See more REST Examples

Demonstrates how to examine the HTTP response status code and text when using the REST object. B4X

Dim success As Boolean = False

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

Dim rest As ChilkatRest
rest.Initialize("rest")

'  We're going to check https://authenticationtest.com/HTTPAuth/
Dim bTls As Boolean = True
Dim port As Int = 443
Dim bAutoReconnect As Boolean = True
success = rest.Connect("authenticationtest.com", port, bTls, bAutoReconnect)
If success <> True Then
    Log(rest.LastErrorText)
    Return
End If


'  Send a GET request
Dim responseText As String = rest.FullRequestNoBody("GET", "/HTTPAuth/")
If rest.LastMethodSuccess <> True Then
    Log(rest.LastErrorText)
    Return
End If


'  The start line of an HTTP response, called the status line, contains the following information:
'  
'      The protocol version, usually HTTP/1.1.
'      A status code, indicating success or failure of the request. Common status codes are 200, 404, or 302
'      A status text. A brief, purely informational, textual description of the status code to help a human understand the HTTP message.
'  
'  A typical status line looks like: HTTP/1.1 404 Not Found.

'  The ResponseStatusCode property contains the integer response code:
Log("Response status code = " & rest.ResponseStatusCode)

'  The ResponseStatusText property contains the text (if any) that follows the status code on the status line.
Log("Response status text = " & rest.ResponseStatusText)

'  In this case, the sample output is:
'  
'  Response status code = 401
'  Response status text = Unauthorized
