如何做一个HTTP PUT请求？

在C＃中编写一个PUT请求的最好方法是什么？

该请求还必须发送URI中不存在的对象。

Answer 1

using(var client = new System.Net.WebClient()) { client.UploadData(address,"PUT",data); } 

Answer 2

我的最后办法：

  public void PutObject(string postUrl, object payload) { var request = (HttpWebRequest)WebRequest.Create(postUrl); request.Method = "PUT"; request.ContentType = "application/xml"; if (payload !=null) { request.ContentLength = Size(payload); Stream dataStream = request.GetRequestStream(); Serialize(dataStream,payload); dataStream.Close(); } HttpWebResponse response = (HttpWebResponse)request.GetResponse(); string returnString = response.StatusCode.ToString(); } public void Serialize(Stream output, object input) { var ser = new DataContractSerializer(input.GetType()); ser.WriteObject(output, input); } 

Answer 3

 protected void UpdateButton_Click(object sender, EventArgs e) { var values = string.Format("Name={0}&Family={1}&Id={2}", NameToUpdateTextBox.Text, FamilyToUpdateTextBox.Text, IdToUpdateTextBox.Text); var bytes = Encoding.ASCII.GetBytes(values); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(string.Format("http://localhost:51436/api/employees")); request.Method = "PUT"; request.ContentType = "application/x-www-form-urlencoded"; using (var requestStream = request.GetRequestStream()) { requestStream.Write(bytes, 0, bytes.Length); } var response = (HttpWebResponse) request.GetResponse(); if (response.StatusCode == HttpStatusCode.OK) UpdateResponseLabel.Text = "Update completed"; else UpdateResponseLabel.Text = "Error in update"; }

如何使用WebRequest使用PUT方法。

  //JsonResultModel class public class JsonResultModel { public string ErrorMessage { get; set; } public bool IsSuccess { get; set; } public string Results { get; set; } } // HTTP_PUT Function public static JsonResultModel HTTP_PUT(string Url, string Data) { JsonResultModel model = new JsonResultModel(); string Out = String.Empty; string Error = String.Empty; System.Net.WebRequest req = System.Net.WebRequest.Create(Url); try { req.Method = "PUT"; req.Timeout = 100000; req.ContentType = "application/json"; byte[] sentData = Encoding.UTF8.GetBytes(Data); req.ContentLength = sentData.Length; using (System.IO.Stream sendStream = req.GetRequestStream()) { sendStream.Write(sentData, 0, sentData.Length); sendStream.Close(); } System.Net.WebResponse res = req.GetResponse(); System.IO.Stream ReceiveStream = res.GetResponseStream(); using (System.IO.StreamReader sr = new System.IO.StreamReader(ReceiveStream, Encoding.UTF8)) { Char[] read = new Char[256]; int count = sr.Read(read, 0, 256); while (count > 0) { String str = new String(read, 0, count); Out += str; count = sr.Read(read, 0, 256); } } } catch (ArgumentException ex) { Error = string.Format("HTTP_ERROR :: The second HttpWebRequest object has raised an Argument Exception as 'Connection' Property is set to 'Close' :: {0}", ex.Message); } catch (WebException ex) { Error = string.Format("HTTP_ERROR :: WebException raised! :: {0}", ex.Message); } catch (Exception ex) { Error = string.Format("HTTP_ERROR :: Exception raised! :: {0}", ex.Message); } model.Results = Out; model.ErrorMessage = Error; if (!string.IsNullOrWhiteSpace(Out)) { model.IsSuccess = true; } return model; }
