I'm trying to create/modify dotclear blogs.
For most of the options, i use XmlRpc API (DotClear.MetaWeblog). But didn't find any way to handle categories.
So I start to look at the Http packet and try to do "the same as the browser".
Here si the method I use to "Http POST"
protected HttpStatusCode HttpPost(Uri url_, string data_, bool allowAutoRedirect_)
{
HttpWebRequest Request;
HttpWebResponse Response = null;
Stream ResponseStream = null;
Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(url_);
Request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729)";
Request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
Request.AllowAutoRedirect = allowAutoRedirect_;
// Add the network credentials to the request.
Request.Credentials = new NetworkCredential(Username, Password);
string authInfo = Username + ":" + Password;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
Request.Headers["Authorization"] = "Basic " + authInfo;
Request.Method = "POST";
Request.CookieContainer = Cookies;
if(ConnectionCookie!=null)
Request.CookieContainer.Add(url_, ConnectionCookie);
if (dcAdminCookie != null)
Request.CookieContainer.Add(url_, dcAdminCookie);
Request.PreAuthenticate = true;
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = data_;
byte[] data = encoding.GetBytes(postData); //Encoding.UTF8.GetBytes(data_); //encoding.GetBytes(postData);
Request.ContentLength = data.Length;
Request.ContentType = "application/x-www-form-urlencoded";
Stream newStream = Request.GetRequestStream();
// Send the data.
newStream.Write(data, 0, data.Length);
newStream.Close();
try
{
// get the response from the server.
Response = (HttpWebResponse)Request.GetResponse();
if (!allowAutoRedirect_)
{
foreach (Cookie c in Response.Cookies)
{
if (c.Name == "dcxd")
ConnectionCookie = c;
if (c.Name == "dc_admin")
dcAdminCookie = c;
}
Cookies.Add(Response.Cookies);
}
// Get the response stream.
ResponseStream = Response.GetResponseStream();
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader(ResponseStream, Encoding.UTF8);
string result = readStream.ReadToEnd();
if (Request.RequestUri == Response.ResponseUri)
{
_log.InfoFormat("{0} ==> {1}({2})", Request.RequestUri, Response.StatusCode, Response.StatusDescription);
}
else
{
_log.WarnFormat("RequestUri:{0}\r\nResponseUri:{1}\r\nstatus code:{2} Status descr:{3}", Request.RequestUri, Response.ResponseUri, Response.StatusCode, Response.StatusDescription);
}
}
catch (WebException wex)
{
Response = wex.Response as HttpWebResponse;
if (Response != null)
{
_log.ErrorFormat("{0} ==> {1}({2})", Request.RequestUri, Response.StatusCode, Response.StatusDescription);
}
Request.Abort();
}
finally
{
if (Response != null)
{
// Releases the resources of the response.
Response.Close();
}
}
if(Response !=null)
return Response.StatusCode;
return HttpStatusCode.Ambiguous;
}
So the first thing to do is to Authenticate as admin.
Here is the code:
protected bool HttpAuthenticate()
{
Uri u = new Uri(this.Url);
Uri url = new Uri(string.Format("{0}/admin/auth.php", u.GetLeftPart(UriPartial.Authority)));
string data = string.Format("user_id={0}&user_pwd={1}&user_remember=1", Username, Password);
var ret = HttpPost(url,data,false);
return (ret == HttpStatusCode.OK || ret==HttpStatusCode.Found);
}
3.Now that I'm authenticate, i need to get a xd_chek info (that i can find on the page so basically it's a GET on /admin/category.php + Regex("dotclear[.]nonce = '(.*)'"))
4.so I'm authenticate and have the xd_check info. The last thing to do seems to post the next category. But of course it does not work at all...
here is the code:
string postData = string.Format("cat_title={0}&new_cat_parent={1}&xd_check={2}", category_, 0, xdCheck);
HttpPost(url, postData, true);
If anyone can help me and explain were is it wrong ?
thanks in advance.
