swift - 使用 Swift 上传文件到 FTP 服务器

Question

我正在使用框架 RebekkaTouch 将文件从我的 Swift 应用程序上传到 FTP 服务器，就像:

if let URL = NSBundle.mainBundle().URLForResource("myFile", withExtension: "txt") {
    let path = "myFile.txt"
    session.upload(URL, path: path) {
        (result, error) -> Void in
        print("result:\n\(result), error: \(error)\n\n")
    }
}

这非常适合我通过 Xcode 手动上传的文件。但是我似乎无法找到我下载并动态存储在本地 Documents 目录中的文件的文件路径。

说，我知道我有这个文件:/private/var/mobile/Containers/Data/Application/3D92EA55-01E0/Documents/SomeFile.txt

我知道它在那里，因为我在遍历 NSFileManager.defaultManager() 后获得了路径，但我不能转换它没有 NSURL 所以我可以上传它。

有什么想法吗？

这是死亡的地方:

let file = "myFile.txt"
if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
    //path will be stored here
    let sPath = dir.stringByAppendingPathComponent(file);
    print(sPath) //  printing the file path

    let url: NSURL = NSURL(string: sPath)!

    let destinationFile = "myFile.txt"
    FTPSession.upload(url, path: destinationFile) { // <-- Dies here
        (result, error) -> Void in
        print("- Result:\n\(result), error: \(error)\n\n")
    }
}

这是例子

This code is fully tested on Swift 2.0

 let file = "SomeFile.txt"
        if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
           //path will be stored here
            let sPath = dir.stringByAppendingPathComponent(file);

      print(sPath) //  printing the file path
        }

比你可以执行上传

EDIT AS ASKED IN COMMENT ABOUT CONVERTING STRING TO NSURL

let URL: NSURL = NSURL(string: stringofURL)! //replace stringofURL to sPath

UPDATED YOUR CODE

let file = "myFile.txt"
if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
    //path will be stored here
    let sPath = dir.stringByAppendingPathComponent(file);
    print(sPath) //  printing the file path

    let url: NSURL = NSURL(string: sPath)!

    let destinationFile = "myFile.txt"
    session.upload(url, path: destinationFile) { // here was the error it should be session not FTPsession
        (result, error) -> Void in
        print("- Result:\n\(result), error: \(error)\n\n")
    }
}
