问题
I would like to be able to send a message to a group chat in Telegram. I want to run a python script (which makes some operations that already works) and then, if some parameters have some values the script should send a message to a group chat through Telegram. I am using Ubuntu, and Python 2.7
I think, if I am not wrong, that I have two ways to do that:
Way One: make the Python script connect to the Telegram APIs directly and send the message (https://core.telegram.org/api).
Way Two: make the Python script call the Telegram's CLI (https://github.com/vysheng/tg), pass some values to this and then the message is sent by the Telegram's CLI.
I think that the first way is longer, so a good idea might be using the Way Two.
In this case I really don't know how to proceed. I don't know lots about scripts in linux, but I tried to do this:
#!/bin/bash
cd /home/username/tg
echo "msg user#******** messagehere" | ./telegram
sleep 10
echo "quit" | ./telegram
this works at a half: it sends the message correctly, but then the process remains open. And second problem, I have no clue on how to call that from python and how to pass some value to this script. The value that I would like to pass to the script is the "messagehere" var: this would be a 100/200 characters message, defined from inside the python script.
Does anyone has any clues on that? Thanks for replies, I hope this might be useful for someone else.
回答1:
First create a bash script for telegram called tg.sh:
#!/bin/bash
now=$(date)
to=$1
subject=$2
body=$3
tgpath=/home/youruser/tg
LOGFILE="/home/youruser/tg.log"
cd ${tgpath}
${tgpath}/telegram -k ${tgpath}/tg-server.pub -W <<EOF
msg $to $subject
safe_quit
EOF
echo "$now Recipient=$to Message=$subject" >> ${LOGFILE}
echo "Finished" >> ${LOGFILE}
Then put the script in the same folder than your python script, and give it +x permission with chmod +x tg.sh
And finally from python, you can do:
import subprocess
subprocess.call(["./tg.sh", "user#****", "message here"])

Telegram recently released their new Bot API which makes sending/receiving messages trivial. I suggest you also take a look at that and see if it fits your needs, it beats wrapping the client library or integrating with their MTProto API.
import urllib
import urllib2
# Generate a bot ID here: https://core.telegram.org/bots#botfather
bot_id = "{YOUR_BOT_ID}"
# Request latest messages
result = urllib2.urlopen("https://api.telegram.org/bot" + bot_id + "/getUpdates").read()
print result
# Send a message to a chat room (chat room ID retrieved from getUpdates)
result = urllib2.urlopen("https://api.telegram.org/bot" + bot_id + "/sendMessage", urllib.urlencode({ "chat_id": 0, "text": 'my message' })).read()
print result
Unfortunately I haven't seen any Python libraries you can interact directly with, but here is a NodeJS equivalent I worked on for reference.

Since version 1.05 you can use the -P option to accept messages from a socket, which is a third option to solve your problem. Sorry that it is not really the answer to your question, but I am not able to comment your question because I do not have enough reputation.

I'm working with pytg which could be found here: A Python package that wraps around Telegram messenger CLI
it works pretty good. I already have a python bot based on that project
回答5:
You can use safe_quit to terminate the connection instead since it waits until everything is done before closing the connection and termination the application
#!/bin/bash
cd /home/username/tg
echo "msg user#******** messagehere\nsafe_quit\n" | ./telegram
use this as a simple script and call it from python code as the other answer suggested.
回答6:
I would recommend the first option.
Once you are comfortable with generating an AuthKey, you should start to get a handle on the documentation.
To help, I have written a detailed step-by step guide of how I wrote the AuthKey generation code from scratch here.
It's in vb.net, but the steps should help you do same in python.
