webqqircd

webqqircd类似于bitlbee，在WebQQ(SmartQQ)和IRC间建起桥梁，可以使用IRC客户端收发消息。大部分代码来自wechatircd，为适配QQ做了一些修改。

           IRC              WebSocket                 HTTPS
IRC client --- webqqircd.py --------- browser        ----- wx.qq.com
                                      modified mq.js

原理

修改WebQQ(http://w.qq.com用的JS，通过WebSocket把信息发送到服务端，服务端兼做IRC服务端，把IRC客户端的命令通过WebSocket传送到网页版JS执行。未实现IRC客户端，因此无法把QQ群/讨论组的消息转发到另一个IRC服务器(打通两个群的bot)。

WebQQ局限

WebQQ不支持发送图片，也无法获悉别人发送了图片
消息发送后不知道成功与否，mq.model.chat中sendMsg(h)的onSuccess为空函数
无法获知群/讨论组信息变化(如成员变化等)mq.model.chat中addGroup(x)只判断群/讨论组存在与否，不判断信息变化
看不到WebQQ会话内新加入的群/讨论组友的消息
没有办法区分<和<等

安装

需要Python 3.5或以上，支持async/await语法 pip install -r requirements.txt安装依赖

Arch Linux

yaourt -S webqqircd-git。会在/etc/webqqircd/下生成自签名证书。
把/etc/webqqircd/cert.pem导入到浏览器(见下文)
systemctl start webqqircd会运行/usr/bin/webqqircd --http-cert /etc/webqqircd/cert.pem --http-key /etc/webqqircd/key.pem --http-root /usr/share/webqqircd

IRC服务器默认监听127.0.0.1:6668 (IRC)和127.0.0.1:9002 (HTTPS + WebSocket over TLS)。

如果你在非本机运行，建议配置IRC over TLS，设置IRC connection password：/usr/bin/webqqircd --http-cert /etc/webqqircd/cert.pem --http-key /etc/webqqircd/key.pem --http-root /usr/share/webqqircd --irc-cert /path/to/irc.key --irc-key /path/to/irc.cert --irc-password yourpassword

可以把HTTPS私钥证书用作IRC over TLS私钥证书。使用WeeChat的话，如果觉得让WeeChat信任证书比较麻烦(gnutls会检查hostname)，可以用：

set irc.server.qq.ssl on`
set irc.server.qq.ssl_verify off
set irc.server.qq.password yourpassword`

其他发行版

openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -out cert.pem -subj '/CN=127.0.0.1' -days 9999创建密钥与证书。
把cert.pem导入浏览器，见下文
./webqqircd.py --http-cert cert.pem --http-key key.pem

浏览器设置

Chrome/Chromium

访问chrome://settings/certificates，导入cert.pem，在Authorities标签页选择该证书，Edit->Trust this certificate for identifying websites.
安装Switcheroo Redirector扩展，把http://pub.idqqimg.com/smartqq/js/mq.js?t=20161220重定向至https://127.0.0.1:9002/mq.js。

Firefox

安装Redirector扩展，重定向js，设置 Applies to: Main window (address bar), Scripts。
访问重定向后的js URL，报告Your connection is not secure，Advanced->Add Exception->Confirm Security Exception

使用

运行webqqircd.py
访问http://w.qq.com，修改后mq.js会向服务器发起WebSocket连接
IRC客户端连接127.1:6668(weechat的话使用/server add qq 127.1/6668)，会自动加入+qq channel

在+qq发信并不会群发，只是为了方便查看有哪些朋友。

在+qq channel可以执行一些命令：

help，帮助
status [pattern]，已获取的QQ朋友、群/讨论组列表，支持 pattern 参数用来筛选满足 pattern 的结果，目前仅支持子串查询。如要查询所有群/讨论组，由于群/讨论组由 & 开头，所以可以执行 status &。
eval $password $expr: 如果运行时带上了--password $password选项，这里可以eval，方便调试，比如eval $password client.webqq_users

服务器选项

Join mode. There are three modes, the default is --join auto: join the channel upon receiving the first message. The other two are --join all: join all the channels; --join manual: no automatic join.
Groups that should not join automatically. This feature supplements join mode.
- --ignore 'fo[o]' bar, do not auto join chatrooms whose channel name(generated from DisplayName) matches regex fo[o] or bar
- --ignore-display-name 'fo[o]' bar, do not auto join chatrooms whose DisplayName matches regex fo[o] or bar
HTTP/WebSocket related options
- --http-cert cert.pem, TLS certificate for HTTPS/WebSocket. You may concatenate certificate+key, specify a single PEM file and omit --http-key. Use HTTP if neither --http-cert nor --http-key is specified.
- --http-key key.pem, TLS key for HTTPS/WebSocket.
- --http-listen 127.1 ::1, change HTTPS/WebSocket listen address to 127.1 and ::1, overriding --listen.
- --http-port 9000, change HTTPS/WebSocket listen port to 9000.
- --http-root ., the root directory to serve injector.js.
-l 127.0.0.1, change IRC/HTTP/WebSocket listen address to 127.0.0.1.
IRC related options
- --irc-cert cert.pem, TLS certificate for IRC over TLS. You may concatenate certificate+key, specify a single PEM file and omit --irc-key. Use plain IRC if neither --irc-cert nor --irc-key is specified.
- --irc-key key.pem, TLS key for IRC over TLS.
- --irc-listen 127.1 ::1, change IRC listen address to 127.1 and ::1, overriding --listen.
- --irc-password pass, set the connection password to pass.
- --irc-port 6667, IRC server listen port.
Server side log
- --logger-ignore '&test0' '&test1', list of ignored regex, do not log contacts/groups whose names match
- --logger-mask '/tmp/webqq/$channel/%Y-%m-%d.log', format of log filenames
- --logger-time-format %H:%M, time format of server side log

IRC命令

标准IRC channel名以#开头
QQ群/讨论组名以&开头。SpecialChannel#update
联系人带有mode +v (voice, 通常显示为前缀+)。SpecialChannel#update_detail

server-time extension from IRC version 3.1, 3.2. webqqircd.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.
/list, list groups.
/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.
/who $channel, see the member list.

Multi-line messages:

!m line0\nline1

JS改动

原始文件mq.js在Chrome DevTools里格式化后得到orig/mq.pretty.js，可以用diff -u orig/mq.pretty.js mq.js查看改动。

修改的地方都有//@标注，结合diff，方便WebQQ更新后重新应用这些修改。增加的代码中大多数地方都用try catch保护，出错则consoleerr(ex.stack)。

目前的改动如下：

`mq.js`开头

创建到服务端的WebSocket连接，若onerror则自动重连。监听onmessage，收到的消息为服务端发来的控制命令：send_text_message等。

定期把通讯录发送到服务端

获取所有联系人(朋友、订阅号、群/讨论组)，deliveredContact记录投递到服务端的联系人，deliveredContact记录同处一群/讨论组的非直接联系人。

每隔一段时间把未投递过的联系人发送到服务端。

收到QQ服务器消息`messageProcess`

原有代码会更新未读标记数及声音提醒，现在改为若成功发送到服务端则不再提醒，以免浏览器的这个标签页造成干扰。

Python服务端代码

当前只有一个文件webqqircd.py，从miniircd抄了很多代码，后来自己又搬了好多RFC上的用不到的东西……
