Python+selenium 获取浏览器窗口坐标、句柄的方法

1.0 获取浏览器窗口坐标

python目录可找到Webdriver.py 文件定义了get_window_rect()函数，可获取窗口的坐标和大小（长宽），但出现”Command not found”的情况。set_window_rect()函数也一样。

def get_window_rect(self):
 """
 Gets the x, y coordinates of the window as well as height and width of
 the current window.

 :Usage:
  driver.get_window_rect()
 """
 return self.execute(Command.GET_WINDOW_RECT)['value']

def set_window_rect(self, x=None, y=None, width=None, height=None):
 """
 Sets the x, y coordinates of the window as well as height and width of
 the current window.

 :Usage:
  driver.set_window_rect(x=10, y=10)
  driver.set_window_rect(width=100, height=200)
  driver.set_window_rect(x=10, y=10, width=100, height=200)
 """
 if (x is None and y is None) and (height is None and width is None):
  raise InvalidArgumentException("x and y or height and width need values")

 return self.execute(Command.SET_WINDOW_RECT,
  {"x": x, "y": y, "width": width, "height": height})['value']

然而Webdriver.py文件还定义了get_window_position()函数和get_window_size()函数，可以用这两个函数来分别获取窗口的坐标和大小，而不需要用到win32gui的方法。

def get_window_size(self, windowHandle='current'):
  """
  Gets the width and height of the current window.

  :Usage:
   driver.get_window_size()
  """
  command = Command.GET_WINDOW_SIZE
  if self.w3c:
   if windowHandle != 'current':
    warnings.warn("Only 'current' window is supported for W3C compatibile browsers.")
   size = self.get_window_rect()
  else:
   size = self.execute(command, {'windowHandle': windowHandle})

  if size.get('value', None) is not None:
   size = size['value']

  return {k: size[k] for k in ('width', 'height')}
def get_window_position(self, windowHandle='current'):
  """
  Gets the x,y position of the current window.

  :Usage:
   driver.get_window_position()
  """
  if self.w3c:
   if windowHandle != 'current':
    warnings.warn("Only 'current' window is supported for W3C compatibile browsers.")
   position = self.get_window_rect()
  else:
   position = self.execute(Command.GET_WINDOW_POSITION,
         {'windowHandle': windowHandle})['value']

  return {k: position[k] for k in ('x', 'y')}

2.0 获取窗口句柄

handle = driver.current_window_handle #获取当前窗口句柄
handles = driver.window_handles #获取所有窗口句柄

切换句柄可以使用

dr.switch_to.window(handle) #其中handle为获取到的窗口句柄

假设handles为获取到的所有窗口，则handles为一个list，可使用访问list的方法读取句柄。

dr.switch_to.windows(handles[0]) #切换到第一个窗口的句柄
dr.switch_to.windows(handles[-1]) #切换到最新窗口的句柄

以上这篇Python+selenium 获取浏览器窗口坐标、句柄的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持我们。
