HTTP Digest-MD5 Authentication Testing with httpbin.org

See more HTTP Examples

The URL https://httpbin.org/digest-auth/auth/user/passwd is password protected with user="user" and password="passwd". It requires Digest-MD5 authentication. Chilkat will automatically handle Digest-MD5 authentication as required by the server response. In this case, however, the server will fail the authentication unless a Cookie is included in the request. The cookie can have any name and any value. (Yes, this is ridiculous, and many developers have probably spent countless hours assuming their Digest-MD5 implementations were incorrect.) VB.NET

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

Dim http As New Chilkat.Http

http.Login = "user"
http.Password = "passwd"

' Add a cookie to satisfy httpbin.org's desire for cookies..
' Otherwise, it will fail the perfectly valid Digest-MD5 authentication.
http.SetRequestHeader("Cookie","something=""something""")

Dim strResponse As String = http.QuickGetStr("https://httpbin.org/digest-auth/auth/user/passwd")
If (http.LastMethodSuccess = False) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


Debug.WriteLine(strResponse)

Dim status As Integer = http.LastStatus
Debug.WriteLine("response status code = " & status)


' The output of this program is:
' 
' 	{ 
' 	  "authenticated": true, 
' 	  "user": "user"
' 	} 
' 
' 	response status code = 200
