(VB.NET UWP/WinRT) VoiceBase -- Hello World (Get the Media Collection Listing)

This example serves to both verify that your Bearer Token is valid by retrieving JSON that contains information about your media collection.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads Chilkat for the Universal Windows Platform (UWP)

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

' Insert your Bearer token here:
Dim accessToken As String = "VOICEBASE_TOKEN"

Dim http As New Chilkat.Http

' Add the access (bearer) token to the request, which is a header
' having the following format:
' Authorization: Bearer <userAccessToken>
Dim sbAuth As New Chilkat.StringBuilder
sbAuth.Append("Bearer ")
sbAuth.Append(accessToken)
http.SetRequestHeader("Authorization",sbAuth.GetAsString())

Dim strJson As String = Await http.QuickGetStrAsync("https://apis.voicebase.com/v2-beta/media")
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' The response should be JSON, even if an error.
Dim json As New Chilkat.JsonObject
json.Load(strJson)
json.EmitCompact = False

Debug.WriteLine("Response status code = " & http.LastStatus)

If (http.LastStatus <> 200) Then
    Debug.WriteLine(json.Emit())
    Debug.WriteLine("Failed")
    Exit Sub
End If


' See the sample JSON response below..

' Iterate over the JSON like this:
Dim dt As New Chilkat.CkDateTime
Dim mediaCount As Integer = json.SizeOfArray("media")
Dim i As Integer = 0
While i < mediaCount
    json.I = i

    Debug.WriteLine("-- " & i & " --")
    Debug.WriteLine("  mediaId: " & json.StringOf("media[i].mediaId"))
    Debug.WriteLine("  status: " & json.StringOf("media[i].status"))
    Debug.WriteLine("  contentType: " & json.StringOf("media[i].metadata.contentType"))
    Debug.WriteLine("  milliseconds: " & json.StringOf("media[i].metadata.length.milliseconds"))
    Debug.WriteLine("  descriptive: " & json.StringOf("media[i].metadata.length.descriptive"))
    Dim dateCreated As String = json.StringOf("media[i].dateCreated")
    dt.SetFromTimestamp(dateCreated)

    Dim localTime As Boolean = True
    Dim dtObj As Chilkat.DtObj = dt.GetDtObj(localTime)
    Debug.WriteLine("  " & dtObj.Month & "/" & dtObj.Day & "  " & dtObj.Hour & ":" & dtObj.Minute)


    i = i + 1
End While
Debug.WriteLine("Finished.")
