折腾：
【记录】尝试用Python操作PhantomJS+Selenium去模拟购物操作
期间，
selenium screenshot python
python – Webdriver Screenshot – Stack Overflow
Selenium take screenshot – Python Tutorial
然后用：
driver.save_screenshot(“befrugalHomepage.png”)
即可保存截图：
再去试试另外的：
Take screenshot of a webpage using Selenium & Python – IdiotInside.com
driver.get_screenshot_as_file
然后试了试：
driver.save_screenshot(“befrugalHomepage.png”)
# driver.get_screenshot_as_png(“befrugalHomepage1.png”)
driver.get_screenshot_as_file(“befrugalHomepage2.png”)
是可以生成图片的：
对应的三个函数，通过查看源码：
/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py
得知：
def get_screenshot_as_file(self, filename):
“””
Saves a screenshot of the current window to a PNG image file. Returns
False if there is any IOError, else returns True. Use full paths in
your filename.
:Args:
– filename: The full path you wish to save your screenshot to. This
should end with a `.png` extension.
:Usage:
driver.get_screenshot_as_file(‘/Screenshots/foo.png’)
“””
if not filename.lower().endswith(‘.png’):
warnings.warn(“name used for saved screenshot does not match file “
“type. It should end with a `.png` extension”, UserWarning)
png = self.get_screenshot_as_png()
try:
with open(filename, ‘wb’) as f:
f.write(png)
except IOError:
return False
finally:
del png
return True
def save_screenshot(self, filename):
“””
Saves a screenshot of the current window to a PNG image file. Returns
False if there is any IOError, else returns True. Use full paths in
your filename.
:Args:
– filename: The full path you wish to save your screenshot to. This
should end with a `.png` extension.
:Usage:
driver.save_screenshot(‘/Screenshots/foo.png’)
“””
return self.get_screenshot_as_file(filename)
def get_screenshot_as_png(self):
“””
Gets the screenshot of the current window as a binary data.
:Usage:
driver.get_screenshot_as_png()
“””
return base64.b64decode(self.get_screenshot_as_base64().encode(‘ascii’))
【总结】
selenium中截图的话，有两个函数都可以：
driver.save_screenshot(“screenshot_filename.png”)
内部就是调用get_screenshot_as_file实现的
driver.get_screenshot_as_file(“screenshot_filename.png”)
get_screenshot_as_file内部又是调用get_screenshot_as_png得到png截图的
