同的问题,错误总是
path/not\u found/…
我尝试了其他的方法,但也是同样的问题。 你能帮我吗?我的错在哪里

谢谢

问题在于“/prueba.txt”是一个本地文件路径。Dropbox希望您为其远程服务器提供一个文件路径

您可以使用和检索这些

例如,如果要检索应用程序或dropbox根文件夹中的文件路径,请使用:

var path = ""
clientDB?.files.listFolder(path: path).response(completionHandler: { response, error in
            if let response = response {
                let fileMetadata = response.entries
                if response.hasMore {
                    // Store results found so far
                    // If there are more entries, you can use `listFolderContinue` to retrieve the rest.
                } else {
                    // You have all information. You can use it to download files.
                }
            } else if let error = error {
                // Handle errors
            }
        })
fileMetadata包含所需的路径。例如,您可以获得第一个文件的路径,如下所示:

let path = fileMetadata[0].pathDisplay

如果您从API获取有关文件的元数据,则这将是FileMetadata对象的“pathLower”属性

client?.files.download(path: fileMetadata.pathLower!, overwrite: true, destination: destination)
                            .response { response, error in
                                if let response = response {
                                    print(response)
                                } else if let error = error {
                                    print(error)
                                }
                            }
