常见应用相关信息获取的方法（应用版本号、编译版本号、uuid、udid、idfv、局域网ip地址、ipv4与ipv6地址）

import { bundleManager } from '@kit.AbilityKit' 
 
@Entry 
@Component 
export struct ToLoginPage { 
build() { 
Column() { 
Text('hello') 
} 
} 
onPageShow() { 
 
} 
aboutToAppear(): void { 
bundleManager.getBundleInfoForSelf(bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION).then((info)=>{ 
console.info("info："+info.name) 
}) 
} 
}

获取IP信息,参照文档:https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-apis-net-connection-0000001774281662#ZH-CN_TOPIC_0000001774281662__connectionhasdefaultnetsync10 
获取手机IP信息样例代码： 
async function getLocalIp() { 
try { 
hilog.info(0x00000, TAG, '判断是否存在激活的网络连接'); 
let hasNet = connection.hasDefaultNetSync() 
if (hasNet) { 
hilog.info(0x00000, TAG, '存在默认激活的网络'); 
} else { 
hilog.error(0x00000, TAG, '不存在激活的网络'); 
return 
} 
 
let handleResult = await connection.getDefaultNet() 
if (handleResult) { 
let connectionProperties = await connection.getConnectionProperties(handleResult) 
if (connectionProperties && connectionProperties.linkAddresses) { 
connectionProperties.linkAddresses.forEach((address: connection.LinkAddress, index: number) => { 
hilog.info(0x00000, TAG, '索引：' + index + '，值：' + JSON.stringify(address)); 
}) 
} 
} 
} catch (e) { 
hilog.error(0x00000, TAG, `获取网络信息出现异常，异常信息 %{public}s`, JSON.stringify(e) ?? ''); 
} 
}
