(VB.NET) Xero Upload File (Files API)

Demonstrates how to upload a file to a Xero folder.

Note: This example requires Chilkat v9.5.0.64 or greater.

Chilkat .NET Downloads

Chilkat .NET Assemblies

Chilkat for .NET Core

Chilkat for Mono

' Note: Requires Chilkat v9.5.0.64 or greater.

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

Dim rest As New Chilkat.Rest
Dim success As Boolean


' Before sending REST API calls, the REST object needs to be
' initialized for OAuth1.
' See Xero 2-Legged OAuth1 Setup for sample code.

' Assuming the REST object's OAuth1 authenticator is setup, and the initial
' connection was made, we may now send REST HTTP requests..

' --------------------------------------------------------------
' This example will upload a file to a folder using the Xero FILES API

Dim folderID As String = "0ffca059-f2f1-4271-8de9-4b87c8c2c638"
' This JPG image can be downloaded from https://www.chilkatsoft.com/syncedImages/penguins.jpg
Dim filename As String = "penguins.jpg"

Dim sbPath As New Chilkat.StringBuilder
sbPath.Append("/files.xro/1.0/Files/{FolderId}")
Dim numReplaced As Integer = sbPath.Replace("{FolderId}",folderID)

rest.AddHeader("Content-Type","image/jpeg")

' Load the JPG image from a file.
Dim jpgData As New Chilkat.BinData
success = jpgData.LoadFile("qa_data/jpg/penguins.jpg")

' We could alternatively get it from a URL like this:
Dim jpgDataFromWeb As New Chilkat.BinData
Dim http As New Chilkat.Http
success = http.QuickGetBd("https://www.chilkatsoft.com/syncedImages/penguins.jpg",jpgDataFromWeb)
If (success <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If

' 
' Put the file data in the 1st sub-part in the multipart/form-data request we'll be sending.
rest.PartSelector = "1"
rest.SetMultipartBodyBd(jpgData)

' Set request headers in the 1st subpart (as indicated by the PartSelector)
rest.AddHeader("Content-Type","image/jpeg")
rest.AddHeader("Content-Disposition","multipart/form-data; name=Xero; filename=penguins.jpg")

' Restore the PartSelector to an empty string.
rest.PartSelector = ""

rest.AddHeader("Content-Type","multipart/form-data")

' Upload with a multipart/form-data POST
Dim responseJson As String = rest.FullRequestMultipart("POST",sbPath.GetAsString())
If (rest.LastMethodSuccess <> True) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


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

' A 201 response is expected for actual success.
' The Xero documentation doesn't explicitly state it, but that's what we've found in testing.
' To be safe, we'll check for either 200 or 201.
If ((rest.ResponseStatusCode <> 200) And (rest.ResponseStatusCode <> 201)) Then
    Debug.WriteLine(json.Emit())
    Exit Sub
End If


' Examine the JSON response
Debug.WriteLine(json.Emit())

' A successful response looks like this:
