HarmonyOS 鸿蒙Next中WifiEapConfig实例有没有wifiEapConfig的使用实例啊，想实现鸿蒙手机下，通过证书的方式连接wifi,实现wifi准入的功能。

开发者您好，您可以参考添加候选网络和连接候选网络的流程来实现wifiEapConfig的使用实例，相关代码实现如下：

try {
      let eapConfig: wifiManager.WifiEapConfig = {
        eapMethod: wifiManager.EapMethod.EAP_NONE,
        phase2Method: wifiManager.Phase2Method.PHASE2_NONE,
        identity: '',
        anonymousIdentity: '',
        password: '',
        caCertAlias: '',
        caPath: '',
        clientCertAlias: '',
        certEntry: new Uint8Array(),
        certPassword: '',
        altSubjectMatch: '',
        domainSuffixMatch: '',
        realm: '',
        plmn: '',
        eapSubId: 0
      }
      let config:wifiManager.WifiDeviceConfig = {
        ssid : "****",
        preSharedKey : "****",
        securityType : 5,
        eapConfig: eapConfig
      }
      // 添加候选网络
      wifiManager.addCandidateConfig(config).then(result => {
        console.info("result:" + JSON.stringify(result));
        // 连接候选网络
        try {
          wifiManager.connectToCandidateConfig(result);
        }catch(error){
          console.error("failed:" + JSON.stringify(error));
        }
      }).catch((err:number) => {
        console.error("failed:" + JSON.stringify(err));
      });
    }catch(error){
      console.error("failed:" + JSON.stringify(error));
    }

wifiEapConfig的参考配置可以参考这个文档：wifiEapConfig。开发者可以看下上诉的方案是否可以解决您的问题，如果仍未解决，请及时反馈一下问题详情。

HarmonyOS Next中WifiEapConfig类详解

WifiEapConfig是用于配置WPA/WPA2企业级Wi-Fi认证参数的类，继承自WifiSecurityConfig。它定义了EAP认证方法、阶段2认证方式、身份信息、CA证书等关键属性。

主要属性

eapMethod：EAP类型。
phase2Method：第二阶段认证。
identity：身份标识。
anonymousIdentity：匿名身份标识。
caCertAliases：CA证书别名。
caCertPath：CA证书路径。
caCert：CA证书数据。
clientCertAlias：客户端证书别名。
password：密码。

sinazl 4楼

在HarmonyOS Next中，使用WifiEapConfig进行证书认证的WIFI连接，核心步骤是构建配置并应用。以下是一个关键代码实例：

导入模块：

import { wifiManager } from '@kit.ConnectivityKit';
import { BusinessError } from '@kit.BasicServicesKit';

构建EAP配置：

// 创建WifiEapConfig实例
let eapConfig: wifiManager.WifiEapConfig = {
  eapMethod: wifiManager.EapMethod.EAP_TLS, // 使用TLS方法
  identity: 'your_identity', // 用户标识
  anonymousIdentity: 'anonymous', // 匿名标识（可选）
  password: '', // TLS通常不需要密码
  caCertAliases: ['ca_cert_alias'], // CA证书别名数组
  clientCertAlias: 'client_cert_alias', // 客户端证书别名
  certEntry: wifiManager.CertEntry.UICC, // 证书存储位置
  certPassword: 'your_cert_password', // 证书密码
  phase2Method: wifiManager.Phase2Method.NONE // 第二阶段认证方法
};

配置WIFI并连接：

// 创建WifiDeviceConfig
let config: wifiManager.WifiDeviceConfig = {
  ssid: 'Your_SSID',
  bssid: 'Your_BSSID',
  securityType: wifiManager.SecurityType.EAP,
  eapConfig: eapConfig
};

// 添加配置
wifiManager.addDeviceConfig(config, (err: BusinessError, result: number) => {
  if (err) {
    console.error('Add config failed: ' + JSON.stringify(err));
    return;
  }
  console.log('Config added, networkId: ' + result);
  
  // 连接网络
  wifiManager.connectToNetwork(result, (err: BusinessError) => {
    if (err) {
      console.error('Connect failed: ' + JSON.stringify(err));
      return;
    }
    console.log('Connect successfully');
  });
});

关键点说明：

eapMethod：证书认证通常选择EAP_TLS
caCertAliases和clientCertAlias：需要提前将CA证书和客户端证书导入系统，并获取其别名
certEntry：指定证书存储位置，如UICC（通用集成电路卡）或UFS（通用闪存存储）
确保证书已正确安装并具有相应访问权限

此配置适用于需要802.1X证书认证的企业WIFI网络，实现安全的网络准入控制。
