C# 写一个http请求工具类

可以使用 C# 自带的 HttpClient 类来实现 HTTP 请求。以下是一个简单的 HTTP 请求工具类示例：

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

namespace HttpUtils
{
    public class HttpUtil
    {
        private static readonly HttpClient client = new HttpClient();

        public static async Task<string> Get(string url)
        {
            HttpResponseMessage response = await client.GetAsync(url);
            response.EnsureSuccessStatusCode();
            return await response.Content.ReadAsStringAsync();
        }

        public static async Task<string> Post(string url, string data)
        {
            HttpContent content = new StringContent(data);
            HttpResponseMessage response = await client.PostAsync(url, content);
            response.EnsureSuccessStatusCode();
            return await response.Content.ReadAsStringAsync();
        }
    }
}

使用示例：

using System;
using System.Threading.Tasks;
using HttpUtils;

namespace Test
{
    class Program
    {
        static async Task Main(string[] args)
        {
            string result = await HttpUtil.Get("https://www.baidu.com");
            Console.WriteLine(result);

            result = await HttpUtil.Post("https://www.example.com/api", "{\"name\":\"John\",\"age\":30}");
            Console.WriteLine(result);
        }
    }
}
