How to read cookies from HttpResponseMessage?

Question

This is my recent code:

HttpClient authClient = new HttpClient(); authClient.BaseAddress = new Uri("http://localhost:4999/test_db/_session"); authClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));  var user = new LoginUserSecretModel {     name = userKey,     password = loginData.Password, }; HttpResponseMessage authenticationResponse = authClient.PostAsJsonAsync("", user).Result; 

Answer 1

The issue I have with many of the answers here is that using CookieContainer uses short-lived HttpClient objects which is not recommended.

Instead, you can simply read the "Set-Cookie" header from the response:

// httpClient is long-lived and comes from a IHttpClientFactory HttpResponseMessage response = await httpClient.GetAsync(uri); IEnumerable<string> cookies = response.Headers.SingleOrDefault(header => header.Key == "Set-Cookie")?.Value;
