本文介绍了如何在C#中封装异步的HTTP请求接口，包括Get和Post两种方式，旨在简化调用流程并提供日后查阅的便利。

说明：

因为经常需要调用Http接口，所以封装了一个类，一是为了方便调用Http接口、二是记录一下方便以后忘了的时候可以看一下；仅有Get、Post两种异步请求接口的方式。

Get、Post方法封装

        private HttpClient httpClient;

        public HttpUtil()
        {
            HttpClientHandler handler = new HttpClientHandler() { UseCookies = true };
            httpClient = new HttpClient(handler);
            httpClient.Timeout = new TimeSpan(0, 0, 0, 300); //超时时间             
        }

        /// <summary>
        /// 异步Get请求
        /// </summary>
        /// <param name="url"></param>
        /// <param name="isDialog"></param>
        /// <returns></returns>
        public async Task<string> Get(string url)
        {
            HttpResponseMessage response;
            try
            {

                response = await httpClient.GetAsync(new Uri(url));
                Console.WriteLine("URL:" + url);
            }
            catch
            {
                return null;
            }
            string result = await response.Content.ReadAsStringAsync();

            Console.WriteLine("result-->"+result);
            if (!result.Contains("status"))
            {
                return null;
            }
            return result;
        }
        /// <summary>
        /// 异步Post请求
