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

# This example uses a previously obtained access token having permission for the 
# Google Drive scope.

$gAuth = New-Object Chilkat.AuthGoogle
$gAuth.AccessToken = "GOOGLE-DRIVE-ACCESS-TOKEN"

$rest = New-Object Chilkat.Rest

# Connect using TLS.

# Provide the authentication credentials (i.e. the access token)
$rest.SetAuthGoogle($gAuth)

# -------------------------------------------------------------------------
# A multipart upload to Google Drive needs a multipart/related Content-Type
$rest.AddHeader("Content-Type","multipart/related")

# Specify each part of the request.

# The 1st part is JSON with information about the file.
$rest.PartSelector = "1"
$rest.AddHeader("Content-Type","application/json; charset=UTF-8")

# Construct the JSON that will contain the metadata about the file data to be uploaded...
$json = New-Object Chilkat.JsonObject
$json.AppendString("name","hedgehogs.jpg")
$json.AppendString("description","A cute photo of two hedgehogs.")
$json.AppendString("mimeType","image/jpeg")

# To place the file in a folder, we must add a parents[] array to the JSON
# and add the folder ID.  
# In a previous example (see Build Local Metadata Cache
# we built a local cache to make it easy to lookup file IDs given a file path.
# Let's find the file ID for the folder "testFolder/abc/123"
$gdCache = New-Object Chilkat.Cache
$gdCache.Level = 0
$gdCache.AddRoot("C:/ckCache/googleDrive")

$folderId = $gdCache.FetchText("testFolder/abc/123")
if ($gdCache.LastMethodSuccess -ne $true) {
    $("Filepath not found in cache.")
    exit
}

$parents = $json.AppendArray("parents")
$parents.AddStringAt(-1,$folderId)

$rest.SetMultipartBodyString($json.Emit())

# The 2nd part is the file content, which will contain the binary image data.
$rest.PartSelector = "2"
$rest.AddHeader("Content-Type","image/jpeg")

$fac = New-Object Chilkat.FileAccess

# Read a JPG file from the local filesystem.
$jpgBytes = $fac.ReadEntireFile("qa_data/jpg/hedgehogs.jpg")

# Add the bytes to our upload
$rest.SetMultipartBodyBinary($jpgBytes)

$jsonResponse = $rest.FullRequestMultipart("POST","/upload/drive/v3/files?uploadType=multipart")
if ($rest.LastMethodSuccess -ne $true) {

    exit
}

# A successful response will have a status code equal to 200.
if ($rest.ResponseStatusCode -ne 200) {
    $("response status code = " + $rest.ResponseStatusCode)
    $("response status text = " + $rest.ResponseStatusText)

    exit
}

# Show the JSON response.
$json.Load($jsonResponse)

# Show the full JSON response.
$json.EmitCompact = $false

# A successful response looks like this:

#   "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
#   "name": "hedgehogs.jpg",
#   "mimeType": "image/jpeg"
# }

# Get the fileId:
$("fileId: " + $json.StringOf("id"))
