NASA requires a valid API key to access their free pictures of the day service. Register for an API Key from NASA (It's Free)
In a terminal or command window, change to a directory where you will store the tutorial, and clone this public git repository:

Download API Proxy Tutorial Source CodeĪll tutorial source code is available on github.
The tutorial should run properly on windows, mac, or linux environments. To get started, you need to download the tutorial source code, get some keys, and ensure your development tools are in place. These benefits increase as multiple API services are proxied through the same server. By establishing trust between client and proxy server, the attestation service offers a quick rejection filter to drop invalid traffic before burdening the actual API servers. The proxy service itself is stateless which brings load balancing, failure recovery, and other scalability benefits. From a manageability standpoint, since the secret is no longer on the client, the decision can be made to improve security without requiring any change to the installed base of clients. If the secret is somehow compromised, it can be replaced at the proxy server with a fresh secret. Since we've removed the secret from the client, it's no longer there to be stolen. We've added an extra hop between client and service, but it does offer significant benefits. We'll use the NASA service as an example of an API which would be typically called from a mobile client app. This approach is discussed in detail in the Mobile API Security articles. We also add an attestation service to establish trust between client and the new proxy server. Unfortunately, for a secret held on a mobile app, it's not a question of if it will be stolen but when it will be stolen and with how much effort.īy introducing an API key proxy server between the client app and its 3rd party services, we can remove the API keys from an insecure mobile client and place them on a more secure proxy server. Why Add an API Proxy?Īpps of any complexity will make extensive use of multiple 3rd party services via their public APIs which means handling and safeguarding many secret API keys. To access the service, the API requires a registered API key which will be initially stored in the client app. The app uses NASA's picture of the day API to retrieve images and descriptions.

Clicking on an image brings up a detailed screen containing the full image and its description. The initial screen displays a gallery of recent NASA picture of the day images.

The Astropiks mobile app is a relatively simple networked Android client with two main screens. All code is provided, so it should be possible to follow along even if you have limited experience in these environments. I assume that you have some very basic familiarity with Android and can read Java and Javascript.
For demonstration purposes, both an Android client emulation and the node server can be run together on a single laptop. In addition to improved API security, this approach offers some benefits in manageability and scalability.ĭuring the tutorial, you will modify an Android client and Node.js proxy server. An API Proxy introduced between your client and the picture service will remove the need for storing and protecting the API key on the client. In this tutorial, you will work with a simple photo client which uses an API key to access the NASA picture of the day service. Image Credit: NASA, ESA, Hubble)ĪPI keys and other secrets poorly hidden inside mobile apps are a common source of mobile insecurity. And that's it, no extra bells or whistles.(UGC 12591: The Fastest Rotating Galaxy Known. If it is a video, a play button will overlay the image and bring you to watch the video when you click it. There is a button at the top that you can use to look at the original article and a download button to get to the high definition image. It will probably be something different for you as you will be opening this up on a different day. Today's entry looks like it is a picture of Comet 21P between the Rosette and Cone Nebulas. Sometimes it will be a picture and other times it will be a link to a video online.

It connects to NASA's APOD API to download and show you a fascinating picture of the universe with a brief explanation written by a professional astronomer for that day. This application, as the name might elude to, is a simple Astronomy Picture of the Day, or APOD, viewing application. I have an emulator running that I will deploy it to. Once the project is loaded, go ahead and run it on a device. I have extracted it to my desktop, so I will navigate there to open it up. Let's open up the sample project in Android Studio and take a look at what it's designed to do. You can follow along with this project or use your own if you prefer. Included in the Exercise Files for this course is a sample project that I will be using throughout the next few chapters.
