Python+itchat+PyQt5个人版微信(自动回复、防撤回、红包提醒等)

最近在学习python，无意中看到了itchat这个包，感觉很有意思，简单实现了一个LowB版微信，给女朋友捉弄朋友用。其实没有什么难度，做的很简陋，这里做下记录。

环境：

python3.6
PyQt5 5.11.2
itchat 1.3.10
wordcloud 1.5.0
matplotlib 2.1.2

GitHub地址

代码主要包括四个部分，itchat_thread.py负责itchat的相关处理，LogWindow.py是登陆窗口的代码，MainWindow.py 是主界面的代码，AutoReplyWechat.py相当于一个调度中心，包括main函数。

这部分代码功能很简单，就是获取itchat的登陆二维码

代码：

from PyQt5.QtWidgets import QDialog,QLabel,QPushButton,QVBoxLayout,QApplication
from PyQt5 import QtGui
import mathLogDialogWidth = 300
LogDialogHeight = 500class LogWindow(QDialog):def __init__(self):super(LogWindow, self).__init__()self.setStyle('qrc/dark.qss') # 设置样式self.initUI()def setStyle(self,_qssPath):with open(_qssPath,encoding='UTF-8') as file:str = file.read()qss = ''.join(str)self.setStyleSheet(qss)def initUI(self):self.mainButton = QPushButton(u'获取登录二维码',self)self.mainButton.setGeometry(int(math.ceil(LogDialogWidth / 2 - LogDialogWidth / 3 / 2)), int(math.ceil(LogDialogHeight / 10 * 8)),int(math.ceil(LogDialogWidth/3)), int(math.ceil(LogDialogHeight / 25)))self.labelQR = QLabel(self)self.labelQR.setFixedSize(280,280)self.labelQR.setAutoFillBackground(True)self.png = QtGui.QPixmap('qrc/welcome.png')self.labelQR.setPixmap(self.png)self.labelQR.setScaledContents(True)loginLayout = QVBoxLayout()loginLayout.addWidget(self.labelQR)loginLayout.addWidget(self.mainButton)self.setLayout(loginLayout)self.setWindowTitle(u'微信(by MisterGunner)')cx = (QApplication.desktop().width() - LogDialogWidth) / 2cy = (QApplication.desktop().height() - LogDialogHeight) / 2self.setGeometry(cx,cy,LogDialogWidth,LogDialogHeight)def setLabelPic(self,img):self.png = QtGui.QPixmap()self.png.loadFromData(img)self.labelQR.setPixmap(self.png)self.mainButton.setText('请扫码登录')

效果图：

itchat消息处理

这部分代码主要是微信消息的获取和后续处理，全部基于itchat来实现，后面别的有趣的功能也应该在这里增加。

ItchatThread继承QThread类，这里必须注意，itchat一定不能写在主线程里，会堵塞Qt部分，所以要单独开一个子线程，重写run函数。

run函数中，分别处理群和个人消息，关于itchat的api，具体可以参考官网说明。

个人消息部分：

调用get_head_img获取对方头像，并保存到本地。
如果是文本信息，聊天记录保存到本地文件log，然后存进一个list--msgHistory。上述list用来保存2min以内的聊天记录（2min以上无法撤回），用来实现防撤回功能。这里保存的信息主要包括创建时间，消息人昵称、备注、ID和内容。msgHistory因为只保存了最近2min的消息，所以要一直清理，否则会堆积太多内容。msgClear函数用来清理msgHistory，原理也很简单，当前时间跟最早的时间作差，大于120s即删除。
autoReply用来开启自动回复，通过Qt界面设置。自动回复调用了图灵机器人的API。
如果是NOTE类型的消息，检测其中的关键字，如果包含“红包”，发出一个信号，给Qt做相应处理；如果包含“撤回”字眼，则发送msgHistory的最近一条消息给自己的文件助手（这里只实现了发送撤回的最近一条消息）。
如果是图片消息，就下载到相应路径。
其他类型消息未做处理。

群消息处理类似。

最后调用auto_login，就可以获取二维码登录自己的微信了。这里注意，默认是调用电脑的看图软件打开二维码，或者可以在控制台利用字符显示。这里我想在qt界面显示，所以重写了qrCallBack，把图片数据发送给界面显示，loginCallBack负责通知界面登录状态。get_friends获取通讯录朋友信息，供界面使用。

主界面

这部分代码写的有点乱，其实没什么难度，主要是自己想实现的逻辑理清就ok了。

QTabWidget建了三个页，基本是模仿的微信PC端。

信息都是从itchatThread类获取的，然后就是几个类之间的互相通信。

聊天界面收到消息就会在左侧add朋友的消息，点击左侧的朋友，然后相应发给不同的人（未实现群聊天，只能收）。

通讯录基本跟原生微信一样，展示朋友，点击展示相应的information。没实现发送消息功能。

设置界面就是自动回复的开关了，checkbox是个人微信自动回复，下面是群消息自动回复，双击左侧选择，右侧是选定的，确认生效。

两个趣功能是在网上看到的，感觉很有意思，云词功能调用了wordcloud包，很好玩。我做了下简单改进在界面展示出来。
