【C#】使用httpclient 实现HTTP请求

        LogHelperUtility.Info(string.Format("[POST]请求参数:{0}", content));
        //默认希望响应使用Json序列化(内容协商机制，我接受json格式的数据)
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        client.Timeout = new TimeSpan(0, 0, timeout);
        // 发送请求

            result["message"] = "接口请求失败";
            return result;

        // 获取数据
