Usage

Obtaining IP Addresses of the Default Network by Resolving the Domain Name (Promise Mode)

• Example

  import net_connection from "@ohos.net.connection" 

  net_connection.getAddressesByName("www.example.com").then(function (addresses) {
    console.log(JSON.stringify(addresses))
  })

Registering an Observer for the Default Network

• Example

  import net_connection from "@ohos.net.connection" 

  let netConnection = net_connection.createNetConnection()
  netConnection.on('netAvailable', function(data) {
    console.log(JSON.stringify(data))
  })
  netConnection.register(function (error) {
    if (error) {
      console.log(JSON.stringify(error))
    }
  })
