View Course Description

Web services drive communication on the web and they have been at the core of modern application architectures for many years. Regardless of what language or platform a developer is using, understanding how web services work is a critical skill. David Gassner starts this course with a definition of web services and explores their history and use in distributed computing. He then explores the transport protocols HTTP and SMTP; messaging formats such as SOAP, ATOM, JSON, and Plain Old XML (POX); and service standards like SOAP toolkits, REST, and OData. Plus, learn how to secure your communications across the web with API keys and other security standards.

Note: The course includes examples of a variety of server- and client-based implementations and coding excerpts in Java, JavaScript, C#, and PHP.

Topics include:
  • What is a web service?
  • Understanding the available transfer protocols and message formats
  • Examining SOAP request and response formats
  • Creating a simple SOAP service in ASP.NET
  • Choosing a SOAP implementation
  • Associating REST actions with HTTP requests
  • Sending RESTful requests
  • Creating OData request URIs
  • Securing web services


(MUSIC). My name is David Gassner and this is Foundations of Programming: Web Services. This course is designed to help you understand the world of web services, explaining different web service standards, web service messaging formats, and available ways of communicating over the web. I'll first define the meaning of the term web service and explore the history of how web services have been used in distributed computing. I'll then break down the components of web service including the transport protocal such as HTTP or SMTP.

And the message format, such as SOAP, ATOM, JSON, or plain old XML. And then I'll review some of the most popular web service standards including SOAP, REST, and OData. Whether you're a software developer or a manager of software development projects or just want to understand the terms used in the web service development world, I hope this course helps you get the information you need.
