Summary

In this chapter, you've been shown how you can use HTTP to publish sensor data and interact with devices on the internet. You've learned the basic principles of the HTTP protocol and how to publish resources and interact with them using HTTP. You've also learned to separate resource, state and representations of data, which is a requirement for making RESTful web services. In the next chapter, we will delve deeper into the world of the HTTP protocol by showing you how human interfaces can be built to interact with the machine-based web services created in this chapter.
