wechatircd IRC Telegram Gitter

wechatircd injects JavaScript (injector.js) to wx.qq.com, which uses WebSocket to communicate with an IRC server (wechatircd.py), thus enable IRC clients connected to the server to send and receive messages from WeChat, set topics, invite/delete members, ...

           IRC               WebSocket                 HTTPS
IRC client --- wechatircd.py --------- browser         ----- wx.qq.com
                                       injector.user.js
                                       injector.js

Installation

Arch Linux

  • yaourt -S wechatircd-git. It will generate a self-signed CA key/certificate pair /etc/wechatircd/ca.{cert,key}.pem and a key/certificate pair {cert,key}.pem (see below).
  • Import the CA certificate /etc/wechatircd/ca.cert.pem to the browser (see below).
  • systemctl start wechatircd, which runs /usr/bin/wechatircd --http-cert /etc/wechatircd/cert.pem --http-key /etc/wechatircd/key.pem --http-root /usr/share/wechatircd. You may want to customize /etc/systemd/system/wechatircd.service.

wechatircd.py (the server) will listen on 127.0.0.1:6667 (IRC) and 127.0.0.1:9000 (HTTPS + WebSocket over TLS).

If you run the server on another machine, it is recommended to set up IRC over TLS and an IRC connection password with a few more options: --irc-cert /path/to/irc.key --irc-key /path/to/irc.cert --irc-password yourpassword. As an alternative to the IRC connection password, you may specify --sasl-password yourpassword and authenticate with SASL PLAIN. You can reuse the HTTPS certificate+key. If you use WeeChat and find it difficult to set up a valid certificate (gnutls checks the hostname), type the following lines in WeeChat:

/set irc.server.wechat.ssl on
/set irc.server.wechat.ssl_verify off
/set irc.server.wechat.password yourpassword

Not Arch Linux

  • python >= 3.5
  • pip install -r requirements.txt
  • openssl req -x509 -newkey rsa:2048 -sha256 -nodes -keyout ca.key.pem -out ca.cert.pem -days 9999 -subj '/CN=127.0.0.1'
    openssl req -new -newkey rsa:2048 -sha256 -nodes -keyout key.pem -subj '/CN=127.0.0.1' |
      openssl x509 -req -out cert.pem -CAkey ca.key.pem -CA ca.cert.pem -set_serial 2 -days 9999 -extfile <(
        printf "subjectAltName = IP:127.0.0.1, DNS:localhost")
  • Import the CA certificate ca.cert.pem to the browser.
  • ./wechatircd.py --http-cert cert.pem --http-key key.pem

The IP address or the domain name used to serve injector.js and injector.user.js should match the subjectAlternativeName fields. Chrome has removed support for commonName matching in certificates since version 58. See https://developers.google.com/web/updates/2017/03/chrome-58-deprecations#remove_support_for_commonname_matching_in_certificates for detail.

Userscript and self-signed CA certificate

Chrome/Chromium

Firefox

  • Install extension Greasemonkey,install the userscript.
  • Visit https://127.0.0.1:9000/injector.js, Firefox will show "Your connection is not secure", Advanced->Add Exception->Confirm Security Exception

The server serves injector.js and WebSocket connections on 127.0.0.1:9000 by default, which can be overriden with --http-listen 0.0.0.0 --http-port 9000.

You can enable HTTPS in two ways:

  • --http-cert cert.pem --http-key key.pem to make wechatircd serve HTTPS
  • Omit --http-cert --http-key to make wechatircd serve HTTP, and use Nginx (with HTTPS enabled) as a reverse proxy. In this case, you need to pass Host: to wechatircd (proxy_set_header Host $http_host;) as it changes the WebSocket URL defined in injector.js according to Host: specified by the browser.

Usage

  • Run wechatircd.py
  • Visit https://wx.qq.com, the injected JavaScript will create a WebSocket connection to the server
  • Connect to 127.0.0.1:6667 in your IRC client

You will join +wechat channel automatically and find your contact list there. Some commands are available:

  • help
  • eval, eval a Python expression, such as: eval server.nick2special_user eval server.name2special_room
  • status, show contacts/channels
  • reload_contact __all__, reload all contact info in case of no such nick/channel in privmsg

The server can only be bound to one wx.qq.com account, however, you may have more than one IRC clients connected to the server.

IRC features

  • Standard IRC channels have names beginning with #.
  • WeChat groups have names beginning with &. The channel name is generated from the group title. SpecialChannel#update
  • Contacts have modes +v (voice, usually displayed with a prefix +). SpecialChannel#update_detail
  • Multi-line messages: !m line0\nline1
  • Multi-line messages: !html line0<br>line1
  • nick0: nick1: test will be converted to @GroupAlias0 @GroupAlias1 test, where GroupAlias0 is My Alias in Group/Name in profile/WeChat ID set by that user. It corresponds to On-screen names in the mobile application.
  • Reply to the message at 12:34:SS: @1234 !m multi\nline\nreply, which will be sent as 「Re GroupAlias: text」text
  • Reply to the message at 12:34:56: !m @123456 multi\nline\nreply
  • Reply to the penultimate message (your own messages are not counted) in this channel/chat: @2 reply
  • Paste detection. Lines will be hold for up to 0.1 seconds before sending, lines in this interval will be packed to a multiline message
  • --http-url https://127.0.0.1:9000 if you want to shorten media URLs to something like https://127.0.0.1:9000/media/0

!m, @3, nick: can be arranged in any order.

For WeeChat, its anti-flood mechanism will prevent two user messages sent to IRC server in the same time. Disable anti-flood to enable paste detection.

/set irc.server.wechat.anti_flood_prio_high 0

server-time extension from IRC version 3.1, 3.2. wechatircd.py includes the timestamp (obtained from JavaScript) in messages to tell IRC clients that the message happened at the given time. See http://ircv3.net/irc/. Seehttp://ircv3.net/software/clients.html for Client support of IRCv3.

Configuration for WeeChat:

/set irc.server_default.capabilities "account-notify,away-notify,cap-notify,multi-prefix,server-time,znc.in/server-time-iso,znc.in/self-message"

Supported IRC commands:

  • /cap, supported capabilities.
  • /dcc send $nick/$channel $filename, send image or file。This feature borrows the command /dcc send which is well supported in IRC clients. See https://en.wikipedia.org/wiki/Direct_Client-to-Client#DCC_SEND.
  • /invite $nick [$channel], invite a contact to the group.
  • /kick $nick, delete a group member. You must be the group leader to do this. Due to the defect of the Web client, you may not receive notifcations about the change of members.
  • /kill $nick [$reason], cause the connection of that client to be closed
  • /list, list groups.
  • /mode +m, no rejoin in --join new mode. /mode -m to revert.
  • /motd, view latest 5 commits of this repo
  • /names, update nicks in the channel.
  • /part [$channel], no longer receive messages from the channel. It just borrows the command /part and it will not leave the group.
  • /query $nick, open a chat window with $nick.
  • /squit $any, log out
  • /summon $nick $message,add a contact.
  • /topic topic, change the topic of a group. Because IRC does not support renaming of a channel, you will leave the channel with the old name and join a channel with the new name.
  • /who $channel, see the member list.

Display

  • MSGTYPE_TEXT,text, or invitation of voice/video call
  • MSGTYPE_IMG,image, displayed as [Image] $url

Changes in injector.js

  • Create a WebSocket connection to the server and retry on failures.
  • Hook contactFactory#{addContact,deleteContact} to watch changes to the contacts.
  • CtrlServer#onmessage, handle commands (text/file messages, invite someone to the group, ...) from the server.
  • CtrlServer#seenLocalID, prevent the client from receiving messages sent by itself.

FAQ

Motivation

If you cannot tolerant scanning QR codes with your phone everyday, see 无需每日扫码的IRC版微信和QQ:wechatircd、webqqircd.

Fetch data & control wx.qq.com

Some special accounts' UserName do not have the @ prefix: newsapp,fmessage,filehelper,weibo,qqmail,fmessage。Standard accounts' UserName start with @; Groups' UserName start with @@UserName are different among sessions. Uin looks like an unique identifier, but most of the time its value is 0. A group's OwnerUin is the owners's Uin,but most of the time Uin is 0.

My account

angular.element(document.body).scope().account

List of all contacts

angular.element($('#navContact')[0]).scope().allContacts

Delete a member from a group

var injector = angular.element(document).injector()
# 这里获取了chatroomFactory,还可用于获取其他factory、service、controller等
var chatroomFactory = injector.get('chatroomFactory')
# 设置其中的`room``userToRemove`
chatroomFactory.delMember(room.UserName, userToRemove.UserName)`

Send a message to the current chat

angular.element('pre:last').scope().editAreaCtn = "Hello,微信";
angular.element('pre:last').scope().sendTextMessage();

Headless browser on Linux

If you cannot tolerant scanning QR codes with your phone everyday, you can run the browser and wechatircd on a server.

  • Create a new browser user profile with chromium --user-data-dir=$HOME/.config/chromium-wechatircd, and do the aforementioned configuration (certificate for injector.js, Tampermonkey, injector.user.js), then close the browser.
  • Install xvfb (xorg-server-xvfb on Arch Linux)
  • xvfb-run -n 99 chromium --user-data-dir=$HOME/.config/chromium-wechatircd https://wx.qq.com
  • Wait a few seconds for the QR code. DISPLAY=:99 import -window root /tmp/a.jpg && $your_image_viewer /tmp/a.jpg, take a screenshot and scan the QR code with your mobile application.

You can interact with the browser using VNC:

  • x11vnc -localhost -display :99
  • In another terminal, vncviewer localhost

An alternative is x2go, see 无需每日扫码的IRC版微信和QQ:wechatircd、webqqircd.

How are nicks generated?

On the mobile application, users' On-screen Names are resolved in this order:

  • Set Remark and Tag if set
  • My Alias in Group(Group Alias) if set
  • Name in his/her profile
  • WeChat ID

Contact information is given in APIs batchgetcontact and webwxsync. The JSON serialization uses misleading field names.

WeChat friend in contactFactory#addContact:

  • .Alias: Name in his/her profile
  • .NickName: WeChat ID
  • .RemarkName: Set Remark and Tag

WeChat friend/non-contact in .MemberList:

  • .DisplayName: My Alias in Group
  • .NickName: Name in his/her profile or WeChat ID

JSON for one user may be returned repeatedly and all these fields may be empty. Users' nicks are generated by looking for the first non-empty value from these fields: .RemarkName, .NickName, .DisplayName. You may see xx now known as yy in your IRC client if a room contact shares multple rooms with you.

Known issues

Uncaught TypeError: angular.extend is not a function

You may see these messages in the DevTools console:

Uncaught TypeError: angular.extend is not a function
    at Object.setUserInfo (index_0c7087d.js:4)
    at index_0c7087d.js:2
    at c (vendor_2de5d3a.js:11)
    at vendor_2de5d3a.js:11
    at c.$eval (vendor_2de5d3a.js:11)
    at c.$digest (vendor_2de5d3a.js:11)
    at c.$apply (vendor_2de5d3a.js:11)
    at l (vendor_2de5d3a.js:11)
    at m (vendor_2de5d3a.js:11)
    at XMLHttpRequest.C.onreadystatechange (vendor_2de5d3a.js:11)
Uncaught TypeError: angular.forEach is not a function

injector.js should be executed after vendor_*.js and before index_*.js. However, TamperMonkey cannot finely control the execution time due to the limitation of Chrome.

Cannot send/receive new messages when the webpage disconnects from wx.qq.com

The WebSocket connection to wechatircd.py should be closed in this case, let users know they should reload the webpage.

Others

  • Log filenames may contain invalid filenames (:) on Windows
  • Stable channel names. This makes server-side log coherent and users will not be distracted by PART (Change name) JOIN messages. Channel names are generated from .NickName (Group Name) and Group Name may change. I do not know any persistent ID of an account/group because UserName changes in each new session.
