Getting response header

Question

Used the Flurl to Get response from API.

var response = await url.WithClient(fc)
            .WithHeader("Authorization", requestDto.ApiKey)
            .GetJsonAsync<T>();
dynamic httpResponse = response.Result;

But I cant able to access httpResponse.Headers

How to access response headers while using GetJsonAsync .

Answer 1

You can't get a header from GetJsonAsync<T> because it returns Task<T> instead of raw response. You can call GetAsync and deserialize your payload at next step:

HttpResponseMessage response = await url.GetAsync();

HttpResponseHeaders headers = response.Headers;

FooPayload payload = await response.ReadFromJsonAsync<FooPayload>();

ReadFromJsonAsync is an extention method:

public static async Task<TBody> ReadFromJsonAsync<TBody>(this HttpResponseMessage response)
{
    if (response.Content == null) return default(TBody);

    string content = await response.Content.ReadAsStringAsync();

    return JsonConvert.DeserializeObject<TBody>(content);
}

P.S. This is why I prefer and recommend to use raw HttpClient instead of any third-party high-level client like RestSharp or Flurl.
