I am trying to access a website that requires a login thru an alert box such as the one below:
I have tried to look up many different ways to do this and they dont seem to work. what i have tried are listed below:
Didnt work and gave me the same login alert.
start_url = 'http://username:password#example.com'
agent.get(start_url)
Keep getting an error message saying "NoAlertPresentException: Message: no alert open"
start_url = 'http://www.example.com'
alert = agent.switch_to_alert()
alert.send_keys("username")
alert.send_keys("password")
Get an error saying webdriver has no attribute "switchTo"
start_url = 'http://www.example.com'
agent.switchTo().alert().sendKeys("username")
I have to use Chrome because of the versions of IE and Firefox I have and can get, do not support the functions in the site
I have been having this exact same issue for some time now - with my end goal being to do this headless (in the background without visually launching an instance of Chromedriver).
Non-Ideal Solution 1:
I first used a library called pynput to automatically type the credentials in to the alert box and click the ok button, it was pretty simple to get working but:
still didn't work headlessly
I had to be focused on the browser or it would type the credentials elsewhere
This worked great in the meantime as everywhere I looked online it seemed like there was nothing I could do to overcome authentication alerts headlessly...
I'm a relative beginner (started programming <1 year ago) so perhaps I just wasn't looking in the right places!
I've now solved this issue though like so:
First I logged in to the alert as normal on Chrome while monitoring the Network section of devtools to get a good look at the GET request for the protected page screencap here:
Upon seeing that the Authorization was Basic (this will work for Bearer too) I tested just copying the same request in Postman with this header and it worked! Now if only there was a way to make http requests from Selenium???
I first tried the library selenium-requests (which didn't work for me: I got the same error as this person https://github.com/cryzed/Selenium-Requests/issues/33
This library seems absolutely excellent and exactly what I needed, I just don't currently have the know-how to get past firewalls/whatever was stopping me at this stage...
What eventually worked for me was the library selenium-wire. I followed this guide https://pypi.org/project/selenium-wire/#intercepting-requests-and-responses to have the webdriver navigate to the protected page as normal, but intercept the request and add the Authorization header before sending it :) now this works for me totally headlessly. Granted, this won't work on more secure websites but I hope it helps someone having the same issue.
This is Pythoncode
Problem with alert boxes (especially sweet-alerts is that they have a
delay and Selenium is pretty much too fast)
An Option that worked for me is: (just exchange the button click in the end with whatever action you want to have)
while True:
try:
driver.find_element_by_xpath('//div[#class="sweet-alert showSweetAlert visible"]')
break
except:
wait = WebDriverWait(driver, 1000)
confirm_button = driver.find_element_by_xpath('//button[#class="confirm"]')
confirm_button.click()
Note to 2: Here is probably the error due to the alert taking more time to load than the single elements (such as username, etc.)
Note to 3.: I think it should be switch_to
Build time of XPages application containing several JARs, Java sources and ~50 XP/CC elements takes about minute to build on server via WAN. I have replicated application to local, build time dropped to ~10s.
Since few days ago build of local application is extremely slow, about 2-5 minutes. After some experiments there is workaround: to disable TCP port in location document - it drops build times to just few seconds. Even tho it works, it does not help much - testing requires user to be authenticated, so I need to replicate design changes to remote or local server - and that means to change location (online/offline) every time.
UPDATE 2013-04-04: I have duplicated my current location document and removed home and directory servers. To my surprise, with this location build times went back to few seconds - with TCP port enabled so replication is possible. Bigger surprise was the fact, that returning home/directory servers back to new location did not reproduce the problem - in fact they do not affect performance. I know it because I have renamed current location document and everything went to normal. From my understanding, "something" in client configuration was connected to location name. Thanks to Simon's tips I will investigate further.
The question is still open: I am looking for some (eclipse) preference controlling this behavior - unintended communication with server during build of local application.
Solution:
Teamstudio CIAO hooks into designer and checks for every update of design element. Seems to be lack of code optimization to me: it checks whether currently built design element (every single one, one by one) should be controlled in CIAO config database.
This explains why the problem was solved by renaming of location document. I was disappointed yesterday, when performance problems started again. Fortunately, I recalled CIAO setup to that location document about that time. CIAO uses teamstudio.ini file in DATA directory to configure what CIAO configuration database is used for every location document. Look for entry:
CIAOConfigDb[location name]=server name;CIAO\CIAOConfig.nsf
For development on local replicas with connection to server (for replication or local server), use location document with CIAO disabled.
This works only with property ForceConfigLocation=0.
Not a solution (yet!), but may help in the investigation. I'll update further if you post results later.
Debug instructions.
Add the following to the shortcut that launches the Designer client.
-RPARAMS -console -debug -separateSysLogFiles -consoleLog
Start the designer client. This will also open up the OSGi console.
Reproduce the issue. While it is still in progress in the OSGi console type the following:
dump threads
Do this three times, with a small amount of time between completion of each dump. Once done open the three heap dumps (in the IBM_TECHNICAL_SUPPORT folder) in the Heap Dump Analyser.
It will show you what threads are consistent through all three dumps. Take a look at those and look for package names/calls which may appear to be a functional area. Once you have that then you can try adding the debug for the related class.
For example: Let's say you notice "com.ibm.designer.domino.ui.commons." in the thread, then you would edit the rcpinstall.properties file. It will be in:
<Notes Install>\Data\workspace\.config\rcpinstall.properties
and you would add (start with FINE, then FINEST if nothing):
com.ibm.designer.domino.ui.commons.level=FINE
Now when you restart the designer client it will generate debug output in the workspace\logs folder for that package. You need to then go through the trace logs looking for the time when the delay occurred and see if it makes any references to related design elements.
Other open applications may get built at the same time (which looks like a bug top me). Be sure to close all other applications and the server based replica. Open applications have their icon showing in the application list and they stay open even if you close and reopen the Designer. In Designer 9 right click application and select "Close Application". In 8.5 you need to use Package Exprorer for closing.
Another good way is to use Working Sets. Only applications in open Working Set will be built (AFAIK). Have a Working Set with this one app only (and the app only in this Working Set).
update 1
If these don't help I would delete/rename bookmark.nsf, Cache.NDK and desktop8.ndk. Then open just this one app and see what happens.
update 2
Check that there are no referenced projects. Right click the application and select "Project Properties". From there "Project Referencies" and make sure no check boxes are checked.
update 3
Based on your update I would check the item names starting with $ in location document. Sometimes there are saved IP addresses etc. which could cause this problem. All those items can be removed.
If possible (and if You are not using it yet) try to use version 9 of the Domino designer (You do not have to use Domino 9 to do that - it works fine with Domino 8.5.3).
For our projects build times went down to only few seconds from few minutes. I guess that they finally noticed at IBM that the build process used to heavily relay on connection to server and done something with it.
With new designer You don't event have to replicate to local. You can directly work on Your local server.
I want to test air applications and air libraries using flexmojos 3.9-SNAPSHOT.
However, although flexmojos does indeed has support for air, it tries to run the swf generated by the build using flash player, and as I need to use air native libraries I wanted to run the tests using adl (AIR debug launcher).
To do this, I cloned flexmojos in github.com to this repository (http://github.com/mi007/flexmojos). I then created a class that created an -app.xml for the TestRunner.swf file that was generated and ran:
adl TestRunner-app.xml
However, before the Test ends, it should call the server in the port 13540 to report something. When that happens, I'm getting the following error:
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: app:/TestRunner.swf cannot load data from 127.0.0.1:13540.

I know that it is calling the server before in port 13539 successfully, because it prints the test results on the console. I also know that it is opening port 13540 because I was able to telnet to it. However, for some reason it is unable to connect from the air application.
Given the circunstances, I have the following questions:
1) Is there any good documentation that I can read to understand how this security framework works? The only documentation that I found was terribly confusing.
2) Does anyone has any ideas or hints about what might be happening?
3) I have read somewhere that flexmojos hacks the security framework so that flex applications can open a socket to localhost without problems during tests. Is there any documentation about how this is done?
Thanks,
You've got very close to the answer in your comment...
You need to add a line to a file in ~/Library/Preferences/Macromedia/Flash Player/#Security/FlashPlayerTrust yourself, covering the swf you want to run. You can do this by hand directly (all files in that folder will be processed) or by using the Flash Player Settings Manager.
I have some 'spaghetti'-style code that is generously saused with Custom tags and Stored procedures calls. Templates include each other, custom tags nested and stored procedures are callind other stored procedures in their place.
Problem is that one template call is hanging somewhere in between. I cannot get any error out and cannot see debug output. What is best way to debug such 'hanging' request with as much detail as possible ?
Thanks!
If you are using CF 8+, you can use the Step Debugging tools in Eclipse to step through the code: http://www.adobe.com/devnet/coldfusion/articles/debugger.html
If you are using an earlier version, you can use a 3rd party product like Fusion Debug ( http://www.fusion-debug.com/fd/ ) to do the same thing.
If you are using CF8, you can also use the CF Admin Server Monitor to see where a thread is hanging as well: http://www.adobe.com/devnet/coldfusion/articles/monitoring_pt1.html
If the built-in debugger is of no use cause the request just hang the other quick way is to just start with a cfabort at the top and keep moving it down until you hit the file causing the request to hang.
CFTrace is a great tool for this. It is native and reports time information as well.
Have you looked at the standard coldfusion server log files to see what might be in there?
Have you run the server in a console window so you can see what is appearing in the console as the templates are running (or not as the case might be)?
You could Take jvm thread dumps. You can do from command line or via server monitoring if you have Enterprise 8+
Trying to honor a feature request from our customers, I'd like that my application, when Internet is available, check on our website if a new version is available.
The problem is that I have no idea about what have to be done on the server side.
I can imagine that my application (developped in C++ using Qt) has to send a request (HTTP ?) to the server, but what is going to respond to this request ? In order to go through firewalls, I guess I'll have to use port 80 ? Is this correct ?
Or, for such a feature, do I have to ask our network admin to open a specific port number through which I'll communicate ?
#pilif : thanks for your detailed answer. There is still something which is unclear for me :
like
http://www.example.com/update?version=1.2.4
Then you can return what ever you want, probably also the download-URL of the installer of the new version.
How do I return something ? Will it be a php or asp page (I know nothing about PHP nor ASP, I have to confess) ? How can I decode the ?version=1.2.4 part in order to return something accordingly ?
I would absolutely recommend to just do a plain HTTP request to your website. Everything else is bound to fail.
I'd make a HTTP GET request to a certain page on your site containing the version of the local application.
like
http://www.example.com/update?version=1.2.4
Then you can return what ever you want, probably also the download-URL of the installer of the new version.
Why not just put a static file with the latest version to the server and let the client decide? Because you may want (or need) to have control over the process. Maybe 1.2 won't be compatible with the server in the future, so you want the server to force the update to 1.3, but the update from 1.2.4 to 1.2.6 could be uncritical, so you might want to present the client with an optional update.
Or you want to have a breakdown over the installed base.
Or whatever. Usually, I've learned it's best to keep as much intelligence on the server, because the server is what you have ultimate control over.
Speaking here with a bit of experience in the field, here's a small preview of what can (and will - trust me) go wrong:
Your Application will be prevented from making HTTP-Requests by the various Personal Firewall applications out there.
A considerable percentage of users won't have the needed permissions to actually get the update process going.
Even if your users have allowed the old version past their personal firewall, said tool will complain because the .EXE has changed and will recommend the user not to allow the new exe to connect (users usually comply with the wishes of their security tool here).
In managed environments, you'll be shot and hanged (not necessarily in that order) for loading executable content from the web and then actually executing it.
So to keep the damage as low as possible,
fail silently when you can't connect to the update server
before updating, make sure that you have write-permission to the install directory and warn the user if you do not, or just don't update at all.
Provide a way for administrators to turn the auto-update off.
It's no fun to do what you are about to do - especially when you deal with non technically inclined users as I had to numerous times.
Pilif answer was good, and I have lots of experience with this too, but I'd like to add something more:
Remember that if you start yourapp.exe, then the "updater" will try to overwrite yourapp.exe with the newest version. Depending upon your operating system and programming environment (you've mentioned C++/QT, I have no experience with those), you will not be able to overwrite yourapp.exe because it will be in use.
What I have done is create a launcher. I have a MyAppLauncher.exe that uses a config file (xml, very simple) to launch the "real exe". Should a new version exist, the Launcher can update the "real exe" because it's not in use, and then relaunch the new version.
Just keep that in mind and you'll be safe.
Martin,
you are absolutely right of course. But I would deliver the launcher with the installer. Or just download the installer, launch it and quit myself as soon as possible. The reason is bugs in the launcher. You would never, ever, want to be dependent on a component you cannot update (or forget to include in the initial drop).
So the payload I distribute with the updating process of my application is just the standard installer, but devoid of any significant UI. Once the client has checked that the installer has a chance of running successfully and once it has downloaded the updater, it runs that and quits itself.
The updater than runs, installs its payload into the original installation directory and restarts the (hopefully updated) application.
Still: The process is hairy and you better think twice before implementing an Auto Update functionality on the Windows Platform when your application has a wide focus of usage.
in php, the thing is easy:
<?php
if (version_compare($_GET['version'], "1.4.0") < 0){
echo "http://www.example.com/update.exe";
}else{
echo "no update";
}
?>
if course you could extend this so the currently available version isn't hard-coded inside the script, but this is just about illustrating the point.
In your application you would have this pseudo code:
result = makeHTTPRequest("http://www.example.com/update?version=" + getExeVersion());
if result != "no update" then
updater = downloadUpdater(result);
ShellExecute(updater);
ExitApplication;
end;
Feel free to extend the "protocol" by specifying something the PHP script could return to tell the client whether it's an important, mandatory update or not.
Or you can add some text to display to the user - maybe containing some information about what's changed.
Your possibilities are quite limitless.
My Qt app just uses QHttp to read tiny XML file off my website that contains the latest version number. If this is greater than the current version number it gives the option to go to the download page. Very simple. Works fine.
I would agree with #Martin and #Pilif's answer, but add;
Consider allowing your end-users to decide if they want to actually install the update there and then, or delay the installation of the update until they've finished using the program.
I don't know the purpose/function of your app but many applications are launched when the user needs to do something specific there and then - nothing more annoying than launching an app and then being told it's found a new version, and you having to wait for it to download, shut down the app and relaunch itself. If your program has other resources that might be updated (reference files, databases etc) the problem gets worse.
We had an EPOS system running in about 400 shops, and initially we thought it would be great to have the program spot updates and download them (using a file containing a version number very similar to the suggestions you have above)... great idea. Until all of the shops started up their systems at around the same time (8:45-8:50am), and our server was hit serving a 20+Mb download to 400 remote servers, which would then update the local software and cause a restart. Chaos - with nobody able to trade for about 10 minutes.
Needless to say that this caused us to subsequently turn off the 'check for updates' feature and redesign it to allow the shops to 'delay' the update until later in the day. :-)
EDIT: And if anyone from ADOBE is reading - for god's sake why does the damn acrobat reader insist on trying to download updates and crap when I just want to fire-it-up to read a document? Isn't it slow enough at starting, and bloated enough, as it is, without wasting a further 20-30 seconds of my life looking for updates every time I want to read a PDF?
DONT THEY USE THEIR OWN SOFTWARE??!!! :-)
On the server you could just have a simple file "latestversion.txt" which contains the version number (and maybe download URL) of the latest version. The client then just needs to read this file using a simple HTTP request (yes, to port 80) to retrieve http://your.web.site/latestversion.txt, which you can then parse to get the version number. This way you don't need any fancy server code --- you just need to add a simple file to your existing website.
if you keep your files in the update directory on example.com, this PHP script should download them for you given the request previously mentioned. (your update would be yourprogram.1.2.4.exe
$version = $_GET['version'];
$filename = "yourprogram" . $version . ".exe";
$filesize = filesize($filename);
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: post-check=0, pre-check=0");
header("Content-type: application-download");
header('Content-Length: ' . $filesize);
header('Content-Disposition: attachment; filename="' . basename($filename).'"');
header("Content-Transfer-Encoding: binary");
This makes your web browser think it's downloading an application.
The simplest way to make this happen is to fire an HTTP request using a library like libcurl and make it download an ini or xml file which contains the online version and where a new version would be available online.
After parsing the xml file you can determine if a new version is needed and download the new version with libcurl and install it.
Just put an (XML) file on your server with the version number of the latest version, and a URL to the download the new version from. Your application can then request the XML file, look if the version differs from its own, and take action accordingly.
I think that simple XML file on the server would be sufficient for version checking only purposes.
You would need then only an ftp account on your server and build system that is able to send a file via ftp after it has built a new version. That build system could even put installation files/zip on your website directly!
If you want to keep it really basic, simply upload a version.txt to a webserver, that contains an integer version number. Download that check against the latest version.txt you downloaded and then just download the msi or setup package and run it.
More advanced versions would be to use rss, xml or similar. It would be best to use a third-party library to parse the rss and you could include information that is displayed to your user about changes if you wish to do so.
Basically you just need simple download functionality.
Both these solutions will only require you to access port 80 outgoing from the client side. This should normally not require any changes to firewalls or networking (on the client side) and you simply need to have a internet facing web server (web hosting, colocation or your own server - all would work here).
There are a couple of commercial auto-update solutions available. I'll leave the recommendations for those to others answerers, because I only have experience on the .net side with Click-Once and Updater Application Block (the latter is not continued any more).
