So I'm getting started learning Rails. Now that Rails 3 is out, I want to stick to learning the Rails 3 way of doing things. One of the things I want to learn how to do is how to consume web services / work with third party REST APIs / create "mashup" applications. I've only done minimal work like this with PHP and pre-built libraries.
Can someone please lead me to some resources, best practices, or give me a quick 101 lesson on how to start working with these types of APIs? What gems should I use? Some sample code to get me started would be much appreciated.
Update: I am specifically trying to use the Google Books API (non-authenticated). Since there is no client library for this API, I'm wondering how other Ruby/Rails developers are working with APIs that don't come with their own Ruby library. That's why I'm looking for a more generic solution to working with "fill in the blank" API.
Update: After some research, I noticed the Net::HTTP library. All the tutorials that talked about it were fairly old. Is this still the best library to use for consuming RESTful web services? Or is there a newer Gem that makes this easier? I just want to know which gem/library I should use, and how to work with the XML/JSON result that is returned.
Update: This presentation was really helpful. It mentions a bunch of different libraries and shows examples of some of the libraries mentioned below: http://www.slideshare.net/pengwynn/json-and-the-apinauts
我推荐使用Nokogiri的REST: http: //railscasts.com/episodes/190-screen-scraping-with-nokogiri Nokogiri也适用于xml,而不仅仅是HTML。
Weary is a really neat DSL for consuming RESTful services.
Clearly inspired by HTTParty but a bit newer and a bit more concise.
