废话不多说，先给大家看下python实现屏幕截图的代码，具体代码如下所述：

from selenium import webdriver import time def capture(url, save_fn="capture.png"): browser = webdriver.Firefox() # Get local session of firefox browser.set_window_size(1200, 900) browser.get(url) # Load page browser.execute_script(""" (function () { var y = 0; var step = 100; window.scroll(0, 0); function f() { if (y < document.body.scrollHeight) { y += step; window.scroll(0, y); setTimeout(f, 50); } else { window.scroll(0, 0); document.title += "scroll-done"; } }setTimeout(f, 1000); })(); """) for i in xrange(30): if "scroll-done" in browser.title: break time.sleep(1) browser.save_screenshot(save_fn) browser.close() if __name__ == "__main__": capture(http://www.jb51.net)

Pythony实现屏幕截屏的函数如下所述：

# -*- coding: cp936 -*- import time,Image import os, win32gui, win32ui, win32con, win32api def window_capture(dpath): ''''' 截屏函数,调用方法window_capture('d:') ,参数为指定保存的目录 返回图片文件名,文件名格式:日期.jpg 如:2009328224853.jpg ''' hwnd = 0 hwndDC = win32gui.GetWindowDC(hwnd) mfcDC=win32ui.CreateDCFromHandle(hwndDC) saveDC=mfcDC.CreateCompatibleDC() saveBitMap = win32ui.CreateBitmap() MoniterDev=win32api.EnumDisplayMonitors(None,None) w = MoniterDev[0][2][2] h = MoniterDev[0][2][3] #print w,h#图片大小 saveBitMap.CreateCompatibleBitmap(mfcDC, w, h) saveDC.SelectObject(saveBitMap) saveDC.BitBlt((0,0),(w, h) , mfcDC, (0,0), win32con.SRCCOPY) cc=time.gmtime() bmpname=str(cc[0])+str(cc[1])+str(cc[2])+str(cc[3]+8)+str(cc[4])+str(cc[5])+'.bmp' saveBitMap.SaveBitmapFile(saveDC, bmpname) Image.open(bmpname).save(bmpname[:-4]+".jpg") os.remove(bmpname) jpgname=bmpname[:-4]+'.jpg' djpgname=dpath+jpgname copy_command = "move %s %s" % (jpgname, djpgname) os.popen(copy_command) return bmpname[:-4]+'.jpg' #调用截屏函数 window_capture('d:')
