    public string Get(string uri)

        string serviceUrl = string.Format("{0}/{1}", this.BaseUri, uri);
        //创建Web访问对  象
        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(serviceUrl);
        //通过Web访问对象获取响应内容
        HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
        //通过响应内容流创建StreamReader对象，因为StreamReader更高级更快
        StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
        //string returnXml = HttpUtility.UrlDecode(reader.ReadToEnd());//如果有编码问题就用这个方法
        string returnXml = reader.ReadToEnd();//利用StreamReader就可以从响应内容从头读到尾
        reader.Close();
        myResponse.Close();
        return returnXml;

二.调用Post发送数据文章来源地址https://www.toymoban.com/news/detail-488130.html

            RestClient client = new RestClient("http://192.168.001.110:8086");
            string result = client.Post("{"day":8,"hour":15,"min":42,"month":5,"sec":15,"week":1,"year":2023}", "api/v1/settimecfg");
