此文件使用终端命令获取wifi密码
netsh wlan show profiles
我之前使用 pyinstaller 创建了一些 .exe,它们工作得很好。
代码:
import subprocess
import time
import sys
import re
command_output = subprocess.run(["netsh", "wlan", "show", "profiles"], capture_output = True).stdout.decode()
profile_names = (re.findall("All User Profile : (.*)\r", command_output))
wifi_list = []
if len(profile_names) != 0:
for name in profile_names:
wifi_profile = {}
profile_info = subprocess.run(["netsh", "wlan", "show", "profile", name], capture_output = True).stdout.decode()
if re.search("Security key : Absent", profile_info):
continue
else:
wifi_profile["ssid"] = name
profile_info_pass = subprocess.run(["netsh", "wlan", "show", "profile", name, "key=clear"], capture_output = True).stdout.decode()
password = re.search("Key Content : (.*)\r", profile_info_pass)
if password == None:
wifi_profile["password"] = None
else:
wifi_profile["password"] = password[1]
wifi_list.append(wifi_profile)
for x in range(len(wifi_list)):
print(wifi_list[x])
time.sleep(5)
print("No more WiFi Profiles Found")
time.sleep(3)
sys.exit()
这是我运行 .exe 时遇到的错误:
Traceback (most recent call last):
File "GetWiFiPassWord.py", line 6, in <module>
File "subprocess.py", line 453, in run
File "subprocess.py", line 709, in __init__
File "subprocess.py", line 1006, in _get_handles
OSError: [WinError 6] The handle is invalid
这个错误显然是抛出的,因为:
subprocess.py 中的第 1117 行是:
p2cread = _winapi.GetStdHandle(_winapi.STD_INPUT_HANDLE)
服务进程没有与之关联的 STDIN(待定)。
可以通过提供文件或空设备作为
popen
的 stdin 参数来避免此问题。
在 Python 3.x 中,您可以简单地传递
。 例如stdin=subprocess.DEVNULL
subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=subprocess.DEVNULL)
在 Python 2.x 中,您需要将文件处理程序设置为 null,然后传递 那个打开:
devnull = open(os.devnull, 'wb') subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=devnull)
您的问题:
subprocess.run(["netsh", "wlan", "show", "profiles"], capture_output = True, stdin=subprocess.DEVNULL).stdout.decode()
我在使用 pyinstaller 时遇到了同样的问题:
PyInstaller: 4.5.1
Python: 3.9.6
Platform: Windows-10-10.0.19042-SP0
谢谢Behdad Abdollahi Moghadam。我通过将
stdin
和 stder
添加到 subprocess.check_output
解决了我的问题
subprocess.check_output("C:\Program Files (x86)\xxx.exe", stdin=subprocess.DEVNULL, stderr=subprocess.STDOUT)
