On an existing host I've added Web API Models & Controllers. I've added the following four:
- Products
- Orders
- Categories
- Users
When someone accesses the localhost:port\api\products, it returns all the products in JSON format.
The Create, Update and Delete statements are completely disabled, so we are only able to use GET-requests on the API (so either \api\products for a list of all products or api\products\# for a single products with id #).
Because the other CRUD's aren't used, there isn't a lot of security that should be added to the Web API, except for one thing: The Users
These will also return emails and such, which would be better to keep private and unreadable without the proper authorization (without entire log-in pages, but a way to authenticate yourself when accessing the Web API in for example Android HttpGetRequests).
So, the question: How should I add authorization for only the UsersController accessed by the Web API.
And, how can I encrypt the JSON in C# and decrypt it in Android again. If this second part is too big to answer I'll make a new question later on, my main focus is the low-end [<- without log-in pages, so built in into the GET-request] authorization of the Web API's GET-request for Users.
Edit 1: I did found this link where a new project is made with Authorization Changed to Individual Users. I also see that the user is registered and then logged in with POST and GET requests.
The following questions came into mind when reading through this link:
- How to change the Web API's Authorization to Individual Users on an existing project?
- Our authorization is done through OAuth (mainly Google-account) with our work e-mail address. I guess it's not possible / easy to authorize in the same way as in the link with a Google-account on Web API GET-requests.
Edit 2: After using the first link provided by Vladimir Gondarev I've added the [Authorize] to both the Get methods in the UsersController. In my project everything else was already used before, like a class that uses the AuthorizeAttribute, so just adding the [Authorize] was already enough for the first step. Now in the browser I get an unauthorized (JSON) back when I'm not logged in, which is good.
The next step would be to add the OAuth-authorization to the Android app, but that is an entire new problem / question that I will look into first before asking a new stackoverflow-question.
