一.先在工程增加 RestClient.cs类 using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Net; using System.Net.Http; using System.Text; using System.Threading.Tasks; using System.Web;

namespace CM2.CentreWin { class RestClient { private System.Net.CookieContainer Cookies = new System.Net.CookieContainer(); private string BaseUri; public RestClient(string baseUri) { this.BaseUri = baseUri; }

#region Get请求 public string Get(string uri) { //先根据用户请求的uri构造请求地址 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; } //internal string Post(string v) //{ // throw new NotImplementedException(); //} #endregion #region Post请求 public string Post(string data, string uri) {

#if true

//先根据用户请求的uri构造请求地址 string serviceUrl = string.Format("{0}/{1}", this.BaseUri, uri); //创建Web访问对象 HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(serviceUrl); //myRequest.ServicePoint.Expect100Continue = false; // 取消100-continue //private System.Net.CookieContainer Cookies = new System.Net.CookieContainer(); //myRequest.CookieContainer = Cookies; //头后面加两个 \r\n //ServicePointManager.Expect100Continue = false;// 取消100-continue //ServicePointManager.UseNagleAlgorithm = true; //ServicePointManager.Expect100Continue = true; //ServicePointManager.CheckCertificateRevocationList = true; //ServicePointManager.DefaultConnectionLimit = ServicePointManager.DefaultPersistentConnectionLimit; //myRequest.ServicePoint.ConnectionLimit = 3000; //myRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.83 Safari/535.11"; //把用户传过来的数据转成“UTF-8”的字节流 byte[] buf = System.Text.Encoding.GetEncoding("UTF-8").GetBytes(data); myRequest.Method = "POST"; myRequest.ContentType = "application/json";//Http内容类型 myRequest.MaximumAutomaticRedirections = 1;//获取或设置请求将跟随的重定向的最大数目。 myRequest.AllowAutoRedirect = true;//获取或设置一个值，该值指示请求是否应跟随重定向响应。 myRequest.SendChunked = false;//获取或设置一个值，该值指示是否将数据分段发送到 Internet 资源。 myRequest.CookieContainer = Cookies;//获取或设置与此请求关联的cookie。 myRequest.UserAgent = "cps";//获取或设置 User-agent HTTP 标头的值 myRequest.Timeout = 18000;//获取或设置请求的超时值。设置请求超时时间，单位为毫秒 myRequest.ContentLength = buf.Length; //发送请求 //Stream stream = myRequest.GetRequestStream(); Stream stream = null; try { stream = myRequest.GetRequestStream(); //获取用于写入请求数据的Stream对象 } catch (Exception ex) { Console.WriteLine(ex); return ""; } stream.Write(buf, 0, buf.Length); stream.Close(); //获取接口返回值 //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;

#endif

} #endregion #region Put请求 public string Put(string data, string uri) { //先根据用户请求的uri构造请求地址 string serviceUrl = string.Format("{0}/{1}", this.BaseUri, uri); //创建Web访问对象 HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(serviceUrl); //把用户传过来的数据转成“UTF-8”的字节流 byte[] buf = System.Text.Encoding.GetEncoding("UTF-8").GetBytes(data); myRequest.Method = "PUT"; myRequest.ContentLength = buf.Length; myRequest.ContentType = "application/json"; myRequest.MaximumAutomaticRedirections = 1; myRequest.AllowAutoRedirect = true; //发送请求 Stream stream = myRequest.GetRequestStream(); stream.Write(buf, 0, buf.Length); stream.Close(); //获取接口返回值 //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; }

#endregion

#region Delete请求 public string Delete(string data, string uri) { //先根据用户请求的uri构造请求地址 string serviceUrl = string.Format(“{0}/{1}”, this.BaseUri, uri); //创建Web访问对象 HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(serviceUrl); //把用户传过来的数据转成“UTF-8”的字节流 byte[] buf = System.Text.Encoding.GetEncoding(“UTF-8”).GetBytes(data);

myRequest.Method = "DELETE"; myRequest.ContentLength = buf.Length; myRequest.ContentType = "application/json"; myRequest.MaximumAutomaticRedirections = 1; myRequest.AllowAutoRedirect = true; //发送请求 Stream stream = myRequest.GetRequestStream(); stream.Write(buf, 0, buf.Length); stream.Close(); //获取接口返回值 //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; }

#endregion

}

二.调用Post发送数据

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");
