问题描述
旧版Alamofire。这就是我下载文件的方式
In older version of Alamofire. This is how I download file
let destinationPath = Alamofire.Request.suggestedDownloadDestination( directory: .documentDirectory, domain: .userDomainMask); Alamofire.download(.GET, urlString, destination: destinationPath) .progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in // print(totalBytesRead) } .response { request, response, _, error in let downloadedFilePath = destinationPath(URL(string: "")!, response!); NSUserDefaultsHelper.saveURL(downloadedFilePath, key: urlString); completion(downloadedFilePath, true); }但现在在新版本中,我的代码完全无法使用且没有Alamofire库中的类似功能。
But now in the new version, my code is completely unusable and there is no similar function in the Alamofire library.
请问任何想法?
推荐答案我曾经使用过这样的陈述:
I used to use this statements:
let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory) Alamofire.download( url, method: .get, parameters: parameters, encoding: JSONEncoding.default, headers: nil, to: destination).downloadProgress(closure: { (progress) in //progress closure }).response(completionHandler: { (DefaultDownloadResponse) in //here you able to access the DefaultDownloadResponse //result closure })详情请阅读更多在 Alamofire关于迁移到4.0的文档:
