c# - 在 .net 4.5 中努力尝试使 cookie 无法响应 HttpClient

Question

我得到了以下成功运行的代码。我不知道如何从响应中获取 cookie。我的目标是我希望能够在请求中设置 cookie 并从响应中获取 cookie。想法？

private async Task<string> Login(string username, string password)
{
    try
    {
        string url = "http://app.agelessemail.com/account/login/";
        Uri address = new Uri(url);
        var postData = new List<KeyValuePair<string, string>>
        {
            new KeyValuePair<string, string>("username", username),
            new KeyValuePair<string, string>("password ", password)
        };

        HttpContent content = new FormUrlEncodedContent(postData);
        var cookieJar = new CookieContainer();
        var handler = new HttpClientHandler
        {
            CookieContainer = cookieJar,
            UseCookies = true,
            UseDefaultCredentials = false
        };

        var client = new HttpClient(handler)
        {
            BaseAddress = address
        };


        HttpResponseMessage response = await client.PostAsync(url,content);
        response.EnsureSuccessStatusCode();
        string body = await response.Content.ReadAsStringAsync();
        return body;
    }
    catch (Exception e)
    {
        return e.ToString();
    }
}

完整答案如下:

HttpResponseMessage response = await client.PostAsync(url,content);
response.EnsureSuccessStatusCode();

Uri uri = new Uri(UrlBase);
var responseCookies = cookieJar.GetCookies(uri);
foreach (Cookie cookie in responseCookies)
{
    string cookieName = cookie.Name;
    string cookieValue = cookie.Value;
}

要向请求添加 cookie，请在请求之前使用 CookieContainer.Add(uri, cookie) 填充 cookie 容器。发出请求后，cookie 容器将自动填充响应中的所有 cookie。然后您可以调用 GetCookies() 来检索它们。

CookieContainer cookies = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;

HttpClient client = new HttpClient(handler);
HttpResponseMessage response = client.GetAsync("http://google.com").Result;

Uri uri = new Uri("http://google.com");
IEnumerable<Cookie> responseCookies = cookies.GetCookies(uri).Cast<Cookie>();
foreach (Cookie cookie in responseCookies)
    Console.WriteLine(cookie.Name + ": " + cookie.Value);

Console.ReadLine();
