上期回顾：Airtest API精讲之wait(),exists()
以下基于
python3.8；airtestIDE1.2.11；airtest1.2.2；pocoui1.0.83
老规矩开场白，我们今天要讲的是Airtest框架的内容，不是Poco框架的，一般我们说Airtest，其实应该指的是Airtest Project，具体这些概念的关系是什么，可以看之前文章：Airtest Project——UI自动化利器介绍
今天我们讲一下Airtest中的keyevent()接口，它是在设备上执行keyevent按键事件，它包含2个参数：
-
keyname – 平台相关的按键名称
-
**kwargs – 平台相关的参数 kwargs
它支持Android、iOS、Windows三平台。
Android平台下的keyevent()
源码解析
先来看下源码(不想看源码的可以直接跳到后面的演示实例)：
# 文件位置：your_python_path/site-packages/airtest/core/android/android.py
def keyevent(self, keyname, **kwargs):
"""
Perform keyevent on the device
Args:
keyname: keyevent name
**kwargs: optional arguments
Returns:
None
"""
self.adb.keyevent(keyname)
可以看到，Android的keyevent()其实就是直接调用了adb的keyevent()。
我们再来看下adb的keyevent()：
# 文件位置：your_python_path/site-packages/airtest/core/android/adb.py
def keyevent(self, keyname):
"""
Perform `adb shell input keyevent` command on the device
Args:
keyname: key event name
Returns:
None
"""
self.shell(["input", "keyevent", keyname.upper()])
恩，是的，就是调用了adb的原始命令
adb shell input keyevent keycode
演示实例
# -*- encoding=utf8 -*-

from airtest.core.api import *
auto_setup(__file__)
# 点HOME键
keyevent("HOME")
keyevent("3") # 也可以用数值来代表
# 点BACK键
# 如果你的脚本要同时兼容Android和iOS，则不要使用，因为iOS不支持
keyevent("BACK")
keyevent("4") # 也可以用数值来代表
# 循环删除输入框内容
# Airtest没有清空输入框的方法，所以可以模拟真实的手工操作，就是不停的按删除键
for i in range(20):
keyevent("KEYCODE_DEL") # 或keyevent("67")

iOS平台下的keyevent()
源码解析
# 文件位置：your_python_path/site-packages/airtest/core/ios/ios.py
def keyevent(self, keyname, **kwargs):
"""
Perform keyevent on the device
Args:
keyname: home/volumeUp/volumeDown
**kwargs:
Returns:
"""
try:
keyname = KEY_EVENTS[keyname.lower()]
except KeyError:
raise ValueError("Invalid name: %s, should be one of ('home', 'volumeUp', 'volumeDown')" % keyname)
else:
self.press(keyname)
因为iOS的封闭性(很讨厌是不是)，所以只支持HOME、音量加、音量减3个键。
Windows平台下的keyevent()
源码解析
先来看下源码(不想看源码的可以直接跳到后面的演示实例)：
# 文件位置：your_python_path/site-packages/airtest/core/win/win.py
def keyevent(self, keyname, **kwargs):
"""
Perform a key event
References:
https://pywinauto.readthedocs.io/en/latest/code/pywinauto.keyboard.html
Args:
keyname: key event
**kwargs: optional arguments
Returns:
None
"""
self.keyboard.SendKeys(keyname)
可以看到Windows下是封装了第三方开源框架pywinauto中的方法。
