cmis deleteTree in web script

[silenr0c]

Hi Folks,

I try to delete folder using cmis.deleteTree in webscript, following is js code, but I get error below.
Not sure because deleteTree is non existant function or there are some wrong parameter in it.
I'm not so sure UnfileObject.DELETE is valid.

p.s. I notice there are some api, but it stated as deprecated in lifecycle so I didn't bother to try it.

Hi Kaynezhang,

Thanks for your reply, I manage to try out with asp.net
Following is someone else's code I found in the internet, I just make little changes.

//Delete Folder
string endpointAddress = @"http://localhost:8080/alfresco/service/cmis/p/User Homes/Folder to be deleted/tree";
GetWebScriptResponse("DELETE", string.Empty, endpointAddress, "admin", "admin");

public static string GetWebScriptResponse(string method, string postData, string endpointAddress, string username, string password)
{
    string _auth = string.Format("{0}:{1}", username, password);
    string _enc = Convert.ToBase64String(Encoding.ASCII.GetBytes(_auth));
    string _cred = string.Format("{0} {1}", "Basic", _enc);

    /* WebProxy proxyObject = new WebProxy("http://youralfrescowebsite:8080/',true);*/
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(endpointAddress);
    /* req.Proxy = proxyObject;*/

    req.Timeout = 20 * 60 * 1000;
    req.ReadWriteTimeout = 20 * 60 * 1000;
    req.Method = method;
    if (postData.Length > 0)
    {
        req.ContentType = "application/json;charset=UTF-8";
        req.ContentLength = postData.Length;
    }
    req.AuthenticationLevel = System.Net.Security.AuthenticationLevel.MutualAuthRequired;
    NetworkCredential nc = new NetworkCredential(username, password);
    req.Credentials = nc;
    req.Headers[HttpRequestHeader.Authorization] = _cred;
    string response = null;

    Stream dataStream = null;
    try
    {
        if (POST.Equals(method) || PUT.Equals(method))
        {
            using (StreamWriter sw = new StreamWriter(req.GetRequestStream(),
            System.Text.Encoding.ASCII))
            {
                sw.Write(postData);
                sw.Flush();
            }
        }
        using (StreamReader sr = new StreamReader(req.GetResponse().GetResponseStream()))
        {
            response = sr.ReadToEnd();
        }
        req.GetResponse().Close();

    }
    catch (Exception e)
    {                
        response = "Exception: " + e.Message + "; " + e.ToString();
    }

    return response;
}
