前言

接到了一个需求：现微信有8000+好友，需要给所有好友发送一则一样的消息。网上搜索一番后，发现uiautomation 可以解决该需求，遂有此文。这是第二篇，群发消息给微信好友

代码在文章末尾，自取~

知识点📖

代码实现

完整代码在文末，这里只演示使用效果~

本文示例的文件夹如下：

• 值得注意的是，如果发送的文件与Python处理同级目录，则无需填写绝对路径

下面用Python代码去将这些文件发送给指定的微信好友

发送文本

wx = WxOperation()
# 发送文本
wx.send_msg(
    '文件传输助手',
    msgs=['hello', 'world']
)

代码运行效果如下动图所示~

发送文件

wx = WxOperation()
# 发送文件
wx.send_msg(
    '文件传输助手',
    file_paths=['demo.bat', 'demo.png']
)

代码运行效果如下动图所示~

发送文本+文件

wx.send_msg(
    '文件传输助手',
    msgs=['hello', 'world'],
    file_paths=['demo.bat', 'demo.png']
)

代码运行效果如下动图所示~

批量发送文本+文件

wx = WxOperation()
# 群发
wx.send_msg(
    *['文件传输助手', '靓仔'],	# 
    msgs=['hello', 'world'],
    file_paths=['demo.bat', 'demo.png']
)

代码运行效果如下动图所示~
