ODataController - 406
So I’m working on a project that returns some entities from an OData endpoint, I wanted to remove the unnecessary parts of my entities so I created some DTO’s (which in itself is a good idea btw). The screenshot below shows the changes, I’m now returning a TimeSheetDto list (previously just a TimeSheet list) and I’m just projecting (using automapper) the Timesheets from my database into these DTO’s .
However when I test said entities I see nothing come back in my browser, nada,zilch,zippo… so what is happening?
Well I fired up fiddler and saw that I was getting a HTTP status code of 406, but why?
It worked before and I changed nothing…. oh wait!….
Configure OData entities
You know that message that gets scaffolded with new OData end points!? We’ll it explicitly tells us what entities are to be considered, so with a quick addition of my Dto Suffix in my OData config I’m back in action.
So in my previous post I show you how to auth with a bearer token against WebApi2 with the OWIN middleware using a HttpClient. Next up I show you how to do the same with AngularJS.
AngularJS
True to form I’m not going to write a big long blog post on this topic, there are many others that are better than mine. There are even a nice few github hosted solutions you can grab for yourself.
I ended up picking the first post I saw, http://www.codeproject.com/Articles/742532/Using-Web-API-Individual-User-Account-plus-CORS-En
Now lets ignore the CORS part for starters (have banged my head against the walls many times over that). In order to get this working with the latest and greatest web api as of this post you’ll need two little tweaks
1) Relative URL
The author posts the following code
You’ll need to change the baseUrl to an empty string, if you leave it this way (even when correcting the port) you’ll end up in a CORS situation and you’ll see the browser send an OPTIONS request which you don’t want. (in fairness the author was showing CORS working so there is nothing wrong with his/her post).
2) Token Payload
The important part is that i create a new object ‘data’ and this contains the querystring for the POST body, in the $http call, I then pass data rather than userData like the codeproject article shows.
That’s it, you should now be up and running.
Hi all, I know I promised my next post was going to be more Azure but I encountered a little task that took me a while to get working, the scenario was that I wanted to make a call to my WebAPI (MVC5) service using a C# HttpClient, the problem was that the resource I wished to access had the AuthorizeAttribute set
Now there’s a few ways to skin a cat but in the presence of the default Token Authorization one needs to first get a token and then use this token in subsequent requests. There is some good documentation using fiddler here: http://www.asp.net/web-api/overview/security/individual-accounts-in-web-api, however, there was not a lot of information on how to do this with HttpClient against Katana/Owin/MVC5, rather this information was not available in one specific place.
How
The first request gets the token and then this token is used as the Bearer for further requests.
