如何使用C# .NET框架在HTTP请求中添加2个身份验证头

using System;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;

class Program
{
    static void Main()
    {
        HttpClient client = new HttpClient();

        string username = "your_username";
        string password = "your_password";
        string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(username + ":" + password));

        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials);
        client.DefaultRequestHeaders.Add("X-Auth-Token", "your_token");

        // 发送HTTP请求
        HttpResponseMessage response = client.GetAsync("http://example.com/api/resource").Result;

        // 处理响应
        if (response.IsSuccessStatusCode)
        {
            string responseBody = response.Content.ReadAsStringAsync().Result;
            Console.WriteLine(responseBody);
        }
        else
        {
            Console.WriteLine("请求失败，状态码：" + response.StatusCode);
        }
    }
}
