Can you modify your code to write the detailed reason in the log? Such as: user == null, or user.EmailConfirmationCode.IsNullOrEmpty()

You can also write the UserId and ConfirmationCode to the log at the same time to help you find the cause of the problem.

Hi,

public async Task ActivateEmail(ActivateEmailInput input)
        {
            var user = await UserManager.GetUserByIdAsync(input.UserId);
            Logger.InfoFormat("user is null: {0}", user == null);
            if (user != null)
            {
                Logger.InfoFormat("user confirmaion code: {0}", user.EmailConfirmationCode);
                Logger.InfoFormat("input confirmaion code: {0}", input.ConfirmationCode);
                Logger.InfoFormat("confirmaion code match: {0}", user.EmailConfirmationCode == input.ConfirmationCode);
            }
            if (user == null || user.EmailConfirmationCode.IsNullOrEmpty() || user.EmailConfirmationCode != input.ConfirmationCode)
            {
                throw new UserFriendlyException(L("InvalidEmailConfirmationCode"), L("InvalidEmailConfirmationCode_Detail"));
            }

            user.IsEmailConfirmed = true;
            user.EmailConfirmationCode = null;

            await UserManager.UpdateAsync(user);
        }

I added logging. The issue occures only sometimes. The issue comes frequently on chrome incognito mode.

INFO  2019-07-22 08:46:45,059 [28   ] Authorization.Accounts.AccountAppService - user is null: False
INFO  2019-07-22 08:46:45,059 [28   ] Authorization.Accounts.AccountAppService - user confirmaion code:

INFO  2019-07-22 08:46:45,059 [28   ] Authorization.Accounts.AccountAppService - confirmaion code match: False

Any idea why this happens?

It is possible that the ActivateEmail method was called multiple times (the link was clicked multiple times or requested multiple times). Can you look at the audit log?

I could not find any duplicate records for ActivateEmail method in audit logs. i have created a mobile application and when the user is created the email is send to their email address. When they click on the link from the mobile borwser sometime this issue happens.

I guess even if this problem occurs, the user will actually be activated, right?

firnas created 5 years ago

yes. Did you figure out what is causing the issue?

I still think that the ActivateEmail method has been called multiple times. There is no other reason other than this.

You can also get a link and then open it multiple times, and the same error should occur.

ok i will investigate further and let you know the results

I am using has based routing in the angular application.

[RouterModule.forRoot(routes,{useHash:true})]

so the email confirmation url contains a #. Is this causing the issue of multiple times the method to be called?

I am not quite sure, no one mentioned this in google search. Have you tried using the history api?

firnas created 5 years ago

what is the history API? I think this is due to the # in the url. I had to change the confirmation code generating code becuse it was not generating the correct encryption.

 private string EncryptQueryParameters(string link, string encrptedParameterName = "c")
        {
            if (!link.Contains("?"))
            {
                return link;
            }

            var basePath = link.Substring(0, link.IndexOf('?'));
            if (link.Contains("#/"))
            {
                link = link.Replace("#/", string.Empty);
            }

            var uri = new Uri(link);
            var query = uri.Query.TrimStart('?');

            return basePath + "?" + encrptedParameterName + "=" + HttpUtility.UrlEncode(SimpleStringCipher.Instance.Encrypt(query));
        }

I mean using PathLocationStrategy to see if the above problem still occurs.

I think this is due to the # in the url. I had to change the confirmation code generating code becuse it was not generating the correct encryption.

Does this solve your problem?

firnas created 5 years ago

i am clicking on the confirmation email url which has a # in it. That is where the problem happens. i will check PathLocationStrategy and see.

hi firnas I will modify the EncryptQueryParameters method. It currently does not consider the case where there is a # in the url. . I believe this should be the cause of the problem.

hi firnas.

Try replace the EncryptQueryParameters method with the following code.

private string EncryptQueryParameters(string link, string encrptedParameterName = "c")
{
	if (!link.Contains("?"))
	{
		return link;
	}

	var basePath = link.Substring(0, link.IndexOf('?'));
	var query = link.Substring(link.IndexOf('?')).TrimStart('?');

	return basePath + "?" + encrptedParameterName + "=" + HttpUtility.UrlEncode(SimpleStringCipher.Instance.Encrypt(query));
}

Hi maliming,

I replace the code and now it generates the correct email confirmation link even when the # is in the link. I will check if i still get the error when clicking on the link and update here.

The error when clicking on the email activation link is still coming. When clicked on the link the routing happens twice it seems. Is there a way how to stop this?

maliming created 5 years ago

I guess this may be related to your browser.

If you can't solve the problem that the link is accessed multiple times, you can modify the ActivateEmail method.

Skip detection logic if the user's mail has been activated.

public async Task ActivateEmail(ActivateEmailInput input)
{
	var user = await UserManager.GetUserByIdAsync(input.UserId);
	if(user != null && user.IsEmailConfirmed)
	{
		return;
	}
	
	if (user == null || user.EmailConfirmationCode.IsNullOrEmpty() || user.EmailConfirmationCode != input.ConfirmationCode)
	{
		throw new UserFriendlyException(L("InvalidEmailConfirmationCode"), L("InvalidEmailConfirmationCode_Detail"));
	}

	user.IsEmailConfirmed = true;
	user.EmailConfirmationCode = null;

	await UserManager.UpdateAsync(user);
}
