将cookies从当前HttpContext传输到新创建的HttpClient请求的简单方法

// 获取当前HttpContext中的cookies
var cookies = HttpContext.Request.Cookies;

// 创建一个HttpClientHandler并设置CookieContainer属性
var handler = new HttpClientHandler();
handler.CookieContainer = new CookieContainer();

// 将HttpContext中的cookies添加到CookieContainer中
foreach (var cookie in cookies)
{
    handler.CookieContainer.Add(new Uri("https://example.com"), new Cookie(cookie.Key, cookie.Value));
}

// 创建一个新的HttpClient并使用上面创建的HttpClientHandler
var client = new HttpClient(handler);

// 发送请求
var response = await client.GetAsync("https://example.com/api");

// 处理响应
var content = await response.Content.ReadAsStringAsync();
