Enumerate REST Response Header Names

See more REST Examples

Demonstrates Rest.ResponseHdrName, which returns the field name of the response header at a zero-based index. The example enumerates all headers, pairing each name with its value.

Dim success As Long

Dim rest As New ChilkatRest
Dim bTls As Long
bTls = 1
Dim bAutoReconnect As Long

If (success = 0) Then
    Debug.Print rest.LastErrorText

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

'  Enumerate the response header fields by zero-based index.  ResponseHdrName returns the field name

For i = 0 To numHeaders - 1
    Dim name As String

    value = rest.ResponseHdrValue(i)
    If (rest.LastMethodSuccess = 0) Then
