在CENTOS上编译pidgin-lwqq,配置qq机器人

首先,yum安装各种需要的东西,比如pidgin,以及后面需要用到的依赖包,其中dbus是用来通信的

yum install pidgin-devel finch screen dbus dbus-devel dbus-x11 libev-devel zlib-devel glibc-devel cmake sqlite-devel libcurl-devel

其次,通过git clone pidgin-lwqq来进行编译,详细的见https://github.com/xiehuc/pidgin-lwqq,不过这里需要注意两点:

  1. 切换到dev分支,不然没法编译,master分支需要依赖一个mozjs的东西,centos上可以搞,但是相当麻烦
  2. 因为是在一个没有图形界面的系统(比如VPS)上编译,需要将验证码输出到一个web可访问的路径去,否则登录不了。修改方法大致如下:
diff --git a/lib/login.c b/lib/login.c
index 8fe25c0..a1ae11b 100644
--- a/lib/login.c
+++ b/lib/login.c

然后,编译好之后,就可以先试试登录了,直接敲入finch试试,目测就能看到登录界面了

选择webqq进行登录,使用快捷键还是很方便的,不会使用可以man一下

下面就是机器人部分了,pidgin支持dbus通信,于是我们可以用利用dbus的接口来监听qq的消息,并作出回应,抑或是主动发出消息。要使用dbus,那么finch需要运行在screen下,这也是前面安装screen的原因,简单点,在命令行里敲入

dbus-launch screen

即可启动dbus,并进入screen,然后在screen下运行finch即可。友情提示,某些terminal里,screen下的finch排版混乱,至今没找到解决方案。另外,screen的使用方法可以man一下,你的通信脚本也必须运行在screen里。

dbus通信可以用多个语言实现,c、python、php等等都可以,个人熟悉php,因此使用php进行编写机器人脚本。首先安装php扩展dbus:

pecl install dbus-0.1.1

装完记得在php.ini里加入dbus的配置

[dbus]
extension=dbus.so

网上能找到很多示例代码,比如PHP官网就有很多example:传送门在此

下面贴个简单自动重复消息的机器人代码

  1. 蛀虫 蛀虫

    按照你的方法是装好了,但是dbus与php通信貌似一直没成功

  2. 路过 技术文章 看不懂呃

  3. wow, 好腻害,已经装好了

    1. 随流逝去 随流逝去

      是需要怎么做呢,安装完pidgin,下面的git clone pidgin-lwqq不能直接出来安装
