Hey all,I have been working on a CMIS access layer in C#, and I have run into an issue that I cannot figure out. I am trying to set the content stream of a checked out document before checking it in.When I create a document from a file on my local machine, everything works fine. The document is created and returned, and I can retrieve the content of the document. The problem occurs when I am updating the content stream of a checked in document. When I run the code below, the content stream is updated, but as far as I can tell the base64 encoded content is not decoded. all files that I update with this code get turned into plain text files containing base64 strings, but they keep their original file extensions.I have examined the specification (0.5), and the way I interpret that version of setContentStream is to send the raw bits over as the PUT content, but if I do this (code not shown because it's simple) i get a 500 internal server error.Any help would be very appreciated.Here is my save to server code:
/// <summary>
/// Commits the changes to the document's data back to the server.
/// </summary>
public void Commit()
{
if(_contentChanged)
{
XDeclaration dec = new XDeclaration("1.0", "utf-8", "no");
XNamespace atom = "http://www.w3.org/2005/Atom";
XElement ele =
new XElement(atom + "entry",
new XElement(atom + "title", Title),
new XElement(atom + "content", Convert.ToBase64String(_data),
new XAttribute("type", MimeType),
new XAttribute("encoding", "base64")
)
);
byte[] data = System.Text.Encoding.UTF8.GetBytes(dec.ToString() + ele.ToString());
_repo.Server.PutRequest(_editMedia, data, "application/atom+xml;type=entry", new WebHeaderCollection());
}
}
and the PutRequest method:
/// <summary>
/// Executes an HTTP POST against a URI.
/// </summary>
/// <param name="uri">The URI to send the POST to.</param>
/// <param name="data">The data to include in the POST</param>
/// <param name="contentType">The MIME content type of the post.</param>
/// <param name="headers">The PUT headers for this request.</param>
/// <returns>The response stream.</returns>
internal Stream PutRequest(Uri uri, byte[] data, string contentType, WebHeaderCollection headers)
{
try
{
WebRequest request = WebRequest.Create(uri);
request.Headers = headers;
request.Method = "PUT";
request.Credentials = _credentials;
request.ContentType = contentType;
using(Stream str = request.GetRequestStream())
{
str.Write(data, 0, data.Length);
}
WebResponse response = request.GetResponse();
return response.GetResponseStream();
}
catch(WebException e)
{
throw new CmisException(uri, "There was a problem submitting the PUT request.", e);
}
}
For those not familiar with C#, what this does is create an ATOM entry for the document, enclosing the content in a base64 string, and then encoding the whole thing in Utf-8 for transfer.
