本程序实现定时向指定微信群发送指定消息的功能。
主要工具如下：
- python2.7编写;
itchat提供微信API接口，实现进行向群组发送消息;apscheduler提供定时器功能。
代码下载请到我的github仓库。
设计目的
最开始只是想能不能做一个程序，可以定时在周二，四，六晚上10点半提醒组员们上传日志，所以就开始了搜索。发现itchat这个超级好用的工具，在apscheduler的加持下最终编了这么一个程序。灵感总是来源于生活….
当然itchat的功能远不止是发送个群消息而已，它提供的微信API接口还可以做很多有意思的东西，比如最常见的机器人自动回复，还可以接入其他应用程序接口用微信号做一些小应用(如自动播放歌曲，返回天气信息等)。
依赖条件
Written in python2.7.12：
itchat1.3.10APScheduler3.5.1
功能描述
定义文件中的发送时间time，发送群组名roomName，发送消息context(消息中含中文字符时应该使用unicode编码)。
运行后会在time对应时间，往roomName对应群组，发送context对应的消息。
使用方法
修改
onTimeMsgSenderToChatroom.py文件中的time，roomName，context设置为自己需要的参数。具体参考如下：1
2
3roomName = u'两张王'
context=u'该消息由程序自动发送'
time = {'day_of_week':'*','hour':12,'minute':34,'second':26}运行
python onTimeMsgSenderToChatroom.py;- 扫描QR码，自动登陆成功后，等待信息自动发送即可。
示例
以下是用按照上述设置运行源代码向微信群发送的消息的截图。
