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!!
