(VB.NET UWP/WinRT) Get Individual Photo Info

Assuming we have the ID of a Photo, this example demonstrates how to retrieve the photo information and parse the JSON.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

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

'  This example assumes a previously obtained an access token
Dim oauth2 As New Chilkat.OAuth2
oauth2.AccessToken = "FACEBOOK-ACCESS-TOKEN"

Dim rest As New Chilkat.Rest

'  Connect to Facebook...
Dim success As Boolean = Await rest.ConnectAsync("graph.facebook.com",443,True,True)
If (success <> True) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


'  Provide the authentication credentials (i.e. the access key)
rest.SetAuthOAuth2(oauth2)

'  Assumes we've already obtained a Photo ID.
Dim photoId As String = "10210199026347451"

Dim sbPath As New Chilkat.StringBuilder
sbPath.Append("/v2.7/")
sbPath.Append(photoId)

'  Select the fields we want.
'  This example will select many of the possible fields.
'  See https://developers.facebook.com/docs/graph-api/reference/photo/
rest.AddQueryParam("fields","id,album,can_delete,can_tag,from,height,width,images,link,name,name_tags,picture,place,target")

Dim responseJson As String = Await rest.FullRequestNoBodyAsync("GET",sbPath.GetAsString())
If (rest.LastMethodSuccess <> True) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


Dim json As New Chilkat.JsonObject
json.EmitCompact = False
json.Load(responseJson)

'  Show the JSON in human-readable format.
Debug.WriteLine(json.Emit())

'  A sample response is shown below.
'  Demonstrate how to parse values from the JSON.
Debug.WriteLine("Album name: " & json.StringOf("album.name"))
Dim canDelete As Boolean = json.BoolOf("can_delete")
Debug.WriteLine("Can Delete: " & canDelete)
Debug.WriteLine("From Name: " & json.StringOf("from.name"))
Dim height As Integer = json.IntOf("height")
Dim width As Integer = json.IntOf("width")
Debug.WriteLine("Dimensions: " & width & "x" & height)
Debug.WriteLine("First Image Source: " & json.StringOf("images[0].source"))
