OK, so I'm working on an ASP.NET webapp with AJAX and the Windows Live ID SDK. I've successfully gotten it to authenticate via Live, however...
The Windows Live ID spec indicates that I have to look for request headers "login", "logout", and "clearcookie". The recommended code samples include a Response.Redirect, which doesn't seem to work when your page has extensive use of UpdatePanels:
loginCookie = new HttpCookie(strLoginCookie);
loginCookie.Expires = DateTime.Now.AddYears(-10);
Response.Cookies.Add(loginCookie);
Response.Redirect("default.aspx");
Response.End();
Further, the clearcookie Action requires I write directly to the Response:
public WindowsLiveLogin wll = new WindowsLiveLogin(key1, key2);
loginCookie = new HttpCookie(strLoginCookie);
loginCookie.Expires = DateTime.Now.AddYears(-10);
Response.Cookies.Add(loginCookie);
string type;
byte[] content;
wll.GetClearCookieResponse(out type, out content);
Response.ContentType = type;
Response.OutputStream.Write(content, 0, content.Length);
As a result, the response doesn't recognize it and the Windows Live logout feature times out, whether doing it via my logout button (logout Action) or the Windows Live site's logout feature (clearcookie Action). How can this be accomplished with static UpdatePanels and other AJAX controls in the markup?
I used this in a former AJAX project. I settled for not having logout functionality, which of course can be bypassed by clearing one's cookies. Please tell me a more elegant way!

I am trying to make some further adjustments to an address text field. But the problem is that its made with airtable. I want to get the input of that address and use it to get some data from zillow API for the user. How can I do this? I have viewed the source HTML and I only see the airtable script.
This probably went unanswered for being too vague. I'll try to leave some pointers if anyone stumbles upon this in the future.
Are you the host of the WP page? do you have access to the Airtable base in question? Is the "frontend" viewable? Airtable's API is pretty well-documented, simple as it may be. Whatever you need, if it's from a shared view, it can be fetched with a curl request.
Other than that,if the base is public, or shared publicly, and particularly if you need this data at a steady rate or in larger quantities, you'd be better off requesting access and collecting the information with a script from the Scripting app. Since ES6, this is as trivial as doing something like
let query = await base.getTable
(cursor.activeTableId)
.selectRecordsAsync()
let payload, selectAll = query.records.map(rec => rec.name),
selectAll ?
payload = { records: JSON.stringify(selectAll) }
: console.error('something went wrong')
remoteFetchAsync(('your scraping endpoint', payload)=>
//rock'n'roll past this point
})
UPDATE: Google has recently updated their error message with an additional error code possibility: "timeout-or-duplicate".
This new error code seems to cover 99% of our previously mentioned mysterious
cases.
We are still left wondering why we get that many validation requests that are either timeouts or duplicates. Determinining this with certainty is likely to be impossible, but now I am just hoping that someone else has experienced something like it.
Disclaimer: I cross posted this to Google Groups, so apologies for spamming the ether for the ones of you who frequent both sites.
I am currently working on a page as part of a ASP.Net MVC application with a form that uses reCAPTCHA validation. The page currently has many daily users.
In my server side validation** of a reCAPTCHA response, for a while now, I have seen the case of the reCAPTCHA response having its success property set to false, but with an accompanying empty error code array.
Most of the requests pass validation, but some keep exhibiting this pattern.
So after doing some research online, I explored the two possible scenarios I could think of:
The validation has timed out and is no longer valid.
The user has already been validated using the response value, so they are rejected the second time.
After collecting data for a while, I have found that all cases of "Success: false, error codes: []" have either had the validation be rather old (ranging from 5 minutes to 10 days(!)), or it has been a case of a re-used response value, or sometimes a combination of the two.
Even after implementing client side prevention of double-clicking my submit-form button, a lot of double submits still seem to get through to the server side Google reCAPTCHA validation logic.
My data tells me that 1.6% (28) of all requests (1760) have failed with at least one of the above scenarios being true ("timeout" or "double submission").
Meanwhile, not a single request of the 1760 has failed where the error code array was not empty.
I just have a hard time imagining a practical use case where a ChallengeTimeStamp gets issued, and then after 10 days validation is attempted, server side.
My question is:
What could be the reason for a non-negligible percentage of all Google reCAPTCHA server side validation attempts to be either very old or a case of double submission?
**By "server side validation" I mean logic that looks like this:
public bool IsVerifiedUser(string captchaResponse, string endUserIp)
{
string apiUrl = ConfigurationManager.AppSettings["Google_Captcha_API"];
string secret = ConfigurationManager.AppSettings["Google_Captcha_SecretKey"];
using (var client = new HttpClient())
{
var parameters = new Dictionary<string, string>
{
{ "secret", secret },
{ "response", captchaResponse },
{ "remoteip", endUserIp },
};
var content = new FormUrlEncodedContent(parameters);
var response = client.PostAsync(apiUrl, content).Result;
var responseContent = response.Content.ReadAsStringAsync().Result;
GoogleCaptchaResponse googleCaptchaResponse = JsonConvert.DeserializeObject<GoogleCaptchaResponse>(responseContent);
if (googleCaptchaResponse.Success)
{
_dal.LogGoogleRecaptchaResponse(endUserIp, captchaResponse);
return true;
}
else
{
//Actual code ommitted
//Try to determine the cause of failure
//Look at googleCaptchaResponse.ErrorCodes array (this has been empty in all of the 28 cases of "success: false")
//Measure time between googleCaptchaResponse.ChallengeTimeStamp (which is UTC) and DateTime.UtcNow
//Check reCAPTCHAresponse against local database of previously used reCAPTCHAresponses to detect cases of double submission
return false;
}
}
}
Thank you in advance to anyone who has a clue and can perhaps shed some light on the subject.
You will get timeout-or-duplicate problem if your captcha is validated twice.
Save logs in a file in append mode and check if you are validating a Captcha twice.
Here is an example
$verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response'])
file_put_contents( "logfile", $verifyResponse, FILE_APPEND );
Now read the content of logfile created above and check if captcha is verified twice
This is an interesting question, but it's going to be impossible to answer with any sort of certainly. I can give an educated guess about what's occurring.
As far as the old submissions go, that could simply be users leaving the page open in the browser and coming back later to finally submit. You can handle this scenario in a few different ways:
Set a meta refresh for the page, such that it will update itself after a defined period of time, and hopefully either get a new ReCAPTCHA validation code or at least prompt the user to verify the CAPTCHA again. However, this is less than ideal as it increases requests to your server and will blow out any work the user has done on the form. It's also very brute-force: it will simply refresh after a certain amount of time, regardless of whether the user is currently actively using the page or not.
Use a JavaScript timer to notify the user about the page timing out and then refresh. This is like #1, but with much more finesse. You can pop a warning dialog telling the user that they've left the page sitting too long and it will soon need to be refreshed, giving them time to finish up if they're actively using it. You can also check for user activity via events like onmousemove. If the user's not moving the mouse, it's very likely they aren't on the page.
Handle it server-side, by catching this scenario. I actually prefer this method the most as it's the most fluid, and honestly the easiest to achieve. When you get back success: false with no error codes, simply send the user back to the page, as if they had made a validation error in the form. Provide a message telling them that their CAPTCHA validation expired and they need to verify again. Then, all they have to do is verify and resubmit.
The double-submit issue is a perennial one that plagues all web developers. User behavior studies have shown that the vast majority occur because users have been trained to double-click icons, and as a result, think they need to double-click submit buttons as well. Some of it is impatience if something doesn't happen immediately on click. Regardless, the best thing you can do is implement JavaScript that disables the button on click, preventing a second click.
Current Project:
ASP.NET 4.5.2
MVC 5
PayPal API
I am using this example to build myself a PayPal transaction (and yes, my code is virtually identical), as I do not know of any other method that will return the three values in the title.
My main problem is that, the example I am utilizing is much more concise and compact than the one I used for a much older Web Forms application, and as such, I am unsure as to where or even how to grab the three values I need.
My initial thought was to do so right after the ACK, and indeed I was able to obtain the CorrelationId as well as the TimeStamp, but because this was prior to the user being carted off to PayPal’s site (sandbox in this case -- see the return new PayPalRedirect contained within the if), the TransactionId was blank. And in this example, PayPal explicitly redirects the user to a Success page without returning to the Action that sent the user to PayPal in the first place, and I am not seeing any GET values in the URL at all aside from the Token and the PayerId, much less ones that could provide me with the TransactionId.
Suggestions?
I have also looked at the following examples:
For ASP.NET Core, was unsure how to adapt to my current project particularly due to appsettings.json, but it looked quite well done. I really liked how the values were rolled up in lists.
For MVC 4, but I couldn’t find where ACK was being used to determine success or successwithwarning so I couldn’t hook into that.
I have also found the PayPal content to be like trying to drink from a fire hose at full blast -- not only was the content was hopelessly outdated (Web Forms code, FTW!) but there was also so many different examples it would have taken me days to determine which one was most appropriate to use.
Any assistance would be greatly appreciated.
Edit: my initial attempt at modifying the linked code has this portion:
values = Submit(values);
var ack = values["ACK"].ToLower();
if(ack == "success" || ack == "successwithwarning") {
using(_db = new ApplicationDbContext()) {
var updateOrder = await _db.Orders.FirstOrDefaultAsync(x => x.OrderId == order.OrderId);
if(updateOrder != null) {
updateOrder.OrderProcessed = false;
updateOrder.PayPalCorrelationId = values["CORRELATIONID"];
updateOrder.PayPalTransactionId = values["TRANSACTIONID"];
updateOrder.PayPalTimeStamp = values["TIMESTAMP"];
updateOrder.IPAddress = HttpContext.Current.Request.UserHostAddress;
_db.Entry(updateOrder).State = EntityState.Modified;
await _db.SaveChangesAsync();
}
}
return new PayPalRedirect {
Token = values["TOKEN"],
Url = $"https://{PayPalSettings.CgiDomain}/cgi-bin/webscr?cmd=_express-checkout&token={values["TOKEN"]}"
};
}
Everything within and including the using() is my added content. As I mentioned, the CorrelationId and the TimeStamp come through just fine, but I have yet to successfully obtain the TransactionId.
Edit 2:
More problems -- the transactions that are “successful” through the sandbox site (the ReturnUrl is getting called) aren’t reflecting properly on my Facilitator and Buyer accounts, even when I do payments straight from the buyer’s PayPal account (not using the Credit Card). I know I am supposed to see transactions in the Buyer’s account, either through the overall Dev account (Accounts -> Profile -> balance or Accounts -> Notifications) or through the Buyer’s account in the sandbox front end. And yet -- multiple transactions returning me to the ReturnUrl path, and yet no transactions in either.
Edit 3:
Okay, this is really, really weird. I have gone over all settings with a fine-toothed comb, and intentionally introduced errors to see where things should crap out. It turns out that the entire process goes swimmingly - except nothing shows up in my notifications and no amounts get moved between my different accounts (Facilitator and Buyer). It’s like all my transactions are going into /dev/null, yet the process is successful.
Edit 4: A hint!
In the sandbox, where Buyer accepts the transaction, there is a small note, “You will be able to review the transaction before completing it” or something like that -- suggesting that an additional page is not coming up and that the user is being uncerimoniously dumped back to the success page. Why the success page? No clue. But it’s happening.
It sounds like you are only doing the first part of the process.
Express Checkout consists of 3 API calls:
SetExpressCheckout
GetExpressCheckoutDetails
DoExpressCheckoutPayment
SEC generates a token, and then you redirect to PayPal where the user signs in and reviews the transactions before agreeing to pay.
They are then sent to the ReturnURL included in your SEC request, and this is where you'll call GECD in order to obtain all the buyer details that are now available since they signed in.
Using that data you can complete the final DECP request, which is what finalizes the procedure. No money is actually processed until this final call is completed successfully.
I am doing my best to try and get a .net webforms twilio app up and running but I am stuck at one part which I haven't found an answer too throughout all the blog posts and tutorials I have read. I have found numerous stack overflow questions but no real answer yet.
Basically: I have an .aspx page that executes: var call = client.InitiateOutboundCall(options);,
which has the url set as an ashx page that has:
twiml.BeginGather(new {
action = "http://sydheller.com/default.aspx",
numDigits = "1"});
twiml.Say("Please enter your PIN");
twiml.Hangup();
and then on that default.aspx in the Page_Load I have:
if (Request.Form["Digits"] != null)
{
string digits = Request.Form["Digits"];
digitsLabel.Text = digits;
}
When I click the button to make the call, I get the call and complete it and it hangs up but nothing happens on my page. I assume I need to use AJAX somehow but I am not sure how to write an ajax request to get information from something that the twilio api/ashx page is posting back.
Does that make sense?
This is driving me crazy and I have a feeling that it is something not particularly complicated that I just don't know and cant figure out.
I would really appreciate any help anyone could throw my way!
Thank you so much in advance,
Syd

I'm working on an old project that needs some extra functionality. It uses symfony 1.4. I'm new to symfony.
There are 4 actions now:
executeAdmin, executeDashboard, executeHome, executeView that work well. They are in a file called action.class.php.
The routing looks like this (in routing.yml):
editor:
url: /editor/:action/*
param: { module: bookeditor }
It was my assumption that creating a new executeTest in the same action.class.php would work out of the box.
private function executeUpload ( $request ) {
$this->response->setContent("<h1>Ok!</h1>");
return sfView::NONE;
}
When going to mysite/editor/upload I get the 404 page.
If I replace the code of executeAdmin for example:
private function executAdmin ( $request ) {
$this->response->setContent("<h1>Ok!</h1>");
return sfView::NONE;
}
When going to mysite/editor/admin I get the "Ok" on a blank page.
Why does this happen? How can I fix this?
(I cleared the symfony cache and restarted apache after each change.)
execute* function inside the controller must be public.
Also you have a typo here: executAdmin. It should be executeAdmin.
