{

private string WEBEX_SITE = "https://mywebex.webex.com/mywebexonline";

private string WEBEX_USER = "myuser", WEBEX_PASS = "pass123";

private string CURRENT_URL = "";

private CookieContainer cookieContainer = new CookieContainer();

protected void Page_Load(object sender, EventArgs e)

{

try

{

CURRENT_URL = HttpContext.Current.Request.Url.AbsoluteUri;

if (CURRENT_URL.IndexOf("?") > 0)

{

CURRENT_URL = CURRENT_URL.Substring(0, CURRENT_URL.IndexOf("?"));

}

doListMeetingAPI();

}

catch (Exception ex)

{

Response.Write("<br/>Err : " + ex.Message);

Response.Write("<br/>StackTrace : " + ex.StackTrace);

}

private void doListMeetingAPI()

{

try

result = callLoginAPI(WEBEX_USER, WEBEX_PASS).Trim();

csrfToken = parseCSRFToken(result);

if (csrfToken == null || csrfToken.Equals(""))

csrfToken = "";

}

///List Meeting

result = "";

result = callListMeetingAPI(WEBEX_SITE, csrfToken);

Response.Write("<br/>callListMeetingAPI : Data : " + result.Trim());

result = executePostCommand(listMeetingAPI,_params).ToString();

return result;

}

catch (Exception ex)

throw;

}

private string executePostCommand(string siteUrl, string _params)

{

try

{

string result = "";

HttpRequestCachePolicy policy = new HttpRequestCachePolicy(HttpRequestCacheLevel.Default);

HttpWebRequest.DefaultCachePolicy = policy;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(siteUrl);

request.CookieContainer = cookieContainer;

request.ContentLength = byteArray.Length;

Stream dataStream = request.GetRequestStream();

dataStream.Write(byteArray, 0, byteArray.Length);

dataStream.Close();

// Get the response.

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

int startIndex = responseAsString.ToString().IndexOf(findKey);

string responseSplitKey = responseAsString.Substring(startIndex);

int endIndex = responseSplitKey.IndexOf("\";");

string responseSplitVal = responseSplitKey.Substring(0, endIndex);

if (!responseSplitVal.Equals(""))

{

csrfToken = responseSplitVal;

}

return csrfToken;

}

================== Result =====================

Thank you so much

We urge all new development to use the XML API over the URL API, we have code examples for exactly what your trying to do with the XML API avilable here:

https://developer.cisco.com/site/webex-developer/develop-test/xml-api/sample-code/

Thank you so much for advise, Ryan Hunt.

Is possible if i give the URL API example code from you?.Because our site use the URL API.I was assigned to fix and develop.

We do not provide code examples for the URL API..

It appears as if you are not appending the CSRF token to your request.
