Appium+python 使用 press_keycode 如何输入大写字母

​

背景：在做自动化测试项目时，需要在文本框中输入一串数字和字母组合的字符串（注：此页面为webview无法使用send_keys方法）

要使用send_keys方法首先要知道键盘字符对应的数值，这个可以在网上百度下，我把相关的对应关系已逻列到了下边，从以下对应

关系可知大写字母A和小字字母a对应的数值都是29， 在使用press_keycode(29) 时，文本框中输出的是小写的a,那如何输入大写的A呢?

分析： 查看press_keycode函数说明: def press_keycode(self, keycode, metastate=None, flags=None)

:Args:

- keycode - the keycode to be sent to the device   发送到设备的键值编码

- metastate - meta information about the keycode being sent   将被发送的元信息

- flags - the set of key event flags  设置的按键事件标记

我们通过键盘正常输入大写字母的操作方式 有三种 1,按下左侧shift键+字母   2. 按下右侧shift键+字母  3.按下caps_lock大小写锁定键输入字符

方法：我们以采用每一个方法为例输入大写字母A 

依次输入参数1输入字母A对应的数值 29  ，参数2 将元信息左shift 开关打开，参数3 模拟输入按下左shift键

(注：'META_SHIFT_LEFT_ON':64 'KEYCODE_SHIFT_LEFT':59  )

press_keycode(29,64,59)

 心得：由此方法可知，press_keycode 是可以模拟键盘的组如输入的如shifte+键盘，ctrl+键盘等等，需要与 META_键_ON 同时运用。
