C#使用HttpWebRequest发送请求

使用HttpWebRequest可以帮助我们发送web请求

        //发送post请求
        public string SendPostReq(string param)
        {
            string content = "";

            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(Url);
            request.Method = "Post";
            request.ContentType = "application/json";

            //加basic认证
            request.Headers.Add("Authorization", "Basic " + GetAuthString());
            //请求参数
            byte[] bytes = Encoding.UTF8.GetBytes(param);
            #region 写入参数
            request.ContentLength = bytes.Length;
            Stream requestStream = request.GetRequestStream();
            requestStream.Write(bytes, 0, bytes.Length);
            requestStream.Close();
            #endregion

            //读取请求结果
            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            {
                using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                {
                    content = reader.ReadToEnd();
                }
            }
            return content;
        }

        //返回结果是否成功
        public bool IsSuccess(string content)
        {
            JObject jo = JObject.Parse(content);
            if (jo["status"].ToString() == "1")
            {
                return true;
            }
            return false;
        }

其中，Url为自己配置的请求地址，param为json字符串，我在里面还加入Authentication认证，内容使用base64编码

在接收方如何判断呢

            string authHeader = this.Request.Headers["Authorization"];
            string res = "";
            if (!string.IsNullOrEmpty(authHeader))
            {
                string token = authHeader.Substring("Basic ".Length).Trim();
                res = Encoding.UTF8.GetString(Convert.FromBase64String(token));
            }

res即为认证的内容
