在安卓系统中编程连接WPA2企业级WiFi网络

Question

我刚刚尝试了一些连接WPA2企业网络的Android代码，但没有一个代码可以连接成功。我需要正确的代码来连接正确的网络。目前我使用了这个答案，但我需要一些澄清，因为这个答案是非常老的。这里我附上了一些有关连接的屏幕截图以便澄清。在这个屏幕截图中，您可以看到"身份"和"密码"两个字段。

  WifiConfiguration wifiConfiguration = new WifiConfiguration();
        wifiConfiguration.SSID = "\"" + networkSSID + "\"";
        wifiConfiguration.BSSID = Bssid;
        wifiConfiguration.hiddenSSID = true;
        wifiConfiguration.status = WifiConfiguration.Status.DISABLED;
        wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
        wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);
        wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
        wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
        wifiConfiguration.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
        wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
        wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
        wifiConfiguration.enterpriseConfig.setIdentity(identity);
        wifiConfiguration.enterpriseConfig.setPassword(password);

        wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);

       if (networkPasskey.matches("^[0-9a-fA-F]+$")) {
            wifiConfiguration.wepKeys[0] = networkPasskey;
        } else {
            wifiConfiguration.wepKeys[0] = "\"".concat(networkPasskey).concat("\"");
        }
        wifiConfiguration.wepTxKeyIndex = 0;

我在Wificonfiguration中找到了企业级功能，可以设置身份和密码。

    wifiConfiguration.enterpriseConfig.setIdentity(identity);
    wifiConfiguration.enterpriseConfig.setPassword(password);

但是这个有什么用处呢？我们已经有了身份和密码。

if (networkPasskey.matches("^[0-9a-fA-F]+$")) {
        wifiConfiguration.wepKeys[0] = networkPasskey;
    } else {
        wifiConfiguration.wepKeys[0] = "\"".concat(networkPasskey).concat("\"");
    }
    wifiConfiguration.wepTxKeyIndex = 0;

我正在使用BSSID，因为我的AP具有相同的ssid，所以我想通过使用BSSID连接正确的网络。

我通过这个链接得到帮助，已经解决了这个问题。

  WifiConfiguration config = new WifiConfiguration();
    config.SSID = "\"" + networkSSID + "\"";
    config.BSSID = Bssid;
    config.priority = 1;
 String networkIdentity = "";
         networkPasskey = "";
        config.status = WifiConfiguration.Status.ENABLED;
        WifiEnterpriseConfig enterpriseConfig = new WifiEnterpriseConfig();
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);
        enterpriseConfig.setIdentity(networkIdentity);
        enterpriseConfig.setPassword(networkPasskey);
        enterpriseConfig.setEapMethod(WifiEnterpriseConfig.Eap.PEAP);
        enterpriseConfig.setPhase2Method(WifiEnterpriseConfig.Phase2.MSCHAPV2);
        config.enterpriseConfig = enterpriseConfig;
   WifiManager myWifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    int id = myWifiManager.addNetwork(config);
    Log.d("addNetwork", "# addNetwork returned " + id);

    myWifiManager.enableNetwork(id, true);

但这种方法只能在安卓7.0版本以下使用，在安卓8.0中，他们限制了许多功能，我们无法手动添加wifi配置。

当您尝试配置WPA2企业级时，有三件事情是必须知道的：

1. 您必须了解EAP方法，它可以是任何东西，但通常使用PEAP

2.您必须了解Phase2方法，通常使用MSCHAPV2

3. 证书必须选择不验证。
