如何获取一些应用开发必要信息

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)  
    })  
  }  
}

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  
    }

    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) {
