跨服务调用get的接口时，添加了token，仍然提示Response status code does not indicate success: 401 (Unauthorized)，经过调试，发现原因是未指定token的认证方式
原代码：

            //HttpClient client = new HttpClient(new HttpClientHandler() { UseCookies = false });

            if (header != null)
            {
                //client.DefaultRequestHeaders.Clear();
                foreach (var item in header)
                {
                    Client.DefaultRequestHeaders.Add(item.Key, item.Value);
                }
            }
            if (!string.IsNullOrEmpty(token))
            {
                Client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue(token);
            }
            try
            {
                HttpResponseMessage response = await Client.GetAsync(url);
                response.EnsureSuccessStatusCode();
                string responseBody = await response.Content.ReadAsStringAsync();
                return responseBody;
            }
            catch
            {
                throw;
            }

需指定token的认证方式，本例子token是Bearer，因此Client.DefaultRequestHeaders.Authorization的值修改为：

            //HttpClient client = new HttpClient(new HttpClientHandler() { UseCookies = false });

            if (header != null)
            {
                //client.DefaultRequestHeaders.Clear();
                foreach (var item in header)
                {
                    Client.DefaultRequestHeaders.Add(item.Key, item.Value);
                }
            }
            if (!string.IsNullOrEmpty(token))
            {
                Client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token);
            }
            try
            {
                HttpResponseMessage response = await Client.GetAsync(url);
                response.EnsureSuccessStatusCode();
                string responseBody = await response.Content.ReadAsStringAsync();
                return responseBody;
            }
            catch
            {
                throw;
            }

再次调用，成功！
