A Few Great Ways to Consume RESTful API in CBy taking a path of Web development, you find yourself in the need of dealing with external APIs Application Programming Interface sooner or later. In this article, my goal will be to make the most comprehensive list of ways to consume RESTful APIs in your C projects and show you how to do that on some simple examples. After reading the article, you will hopefully have more insight which options are available to you and how to choose the right one next time you need to consume a RESTful API. What is RESTful API So, before we start, you might be wondering what API stands for, and what is the RESTful part all about To put things simply, APIs are the layers between software applications. You can send the request to the API, and in return, you get the response from it. APIs hide all the nitty gritty details of the concrete implementation of a software application and expose the interface you should use to communicate with that application. The whole internet is the one big spider web made of APIs. They are used to communicate and relate information between applications. You have an API for pretty much anything out there. You may need to know the status and update a ProgressBar during the file download or use credentials before making the request. Here it is, an example that covers.

Maps, Facebook, Twitter, Instagram, weather portalsRESTful part means that API is implemented in accordance with the principles and rules of the REST Representational State Transfer which is the underlying architectural principle of the web. RESTful APIs in most cases return the plain text, JSON or XML response. Explaining REST in more detail is out of the scope of this article, but my colleague and friend Mladen explained it brilliantly in his article. You should read it, and then read it once more if you are interested in understanding REST. The. NET API Reference documentation has a new home. Visit the. NET API Browser on docs.

There are several ways to consume a RESTful API in C Http. Web. RequestResponse class. Web. Client class. Http. Client class. Rest. Sharp Nu. Get package. Service. Stack Http Utils. Every one of these has pros and cons, so let us go through them and see what they offer. As an example, I will be collecting information about Rest. Sharp repo releases and their publish dates via Git. Hub API. This information is available publicly and you can see how raw JSON response looks here Rest. By The Way Red Hot Chili Peppers Zip. Sharp releases. I will be utilizing the help of the phenomenal Json. NET library to deserialize the response we get. What I expect to get as a result of the next few examples is a deserialized dynamic object for simplicity that contains Rest. Sharp release information. Http. Web. RequestResponse Class. It is the HTTP specific implementation of Web. Request class. It was originally used to deal with HTTP requests, but it was made obsolete and replaced by Web. Client class. It offers fine grained control over every aspect of the request making. As you can imagine, this can be the double edged sword and you can easily end up losing enormous amounts of time fine tuning your requests. On the other hand, this might just be what you need for your specific case. Http. Web. Request class does not block the user interface, which is, I am sure you will agree with this one, pretty important. Http. Web. Response class provides a container for the incoming responses. This is a simple example of how to consume an API using these classes. Http. Web. Request request Http. Web. RequestWeb. Request. Create. https api. Method GET. request. User. Agent Mozilla5.

This class is a wrapper around Http. Web. Request. It simplifies the process by abstracting the details of the Http. Web. Request from the developer. The code is easier to write and you are less likely to make mistakes this way. If you want to write less code, not worry about all the details, and the execution speed is a non factor, consider using Web. Client class. This example should give you a rough idea how much easier it is to use Web. Client compared to the Http. Web. RequestResponse approach. Web. Client. client. Headers. Adduser agent, Mozilla5.

Client class offers a host of other useful methods to make your life easier. You can easily manipulate strings, files or byte arrays using it, and for a price of just a few milliseconds slower than Http. Web. RequestResponse approach. Both the Http. Web. RequestResponse and Web. Client classes are available in the older versions of. NET. Be sure to check out the MSDN if you are interested in what else Web. Client has to offer. Http. Client Class. Http. Client is the new kid on the block, and offers some of the modern. NET functionalities that older libraries lack. For example, you can send multiple requests with the single instance of Http. Client, it is not tied to the particular HTTP server or host, makes use of asyncawait mechanism. You can find out about the five good reasons to use Http. Client in this video Strongly typed headers.

Also, I need to mention one more thing. There is a debate whether Http. Client should be wrapped in using block or statically on the app level. Although it implements IDisposable, it seems that by wrapping it in the using block, you can make your app malfunction and get the Socket. Exception. And as Ankit blogs, the performance test results are much in favor of static initialization of the Http. Client. Be sure to read these blog posts as they can help you be more informed about the correct usage of the Http. Client. And dont forget, being modern, Http. Client is exclusive to the. NET 4. 5, so you might have trouble using it on some legacy projects. Rest. Sharp. Rest. Sharp is the Open. Source alternative to standard. NET libraries and one of the coolest. NET libraries out there. It is available as a Nu. Get package, and there are a few reasons why you should consider trying it out. Like Http. Client, Rest. Sharp is a modern and comprehensive library, easy and pleasant to use, while still having support for older versions of.
