I'm discovering about NHtmlUnit to build an application web. But when I try it with auto login to yahoo mail. But after I run code. I refresh the login page of Yahoo so nothing changed. Not logged.
Code:
NHtmlUnit.WebClient driver = new NHtmlUnit.WebClient();
driver.Options.JavaScriptEnabled = true;
driver.Options.ThrowExceptionOnScriptError = false;
driver.Options.ActiveXNative = true;
driver.Options.CssEnabled = true;
HtmlPage page = driver.GetHtmlPage("https://login.yahoo.com/config/login?");
HtmlForm form = page.GetFormByName("login_form");
HtmlTextInput user = (HtmlTextInput)form.GetInputByName("login");
HtmlPasswordInput pass = (HtmlPasswordInput)form.GetInputByName("passwd");
user.SetValueAttribute("my account");
pass.SetValueAttribute("my pass");
HtmlSubmitInput submitButton = (HtmlSubmitInput)page.GetElementByName(".save");
HtmlPage nextpage = (HtmlPage)submitButton.Click();
Please help me why. I write it on .NET MVC 4 C#. Thank you very much.
Only update below single line,due to which u may face class cast exception
HtmlButton submitButton = (HtmlButton)page.GetElementByName(".save");
The code is completely fine, and should works.
Probably the reason you think it is not, is that you check it by a wrong method!
One essential elements which makes a site (i.e. login.yahoo.com) see you as logged in user, is the cookies it provide to your browser/webdriver when you use login forms, so if you use the login procedure by an instance of NHtmlUnit.Webclient (i.e. driver) then you are only logged in inside the driver web client, not inside any other browser or client, even on the same machine.
I tried to add this as a comment, but I don't have enough reputations.

I tried WebAuthenticator and it doesn't work.
I also tried using the deprecated GoogleApiClient with this method and the value is always null.
var person = PlusClass.PeopleApi.GetCurrentPerson(mGoogleApiClient)
I even tried adding email and profile scopes to my Google Fit Auth, but I can't get the email, profile etc...
I just tried this method, and it doesn't work either.
mSignInClient = GoogleSignIn.GetClient(this, options);
At this point, I'm stuck. Does anyone know how to get the user and profile information for the logged in user on a .Net Maui Android app???
Thanks!
I finally got this working by creating my own LoginActivity.
https://developers.google.com/identity/sign-in/android/sign-in
I'm calling the Activity using this code. It's running in an OnButtonClicked override in the LoginPage.xaml.cs file.
#if ANDROID
var myIntent = new Android.Content.Intent(Platform.CurrentActivity, typeof(LoginActivity));
Platform.CurrentActivity.StartActivityForResult(myIntent, 0);
#endif
Finally, the OnCreate method in the LoginActivity calls SignOn() after this line of code executes.
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
Ok, first question ever so be gentle. I've been struggling with this for about a week now and i am finally ready to accept defeat and ask for help.
Here's what is happening. I have an IdentityServer4 IDP, an API and an MVC Core Client. I am also interacting with 2 external OAuth2 IDPs provided by the business client.
My problem scenario is this:
The user logs in through my IDP(or potentially one of the external ones)
Once the user is in the Mvc Client they hit the back button on their browser
Which takes them back to the login page(whichever one they used)
They reenter the credentials(login again)
When redirected back(either to the MVC in the case of my IDP, or my IDP in the case of one of the external IDPs) i get RemoteFailure event with the message:correlation failed error
The problem seems, to me, to be the fact that you are trying to login when you are already logged in(or something). I've managed to deal with the case of logging in at my IDP, since the back button step takes the user to my Login action on the Controller(I then check if a user is authenticated and send them back to the MVC without showing them any page) but with the other two IDPs the back button does not hit any code in my IDP. Here are the config options for one of the OAuth2 external IDPs:
.AddOAuth(AppSettings.ExternalProvidersSettings.LoginProviderName, ExternalProviders.LoginLabel, o =>
{
o.ClientId = "clientId";
o.ClientSecret = "clientSecret";
o.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
o.CallbackPath = PathString.FromUriComponent(AppSettings.ExternalProvidersSettings.LoginCallbackPath);
o.AuthorizationEndpoint = AppSettings.ExternalProvidersSettings.LoginAuthorizationEndpoint;
o.TokenEndpoint = AppSettings.ExternalProvidersSettings.LoginTokenEndpoint;
o.Scope.Add("openid");
o.Events = new OAuthEvents
{
OnCreatingTicket = async context =>
{
//stuff
},
OnRemoteFailure = async context =>
{
if (!HostingEnvironment.IsDevelopment())
{
context.Response.Redirect($"/home/error");
context.HandleResponse();
}
}
};
}
The other one is the same. Since the error is exactly the same regardless of the IDP used, i am guessing it is not something native to OIDC but to OAuth middleware and the code(config options) they share, so i am not going to show the OIDC config on the MVC client(unless you insist). Given how simple the repro steps are i thought i would find an answer and explanation to my problem pretty fast, but i was not able to. Maybe the fix is trivial and i am just blind. Regardless of the situation, i would apreciate help.
I could reproduce your issue.
When the user goes back to the login screen after successfully logging in,
it might well be that the query parameters in the URL of that page are no longer valid.
Don't think this is an issue specific to Identity Server.

Not sure how to prevent this from happening though.
I'm trying to post to a Facebook page AS the page using the Unity Facebook SDK running on iOS. As I understand, to do that, I need the pages access token with manage_pages and publish_pages. I know that I can get it from /me/accounts?fields=access_token, but how do I tell AccessToken.CurrentAccessToken to use my pages access token instead?
Right now i'm using the following:
var wwwForm = new WWWForm();
//wwwForm.AddField ("access_token", "A-T I NEED");
wwwForm.AddBinaryData("image", screenshot, "InteractiveConsole.png");
wwwForm.AddField("message", "herp derp. I did a thing! Did I do this right?");
FB.API("/PAGE-ID/photos", HttpMethod.POST, HandleResult, wwwForm);
I tried putting the access token manually, but that didn't work (so I commented it out).
With this as it is I'm getting an error, telling me that I need publish_actions, wich is not correct since I'm not trying to post as the user. If I also get publish_actions the Post goes online, but is posted to the page as the user speaking. (User is also Admin)
Any Ideas ? Thanks!
So, I filed a bug report to facebook and as it turns out: "… at this time this functionality is not supported." Wich simply means there is now way to use the Page Access Token you acquired via the FB.API within the FB.API. And they are not going to tell you abot it in the documentation.
As a workaround I simply use a UnityWebRequest like this:
IEnumerator UploadToPage(byte[] screenshot) {
var wwwForm = new WWWForm();
wwwForm.AddField("message", "herp derp. I did a thing! Did I do this right?");
wwwForm.AddBinaryData("image", screenshot, "Test.png");
string url = "https" + "://graph.facebook.com/"+ PageID + "/photos";
url += "?access_token=" + PageAccessToken;
using (UnityWebRequest www = UnityWebRequest.Post(url, wwwForm))
{
yield return www.Send();
if (www.isError)
{
Debug.Log(www.error);
}
else
{
Debug.Log("Form upload complete!");
}
}
Debug.Log(url);
}
I have this in my config
callback = "http://xxx/oauth/facebook/callback"
successUri = "http://xxx/oauthCallBack/facebookSuccess"
failureUri = "http://xxx/oauthCallBack/facebookFailure"
and its working fine.
now the problem is, I have a sing in link in header which is shared amongst all pages, and when user click on it and authenticates using oauth, I want user to come back on same page from where he/she went for authentication.
How can this be done?
Any help much appreciated.
Thanks.
solved it myself.
Tried using referrer, but had some issues with it.
So
added hidden field with id=currentURL to form, and onLoad of body, populated this hidden field using javascript, eg:
function initParams() {
document.getElementById('currentURL').value = location.protocol + '//' + location.host + location.pathname;
}
and now I have currentURL in params in controller.
I can't seem to make any progress with this one. My CI session settings are these:
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 0;
$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie'] = FALSE;
$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_match_useragent'] = FALSE;
$config['sess_time_to_update'] = 7200;
$config['cookie_prefix'] = "";
$config['cookie_domain'] = "";
$config['cookie_path'] = "/";
$config['cookie_secure'] = FALSE;
The session library is loaded on autoload. I've commented the sess_update function to prevent an AJAX bug that I've found about reading the CI forum.
The ci_sessions table in the database has collation utf8_general_ci (there was a bug that lost the session after every redirect() call and it was linked to the fact that the collation was latin1_swedish_ci by default).
It always breaks after a user of my admin section tries to add a long article and clicks the save button. The save action looks like this:
function save($id = 0){
if($this->my_model->save_article($id)){
$this->session->set_flashdata('message', 'success!');
redirect('admin/article_listing');
}else{
$this->session->set_flashdata('message', 'errors encountered');
redirect('admin/article_add');
}
}
If you spend more than 20minutes and click save, the article will be added but on redirect the user will be logged out.
I've also enabled logging and sometimes when the error occurs i get the message The session cookie data did not match what was expected. This could be a possible hacking attempt. but only half of the time. The other half I get nothing: a message that I've placed at the end of the Session constructor is displayed and nothing else. In all the cases if I look at the cookie stored in my browser, after the error the cookie's first part doesn't match the hash.
Also, although I know Codeigniter doesn't use native sessions, I've set session.gc_maxlifetime to 86400.
Another thing to mention is that I'm unable to reproduce the error on my computer but on all the other computers I've tested this bug appears by the same pattern as mentioned above.
If you have any ideas on what to do next, I'd greatly appreciate them. Changing to a new version or using a native session class (the old one was for CI 1.7, will it still work?) are also options I'm willing to consider.
Edit : I've run a diff between the Session class in CI 2.0.3 and the latest CI Session class and they're the same.
Here's how I solved it: the standards say that a browser shouldn't allow redirects after a POST request. CI's redirect() method is sending a 302 redirect by default. The logical way would be to send a 307 redirect, which solved my problem but has the caveat of showing a confirm dialog about the redirect. Other options are a 301 (meaning moved permanently) redirect or, the solution I've chosen, a javascript redirect.
