如何在c#,ASP .NET中修改请求标头

using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace ModifyRequestHeader
{
    class Program
    {
        static async Task Main(string[] args)
        {
            using var httpClient = new HttpClient();

            // 添加请求标头
            httpClient.DefaultRequestHeaders.Add("HeaderName", "HeaderValue");

            // 修改请求标头
            httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", "YourToken");

            // 发送请求
            var response = await httpClient.GetAsync("https://your-api-url.com");

            // 处理响应
            if (response.IsSuccessStatusCode)
            {
                var responseContent = await response.Content.ReadAsStringAsync();
                Console.WriteLine("Response content: " + responseContent);
            }
            else
            {
                Console.WriteLine("Error: " + response.StatusCode);
            }
        }
    }
}
