使用Swift将文件上传到iOS应用的Dropbox

Question

我已完成本教程（https://blogs.dropbox.com/developers/2014/09/swift-apps-with-dropbox/），并成功将我的iOS应用与Dropbox相关联。不过，我想从我的应用上传一个文件到Dropbox。目前所有的教程都只有Objective C的代码，包括Dropbox的主要代码（https://www.dropbox.com/developers/core/start/ios）。 有谁知道如何用Swift做到这一点？

谢谢！

Answer 1

它的工作原理。

let textContent = "Hello Swift Upload" 

let textData:NSData? = textContent.dataUsingEncoding(NSUTF8StringEncoding) 

var client:DropboxClient? = Dropbox.authorizedClient 

if let cli = client { 
    cli.files.upload(path: "/Swift-Upload.txt", mode: Files.WriteMode.Add, autorename: false, clientModified: nil, mute: false, body: textData!) 
} 

Answer 2

我能够上传大（R）文件（> 800MB）这个（GIST）代码（SWIFT 2.2） - >

的iOS 10.12.3 SWIFT 3.0 SwiftyDropbox 4.1.1稍微更完整的答案上传的另一个150MB的文件上。

func files_saver(sourcePath: String) { 
    let textContent = "Blah Blah Blah" 
    let textData:NSData? = textContent.data(using: String.Encoding.utf8) as NSData? 

    let client = DropboxClientsManager.authorizedClient! 
    client.files.upload(path: sourcePath, input: textData as! Data).response { response, error in 
     if let metadata = response { 
      print("Uploaded file name: \(metadata.name)") 
      print("Uploaded file revision: \(metadata.rev)") 

      // Get file (or folder) metadata 
     } 
     if let error = error { 
      switch error as! CallError<SwiftyDropbox.Files.UploadError> { 
      case .routeError(let boxed, let requestId): 
       switch boxed.unboxed { 
       case .path(let failedPath): 
         //print("Failed update 2 path: \(failedPath)") 
         NotificationCenter.default.post(name: Notification.Name("dbFileCreationError"), object: nil, userInfo: nil) 
         break 

        default: 
         //print("Unknown \(error)") 
         break 
        } 
      case .internalServerError(let code, let message, let requestId): 
       //print("InternalServerError[\(requestId)]: \(code): \(message)") 
       NotificationCenter.default.post(name: Notification.Name("dbInternalServerError"), object: nil, userInfo: nil) 
       break 
      case .badInputError(let message, let requestId): 
       //print("BadInputError[\(requestId)]: \(message)") 
       NotificationCenter.default.post(name: Notification.Name("dbBadInputError"), object: nil, userInfo: nil) 
       break 
      case .authError(let authError, let requestId): 
       //print("AuthError[\(requestId)]: \(authError)") 
       NotificationCenter.default.post(name: Notification.Name("dbAuthError"), object: nil, userInfo: nil) 
       break 
      case .rateLimitError(let rateLimitError, let requestId): 
       //print("RateLimitError[\(requestId)]: \(rateLimitError)") 
       NotificationCenter.default.post(name: Notification.Name("dbRateLimitError"), object: nil, userInfo: nil) 
       break 
      case .httpError(let code, let message, let requestId): 
       //print("HTTPError[\(requestId)]: \(code): \(message)") 
       NotificationCenter.default.post(name: Notification.Name("dbHTTPError"), object: nil, userInfo: nil) 
       break 
      default: 
       break 
       } 
     } 
    }
