I'm trying to program a script for hubot, and it seems I have an unclosed string. The contents will appear in an html format with emoji like :smile: etc. It isn't compiling in Cofeescript. I'm new to javascript, any help would be appreciated.
The error I got is
ERROR Unable to load /var/discourse/avebot/scripts/test: /var/discourse/avebot/scripts/test.js:5
msg.reply("Hello! I’m Avebot, and I will be your guide throughout your training. :smile: <br>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: Invalid or unexpected token
at new Script (vm.js:51:7)
and the script is:
robot.hear(/hi bot/, function(msg) {
msg.reply("Hello! I’m a bot, and I will be your guide your training. :smile: <br>
<br>After finishing this training, you will be able to do x y z. :tada:<br>
Are you ready? If so, let me know you are ready by replying 'yes I’m ready!'");
//Start a dialog with the user that sent this message.
var dialog = switchBoard.startDialog(msg);
//Provide choices for the next step, wait for the user.
dialog.addChoice(/yes/, function(msg2){ msg2.reply('Okay');}
dialog.addChoice( /no/, function(msg2){ msg2.reply("Okay, I'll wait"); }
//The dialog will expire after 30 secods.
});
You need to escape the ' in I'm Avebot by putting a backslash before the apostrophe (so it's I\'m Avebot).
Check out this site here for more information on JS escape sequences.
in order to define multiline strings in Javascript you can use backslash \ before new lines
msg.reply("Hello! I’m a bot, and I will be your guide your training. :smile: <br>\
<br>After finishing this training, you will be able to do x y z. :tada:<br>\
Are you ready? If so, let me know you are ready by replying 'yes I’m ready!'");

I'm new to Nim, but it appears that there is no way to get input from the console in a similar way to input() in python or Console.ReadLine() in dotnet.
I want execution of my code to pause, wait for input, then on pressing enter to continue (just like input in other langs).
Oh no never mind found it:
var consoleInput = readLine(stdin);
I am making a custom discord bot in python. I am trying to add a !report command.
I am very confused and cant find the answer anywhere. Can anyone help me make it?
I want any user to be able to do !report #example reason.
and save it in a database such as excel or sql3 or preferably in a staff channel.
how would I do this?
I have tried to use on_message()
You could use the on_message() command:
#client.event
async def on_message(message):
if message.content.startswith("!report"):
report_channel = client.get_channel(channel id)
member = text.split(" ")[1]
reason = ' '.join(text.split(" ")[1:])
await report_channel.send(f"Member: {member}, Reason: {reason}")
So the first thing is to look to see if the person used the "!report" command with an if statement.
Next, you find the member by taking the second word of the message.
After that, you find the reason by taking the rest of the words in the message.
Then you send it to the pre-defined report channel on discord.
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.
I am pretty new to web-scraping and recently I am trying to automatically scrap phone number for pages like this. I am not supposed to use Selenium/headless url browser libraries and I am trying to find the a way to actually request the phone number using let say a web service or any other possible solution that could give me the phone number hopefully directly without having to go through the actual button press by selenium.
I totally understand that it may not even be possible to automatically reveal the phone number in one shut as it is meant not be accessible by nosy newbie web-scraper like me; but I still like to raise the question for my information to get detailed answer from an expert point of view.
If I search the "Reveal" button DOM element, it shows some tags which I have never seen before. I have two main questions which I believe could be helpful for newbies like me.
1) Given a set of unknown tags/attribues (ie. data-q and data-reveal in the blow button), how is one able to find out which scripts in the page are actually using them?
2) I googled the button element's tag like: data-q and data-reveal the only relevant I could find was this which for some reason I don't have access two even-if I use proxy.
Any clue particularly on the first question is much appreciate it.

Below is the href-button code
Reveal
Ok, according to your demand there are several steps before you finally get a solution.
1st step : open your own browser and enter your target page(https://www.gumtree.com/p/vans/2015-ford-transit-custom-2.2tdci-290-l1-h1/1190345514)
2nd step : (Assume you are using Chrome as your favorite browser) Press Ctrl+Shift+I to open the console, and then select 'Network' tag in the console.
3rd step : Press the 'Reveal' button on that page, watch the console carefully, catch the http request which is sent immediately when you press the 'Reveal' button. You can see the request contains a long string of number in Query String Parameters, actually it is a timestamp.
4th step : Also you can see there is a part named 'Request Headers' in that http request, and you should copy the values of referer , user-agent , x-gumtree-token.
5th step : Try to construct your request (I am a fan of Python, So I am going to show you my example code in Python)
import time
import requests
import json
headers = {
'referer': 'please enter the value you just copied from that specific request',
'user-agent': 'please enter the value you just copied from that specific request',
'x-gumtree-token': 'please enter the value you just copied from that specific request'
}
url = 'https://www.gumtree.com/ajax/account/seller/reveal/number/1190345514?_='
current_time = time.time()
current_time = str(current_time)
current_time = current_time.split('.')[0] + current_time.split('.')[1] + '0'
url += current_time
response = requests.get(url=url,headers=headers)
response_result = json.loads(response.content)
phone_number = response_result['data']
So I've built a Telegram bot, which can receive the following commands:
/list
/info 123
This works great, as I can catch /info and pass the additional arguments as ints. But, sadly, the Telegram clients don't see /info 123 as a complete command, but just the /info part. Is there a way to make it recognize the entirety of the command as the command?
I've tried Markdown-ing it: [/info 123](/info 123), but no joy. Is this possible?
I've reached out to #BotSupport with the same question, and he/they/it responded swiftly with the following answer:
Hi, at the moment it is not possible to highlight parameters of a command. I any case, you may can find a workaround if you use correct custom keyboards ;)
— #BotSupport
Custom keyboards may be an option for someone, but not for me. The solution I've gone for is to give the command as /info123. As the bot receives all / commands, I check if the received command starts with info, and if so, I remove the info part. I convert the remaining string/int to arguments, and pass that along to the relevant command.
If you mean to pass the 123 as an argument for your command info and if you happen to use the python-telegram-bot, then here's how you do it:
dispatcher.add_handler(CommandHandler('hello', SayHello, pass_args=True))
According to the documentation: pass_args Determines whether the handler should be passed the arguments passed to the command as a keyword argument called args. It will contain a list of strings, which is the text following the command split on single or consecutive whitespace characters. Default is False.
you can use RegexHandler() to do this.
Here is an example
def info(bot, update):
id = update.message.text.replace('/info_', '')
update.message.reply_text(id, parse_mode='Markdown')
def main():
updater = Updater(TOKEN)
updater.dispatcher.add_handler(RegexHandler('^(/info_[\d]+)$', info))
updater.start_polling()
Usage
The command /info_120 will return 120
and /info_007 will return 007
UPDATE
for newer versions, you may use this method instead!
MessageHandler(filters.Regex(r'^(/info_[\d]+)$'), info)
To get the argument of command you don't even need to use pass_args as said Moein you can simply get it from context.args look at Github page. So you can pass as many arguments as you want and you will get a list of arguments! Here is an example from Github.
def start_callback(update, context):
user_says = " ".join(context.args)
update.message.reply_text("You said: " + user_says)
...
dispatcher.add_handler(CommandHandler("start", start_callback))
ForceReply
Upon receiving a message with this object, Telegram clients will display a reply interface to the user (act as if the user has selected the bot's message and tapped 'Reply'). This can be extremely useful if you want to create user-friendly step-by-step interfaces without having to sacrifice privacy mode.
a simple shot
In this case, a user should send a valid number with /audio command (e.g. /audio 3, if they forgot it, we can inform and force them to do so.

This is a fairly rudimentary way of creating kwargs from user input.
Unfortunately, it does require the user to be aware of the fields that can be used as parameters, but if you can provide informative response when the user doesnt provide any detectable kwarg style messages then you could probably make a better experience.
As I say, extremely rudimentary idea, and would probably be achieved faster with the regex filters available. And this would be much more reliable when checking input from the user of the "pesky" variety.
The script relies on || delimiter preceeding the command and as is shown will trim any extra characters like new lines and spaces
You can remove the extra check for commit as this is provided in order to tell the bot that you want to save your input to the database explicitly.
def parse_kwargs(update):
commit = False
kwargs = {}
if update.message:
for args in update.message.text.split('||')[1:]:
for kw_pair in args.split(','):
key, value = kw_pair.split('=')
if key.strip() != 'commit':
kwargs[key.strip()] = value.strip()
elif key.strip() == 'commit' and value.strip().lower() == 'true':
commit = True
return kwargs, commit
