I need to HTTP post XML data to a URL that has Textarea with the name of XMLdata. My XMl data is ready and is inside of XDocument Sendingxml = xml; but the post code that I have tried is not working. Mostly because I don't know how to put the XML data in postData Variable as it only accept string. This is my code:
XDocument Sendingxml = xml;
// string Sendingxml = "<?xml version=1.0 encoding=UTF-8> <PluginData> <Credential UserName=avosfieldagent01 AuthenticationToken=61cc3957744742dca238c4dd7cbca702 /><Session><PropertyAddress>5 Crosskey</PropertyAddress><PropertyAddress2/><PropertyCity>California</PropertyCity><PropertyState>CA</PropertyState><PropertyZip>92620</PropertyZip><PropertyType>Condo</PropertyType><SourceReferenceId>45643</SourceReferenceId><SessionId>2013070100158346</SessionId><SessionCompleteReturnURL/><CustomerId/><BluebookOrderCheckSum>681a598cf23f412095f6092c281823e6</BluebookOrderCheckSum><BluebookOrderId>11160</BluebookOrderId> </Session></PluginData>";
// Create a request using a URL that can receive a post.
WebRequest request =
WebRequest.Create("https://test.bluebookcva.net/order/testdirectplugin/3");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "XMLData=" + Sendingxml; //My problem is here as I need postData as XDocument.
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();

In General:
An example of an easy way to post XML data and get the response (as a string) would be the following function:
public string postXMLData(string destinationUrl, string requestXml)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
byte[] bytes;
bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
request.ContentType = "text/xml; encoding='utf-8'";
request.ContentLength = bytes.Length;
request.Method = "POST";
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
HttpWebResponse response;
response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
string responseStr = new StreamReader(responseStream).ReadToEnd();
return responseStr;
}
return null;
}
In your specific situation:
Instead of:
request.ContentType = "application/x-www-form-urlencoded";
use:
request.ContentType = "text/xml; encoding='utf-8'";
Also, remove:
string postData = "XMLData=" + Sendingxml;
And replace:
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
with:
byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());
AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8 in the content type. It failed with a generic "Server Error" and it took hours to figure out what it didn't like:
request.ContentType = "text/xml; encoding=utf-8";
