Upload Application Specific Data

See more Google Drive Examples

Uploads a text file (application specific data) where the contents of the file are contained in a string variable. Ruby

require 'chilkat'

success = false

success = true

# It 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 application specific data scope.
jsonToken = Chilkat::CkJsonObject.new()
success = jsonToken.LoadFile("qa_data/tokens/googleDriveAppData.json")

gAuth = Chilkat::CkAuthGoogle.new()
gAuth.put_AccessToken(jsonToken.stringOf("access_token"))

rest = Chilkat::CkRest.new()

# Connect using TLS.
bAutoReconnect = true
success = rest.Connect("www.googleapis.com",443,true,bAutoReconnect)

# 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.put_PartSelector("1")
rest.AddHeader("Content-Type","application/json; charset=UTF-8")

json = Chilkat::CkJsonObject.new()
json.put_EmitCompact(false)

json.UpdateString("name","helloWorld.txt")
json.UpdateString("description","A simple text file that says Hello World.")
json.UpdateString("mimeType","text/plain")
# Specifiy the application-specific data folder.
json.UpdateString("parents[0]","appDataFolder")
rest.SetMultipartBodyString(json.emit())

print json.emit() + "\n";

# The JSON looks like this:
# {
#   "name": "helloWorld.txt",
#   "description": "A simple text file that says Hello World.",
#   "mimeType": "text/plain",
#   "parents": [
#     "appDataFolder"
#   ]
# }

# The 2nd part is the file content.
# In this case, we'll upload a simple text file containing "Hello World!"
rest.put_PartSelector("2")
rest.AddHeader("Content-Type","text/plain")

fileContents = "Hello World!"
rest.SetMultipartBodyString(fileContents)

# A successful response will have a status code equal to 200.

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

# Show the full JSON response.
json.put_EmitCompact(false)

# A successful response looks like this:
# {
#   "kind": "drive#file",
#   "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
#   "name": "Untitled",
#   "mimeType": "text/plain"
# }

# Get the fileId:
print "fileId: " + json.stringOf("id") + "\n";
