如何在C#中使用HttpClient存储cookies？

HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = new CookieContainer();
HttpClient client = new HttpClient(handler);

client.CookieContainer = handler.CookieContainer;

// 获取所有cookies
CookieCollection cookies = handler.CookieContainer.GetCookies(new Uri("http://example.com"));

// 获取特定名称的cookie
Cookie cookie = handler.CookieContainer.GetCookies(new Uri("http://example.com"))["cookieName"];

// 添加cookie
handler.CookieContainer.Add(new Uri("http://example.com"), new Cookie("cookieName", "cookieValue"));

// 删除cookie
handler.CookieContainer.GetCookies(new Uri("http://example.com")).Remove("cookieName");

client.DefaultRequestHeaders.Add("Cookie", "cookieName=cookieValue");
