To easily understand this chapter, you should have beginner knowledge of HTTP. The required concepts are as follows:
- Uniform Resource Identifiers (URIs)
- Methods (such as GET)
- Headers
- Body
- Content type (such as plain/text)
- Status code (such as Not Found=404)
Before starting the projects in this chapter, a generic HTTP client should be installed on your computer. The tool used in the examples is the command-line tool curl, freely available for many operating systems. The official download page is https://curl.haxx.se/download.html. In particular, the page for Microsoft Windows is https://curl.haxx.se/windows/.
Alternatively, you can use one of the several good, free web-browser utilities, such as Advanced REST Client for Chrome, or RESTED and RESTer for Firefox.
