Using NMSSH and NMSFTP, I am able to connect to our company's remote SFTS server. I am also able to upload files to an "Incoming" folder in SFTS site. The issue is, when I try read a JSON file in the "Outgoing" folder using NMSFTP Contents(ofFile:), I keep getting NIL value. I am able to get the file name using contentsOfDirectory(atPath:). Any help is appreciated. The remote Windows 2019 server had read/write permissions for all folders I am dealing with
XCODE 12.0
iOS 14.0
Here is my code:
DispatchQueue.global(qos: .userInitiated).async { () in
let empDownloadSession = NMSSHSession(host: "host_site:22", andUsername: "user name")
empDownloadSession.connect()
if empDownloadSession.isConnected{
print("Employee download session connected")
empDownloadSession.authenticateBy(inMemoryPublicKey: nil, privateKey: self.privKey, andPassword: "password entered here")
if empDownloadSession.isAuthorized == true {
print("SFTP employee download session is authorized")
let downloadSession = NMSFTP(session: empDownloadSession)
downloadSession.connect()
if downloadSession.isConnected {
print("Employee download session is connected")
} else {
print("Error: employee download session not connected")
return
}
guard let employeeListContents = downloadSession.contentsOfDirectory(atPath: "/MailTracking/Test/Outgoing")
else {
print("Unable to read contents of file in SSH site")
return
}
print("Printing Contents of file at path")
print(employeeListContents)
print("Employee data captured")
guard let employeeList = downloadSession.contents(atPath: "/MailTracking/Test/Outgoing/")
// this is where the issue is. I get nil value
else {
print("Unable to read contents of file in SSH site")
return
}
print("Printing Contents of file at path")
print(employeeList)
do {
if let json = try JSONSerialization.jsonObject(with: self.employeeList!, options: []) as? [String : Any] {
if let empList1 = json["employees"] as? [String] {
print("Employee Details ")
print(empList1)
}
}
} catch let error as NSError {
print("Unable to create json file from employeeList data")
print("Failed to load \(error.localizedDescription)")
}
} else {
print("empDownloadSession not authorized")
}
} else {
print ("empDownloadSession is NOT connected")
}
empDownloadSession.disconnect()
}
