Aiogram. How to send message without sound? - telegram

I can send message without sound. Can bot send message without sound using Aiogram?

Yes, Aiogram supports the disable_notification option.
For example, on a reply[docs] on /start:
#dp.message_handlers(commands=['start'])
async def welcome(message: types.Message):
await message.reply(text="No sound!", disable_notification=True)

How to send external messages to a specific channel with discord py?

I'm trying to forward messages to channel when I receive messages from api.
I'm using
def trigger(messagecontent):
async def messagesender():
channel = ... #get channel id
await channel.send(messagecontent)
await bot.close()
#bot.event
async def on_ready():
await messagesender()
bot.run(token=Token)`
What happens is, when I receive message from api, I call trigger(messagecontent), the bot logs in, sends message and closes, then the rest of my external script (sync version) executes.
But on the next loop, when new message from api is received, trigger(messagecontent) gives error
Runtime: Session is closed
If I don't close the bot with bot.close(), my sync script will be stuck at discord part. This is why I need to close the bot.
I don't want to use webhooks because there are many channels where messages are to be sent using the same bot.
Why are you shutting down the bot via await bot.close()?
Ofc you will get that error if you shut down the bot.

SSE with Leshan LWM2M Demo Server

I am trying to do an http api that interact with a Leshan Demo Server.
I was trying to handle the OBSERVE in LWM2M, but I need to handle the notification with http.
I discovered that leshan notify using SSE. So I was trying to implement the sse client in python using requests and sseclient.
This is my code:
response= requests.post(url_request , "format=TLV" , stream= True)
client = sseclient.SSEClient(response)
for event in client.events():
print(json.loads(event.data))
I tried to run my script but it seems like the stream is not opening and it close immediately without waiting for the answer of the server, even if requests by default implement keep_alive for TCP connection under HTTP and the stream is True.
Does someone know why?
Reading the sseclient documentation, the correct way so use SSEClient seems to be :
from sseclient import SSEClient
messages = SSEClient('http://example.com/sse_stream/')
for msg in messages:
do_something_useful(msg)
Reading the answer on Leshan Github, the stream URL for Leshan Server Demo seems to be http://your.leshan.server.org/event?ep=your_device_endpoint_name
So I tried that :
from sseclient import SSEClient
messages = SSEClient('http://localhost:8080/event?ep=my_device')
for msg in messages:
print (msg.event, msg.data)
And it works for me 🎉 ! Getting this kind of results when I observe the temperature instance of Leshan Client Demo :
(u'NOTIFICATION', u'{"ep":"my_device","res":"/3303/0","val":{"id":0,"resources":[{"id":5601,"value":-18.9},{"id":5602,"value":31.2},{"id":5700,"value":-18.4},{"id":5701,"value":"cel"}]}}')

If you are interested by notification only, just add a if msg.event == 'NOTIFICATION': block.

Where should I upload my telegram bot's code to run?

I know I create new bot, give it name, description from BotFather inside telegram
But this only adds the bot, when I modify my bot, code some functionality in python\lua\php etc - where should the code go and how telegram will know the behavior of my bot?
Who runs the new code, where should I upload my new additional code for my bot?
Does it go to telegram server and runs there on the cloud?
If so, how to upload it?
After you have setup your Bot's identity (#bot_name) with BotFather, the next step is to design the interaction/functions your Bot will perform.
Your bot code lives on YOUR server.
Requests from users interacting with your #bot_name will be routed from Telegram to your servers which ...
1) you have setup with a webHook (using the setWebhook method) so Telegram knows where to send your bot's requests
or
2) your bot polls Telegram's Bot-API repeatedly asking if there are any new updates (i.e. messages users sent to your bot) using the getUpdates method
Your bot receives these messages, and replies as directed by your bots "code or logic"
hope this helps.
You can run the code quite easily from your machine.
For example how I did it using NodeJS:
1)Install NodeJS on your machine (details - https://nodejs.org/en/download/package-manager/)
2)Install Node Telegram Bot API (https://github.com/yagop/node-telegram-bot-api)
3) create a file like this, filling in with necessary changes:
const TelegramBot = require('node-telegram-bot-api');
// replace the value below with the Telegram token you receive from #BotFather
const token = 'YOUR_TELEGRAM_BOT_TOKEN';
// Create a bot that uses 'polling' to fetch new updates
const bot = new TelegramBot(token, {polling: true});
// Matches "/echo [whatever]"
bot.onText(/\/echo (.+)/, (msg, match) => {
// 'msg' is the received Message from Telegram
// 'match' is the result of executing the regexp above on the text content
// of the message
const chatId = msg.chat.id;
const resp = match[1]; // the captured "whatever"
// send back the matched "whatever" to the chat
bot.sendMessage(chatId, resp);
});
// Listen for any kind of message. There are different kinds of
// messages.
bot.on('message', (msg) => {
const chatId = msg.chat.id;
// send a message to the chat acknowledging receipt of their message
bot.sendMessage(chatId, 'Received your message');
});
4) Finally launch your command console (like cmd on Windows) navigate to telegram bot directory where the script is located and type node index.js (assuming your file with the bot script like above is named index.js)
Following these steps you will have a fully functioning bot. As you make changes to index.js you can simply rerun the command "node index.js" in console.
The procedure is similar if you need to set up a bot on a server.
Hope this helps.

Telegram Inline Bot not call webhook

I've created new bot for Telegram. I've set /setinline in BotFather for my bot. I've added a webhook that is called when I send a message to bot but this webhook is not called if I write something in the bot chat without send any message.
Any idea how to solve?
Yes, it does, probably you're inspecting the wrong param, it will call the same webhook, first remember you set the webhook by doing:
https://api.telegram.org/bot<BOT_TOKEN>/setWebhook?url=<YOUR_URL>
and like you mentioned, you need to enable /setinline through BotFather, then it will call your endpoint with a message with the following body:
{
"query":"tex",
"from": {
"username":"user",
"first_name":"firstname",
"last_name":"lastname",
"id": 8888888,
"language_code":"en-US"},
"id":"7777777",
"offset":""
}
Remember it will call your endpoint on key-up you may receive a ton of request.

Why can't I defer sending a message for a one-way client

What is the rationale behind the following exception when trying to Defer the sending of a message on a one-way client:
System.InvalidOperationException "Cannot use ourselves as timeout manager because we're a one-way client"
A one-way client is a Rebus client that is not capable of receiving messages, so it has no input queue.
The way await bus.Defer(...) works, is by sending a message with some special headers to a "timeout manager", which by default is the endpoint that defers the message.
But since a one-way client has no input queue, it has no place to send the deferred message to.
You can make a one-way client defer messages by configuring an external timeout manager like this:
Configure.With(...)
.(...)
.Options(o => o.UseExternalTimeoutManager(anotherQueue))
.Start();
which will then cause the client to send the deferred message to that queue.
Moreover, you would have to manually set the rbs2-defer-recipient header to some other input queue, so that the timeout manager knows where to send the message when it is time to be consumed(*).
I hope that explains it :) please let me know if it is not clear.
*) This is actually not the case with Rebus 4, because bus.Defer uses the normal endpoint mappings to route messages.
If Rebus.AzureServiceBus is used there is more simple (or hacky) way to send delayed messages.
You have to specify 2 headers: rbs2-deferred-until and rbs2-defer-recipient and call Publish method like in the example.
var deferredUntil = DateTimeOffset.UtcNow.AddDays(1);
var headers = new Dictionary<string, string>();
headers.Add(Headers.DeferredUntil, deferredUntil.ToString("O", CultureInfo.InvariantCulture));
headers.Add(Headers.DeferredRecipient, #"Rebus requires this ¯\_(ツ)_/¯");
await bus.Publish(new SomeMessage(), headers);
Note: rbs2-defer-recipient is required by Rebus so any dummy values are okay.
Be careful, it looks like a workaround so it may not work after Rebus.AzureServiceBus update. It works for me in 5.0.1.
