什么是安卓的CaptiveNetwork API (iOS)？

我希望注册用户能够连接到WiFi网络并无缝地进行身份验证。当用户运行应用程序并检测到特定的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支持交互，该系统组件负责在提供internet访问之前检测需要用户交互的网络。这些网络通常是机场和酒店等公共场所的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();如果网络可用，您可以连接到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();
}不要忘记添加对AndroidManifest的权限
P.S:三星设备在4.4和早期版本的SSID扫描中有一些问题，请小心。P.P.S:对于auth，您必须对AP连接使用特定的配置，在我的示例中，它是打开的。问候
