Http Digest Authentication

Demonstrates the DigestAuth property to do HTTP Digest Authentication. VB.NET

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim http As New Chilkat.Http

' To use HTTP Digest Authentication:
http.Login = "myLogin"
http.Password = "myPassword"
http.DigestAuth = True

' If you would like to see the HTTP session log to see how 
' HTTP digest authentication worked.
http.SessionLogFilename = "c:/temp/qa_output/sessionLog.txt"

' Run the test using this URL with the credentials above.  
' (Works while httpbin.org keeps the test endpoint available.)
Dim jsonResponse As String = http.QuickGetStr("https://httpbin.org/digest-auth/auth/myLogin/myPassword")
If (http.LastMethodSuccess = False) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("Response status code: " & http.LastStatus)

Debug.WriteLine(jsonResponse)

' Output:

' Response status code: 200
' {
'   "authenticated": true, 
'   "user": "myLogin"
' }
