即使当AllowAutoRedirect = true时，HttpClient也不重定向

using System;
using System.Net;
using System.Net.Http;

class Program
{
    static void Main()
    {
        HttpClientHandler handler = new HttpClientHandler();
        handler.AllowAutoRedirect = false; // 禁止自动处理重定向

        HttpClient client = new HttpClient(handler);

        HttpResponseMessage response = client.GetAsync("http://example.com").Result;

        if (response.StatusCode == HttpStatusCode.Redirect)
        {
            string redirectUrl = response.Headers.Location.ToString();
            Console.WriteLine("重定向URL: " + redirectUrl);

            // 发送新的请求到重定向URL
            response = client.GetAsync(redirectUrl).Result;
        }

        // 处理最终的响应结果
        Console.WriteLine("最终响应: " + response.StatusCode);
        Console.WriteLine("响应内容: " + response.Content.ReadAsStringAsync().Result);
    }
}
