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:\\')
