See more REST Examples

Demonstrates a file upload to Google Drive where the contents of the file are contained in a string variable. Ruby

require 'chilkat'

success = false

# This example will upload a file to Google Drive.
success = true

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

gAuth = Chilkat::CkAuthGoogle.new()
gAuth.put_Scope("https://www.googleapis.com/auth/drive")
gAuth.put_SubEmailAddress("some.user@example.com")
gAuth.put_ExpireNumSeconds(3600)

# Obtain an access token as shown in one of the following examples:
# See Get Access Token using a Service Account JSON Key
# See Get Access Token using a P12 File

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 key)
success = rest.SetAuthGoogle(gAuth)

# A multipart upload to Google Drive needs a multipart/related Content-Type
success = 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")
success = rest.AddHeader("Content-Type","application/json; charset=UTF-8")

json = Chilkat::CkJsonObject.new()
success = json.AddStringAt(-1,"title","helloWorld.txt")
success = json.AddStringAt(-1,"description","A simple text file that says Hello World.")
success = json.AddStringAt(-1,"mimeType","text/plain")
success = rest.SetMultipartBodyString(json.emit())

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

# POST https://www.googleapis.com/upload/drive/v2/files
jsonResponse = rest.fullRequestMultipart("POST","/upload/drive/v2/files?uploadType=multipart")
if (rest.get_LastMethodSuccess() != true)
    print rest.lastErrorText() + "\n";
    exit
end

# Show the JSON response.
print "Response Status Code: " + rest.get_ResponseStatusCode().to_s() + "\n";
print "Json Response: " + jsonResponse + "\n";
