Problem to get the auth code

SimonFan

Hi All: I have a problem when I was trying to get the auth code. I am using WPF and tring to get the "auth-code-input" from the webpage that dropbox direct to. But the when I was using the following code it alway get null. For now, I set the redirct_uri to empty, does this matter?

 

 

mshtml.IHTMLDocument3 doc3 = WebBrowserAuth.Document as mshtml.IHTMLDocument3;
var myHtmlElement = doc3.getElementById("auth-code-input");
string strAuthCode = myHtmlElement.getAttribute("value");

 

Many thanks in advance!

I'm not sure I understand your question, but it sounds like you may be trying to query the authorization code out of the HTML of the page after the user authorizes your app on /oauth2/authorize.

You shouldn't try to retrieve the authorization code that way, as that page is subject to change. If you want to get the authorization code programmatically, you should instead supply a redirect URI and get it from the URL parameter itself. You can find more information on how this works here:
