使用ctypes函数在python中绑定键事件-bindingkeyeventinpythonusingctypesfunction

Linux input subsystem is composed of three parts: the driver layer, the input subsystem core layer and the event processing layer. and the keyboard or other input event is all describe by input_event.

Linux输入子系统由三部分组成:驱动层,输入子系统核心层和事件处理层。键盘或其他输入事件都由input_event描述。

use below code and type in your Terminal python filename.py | grep "keyboard"

使用下面的代码并在你的终端python filename.py中输入grep“键盘”

#!/usr/bin/env python
#coding: utf-8
import os

deviceFilePath = '/sys/class/input/'

def showDevice():
    os.chdir(deviceFilePath)
    for i in os.listdir(os.getcwd()):
        namePath = deviceFilePath + i + '/device/name'
        if os.path.isfile(namePath):
            print "Name: %s Device: %s" % (i, file(namePath).read())

if __name__ == '__main__':
    showDevice()

you should get Name: event1 Device: AT Translated Set 2 keyboard. then use

你应该得到名称:event1设备:AT Translated Set 2键盘。然后用

#!/usr/bin/env python
#coding: utf-8
from evdev import InputDevice
from select import select

def detectInputKey():
    dev = InputDevice('/dev/input/event1')

    while True:
        select([dev], [], [])
        for event in dev.read():
            print "code:%s value:%s" % (event.code, event.value)


if __name__ == '__main__':
    detectInputKey()

evdev is a package provides bindings to the generic input event interface in Linux. The evdev interface serves the purpose of passing events generated in the kernel directly to userspace through character devices that are typically located in /dev/input/.andselect is select.

evdev是一个包提供了对Linux中通用输入事件接口的绑定。 evdev接口的作用是通过通常位于/dev/input/中的字符设备将内核中生成的事件直接传递给用户空间。选择选择。
