Swift How to Unzip file from URL with Alamofire and SSZipArchive - ios

Question

func downLoad(fileName:String) {
let urlString : String = "\(myurl)\(fileName)"
var localPath: NSURL?
let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)
Alamofire.download(urlString, method: .get, encoding: JSONEncoding.default, to: destination)
.downloadProgress(queue: DispatchQueue.global(qos: .utility)) { progress in
print("Progress: \(progress.fractionCompleted)")
}
.validate { request, response, temporaryURL, destinationURL in
// Custom evaluation closure now includes file URLs (allows you to parse out error messages if necessary)
return .success
}
.responseJSON { response in
debugPrint(response)
print(response.destinationURL?.path)
print(response.destinationURL?.absoluteString)
let unzipDirectory = self.unzipPath(fileURL:fileName)
let success = SSZipArchive.unzipFile(atPath: (response.destinationURL?.path)!, toDestination: unzipDirectory!)
print(success)
if !success {
return
}
}
}
func unzipPath(fileName:String) -> String? {
let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String
let url = NSURL(fileURLWithPath: path)
let pathComponent = url.appendingPathComponent("test\(fileName)")
do {
try FileManager.default.createDirectory(at: pathComponent!, withIntermediateDirectories: true, attributes: nil)
} catch {
return nil
}
return pathComponent?.absoluteString
}
i get right path in response.destinationURL
but success is false
i tried atPath : to response.destinationURL?.path and
response.destinationURL?.absoluteString
but failed too
What i am doing wrong
destinationURL?.path return this
Optional("/Users/MyUser/Library/Developer/CoreSimulator/Devices/3FBAD207-E5AB-4FC1-8199-2269A1249D97/data/Containers/Data/Application/CB1C2EF5-3100-430B-B869-774C09B8EA7F/Documents/testFile.zip")
response.destinationURL?.absoluteString
return this
Optional("file:///Users/MyUser/Library/Developer/CoreSimulator/Devices/3FBAD207-E5AB-4FC1-8199-2269A1249D97/data/Containers/Data/Application/CB1C2EF5-3100-430B-B869-774C09B8EA7F/Documents/testFile.zip")
i think this is correct URL
why failed unzip?

By looking at your code, the path you are using for the source is perfect.
For the destination path, try updating it to
func unzipPath(fileName:String) -> String? {
let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString
let pathWithComponent = path.appendingPathComponent("test\(fileName)")
do {
try FileManager.default.createDirectory(atPath: pathWithComponent, withIntermediateDirectories: true, attributes: nil)
} catch {
return nil
}
return pathWithComponent
}
Try and share the results.
