android - 有没有办法通过 EAP-TTLS 以编程方式连接到 Passpoint/Hotspot2.0 网络？

Question

我正在尝试在 Android 应用程序中创建 WifiConfiguration 对象或 PasspointConfiguration 对象，以便在启用后将设备连接到 Passpoint 网络。

我尝试通过构建 WifiConfiguration 对象并将其添加到 WifiManager，然后启用它来进行连接。

我还尝试构建 PasspointConfiguration 对象，但是当我尝试使用 PasspointConfiguration 对象运行 WifiManager.addOrUpdatePasspointConfiguration() 时，应用程序崩溃并出现 IllegalArgumentException。我假设这是一个无效的配置问题。

// WifiConfiguration/WifiEnterpriseConfiguration approach
WifiConfiguration wc = new WifiConfiguration();
wc.status = WifiConfiguration.Status.ENABLED;
wc.isHomeProviderNetwork = true;
wc.FQDN = this.domain;
wifiEnterpriseConfig.setIdentity(user);
wifiEnterpriseConfig.setPassword(key);
wifiEnterpriseConfig.setAnonymousIdentity(this.outerID);
wifiEnterpriseConfig.setRealm(this.realm);
wifiEnterpriseConfig.setDomainSuffixMatch(this.domain);
wifiEnterpriseConfig.setEapMethod(this.eapMethod);
wifiEnterpriseConfig.setPhase2Method(this.phase2Auth);
wifiEnterpriseConfig.setCaCertificate(this.cert);

wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);

wc.enterpriseConfig = wifiEnterpriseConfig;

wifiManager.disconnect();
this.networkID = wifiManager.addNetwork(wc);
wifiManager.enableNetwork(this.networkID, true);

// PasspointConfiguration approach
Credential.UserCredential userCredential = new Credential.UserCredential();
userCredential.setEapType(21);
userCredential.setPassword(key);
userCredential.setUsername(user);
userCredential.setNonEapInnerMethod("MS-CHAP-V2");

Credential credential = new Credential();
credential.setRealm(this.realm);
credential.setUserCredential(userCredential);
credential.setCertCredential(null);
credential.setCaCertificate(null);
credential.setClientPrivateKey(null);
credential.setClientCertificateChain(null);

HomeSp homeSp = new HomeSp();
homeSp.setFqdn(this.domain);
homeSp.setFriendlyName(this.friendlyName);

PasspointConfiguration passpointConfiguration = new PasspointConfiguration();
passpointConfiguration.setCredential(credential);
passpointConfiguration.setHomeSp(homeSp);

wifiManager.addOrUpdatePasspointConfiguration(passpointConfiguration);

我希望应用程序在将其中一项配置添加到 WifiManager 后将设备连接到 Passpoint/Hotspot2.0 网络。

第一种方法不会产生错误，但不会将应用程序连接到网络。

以下是来自 PasspointConfiguration IllegalArgumentException 的堆栈跟踪:

Answer 1

userCredential.setPassword(key) 中使用的 key 在设置为 userCredential 之前必须采用 Base 64 编码。
