c# - 使用 httpWebClient 发布后抓取 cookie

Question

我试图在成功 POST 后获取响应中设置的 cookie。如何从结果中获取 cookie？

var baseAddress = new Uri("http://rtchatserver");
            var cookieContainer = new CookieContainer();
            using (var postHandler = new HttpClientHandler() { CookieContainer = cookieContainer })
            using (var client = new HttpClient(postHandler) {BaseAddress = baseAddress})
            {
                var content = new FormUrlEncodedContent(new[]
                {
                    new KeyValuePair<string, string>("UserName", "bar"),
                    new KeyValuePair<string, string>("Password", "bazinga"),
                    new KeyValuePair<string, string>("__RequestVerificationToken", token),
                    new KeyValuePair<string, string>("returnUrl", "http://google.com"),
                });
                cookieContainer.Add(baseAddress, responseCookies.FirstOrDefault());
                var result = client.PostAsync("/account/login", content).Result;

                result.EnsureSuccessStatusCode();
               }

您可以使用 CookieContainer.GetCookies 方法：

var cookies = cookieContainer.GetCookies(new Uri("http://rtchatserver/account/login"));
