C# HTTP RAW 传输

最近做项目开发需要上传用户行为数据，采用C#来上传数据

使用了HttpWebRequest 来实现

传输方式采用的是POST的方式

内容格式采用application/json

具体实现的代码如下:

public static string HttpPostRaw(string url, string data)
        {
            string value = "";
            try
            {
                HttpWebRequest reqest = (HttpWebRequest)WebRequest.Create(url);
                reqest.Method = "POST";
                reqest.ContentType = "application/json";
                Stream stream = reqest.GetRequestStream();
                byte[] bs = System.Text.Encoding.UTF8.GetBytes(data);
                stream.Write(bs, 0, bs.Length);
                stream.Flush();
                stream.Close();
                HttpWebResponse response = (HttpWebResponse)reqest.GetResponse();
                StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
                value = sr.ReadToEnd();
                response.Close();
                return value;
            }
            catch (Exception ex)
            {
                error = ex.ToString();
                return "";
            }
        }
