We have learnt how to apply CORS in various services across the web. Let us recollect each one of them. We started with an understanding of how to use CORS with Amazon S3, Google Cloud Storage, and Windows Azure.
Then, we learned about how to use CORS in the Google API Client
library for JavaScript to interact with Google products and services. We also discussed how to use CORS with IBM Cloudant's data storage service.
Finally, we discussed how to use CORS so that it interacts with files stored in Box and Dropbox. To interact with Google Drive files, use the Google API Client
library for JavaScript or the Google Drive SDK.
