Class WebDAVClient
Object
dw.net.WebDAVClient
The WebDAVClient class supports the WebDAV methods GET, PUT, MKCOL, MOVE, COPY, PROPFIND,OPTIONS and DELETE.

Note: when this class is used with sensitive data, be careful in persisting sensitive information to disk. The client can be used as shown in the following example:

 var webdavClient : WebDAVClient = new WebDAVClient("http://mywebdav.server.com","myusername", "mypassword");
 var getString : String = webdavClient.get("myData.xml","UTF-8");
 var message : String;

 if (webdavClient.succeeded())
 {
      message = webDavClient.statusText;
 }
 else
 {
     // error handling
     message="An error occured with status code "+webdavClient.statusCode;
 }

 var data : XML = new XML(getString);
 

The WebDAV client supports the following authentication schemes:

  • Basic authentication
  • Digest authentication
The methods of this class do not generally throw exceptions if the underlying WebDAV operation do not succeed.The result of a WebDAV operation can be checked using the methods succeeded(), getStatusCode(), and getStatusText().

Important note: This WebDAV client cannot be used to access the Commerce Cloud Digital server via WebDAV protocol.
