Question

我已经检查了一些关于实现此目的的旧帖子，但尚未找到解决方案。我想知道是否可以在不使用第三方框架的情况下执行此操作。如果NSURLSession可以帮助满员。我尝试过如下操作，但不支持URL错误：

错误提交请求：可选（错误域= NSURLErrorDomain代码= -1002“不支持的URL”UserInfo = {NSUnderlyingError = 0x7feb907f2a80 {错误域= kCFErrorDomainCFNetwork代码= -1002“（null）”}，NSErrorFailingURLStringKey = ftp.name.com ，NSErrorFailingURLKey =，NSLocalizedDescription =不支持的URL}）

我的代码：让urlString =“ftp.name.com”

    let fileData = NSData(contentsOfFile: xmlFile.stringValue)

    let config = NSURLSessionConfiguration.defaultSessionConfiguration()

    let userPasswordString = "user:password"

    let userPasswordData = userPasswordString.dataUsingEncoding(NSUTF8StringEncoding)

    let base64EncodedCredential = userPasswordData!.base64EncodedDataWithOptions(.Encoding64CharacterLineLength)

    let authString = "Basic \(base64EncodedCredential)"

    config.HTTPAdditionalHeaders = ["Authorization" : authString]

    let session = NSURLSession(configuration: config)


    if let percentURLString = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())
    {

    let url = NSURL(string: percentURLString )


    let request = NSMutableURLRequest(URL: url!)

    request.HTTPMethod = "POST"

    request.HTTPBody = fileData

        print("FTP Request :\(request)")

    let task = session.dataTaskWithRequest(request, completionHandler:
    {
        (data, response, error) in

        if (error != nil)
        {
            print("error submitting request: \(error)")
            return
        }

        if let httpResponse = response as? NSHTTPURLResponse
        {
            if httpResponse.statusCode != 200
            {
                print("response was not 200: \(response)")
                return
            }

            else if httpResponse.statusCode == 200
            {
                print("FIle sent")
            }
        }

        })


    task.resume()


    }

}
