require 'chilkat'

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

# Assume we've previously obtained an access token and saved it to a JSON file..
jsonToken = Chilkat::CkJsonObject.new()
success = jsonToken.LoadFile("qa_data/tokens/twitter.json")

http = Chilkat::CkHttp.new()

# Provide the OAuth 1.0a credentials:
http.put_OAuth1(true)
http.put_OAuthConsumerKey("TWITTER_CONSUMER_KEY")
http.put_OAuthConsumerSecret("TWITTER_CONSUMER_SECRET")
http.put_OAuthToken(jsonToken.stringOf("oauth_token"))
http.put_OAuthTokenSecret(jsonToken.stringOf("oauth_token_secret"))

req = Chilkat::CkHttpRequest.new()
req.put_HttpVerb("POST")
req.put_ContentType("multipart/form-data")
req.put_Path("/1.1/media/upload.json")

req.AddHeader("Expect","100-continue")

# Add a JPEG image file to the upload.
fac = Chilkat::CkFileAccess.new()
jpgBytes = Chilkat::CkByteData.new()
success = fac.ReadEntireFile("qa_data/jpg/starfish.jpg",jpgBytes)
req.AddBytesForUpload("media","starfish.jpg",jpgBytes)

# resp is a CkHttpResponse
resp = http.SynchronousRequest("upload.twitter.com",443,true,req)
if (http.get_LastMethodSuccess() != true)
    print http.lastErrorText() + "\n";
    exit
end

jsonResponse = Chilkat::CkJsonObject.new()
jsonResponse.put_EmitCompact(false)
jsonResponse.Load(resp.bodyStr())

if (resp.get_StatusCode() != 200)
    print jsonResponse.emit() + "\n";
    exit
end

# Show the successful response:
print jsonResponse.emit() + "\n";
print "Success." + "\n";

# A successful JSON response looks like this:

# 	{
# 	  "media_id": 793137045996646400,
# 	  "media_id_string": "793137045996646400",
# 	  "size": 6229,
# 	  "expires_after_secs": 86400,
# 	  "image": {
# 	    "image_type": "image\/jpeg",
# 	    "w": 120,
# 	    "h": 120
# 	  }
# 	}
# 

# Get the information from the JSON:
print "media_id_string = " + jsonResponse.stringOf("media_id_string") + "\n";
print "size = " + jsonResponse.IntOf("size").to_s() + "\n";
print "image_type = " + jsonResponse.stringOf("image.image_type") + "\n";
print "height/width = " + jsonResponse.IntOf("image.w").to_s() + "," + jsonResponse.IntOf("image.h").to_s() + "\n";
