wxauto是一个Python第三方库,用于自动化操作微信电脑客户端
通过wxauto,我们可以使用Python编写脚本,实现以下功能
使用wxauto需要先安装其库文件,可以使用pip命令进行安装
pip install wxauto
wxauto目前有WxParam、WxUtils、WeChat三个类:
from wxauto import *
# 获取当前微信客户端
wx = WeChat()
# 获取会话列表
wx.GetSessionList()
# 输出当前聊天窗口聊天消息
msgs = wx.GetAllMessage
for msg in msgs:
print('%s : %s'%(msg[0], msg[1]))
## 获取更多聊天记录
wx.LoadMoreMessage()
msgs = wx.GetAllMessage
for msg in msgs:
print('%s : %s'%(msg[0], msg[1]))
# 向某人发送消息(以`文件传输助手`为例)
msg = '你好~'
who = '文件传输助手'
wx.ChatWith(who) # 打开`文件传输助手`聊天窗口
wx.SendMsg(msg) # 向`文件传输助手`发送消息:你好~
## 发送换行消息(最近很多人问换行消息如何发送,新增说明一下)
msg = '''你好
这是第二行
这是第三行
这是第四行'''
who = '文件传输助手'
WxUtils.SetClipboard(msg) # 将内容复制到剪贴板,类似于Ctrl + C
wx.ChatWith(who) # 打开`文件传输助手`聊天窗口
wx.SendClipboard() # 发送剪贴板的内容,类似于Ctrl + V
# 向某人发送文件(以`文件传输助手`为例,发送三个不同类型文件)
file1 = 'D:/test/wxauto.py'
file2 = 'D:/test/pic.png'
file3 = 'D:/test/files.rar'
who = '文件传输助手'
wx.ChatWith(who) # 打开`文件传输助手`聊天窗口
wx.SendFiles(file1, file2, file3) # 向`文件传输助手`发送上述三个文件
# 注:为保证发送文件稳定性,首次发送文件可能花费时间较长,后续调用会缩短发送时间
# 向某人发送程序截图(以`文件传输助手`为例,发送微信截图)
name = '微信'
classname = 'WeChatMainWndForPC'
wx.ChatWith(who) # 打开`文件传输助手`聊天窗口
wx.SendScreenshot(name, classname) # 发送微信窗口的截图给文件传输助手
注:为保证发送文件稳定性,首次发送文件可能花费时间较长,后续调用会缩短发送时间
由于部分版本的微信可能由于UI界面不同从而无法使用,截至2022-06-10
最新版本可用
因此在代码运行的时候,会发现图片无法发送、消息无法发送
的报错情况 LookupError: Find Control Timeout(10s): {Name: '输入', ControlType: EditControl}
,这是因为pip 下载的wxauto第三方库无法匹配微信客户端3.7的版本
。
如果有遇到,可以通过Github的方式下载源码,直接修改源码
wxauto库信息:
Author: tikic@qq.com
Source: https://github.com/cluic/wxauto
Version: 3.3.5.3
微信最新版本需要重新适配,需修改 wxauto.py 代码
1.在 wxauto.py 的文件中找到 WeChat 的类,并添加下述方法
def ChangeWindow(self, window_title):
self.EditMsg = self.UiaAPI.EditControl(Name=f'{window_title}')
2.之后在 ChatWith 方法中加入如下代码
def ChatWith(self, who, RollTimes=None):
'''
打开某个聊天框
who : 要打开的聊天框好友名,str; * 最好完整匹配,不完全匹配只会选取搜索框第一个
RollTimes : 默认向下滚动多少次,再进行搜索
'''
self.UiaAPI.SwitchToThisWindow()
self.ChangeWindow(who) # [2] 加入如下方法,在每次更改聊天对象时调用 ChangeWindow 方法
... ...
