本文介绍了如何从Android的WifiConfiguration项获得无线网络的安全性(无,WEP,WPA,WPA2)?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我需要从 WifiConfiguration 项安全类型。这可能吗?

I need to get security type from WifiConfiguration entry. Is it possible?

String getSecurityType(WifiConfiguration conf) {
}

返回值无,WEP,WPA,WPA2

对于那些谁认为这是一个重复的问题:我想从 WiFiConfiguration 对象的信息,而不是从 ScanResult 对象。这是不一样的!

For those who think it's a duplicate question: I want to get information from WiFiConfiguration object and not from ScanResult object. It's not the same!

推荐答案

我能做到这一点,简单地说:

I can do it, simply:

import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiConfiguration.AuthAlgorithm;
import android.net.wifi.WifiConfiguration.KeyMgmt;

public static final int SECURITY_NONE = 0;
public static final int SECURITY_WEP = 1;
public static final int SECURITY_PSK = 2;
public static final int SECURITY_EAP = 3;

public static int getSecurity(WifiConfiguration config) {
    if (config.allowedKeyManagement.get(KeyMgmt.WPA_PSK)) 
        return SECURITY_PSK;

    if (config.allowedKeyManagement.get(KeyMgmt.WPA_EAP) || config.allowedKeyManagement.get(KeyMgmt.IEEE8021X)) 
        return SECURITY_EAP;

    return (config.wepKeys[0] != null) ? SECURITY_WEP : SECURITY_NONE;
}

所以...

so...

public static String getSecurityType(WifiConfiguration config) {
    switch (getSecurity(config)) {
        case SECURITY_WEP:
            return "WEP";
        case SECURITY_PSK:
            if (wifiConfiguration.allowedProtocols.get(WifiConfiguration.Protocol.RSN))
                return "WPA2";
            else
                return "WPA";
        default:
            return "NONE";
    }
}
