Page redirection (on Flickr) issue for WP7 WebBrowser
I am having some difficulties with the OAuth authentication process with Flickr in the WP7 Mango WebBrowser control. After for example "Google" sign in the browser gets redirected to the following page:
<html xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body dir="" onload="document.forms['f'].submit();">

</form>
</body>
</html>
When the browser has loaded the page i just see the very small button with the text "Continue to open.login.yahoo.com" which in my opinion is not that user friendly. Now you guys might think i didnt test with the IsScriptEnabled="True". With the IsScriptEnabled="True" it just hides the button and shosw a blank page.
I have also tried using the InvokeScript method inorder to run document.forms['f'].submit(), but i just recieve a COM-exception in the application.
Please help! Any tips or suggestions?
I have been pulling my hair with this problem but it seems that there has been made some changes in the WebBrowser control.
I just activate IsScriptEnabled="True" and it seems to trigger the form post. However before that i tried some other methods that seemed to work, one being:
loginBrowser.InvokeScript("eval", "document.forms[0].submit()");
However i came across another problem with one of the last redirects. A GET to the following, i guess it´s where we get the signature and link that we need inorder to authorize the app for our Flickr account (the link below was shortened and is non-functional).
GET /signin/yahoo/?redir=%2Fservices%2Fauth%2F%3Fmobile%3D6%26api_key%3D40d26ecdfghDhr4a1f62219c68d989df%26perms%3Dwrite%26api_sig%3Dcda4de52d6eca8e6db565cf8cd52e1f4&.data=Lnlp......
The solution was the following:
private void loginBrowser_Navigating(object sender, NavigatingEventArgs e)
{
if (e.Uri.ToString().Contains("http://www.flickr.com/signin/yahoo/?redir=/services/auth/?mobile=1") && _ishit == false)
{
_ishit = true;
e.Cancel = true;
}
}
I hope this helps someone!
