Add a Request Header to a REST Request

See more REST Examples

Demonstrates Rest.AddHeader, which adds an HTTP request header field. The 1st argument is the field name and the 2nd is the value. Adding a header whose name already exists replaces the previous value.

Dim success As Boolean = False

Dim rest As New Chilkat.Rest

'  Connect to the REST server.  The 3rd argument enables TLS (use True for HTTPS on port 443),
'  and the 4th enables automatic reconnection if the connection is dropped between requests.
Dim bTls As Boolean = True
Dim bAutoReconnect As Boolean = True
success = rest.Connect("example.com",443,bTls,bAutoReconnect)
If (success = False) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


'  Add request header fields.  The 1st argument is the field name and the 2nd is the value.
'  Adding a header with a name that already exists replaces the previous value.
rest.AddHeader("Accept","application/json")
rest.AddHeader("X-Custom-Header","example-value")

Dim responseText As String = rest.FullRequestNoBody("GET","/api/data")
If (rest.LastMethodSuccess = False) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If

Debug.WriteLine(responseText)
