Refit.ApiException Error Handling

Question

How do I get to the content of Refit.ApiException?

Depending on what the inner content is, I want to let the user know how to proceed. So I see that thrown exception has the following content ...

Content "{\"error\":\"invalid_grant\",\"error_description\":\"The user name or password is incorrect.\"}"

The question is, how do I access that?

Answer 1

You can add one catch block for ApiException. and you can get content from this catch block. See below:

catch (ApiException ex)
{
    var content = ex.GetContentAs<Dictionary<String, String>>();
    Debug.WriteLine(ex.Message);
}

Answer 2

Going through the RestService class https://github.com/paulcbetts/refit/blob/master/Refit/RestService.cs

figured out I could use the GetContentAs method

So just did this..

((Refit.ApiException)ex).GetContentAs<Dictionary<String, String>>()) 

to parse out the key value content.

Answer 3

As an extra heads-up:

GetContentAs<T>(); is now deprecated.

Use GetContentAsAsync<T>(); instead.
