Festlegen der Körperdaten einer WebRequest

Question

Ich erstelle eine Web-Anfrage in ASP.NET und ich muss eine Menge Daten in den Körper hinzufügen. Wie mache ich das?

var request = HttpWebRequest.Create(targetURL); 
request.Method = "PUT"; 
response = (HttpWebResponse)request.GetResponse(); 

Answer 1

Mit HttpWebRequest.GetRequestStream

Codebeispiel von http://msdn.microsoft.com/en-us/library/d4cek6cc.aspx

string postData = "firstone=" + inputData; 
ASCIIEncoding encoding = new ASCIIEncoding(); 
byte[] byte1 = encoding.GetBytes (postData); 

// Set the content type of the data being posted. 
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded"; 

// Set the content length of the string being posted. 
myHttpWebRequest.ContentLength = byte1.Length; 

Stream newStream = myHttpWebRequest.GetRequestStream(); 

newStream.Write (byte1, 0, byte1.Length); 

Von einem meiner eigenen Code:

var request = (HttpWebRequest)WebRequest.Create(uri); 
request.Credentials = this.credentials; 
request.Method = method; 
request.ContentType = "application/atom+xml;type=entry"; 
using (Stream requestStream = request.GetRequestStream()) 
using (var xmlWriter = XmlWriter.Create(requestStream, new XmlWriterSettings() { Indent = true, NewLineHandling = NewLineHandling.Entitize, })) 
{ 
    cmisAtomEntry.WriteXml(xmlWriter); 
} 

try 
{  
    return (HttpWebResponse)request.GetResponse(); 
} 
catch (WebException wex) 
{ 
    var httpResponse = wex.Response as HttpWebResponse; 
    if (httpResponse != null) 
    { 
     throw new ApplicationException(string.Format(
      "Remote server call {0} {1} resulted in a http error {2} {3}.", 
      method, 
      uri, 
      httpResponse.StatusCode, 
      httpResponse.StatusDescription), wex); 
    } 
    else 
    { 
     throw new ApplicationException(string.Format(
      "Remote server call {0} {1} resulted in an error.", 
      method, 
      uri), wex); 
    } 
} 
catch (Exception) 
{ 
    throw; 
} 

Answer 2

sollte diese helfen:

var request = (HttpWebRequest)WebRequest.Create("http://example.com/page.asp"); 

string stringData = ""; //place body here 
var data = Encoding.ASCII.GetBytes(stringData); // or UTF8 

request.Method = "PUT"; 
request.ContentType = ""; //place MIME type here 
request.ContentLength = data.Length; 

var newStream = request.GetRequestStream(); 
newStream.Write(data, 0, data.Length); 
newStream.Close();
