RESTFUL PHP WEB SERVICES SAMISA ABEYSINGHE PDF

The problem is that I do not know and could not find good information on how to implement the certificate mechanics, both server side in the php web service, and client side properly. Apache, Nginx, etc. Search the web for "ssl tutorial" for your particular HTTP server? To make it easier, I will show you a simple example and how things work with the code below. Feel free to use only the parts you need which should be pretty straight forward. The way you have currently created your app works just fine with the server side sessions.

The book succeeds in providing simple steps and examples of creating and consuming web services, but falls short on REST architectural concepts and design principles. The book starts with a very brief introduction to the principles of REST, and rapidly moves on to a discussion of PHP tools frameworks. Some of the information in the introduction is confusing.

This does sound a little odd — resources can have multiple representations, for example, for different requested content types. Representations should reflect resource state, not application state. The author chooses realistic examples for code samples, such as Flickr and Yahoo Maps clients. The last example given is quite cool — using earthquake latitudes and longitudes from an Australian government site to plot points on Yahoo maps.

The example code is generally simple and easy to follow. However, it would have been nice to see some sort of separation between view and data access logic. The following chapter is a worked example of building RESTful services for a library lending books.

It is a good example, and becomes the basis for most future chapters. Using links between resources, rather than just relying on known URLs would also benefit the design. Later chapters cover alternative frameworks such as Zend and WSO2 using the library lending system as an example for code samples. These chapters are useful as they give an idea how the frameworks look when put in practice. It does look as though PHP and frameworks still have significant limitations around routing flexibility from the examples eg, the.

There is also a chapter on debugging with tips around tools and troubleshooting XML parsing issues. The writing style is generally clear and easy to read. Overall, I would recommend this book to people wanting to write simple URI template based web services or clients in PHP, and also to people interested in getting an overview of libraries and frameworks currently available in the PHP ecosystem.
