如何在 Android 中以编程方式创建和读取 WEP/EAP WiFi 配置
?
我在各种论坛和整个社区中看到许多人在这个问题上苦苦挣扎。我知道这不是那么直截了当(尤其是 EAP)要弄清楚,因为当我想实现同样的目标时,我也很挣扎。好吧,所有的代码分析和在互联网上搜索各种实现的辛勤工作都是用我完成的终于能够达到目的。所有功劳都归功于开源项目及其开发人员的数量。
我想与所有人分享这些知识,因为 SO encourages这个:“问和回答你自己的问题也很好,只要你假装你在危险中:用问题的形式表达出来。”
Part 1: Creating a WEP WiFi configuration programmatically.
Part 2: Read a WEP WiFi configuration programmatically.
最佳答案
第 1 部分:以编程方式创建 WEP WiFi 配置
这非常简单,WifiConfiguration公开接口(interface)以创建相同的接口(interface)。下面是示例代码:
void saveWepConfig()
{
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
wc.SSID = "\"SSID_NAME\""; //IMP! This should be in Quotes!!
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.DISABLED;
wc.priority = 40;
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
wc.wepKeys[0] = "\"aaabbb1234\""; //This is the WEP Password
wc.wepTxKeyIndex = 0;
WifiManager wifiManag = (WifiManager) this.getSystemService(WIFI_SERVICE);
boolean res1 = wifiManag.setWifiEnabled(true);
int res = wifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean es = wifi.saveConfiguration();
Log.d("WifiPreference", "saveConfiguration returned " + es );
boolean b = wifi.enableNetwork(res, true);
Log.d("WifiPreference", "enableNetwork returned " + b );
}
遵循 AndroidManifest.xml 中所需的权限
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE">
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE">
</uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE">
</uses-permission>
第 2 部分:以编程方式读取 WEP WiFi 配置
再次直截了当。下面是示例代码:
void readWepConfig()
{
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
List<WifiConfiguration> item = wifi.getConfiguredNetworks();
int i = item.size();
Log.d("WifiPreference", "NO OF CONFIG " + i );
Iterator<WifiConfiguration> iter = item.iterator();
WifiConfiguration config = item.get(0);
Log.d("WifiPreference", "SSID" + config.SSID);
Log.d("WifiPreference", "PASSWORD" + config.preSharedKey);
Log.d("WifiPreference", "ALLOWED ALGORITHMS");
Log.d("WifiPreference", "LEAP" + config.allowedAuthAlgorithms.get(AuthAlgorithm.LEAP));
Log.d("WifiPreference", "OPEN" + config.allowedAuthAlgorithms.get(AuthAlgorithm.OPEN));
Log.d("WifiPreference", "SHARED" + config.allowedAuthAlgorithms.get(AuthAlgorithm.SHARED));
Log.d("WifiPreference", "GROUP CIPHERS");
Log.d("WifiPreference", "CCMP" + config.allowedGroupCiphers.get(GroupCipher.CCMP));
Log.d("WifiPreference", "TKIP" + config.allowedGroupCiphers.get(GroupCipher.TKIP));
Log.d("WifiPreference", "WEP104" + config.allowedGroupCiphers.get(GroupCipher.WEP104));
Log.d("WifiPreference", "WEP40" + config.allowedGroupCiphers.get(GroupCipher.WEP40));
Log.d("WifiPreference", "KEYMGMT");
Log.d("WifiPreference", "IEEE8021X" + config.allowedKeyManagement.get(KeyMgmt.IEEE8021X));
Log.d("WifiPreference", "NONE" + config.allowedKeyManagement.get(KeyMgmt.NONE));
Log.d("WifiPreference", "WPA_EAP" + config.allowedKeyManagement.get(KeyMgmt.WPA_EAP));
Log.d("WifiPreference", "WPA_PSK" + config.allowedKeyManagement.get(KeyMgmt.WPA_PSK));
Log.d("WifiPreference", "PairWiseCipher");
Log.d("WifiPreference", "CCMP" + config.allowedPairwiseCiphers.get(PairwiseCipher.CCMP));
Log.d("WifiPreference", "NONE" + config.allowedPairwiseCiphers.get(PairwiseCipher.NONE));
Log.d("WifiPreference", "TKIP" + config.allowedPairwiseCiphers.get(PairwiseCipher.TKIP));
Log.d("WifiPreference", "Protocols");
Log.d("WifiPreference", "RSN" + config.allowedProtocols.get(Protocol.RSN));
Log.d("WifiPreference", "WPA" + config.allowedProtocols.get(Protocol.WPA));
Log.d("WifiPreference", "WEP Key Strings");
String[] wepKeys = config.wepKeys;
Log.d("WifiPreference", "WEP KEY 0" + wepKeys[0]);
Log.d("WifiPreference", "WEP KEY 1" + wepKeys[1]);
Log.d("WifiPreference", "WEP KEY 2" + wepKeys[2]);
Log.d("WifiPreference", "WEP KEY 3" + wepKeys[3]);
}
第 3 部分:以编程方式读取 EAP WiFi 配置
现在这很棘手。您可以在 WifiDialog.java 中找到通过 vanilla Android UI 保存 EAP WiFi 配置的代码。 .很简单我们可以在我们的应用程序中使用相同的代码,嗯,不!如果你碰巧尝试这个,你会得到错误提示找不到符号 eap
、phase
、client_cert
等等。稍微详细调查告诉我们EnterpriseField is private
在 WiFiConfiguration
类中,我们找不到的所有符号都是 EnterpriseField
类型。好吧,我们遇到了障碍,我们需要这些字段来读取/保存 EAP 配置,但我们没有对它们的编程访问权限!
Java 反射 API
救援好吧,我不是 Java 专家,所以我不会详细介绍反射 API,您可以在谷歌上搜索教程或获取更多信息 here .为了保持简短和甜蜜,Reflection API 允许您在运行时检查类、接口(interface)、字段和方法,而无需在编译时知道类、方法等的名称。还可以使用反射实例化新对象、调用方法和获取/设置字段值。重要的是,反射可以帮助您访问类中的私有(private)数据成员是我们需要的不是吗? :)
现在让我们检查一下代码示例,它展示了如何使用 Reflection Api 读取 EAP WiFi 配置。作为奖励,该 fragment 会将配置记录到文件中并将其保存在 SD 卡上....非常漂亮..eh ;) 一点点反射 Api 的概述,我相信掌握下面的代码很容易。
private static final String INT_PRIVATE_KEY = "private_key";
private static final String INT_PHASE2 = "phase2";
private static final String INT_PASSWORD = "password";
private static final String INT_IDENTITY = "identity";
private static final String INT_EAP = "eap";
private static final String INT_CLIENT_CERT = "client_cert";
private static final String INT_CA_CERT = "ca_cert";
private static final String INT_ANONYMOUS_IDENTITY = "anonymous_identity";
final String INT_ENTERPRISEFIELD_NAME = "android.net.wifi.WifiConfiguration$EnterpriseField";
这是在调用 readEapConfig()
函数之前在 SD 卡上创建日志文件的代码。
BufferedWriter out = null;
try
{
File root = Environment.getExternalStorageDirectory();
Toast toast = Toast.makeText(this, "SD CARD mounted and writable? " + root.canWrite(), 5000);
toast.show();
if (root.canWrite())
{
File gpxfile = new File(root, "ReadConfigLog.txt");
FileWriter gpxwriter = new FileWriter(gpxfile);
out = new BufferedWriter(gpxwriter);
out.write("Hello world");
//out.close();
}
} catch (IOException e)
{
Toast toast = Toast.makeText(this, "Problem reading SD CARD", 3000);
Toast toast2 = Toast.makeText(this, "Please take logs using Logcat", 5000);
Log.e("<<<<<<<<<<WifiPreference>>>>>>>>>>>>", "Could not write file " + e.getMessage());
}
现在是 readEapConfig()
函数本身:
void readEapConfig(BufferedWriter out)
{
/*Get the WifiService */
WifiManager wifi = (WifiManager)getSystemService(WIFI_SERVICE);
/*Get All WIfi configurations*/
List<WifiConfiguration> configList = wifi.getConfiguredNetworks();
/*Now we need to search appropriate configuration i.e. with name SSID_Name*/
for(int i = 0;i<configList.size();i++)
{
if(configList.get(i).SSID.contentEquals("\"SSID_NAME\""))
{
/*We found the appropriate config now read all config details*/
Iterator<WifiConfiguration> iter = configList.iterator();
WifiConfiguration config = configList.get(i);
/*I dont think these fields have anything to do with EAP config but still will
* print these to be on safe side*/
