Upload a file to SharePoint through the built-in web services

Question

What is the best way to upload a file to a Document Library on a SharePoint server through the built-in web services that version WSS 3.0 exposes?

Following

Answer 1

public static void UploadFile(byte[] fileData) {
  var copy = new Copy {
    Url = "http://servername/sitename/_vti_bin/copy.asmx", 
    UseDefaultCredentials = true
  };

  string destinationUrl = "http://servername/sitename/doclibrary/filename";
  string[] destinationUrls = {destinationUrl};

  var info1 = new FieldInformation
                {
                  DisplayName = "Title", 
                  InternalName = "Title", 
                  Type = FieldType.Text, 
                  Value = "New Title"
                };

  FieldInformation[] info = {info1};
  var copyResult = new CopyResult();
  CopyResult[] copyResults = {copyResult};

  copy.CopyIntoItems(
    destinationUrl, destinationUrls, info, fileData, out copyResults);
}

NOTE: Changing the 1st parameter of CopyIntoItems to the file name, Path.GetFileName(destinationUrl), makes the unlink message disappear.

I've had good luck using the DocLibHelper wrapper class described here: http://geek.hubkey.com/2007/10/upload-file-to-sharepoint-document.html

Not sure on exactly which web service to use, but if you are in a position where you can use the SharePoint .NET API Dlls, then using the SPList and SPLibrary.Items.Add is really easy.

Answer 4

Another option is to use plain ol' HTTP PUT:

WebClient webclient = new WebClient();
webclient.Credentials = new NetworkCredential(_userName, _password, _domain);
webclient.UploadFile(remoteFileURL, "PUT", FilePath);
webclient.Dispose();

Where remoteFileURL points to your SharePoint document library...

Example of using the WSS "Copy" Web service to upload a document to a library...

public static void UploadFile2007(string destinationUrl, byte[] fileData)
{
    // List of desination Urls, Just one in this example.
    string[] destinationUrls = { Uri.EscapeUriString(destinationUrl) };

    // Empty Field Information. This can be populated but not for this example.
    SharePoint2007CopyService.FieldInformation information = new 
        SharePoint2007CopyService.FieldInformation();
    SharePoint2007CopyService.FieldInformation[] info = { information };

    // To receive the result Xml.
    SharePoint2007CopyService.CopyResult[] result;

    // Create the Copy web service instance configured from the web.config file.
    SharePoint2007CopyService.CopySoapClient
    CopyService2007 = new CopySoapClient("CopySoap");
    CopyService2007.ClientCredentials.Windows.ClientCredential = 
        CredentialCache.DefaultNetworkCredentials;
    CopyService2007.ClientCredentials.Windows.AllowedImpersonationLevel = 
        System.Security.Principal.TokenImpersonationLevel.Delegation;

    CopyService2007.CopyIntoItems(destinationUrl, destinationUrls, info, fileData, out result);

    if (result[0].ErrorCode != SharePoint2007CopyService.CopyErrorCode.Success)
    {
        // ...
    }
}

From a colleage at work:

Lazy way: your Windows WebDAV filesystem interface. It is bad as a programmatic solution because it relies on the WindowsClient service running on your OS, and also only works on websites running on port 80. Map a drive to the document library and get with the file copying.

There is additionally a web service to upload files, painful but works all the time.

I believe you are able to upload files via the FrontPage API but I don’t know of anyone who actually uses it.
