Is it possible to get the uid of anyone tagged in a message? (stored in the contentMetadata) - and if its not possible (i dont think it is) can it be added by any chance?

create an ubuntu 16.04 server running a LAMP stack (from DigitalOcean)
link the domain name doodspav.com to the server

update and install pip
$ sudo apt-get update && sudo apt-get -y upgrade
$ sudo apt-get install python-pip
$ pip install --upgrade pip`

update and install SSL certificate
(from certbot.eff.org)
$ sudo apt-get install software-properties-common $ sudo add-apt-repository ppa:certbot/certbot $ sudo apt-get update $ sudo apt-get install python-certbot-apache $ sudo certbot --apache

install line-bot-sdk and dependancies
$ pip install future $ pip install --upgrade requests $ pip install line-bot-sdk $ pip install --upgrade pyopenssl $ pip install flask

create line.py
(I've replaced the Channel Secret and Access Token)
Also i have no idea why i import OpenSSL

from flask import Flask, request, abort
from OpenSSL import SSL
from linebot import (
LineBotApi, WebhookHandler
)
from linebot.exceptions import (
InvalidSignatureError
)
from linebot.models import (
MessageEvent, TextMessage, TextSendMessage,
)
app = Flask(name)
line_bot_api = LineBotApi('CHANNEL_ACCESS_TOKEN')
handler = WebhookHandler('CHANNEL_SECRET')
@app.route("/callback", methods=['POST'])
def callback():
# get X-Line-Signature header value
signature = request.headers['X-Line-Signature']`
# get request body as text
body = request.get_data(as_text=True)
app.logger.info("Request body: " + body)
# handle webhook body
try:
handler.handle(body, signature)
except InvalidSignatureError:
abort(400)
return 'OK'
@handler.add(MessageEvent, message=TextMessage)
def handle_message(event):
line_bot_api.reply_message(
event.reply_token,
TextSendMessage(text=event.message.text))
context = ("/etc/letsencrypt/live/doodspav.com/fullchain.pem","/etc/letsencrypt/live/doodspav.com/privkey.pem")
if name == "main":
app.run(host="0.0.0.0",port=5000,ssl_context=context)

i've put the webhook url as doodspav.com:5000/
then run the script

sudo ufw allow 5000
python line.py

this is the printed response on my server whenever i send a message in a chat with the bot:
my_ip - - [24/Nov/2017 22:20:09] "POST / HTTP/1.1" 404 -

i'm honestly not sure what to do since it looks like other peoples code

I use the following simple code to test my line userid and push message.

from linebot import LineBotApi
from linebot.models import TextSendMessage

line_bot_api = LineBotApi('mytoken')
#push message to one user
profile = line_bot_api.get_profile('my line user id')

print(profile.display_name)
print(profile.user_id)
print(profile.picture_url)
print(profile.status_message)

line_bot_api.push_message('my line user id', TextSendMessage(text='Hello World!'))

I am pretty sure this id is correct because I use the other account in the same way can work.

However, this account will be an error message.(linebot.exceptions.LineBotApiError: <LineBotApiError [Not found]>) I also confirm that the settings are exactly the same.

Could you give me some advice?

Many thanks

Here's the dump. It's a Carousel. I'm pretty sure its within the max length of anything and I provided everything that's not optional. Thanks

{"altText": "Choose who to kill by typing '/ww act 3' by using the ids below\n8\t : Iklil Nur\n3\t : Rizqi Nur\n19\t : Juang\n7\t : A. M.

The error message was "A message (messages[0]) in the request body is invalid"

Hello,

Current Line API appears to require SSL for all webhooks (i.e. not just webhook URL verification). When I set up a working SSL context for Flask (see below), with a valid certificate chain from Let's Encrypt (root CA ISRG which is trusted by Line API), nothing appears to happen.

If I launch the examples (e.g. Flash echo bot) as is, I get HTTPS negotiation requests from Line API (Flask/Werkzeug complains as it's basically unexpected binary data, and can't handle it). However, if I set up a working HTTPS with a valid certificate (not self-signed), no webhook events are reported - I think Line API drops the connection since it is not satisfied with the HTTPS negotiation, but I'm yet to find a way for Werkzeug/whatever to debug-level report me all connection initiation attempts and how they look like:

        import ssl
        ctx = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
        ctx.load_cert_chain('pb1.mkj.lt/cert.pem', 'pb1.mkj.lt/privkey.pem')
        app.run(debug=options.debug, host="0.0.0.0", port=int(options.port), ssl_context=ctx)

This runs fine, but no webhooks are reported from the Line API. The webhook URL verification on Line Manager also fails without further explanation.

How should this be done, and is there a way to debug SSL issues / get info from Line API what fails in particular?

Thank you!
Kostas

P.S. I've also just tried with ssl.PROTOCOL_TLSv1_2 - same result.

Hi, I'm trying to reply the carousel template message. However the Line API keep telling me that my message is invalid. Here is the log:

But, the emoji(sticons) cannot show up.

It shows it's sysbol code, like (clov)(clov)(thinking of him)(Moon cool)

Hello I am trying to send an image data in my server to user. I have a static link to read the image. However we always update the image with different image with the same filename (overwrite). The original image file shows the right ones, but the preview always shows the first image (not updated version), but after I check in my server, both of the images have been updated.
How to force line to read again the preview image even the link is same?

Hi, I'm new to Line Messanger and Messaging API of line-bot-SDK-python.

I have tried to use the push_message command in Messaging API in order to send messages to my friends, but I can't send messages. How to get the , ID of the receiver, of my friends, groups, rooms? Where can I see those informations? What is ID of the receiver?

Thanks.

Today, we support the API of Business Accounts to create a bot (old BOT API): https://developers.line.me/businessconnect/development-bot-server and it works great. We refresh the tokens as it is specified in the documentation.

Now, we are integrating with Messaging API. Messaging API seems to not need to refresh any token unless you use the Social API, and I am not sure if we should still be using any of the Business Connect API endpoints.

Is the new Messaging API spec the standard for all accounts to create a bot?

How to send a message twice and pop up a new message bubble.

I've tried with "\ n" but it does not bring up a new message balloon.

Hello,

I'm new to working with Line, but I want to create a Bot that can read the Home messages (public profile) of a user and eventually can download those contents. I looked through the Messaging API and Social API but couldn't find anything related to the home profile. So my questions are can I handle the home page as a room/channel? Are there any related information that could help me with this project or is the idea entirely impossible?

I really appreciate any help you can provide.

Hello,

How do you reply with an text message and image message. I have tried using the ImageSendMessage class but i keep getting the same error. Just as a test i sent the url of a random 250x250 jpeg i found on the internet and that did not work.

Here is the traceback

It says i have two errors in the request body, but I don't really know what they are. In the API reference (https://devdocs.line.me/en/#common-specifications) they show an error message with the summary I am receiving above, with the details included. Is there a way to display the details of the error?

I use the codes in my project directly and I deploy my project onHeroku successfully.

The codes what I use is:

from flask import Flask, request, abort

from linebot import (
    LineBotApi, WebhookHandler
)
from linebot.exceptions import (
    InvalidSignatureError
)
from linebot.models import (
    MessageEvent, TextMessage, TextSendMessage,
)

app = Flask(__name__)

line_bot_api = LineBotApi('YOUR_CHANNEL_ACCESS_TOKEN')   #I put my TOKEN
handler = WebhookHandler('YOUR_CHANNEL_SECRET')


@app.route("/callback", methods=['POST'])
def callback():
    # get X-Line-Signature header value
    signature = request.headers['X-Line-Signature']

    # get request body as text
    body = request.get_data(as_text=True)
    app.logger.info("Request body: " + body)

    # handle webhook body
    try:
        handler.handle(body, signature)

    return 'OK'

        event.reply_token,
        TextSendMessage(text=event.message.text))


if __name__ == "__main__":
    app.run()

But the error appeared like that:

A http status of the response was '500 INTERNAL SERVER ERROR'.

I need your help. Thanks a lot.

I'm trying to send audio message via Line. The message was successfully sent from Line app. Then I get the binary via chunking. But it's weird that the binary output doesn't give the same voice as the original one. Any idea?

I'm not entirely sure if this is the API or line settings.

I have an issue where a bot keyword triggers the bot to send a photo to the group. If the user is using solely data, the photo either displays an incorrect photo or doesn't load at all. The photos are displayed perfectly for those who are using wifi.

Is there any insight on this? I'm sure it could be a whole host of reasons. One odd thing is that screenshots and other photos sent manually by users are being displayed fine under data. It's only images sent by the bot that are causing problems.

Thanks for the help.

New API was added.

I am using v1.0.2 with the kitchenSink example.
My JoinEvent handler is

@handler.add(JoinEvent)
def handle_join(event):
    wplog.logger.info("Got join event")
    line_bot_api.reply_message(
        event.reply_token,
        TextSendMessage(text='Joined this ' + event.source.type))

In a group chat between user ABC and bot, sequence of events:

1. User ABC send invite to user DEF
2. Bot sees Join Event and says "Joined this group"
3. 5 mins later, user DEF accepts invite and joins group
4. User DEF did not see Bot's msg "Joined this group"

In this correct? Why?

My expectation is:

1. User ABC send invite to user DEF
2. 5 mins later, user DEF accepts invite and joins group
3. Bot sees Join Event and says "Joined this group" (a welcome msg)
4. User DEF sees Bot's msg "Joined this group" (a welcome msg)

Thank you.

First of all, I'm sorry my English is very bad

My bot gets some user or group id is None
This error is not accidental
None values for users or groups are always None
This problem caused me to be unable to identify who my users are

Hi! I created a LINE Bot on AWS Lambda + API Gateway using Chalice.

https://github.com/c-bata/chalice-linebot

How would you like to add it on README as one example?
If you are ok, I'll send a Pull Request :)

I have tried absolutely everything to take a https png url, download it, convert it to the proper sizes, and return it as a jpg. Even taking a small 200px x 200px jpg image and trying to return it just results in the image url being displayed.

Want to make sure its not a bug in the ImageSendMessage function before I drive myself crazy.

I started from a fresh LAMP stack on Ubuntu 16.04, updated it and installed the latest version of pip.
Then I installed the line bot sdk, and all the requirements.
I made a new file, test.py and copy pasted the echobot script into it, changing the channel access token and secret. I also changed the app.run() to app.run(host="myip",port=443) since the webhook url i gave was https://myip:443/.
I ran this, and repeatedly got the same error code:

203.104.146.154 - - [22/Nov/2017 02:44:07] code 400, message Bad HTTP/0.9 request type ('\x16\x03\x03\x00\x82\x01\x00\x00~\x03\x03Z\x14\xe4w\xca\x12\xc4$\xae\xaa\xcb\x02\x1bF*\xa2S/\x11\xcd\\w\x0e~.\x03\xb2')

Not quite sure what to do tho, and any help would be appreciated.

Ive properly formatted the images according to the API specs and images display perfectly fine on mobile, tablet, and chrome app versions of line but no desktop client on any platform is able to view images.

Hi, I'm trying to run simple bot echo script. However the bot didn't received my message and it simply returning InvalidSignatureError. Here is the debug:

I suspect that it related to the signature check mechanism because I ran the script in local tunneled via ngrok.io. Is that really the problem?

I am trying out Messaging API and couldn't get push_message to work. Is there a specific type of Messaging API that support push_message. It seems I can only reply message.

Here is my error message.
{"message":"Access to this API is not available for your account"}

1. webhook url verify success
   but I'm not know that how I get userID like https://devdocs.line.me/en/#bot-api-get-profile

def callback():
    signature = request.headers['X-Line-Signature']

    body = request.get_data(as_text=True)
    app.logger.info("Request body: " + body)

def callback():
    signature = request.headers['X-Line-Signature']

    body = request.get_data(as_text=True)
    app.logger.info("Request body: " + body)

    if request.method=='GET':
        return 'ok get'
    elif request.method=='POST':
        return 'ok post'

    try:
        handler.handle(body, signature)
    except InvalidSignatureError:
        abort(400)

    return 'OK'

Bot is not running but webhook url can verify success.

I so confuse :(

Please help me. Thanks.

Line API Reference and python code is not consistent. Will be corrected in the next version?

With the datetime picker template action, you can provide an easy way for users to pick a date and time without having to type it in manually. The datetime picker action can be used in any type of template message and returns a postback event when the action is tapped.

Note: The datetime picker action is supported on LINE app versions iOS 7.9.0 and Android 7.12.0 and higher.

https://developers.line.me/news?ny=2017&nm=09

Best I can tell, there is no way to enable the 'tagging' feature through the API such that by adding @username the group member is alerted as being 'mentioned in a post'...
Is anyone aware of a way to do this through the API/this SDK?

Feel free to remove this question if it's totally off topic.
Thanks!

Situation:
I sent a image to the bot that I built,but the bot cannot recv my image.

I use the method as follows:

message_content = line_bot_api.get_message_content(message_id)
file_path = "C:\workplace\ngrok-line-bot\message\image\1.png"
with open(file_path,'wb') as fd:
	for chunk in message_content.iter_content():
		fd.write(chunk) 

Result:
the image cannot be sent and my bot also cannot recv.

I'm looking forward for your answer. Thank you :D

Hi @be-hase / @GuitarSucks

Currently, Join/Leave events are based on self. In other words, when Bot itself joins/leaves a group/room, it will receive the Join/Leave event.

The functionality my application is looking for, is Join/Leave events based on users. This means when a new user joins a group/room (in which Bot is present), Bot gets an event (preferably, this event includes userID of new user). This way, Bot can issue welcome message to the group/room, and give introductory instructions to new joins.

Will you consider this enhancement request? Thank you.

Hi
I created a rich menu, but I can't see anymore at line

rich_menu_to_create = RichMenu(
size=RichMenuBound(
width=2500,
height=1686
),
selected= False,
name="nice richmenu",
chatBarText="touch me",
areas=[
RichMenuArea(
RichMenuBound(
x=0,
y=0,
width=2500,
height=1686
),
URITemplateAction(
uri='line://nv/location'
)
)
]
)
rich_menu_id = line_bot_api.create_rich_menu(data=rich_menu_to_create)

Because I use line-bot-sdk-python, so I file issue here.

I find the Line Server is not provide expect callback for operation.

When I try to get "event.message.userId" message on JSON, I get as follow:

{
"message": {     
            "id": "7221963375040",
            "text": "TEST", 
            "type": "text"
            }, 
            "replyToken": "33f330692e5b493d8ba400652d62c14b",
            "source": {
                        "groupId": "C6f9ddd71af67bb47a3b00950aa51b59c", 
                        "type": "group", 
                        "userId": null
            }, 
            "timestamp": 1514533485276,
            "type": "message"
}

It missing some data under "userId" , so I cannot get "userId".

But it is not always happened.

Please let me know if you need any more detail.

Thank you.

I use the DatetimePickerTemplateAction part of unittest

https://github.com/line/line-bot-sdk-python/blob/master/tests/api/test_send_template_message.py

but below part is failed, time or date mode work fine.

DatetimePickerTemplateAction(
                                label="datetime picker datetime",
                                data="action=sell&itemid=2&mode=datetime",
                                mode="datetime",
                                initial="2013-04-01T10:00",
                                min="2011-06-23T00:00",
                                max="2017-09-08T23:59"
                            )

Hi,
I cannot change imageAspectRatio to sqaure for carousel. It looks like code in here is differece with code from pip install.

Thank you in advance.

I want to send a multicast message but can't figure out the syntax to do so.

I wanted to use WebHookParser but it's not being recognized when imported.

How could I do this using webhook handler?

Everytime I try:
'@handler.add(Source, message=TextMessage)
def handle_message(source):
line_bot_api.multicast(
event.source.userid,
TextSendMessage(text="hey")`

I know that's obviously wrong for both multicast and push messages. I'm new to this and could use help on the syntax. It would be helpful to create a code that prints specific pieces of parsed data I ask for.

I have tried a lot of variations similar to the kitchensink example here: https://github.com/line/line-bot-sdk-python/blob/master/examples/flask-kitchensink/app.py

I have another script that will trigger the multicast message. I just don't know how to gather up all of my users ids.

Any help would be appreciated, thank you.

https://devdocs.line.me/en/?python#content
In this document, the right side example python code

message_content = line_bot_api.get_content('<message_id>')

I think it should be

message_content = line_bot_api.get_message_content('<message_id>')
