selenium+python 去除启动的黑色cmd窗口方法


            其实 selenium启动窗口的时候就是 使用了subprocess.Popen 启动的驱动程序的,只要在启动的时候加上启动不显示窗口的参数即可。

下面魔改开始O(∩_∩)O哈哈~

修改代码 位于 D:\Python35\Lib\site-packages\selenium\webdriver\common\service.py 主要是 Service类的start函数





 def start(self):

  """

  Starts the Service.

  :Exceptions:

   - WebDriverException : Raised either when it can't start the service

   or when it can't connect to the service

  """

  try:

   cmd = [self.path]

   cmd.extend(self.command_line_args())

   if 'win32' in str(sys.platform).lower(): ### 这里判断是否是windows平台

    ### 在windows平台上就隐藏窗口

    startupinfo = subprocess.STARTUPINFO()

    startupinfo.dwFlags = subprocess.CREATE_NEW_CONSOLE | subprocess.STARTF_USESHOWWINDOW

    startupinfo.wShowWindow = subprocess.SW_HIDE

   else:

    startupinfo = None

   self.process = subprocess.Popen(cmd, env=self.env,

           close_fds=platform.system() != 'Windows',

           stdout=self.log_file, stderr=self.log_file,startupinfo=startupinfo) ### 启动驱动

   self.PID = self.process.pid ### 将cmd窗口的进程pid 保留 因为 窗口被隐藏了 所以在后续程序中必须考虑主控进程结束的时候必须结束掉 驱动cmd窗口进程

  except TypeError:

   raise

  except OSError as err:

   if err.errno == errno.ENOENT:

    raise WebDriverException(

     "'%s' executable needs to be in PATH. %s" % (

      os.path.basename(self.path), self.start_error_message)

    )

   elif err.errno == errno.EACCES:

    raise WebDriverException(

     "'%s' executable may have wrong permissions. %s" % (

      os.path.basename(self.path), self.start_error_message)

    )

   else:

    raise

  except Exception as e:

   raise WebDriverException(

    "The executable %s needs to be available in the path. %s\n%s" %

    (os.path.basename(self.path), self.start_error_message, str(e)))

  count = 0

  while True:

   self.assert_process_still_running()

   if self.is_connectable():

    break

   count += 1

   time.sleep(1)

   if count == 30:

    raise WebDriverException("Can not connect to the Service %s" % self.path)



注意 在前面先导入 sys包 

因为隐藏了驱动cmd窗口 所以 结束程序的时候 一定要做杀死驱动cmd窗口的动作哦 !O(∩_∩)O!!
