HttpClientFactory扩展类

功能特性：

​ 1.利用IHttpClientFactory创建HttpClient的扩展对象HttpClientExtension；

​ 2.扩展包含两个请求方法：GetAsync和PostAsync，可支持各种类型数据的请求；

​ 3.增加HttpResponseMessage的扩展方法GetRequestLogAsync，用于获取本次请求日志；

​ 4.请求异常不会抛出错误，请求异常（如超时）会返回HttpStatusCode=600，仍然可使用HttpResponseMessage.IsSuccessStatusCode进行判断。

示例：

	public class UnitTest1
    {
        /// <summary>
        /// 测试Get请求
        /// </summary>
        /// <returns></returns>
        [TestMethod]
        public async Task TestGetAsync()
        {
            var httpClient = HttpClientFactoryHelper.CreateClient();

            var resMessage = await httpClient.GetAsync("http://localhost:63447/Home/TestGet?name=test");
            //获取请求日志
            var log = await resMessage.GetRequestLogAsync();
            if (resMessage.IsSuccessStatusCode)
            {
                var content = await resMessage.Content.ReadAsStringAsync();
                Console.WriteLine(content);
            }
            else
            {
                Console.WriteLine(resMessage.ReasonPhrase);
            }
        }
