Get a REST Response Header Value by Index

See more REST Examples

Demonstrates Rest.ResponseHdrValue, which returns the value of the response header at a zero-based index. The same index used with ResponseHdrName gives the corresponding field name.

Dim success As Long
success = 0

Dim rest As New ChilkatRest
Dim bTls As Long
bTls = 1
Dim bAutoReconnect As Long
bAutoReconnect = 1
success = rest.Connect("example.com",443,bTls,bAutoReconnect)
If (success = 0) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

success = rest.SendReqNoBody("GET","/api/items/123")
If (success = 0) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

Dim statusCode As Long
statusCode = rest.ReadResponseHeader()
If (statusCode < 0) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

'  Return the value of the response header at a zero-based index.  Use the same index with
'  ResponseHdrName to get the corresponding field name.
Dim numHeaders As Long
numHeaders = rest.NumResponseHeaders
Dim i As Long
For i = 0 To numHeaders - 1
    Dim value As String
    value = rest.ResponseHdrValue(i)
    If (rest.LastMethodSuccess = 0) Then
        Debug.Print rest.LastErrorText
        Exit Sub
    End If

    Debug.Print "Header " & i & " value: " & value
