QT---Native Wifi functions 应用(WiFi有密码连接)

实现功能

无线网卡列表

无线热点扫面

无线连接（有密码，配置文件连接方式）

无线断开

重命名本地无线名（两种方式）

删除无线配置文件

开启和关闭无线网卡

Native Wifi 简介

是提供给软件开发者来开发windows 无线管理的一系列API。编程人员可以通过这些函数来进行相关的无线管理，当然我们还可以通过netsh终端命令来管理，这对于非编程人员就可以简单的实现，具体可以查阅相关资料去了解。

API如下：

WlanUIEditProfile

无线的连接相关知识

从windows的无线网络属性设置窗口来对比，在API编程中，同样有个配置文件来设置这些属性的，那就是profile文件，通过编写xml文件来设置相关属性。

WLAN_profile Schema Elements [xml配置文件编写格式]：

WLANProfile

Wireless Profile Samples[无线配置文件例程]

例如常见的路由器，安全类型为WPA2-PSK的xml配置文件如下（有密码）：

<?xml version="1.0" encoding="US-ASCII"?>
<WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">
<name>SampleWPA2PSK</name>
<SSIDConfig>
<SSID>
<name>SampleWPA2PSK</name>
</SSID>
</SSIDConfig>
<connectionType>ESS</connectionType>
<connectionMode>auto</connectionMode>
<autoSwitch>false</autoSwitch>
<MSM>
<security>
<authEncryption>
<authentication>WPA2PSK</authentication>
<encryption>AES</encryption>
<useOneX>false</useOneX>
</authEncryption>

<sharedKey>

<keyType>passPhrase</keyType>

<protected>false</protected>

<keyMaterial>  </keyMaterial>
</sharedKey>

</security>
</MSM>
</WLANProfile>

注：

【加密类型设置】

<encryption>AES</encryption>

    【安全类型设置】

<authentication>WPAPSK</authentication>

Value Description

open Open 802.11 authentication.

shared Shared 802.11 authentication.

WPAPSK WPA-Personal 802.11 authentication.

WPA2 WPA2-Enterprise 802.11 authentication.

WPA2PSK WPA2-Personal 802.11 authentication.

Value	Description
open	Open 802.11 authentication.
shared	Shared 802.11 authentication.
WPA	WPA-Enterprise 802.11 authentication.
WPAPSK	WPA-Personal 802.11 authentication.
