I have a big problem with Internet Explorer 7 and 8.
SITUATION:
I have a FORM that build a Medical Prescription. When I hit the save button, the script saves the DomainObject on DB and set a boolean property (of panel where the form is added) called "saved" to true and a byte[] property called PDF with bytestream.
On RenderHead of Panel, I read this boolean and, if is true, I force the trigger of a hidden button with this code:
String js = "$('#" + printPDF.getMarkupId() + "').click();";
response.renderOnDomReadyJavaScript(js);
The button executes this code:
ResourceStreamRequestHandler handler = new ResourceStreamRequestHandler(new ByteArrayResourceStream(pdf, "application/pdf"));
handler.setFileName("foo.pdf");
RequestCycle.get().scheduleRequestHandlerAfterCurrent(handler);
This code work perfecly on FF and Chrome. The Browser download windows appears and the user can save the PDF on HD.
Unfortunally, Internet Explorer has that damn security behavior that is triggered when a site require something to download. That warning require a user validation. A yellow Bar appear and the user is force to hit "Download".

When I hit Download File, the form is submitted again with the exact state I had when I hit save the first time. So no previous INSERT on DB is already committed; The Session is resetted to the previous state etc...
The result is a double INSERT on DB of the Domain Ojbect.
Any clue to resolve this?
The problem is that you click download link programaticly instead to redirect browser to an URL or open an URL by JS window.open(url). Click a link looks like an unwanted operation that is sometimes restricted by browser.

I'm experiencing a strange problem with the Edge-Browser.
I'm using an ajax-call to login a user. As long as the user is in the same window, the session vars seem to be persistent.
But as soon as I open a new window (target="_blank") the session vars seem to be lost and the user isn't logged in anymore. The session vars are gone in the opening window as well.
I'm using this to set and get the session vars:
$sessionData = $GLOBALS['TSFE']->fe_user->getKey('ses', self::$prefixKey . $key);
$GLOBALS['TSFE']->fe_user->setKey('ses', self::$prefixKey . $key, $sessionData);
$GLOBALS['TSFE']->fe_user->storeSessionData();
It's happening in all versions of Edge - interestingly, for once it doesn't happen in IE.
Any ideas?
[Edit for clarification]: The new window is on the same domain as the opening one. No subdomains, no nothing.
Which version of Edge browser are you using? Please refer to the following steps to make sure you are not disabled cookies in Edge browser:
Open Edge browser, click on the More actions button in the top right
corner and select Settings.
Click View Advanced Settings. You’ll need to scroll down to the
bottom of the page.
Press the dropdown arrow under the Cookies field.
Select Don't block cookies.
If still not working, try to reset the Edge browser setting.
I'm implementing an invisible reCAPTCHA as per the instructions in the documentation: reCAPTCHA V2 documentation
I've managed to implement it without any problems. But, what I'd like to know is whether I can simulate being a robot for testing purposes?
Is there a way to force the reCAPTCHA to respond as if it thought I was a robot?
Thanks in advance for any assistance.
In the Dev Tools, open Settings, then Devices, add a custom device with any name and user agent equal to Googlebot/2.1.
Finally, in Device Mode, at the left of the top bar, choose the device (the default is Responsive).
You can test the captcha in https://www.google.com/recaptcha/api2/demo?invisible=true
(This is a demo of the Invisible Recaptcha. You can remove the url invisible parameter to test with the captcha button)
You can use a Chrome Plugin like Modify Headers and Add a user-agent like Googlebot/2.1 (+http://www.google.com/bot.html).
For Firefox, if you don't want to install any add-ons, you can easily manually change the user agent :
Enter about:config into the URL box and hit return;
Search for “useragent” (one word), just to check what is already there;
Create a new string (right-click somewhere in the window) titled (i.e. new
preference) “general.useragent.override”, and with string value
"Googlebot/2.1" (or any other you want to test with).
I tried this with Recaptcha v3, and it indeed returns a score of 0.1
And don't forget to remove this line from about:config when done testing !
I found this method here (it is an Apple OS article, but the Firefox method also works for Windows) : http://osxdaily.com/2013/01/16/change-user-agent-chrome-safari-firefox/
I find that if you click on the reCaptcha logo rather than the text box, it tends to fail.
This is because bots detect clickable hitboxes, and since the checkbox is an image, as well as the "I'm not a robot" text, and bots can't process images as text properly, but they CAN process clickable hitboxes, which the reCaptcha tells them to click, it just doesn't tell them where.
Click as far away from the checkbox as possible while keeping your mouse cursor in the reCaptcha. You will then most likely fail it. ( it will just bring up the thing where you have to identify the pictures).
The pictures are on there because like I said, bots can't process images and recognize things like cars.
yes it is possible to force fail a recaptcha v2 for testing purposes.
there are two ways to do that
First way :
you need to have firefox browser for that just make a simple form request
and then wait for response and after getting response click on refresh button firefox will prompt a box saying that " To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier. " then click on "resend"
by doing this browser will send previous " g-recaptcha-response " key and this will fail your recaptcha.
Second way
you can make any simple post request by any application like in linux you can use curl to make post request.
just make sure that you specify all your form filed and also header for request and most important thing POST one field name as " g-recaptcha-response " and give any random value to this field
Just completing the answer of Rafael, follow how to use the plugin
None of proposed answers worked for me. I just wrote a simple Node.js script which opens a browser window with a page. ReCaptcha detects automated browser and shows the challenge. The script is below:
const puppeteer = require('puppeteer');
let testReCaptcha = async () => {
const browser = await puppeteer.launch({ headless: false });
const page = await browser.newPage();
await page.goto('http://yourpage.com');
};
testReCaptcha();
Don't forget to install puppeteer by running npm i puppeteer and change yourpage.com to your page address
Part of the functionality of my intranet application is that a user needs to see some XML which has been generated. A new browser tab is opened, and the WebAPI controller streams XML.
This works fine, problem is when the user clicks on "Save As...", nothing happens.
If I place a static xml file on the server, browse to it and click "Save As..." then this works fine; so I don't see this as being caused by a group policy or desktop build error. This also works fine in a proper web browser.
The code to return the xml...
return new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new StringContent(fpml, Encoding.UTF8, "text/xml"),
};
If you trick IE into thinking that it has a file, rather than dynamic content, then the "Save As..." feature will work as expected.
This can be done by simply adding a filename into the URL, i.e.
Instead of
http://myhost/myapp/api/getFpmlApi/?TradeId=234234
use
http://myhost/myapp/api/getFpmlApi/Fpml.xml?TradeId=234234
on my web application, after clicking a download button, a popup message with content "Do you want to open or save "abc.txt" from this site?" with 3 buttons ("Open", "Save" & "Cancel") will be displayed at the bottom of page.
I'm trying to close/quit this browser session with below codes:
#driver.execute_script "window.onbeforeunload = function(e){};"
#driver.quit
However, the browser is NOT (but should be) closed. I'm working with Selenium Ruby Webdriver. Please guide me a way to resolve this problem. Thanks so much.
Note that with the above codes, I'm able to close IE9 browser that has the popup message "This page is asking you to confirm that you want to leave - data you have entered many not be saved" with "Leave Page" and "Stay on Page" buttons successfully. But, codes do NOT work in case the popup message with content "Do you want to open or save "abc.txt" from this site?" with 3 buttons ("Open", "Save" & "Cancel") displayed.
WebDriver has no control over these types of "Save file" dialog prompts.
Please peruse this article on this subject (note, his examples are in Java, but they can all be ported easily and with less code in Ruby). http://ardesco.lazerycode.com/index.php/2012/07/how-to-download-files-with-selenium-and-why-you-shouldnt/
Thus, I would recommend not even clicking the link in question and trying to deal with the dialog. Instead, grab the href value and initiate a Net::HTTP request to it like this SO response shows you how to do: https://stackoverflow.com/a/4581116/1221475 . You can then check the file for correct contents and such using standard Ruby and file parsers.
This is a hack by Dave Haefner. It is written for Java/Selenium combination, but you can easily convert it to Ruby syntax.
If you don't care if a file was downloaded or not and you want to confirm only that a file can be downloaded, you can use an HTTP request. Instead of downloading the file you'll receive the header information for the file which contains things like the content type and length. With this information, you can confirm the file is you expect.
String link = driver.findElement(By.cssSelector("download-link-element")).getAttribute("href");
HttpClient httpClient = HttpClientBuilder.create().build();
HttpHead request = new HttpHead(link);
HttpResponse response = httpClient.execute(request);
String contentType = response.getFirstHeader("Content-Type").getValue();
int contentLength = Integer.parseInt(response.getFirstHeader("Content-Length").getValue());
assertThat(contentType, is("application/octet-stream"));
assertThat(contentLength, is(not(0)));
I'd like to extend my WatiN automated tests to drive a page that guards against the user accidentally leaving the page without saving changes.
The page uses the "beforeunload" technique to seek confirmation from the user:
$(window).bind('beforeunload', function (event) {
if (confirmationRequired) {
return "Sure??";
}
});
My WatIn test is driving the page using IE. I cannot find a way to get WatIn to attach to the popup dialog so I can control it from my test.
All the following have failed (where the hard-coded strings refer to strings that I can see on the popup):
Browser.AttachTo<IE>(Find.ByTitle("Windows Internet Explorer");
browser.HtmlDialog(Find.FindByTitle("Windows Internet Explorer));
browser.HtmlDialog(Find.FindByTitle("Are you sure you want to leave this page?));
browser.HtmlDialog(Find.FindFirst());
Thanks!
You'll need to create and add the dialog handler.
Example Go to example site, click link, click leave page on confirmation dialog:
IE browser = new IE();
browser.GoTo("http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/refs/onbeforeunload.htm");
WatiN.Core.DialogHandlers.ReturnDialogHandlerIe9 myHandler = new WatiN.Core.DialogHandlers.ReturnDialogHandlerIe9();
browser.AddDialogHandler(myHandler);
browser.Link(Find.ByUrl("http://www.microsoft.com")).ClickNoWait();
myHandler.WaitUntilExists();
myHandler.OKButton.Click();
browser.RemoveDialogHandler(myHandler);
The above is working on WatiN2.1, IE9, Win7. If using IE8 or before, you will likely need to use the ReturnDialogHandler object instead of the Ie9 specific handler
