用selenium+pil的image，截指定图，截取不到

不用截图，你直接在开发中工具拿到图片的地址连接就可以了

img = driver.find_element_by_xpath('')
location = img.location
size = img.size

top, bottom, left, right = location['y'], location['y'] + size['height'], location['x'], location['x'] + size['width']

screenShot = driver.get_screenshot_as_png()
screenShot = Image.open(BytesIO(screenShot))
img = screenShot.crop((int(left), int(top), int(right), int(bottom)))

img.save('filename.jpg')

以前写的截取滑动验证图片，不知道还能不能用
