win11、win10使用python代码打开和关闭wifi热点的正确方法

问题一

win10、win11，可以在任务栏的WIFI图标启动移动热点，但是无法设置SSID和密码。在网上搜索好久，无解。
万能的网络解决不了，只能自己动手解决了。

问题二

我当前的WiFi驱动程序不支持承载网络，如果我输入netsh wlan show drivers，显示“支持的承载网络 : 否”。更换驱动程序后还是不支持，无法解决，也就是说无法使用如下命令启动移动热点：

netsh wlan set hostednetwork mode=allow ssid=XXXXXXXXX key=YYYYYYYYYYY
netsh wlan start hostednetwork

执行“netsh wlan start hostednetwork”这条命令会提示“无法启动承载网络”。

通过在网络上查询，得知Windows 10已经抛弃了承载网络，现在的移动热点基于WiFi Direct技术。
通过cmd命令行是无法启动新的基于WiFi Direct技术的移动热点的。

解决方案

wifi.ps1：

[Windows.System.UserProfile.LockScreen,Windows.System.UserProfile,ContentType=WindowsRuntime] | Out-Null
Add-Type -AssemblyName System.Runtime.WindowsRuntime
$asTaskGeneric = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and $_.GetParameters()[0].ParameterType.Name -eq 'IAsyncOperation`1' })[0]
 
Function Await($WinRtTask, $ResultType) {
    $asTask = $asTaskGeneric.MakeGenericMethod($ResultType)
    $netTask = $asTask.Invoke($null, @($WinRtTask))
    $netTask.Wait(-1) | Out-Null
    $netTask.Result
}
 
# 这个函数本次的功能中没有使用，可以删除
Function AwaitAction($WinRtAction) {
    $asTask = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and !$_.IsGenericMethod })[0]
    $netTask = $asTask.Invoke($null, @($WinRtAction))
    $netTask.Wait(-1) | Out-Null
}
 
$connectionProfile = [Windows.Networking.Connectivity.NetworkInformation,Windows.Networking.Connectivity,ContentType=WindowsRuntime]::GetInternetConnectionProfile()
$tetheringManager = [Windows.Networking.NetworkOperators.NetworkOperatorTetheringManager,Windows.Networking.NetworkOperators,ContentType=WindowsRuntime]::CreateFromConnectionProfile($connectionProfile)
 
 
# 检查 Windows 10 移动热点的状态
$tetheringManager.TetheringOperationalState
 
# 如果移动热点是开启状态，则关闭移动热点
if ($tetheringManager.TetheringOperationalState -eq 1){
    # 关闭移动热点
    Await ($tetheringManager.StopTetheringAsync()) ([Windows.Networking.NetworkOperators.NetworkOperatorTetheringOperationResult])
}
# 如果移动热点是关闭状态，则设置热点名称、热点的密码，然后开启移动热点
else{
 
    # 启动前先为移动热点设置SSID、密码
    $accessPoint = $tetheringManager.GetCurrentAccessPointConfiguration()
    # 为移动热点设置SSID
    $accessPoint.Ssid = "wifi_stzz"
    # 为移动热点设置密码
    $accessPoint.Passphrase = "12345678"
    $tetheringManager.ConfigureAccessPointAsync($accessPoint)
 
    # 启动/开启移动热点
    Await ($tetheringManager.StartTetheringAsync()) ([Windows.Networking.NetworkOperators.NetworkOperatorTetheringOperationResult])
}

由于Windows10、Windows111系统默认的策略是禁止直接运行ps1脚本文件的,所以需要先修改一下系统策略

使用管理员权限打开powershell

set-executionpolicy remotesigned

python代码：

import os
from glob import glob
import subprocess as sp


class PowerShell:
    # from scapy
    def __init__(self, coding, ):
        cmd = [self._where('PowerShell.exe'),
               "-NoLogo", "-NonInteractive",  # Do not print headers
               "-Command", "-"]  # Listen commands from stdin
        startupinfo = sp.STARTUPINFO()
        startupinfo.dwFlags |= sp.STARTF_USESHOWWINDOW
        self.popen = sp.Popen(cmd, stdout=sp.PIPE, stdin=sp.PIPE, stderr=sp.STDOUT, startupinfo=startupinfo)
        self.coding = coding

    def __enter__(self):
        return self

    def __exit__(self, a, b, c):
        self.popen.kill()

    def run(self, cmd, timeout=15):
        b_cmd = cmd.encode(encoding=self.coding)
        try:
            b_outs, errs = self.popen.communicate(b_cmd, timeout=timeout)
        except sp.TimeoutExpired:
            self.popen.kill()
            b_outs, errs = self.popen.communicate()
        outs = b_outs.decode(encoding=self.coding)
        return outs, errs

    @staticmethod
    def _where(filename, dirs=None, env="PATH"):
        """Find file in current dir, in deep_lookup cache or in system path"""
        if dirs is None:
            dirs = []
        if not isinstance(dirs, list):
            dirs = [dirs]
        if glob(filename):
            return filename
        paths = [os.curdir] + os.environ[env].split(os.path.pathsep) + dirs
        try:
            return next(os.path.normpath(match)
                        for path in paths
                        for match in glob(os.path.join(path, filename))
                        if match)
        except (StopIteration, RuntimeError):
            raise IOError("File not found: %s" % filename)


if __name__ == '__main__':
    # Example:
    with PowerShell('GBK') as ps:
        outs, errs = ps.run('set-executionpolicy remotesigned')
    print('error:', os.linesep, errs)
    print('output:', os.linesep, outs)

    with PowerShell('GBK') as ps:
        outs, errs = ps.run('./wifi.ps1')
    print('error:', os.linesep, errs)
    print('output:', os.linesep, outs)

而对于win7：

def start_wifi_hotspot(ssid, password):
    # 设置热点配置命令
    set_config_cmd = 'netsh wlan set hostednetwork mode=allow ssid={} key={}'.format(ssid, password)
    subprocess.call(set_config_cmd, shell=True)

    # 启动热点命令
    start_hotspot_cmd = 'netsh wlan start hostednetwork'
    subprocess.call(start_hotspot_cmd, shell=True)

# 在这里设置热点的名称和密码
ssid = "XXXXXXXXX"
password = "YYYYYYYYYYYY"

start_wifi_hotspot(ssid, password)
