前言

     如果放弃太早，你永远都不知道自己会错过什么。

一、操作背景：

• 在做手机APP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，但无法使用sendkeys()方法的场景；
• 使用press_keycode()方法处理解决，但按键 大写字母A 和 小字字母a 对应的数值都是29，如何区分大小呢？

二、问题解决：

• press_keycode函数说明:
  def press_keycode(self, keycode, metastate=None, flags=None)
• 参数说明：
  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 ==》 press_keycode(29,64,59) 输入大写A
  2）按下右侧shift键+字母 ==》 press_keycode(29,128, 60) 输入大写A
  3）按下caps_lock大小写锁定键输入字符 press_keycode(29,115) 输入大写A

三、含义及资料：

• press_keycode(29,64,59)
  其中：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
