Android与CaptiveNetwork API（iOS）等效吗？

Question

我希望注册用户连接到WiFi网络并进行无缝身份验证。 当用户正在运行应用程序并且检测到特定的SSID时，应该会发生这种情况。

CaptiveNetwork编程接口允许应用程序与Captive Network Support交互，Captive Network Support是负责在提供Internet访问之前检测需要用户交互的网络的系统组件。 这些网络是机场和酒店等公共场所中最常见的WiFi热点。

首先，您必须检查网络是否可用

wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
        if (!wifiManager.isWifiEnabled()) {
            wifiManager.setWifiEnabled(true);
        }
            wifiResultsReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                context.unregisterReceiver(wifiResultsReceiver);
                List<ScanResult> wifiList;
                wifiList = wifiManager.getScanResults();
                for (int i = 0; i < wifiList.size(); i++) {
                    String[] networkInfo = wifiList.get(i).toString().split(",");
                    if (networkInfo[0].trim().equals(YOUR_SSID)) {
                       //Check if your ssid is available &
                        connect();
                    }
            }
        };
        context.registerReceiver(wifiResultsReceiver, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));

        wifiManager.startScan();

然后，如果网络可用，则可以连接到您的SSID（这是我的配置之一）：

public static WifiConfiguration getConnectionConfig(Context context, String ssidName) {
        Validator.validateArgument(context, "Context can't be null");
        WifiManager wifiManager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
        if (!wifiManager.isWifiEnabled()) wifiManager.setWifiEnabled(true);
        WifiConfiguration wifiConfig = new WifiConfiguration();
        wifiConfig.SSID = ssidName;
        List<WifiConfiguration> curentList = wifiManager.getConfiguredNetworks();
        if (curentList != null && !curentList.isEmpty()) {
            curentList.removeAll(Collections.singleton(null));
            for (int i = 0; i < curentList.size(); i++) {
                WifiConfiguration item = curentList.get(i);
                if (ssidName.equals(item.SSID)) {
                    wifiManager.removeNetwork(item.networkId);
                }
            }
        }
        wifiConfig.status = WifiConfiguration.Status.DISABLED;
        wifiConfig.priority = 100;
        wifiConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
        wifiConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
        wifiConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
        wifiConfig.allowedAuthAlgorithms.clear();
        wifiConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
        wifiConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
        wifiConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
        wifiConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
        wifiConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        wifiConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
        return wifiConfig;
    }

private void connect() {
wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
int networkID = wifiManager.addNetwork(getConnectionConfig(context, YOUR_SSID));
     wifiManager.disconnect();
     wifiManager.enableNetwork(networkID, true);
     wifiManager.reconnect();
}

不要忘记在AndroidManifest上添加权限

PS：三星设备在4.4和早期版本的SSID扫描中存在一些问题，请小心。 PPS：对于身份验证，您必须对AP连接使用特定的配置（以我为例）。 问候
