Originally, press key method was used for keyboard operation in robotframework, but this method needs to write locator of the operated object, which is not very convenient. Now, a method for writing keyboard operation in win32api library has been found (note: the operation interface of this method must be at the top level). First, python library of win32api needs to be installed, and commands are used:
pip install pywin32
The specific implementation code is as follows:
import win32api
import win32con
class MyLibrary(object):
def keybd_event(self,VK_CODE): #VK_CODE Encode the keyboard
# @Keyboard
# input
VK_CODE = int(VK_CODE)
print ":::VK_CODE:", VK_CODE
win32api.keybd_event(VK_CODE, 0, 0, 0)
win32api.keybd_event(VK_CODE, 0, win32con.KEYEVENTF_KEYUP, 0)
print ":::press", str(VK_CODE), "successfully!"
time.sleep(2)
if __name__ == '__main__':
keybd_event(40) # Keyboard press direction down key
