Google offers developers an API to allow you to work with all the different Google services, including the video service from YouTube. Recent changes to the API allows you to authenticate and interact with all their services. To support these changes, Adobe ColdFusion added a new attribute called multiparttype to the cfhttp tag.
Note: This TechNote is not meant as documentation for using the Google API. You can find complete API documentation on Google's web site.
The cfhttp tag allows for multipart format data with the multipart attribute in cfhttp or by using a header with content type. The issue is that cfhttp tag only uses multipart/form-data while Google and YouTube requires multipart/related. The attached hot fix adds this functionality.
Restart each server updated. The ColdFusion MX hot fix JAR file does not need to be retained after installing it with the ColdFusion Administrator. The file has been copied into the correct location. The hot fix JAR file will appear as a new entry in the System Information list.
The sample code below shows how to authenticate, create the required Atom XML, and upload a video. Upon completion you should see a '201 Created' http code.
All CAPS are the areas that require your Google account and video file data for testing.
