selenium+python 去除启动的黑色cmd窗口

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!!
