You can use the connection.getNetCapabilities API provided by the @kit.NetworkKit module to obtain the network capability information. If the value of bearerTypes is 0, the network is a cellular network. Before using the API, you must declare the ohos.permission.GET_NETWORK_INFO permission.
The code snippet is as follows:
import { connection } from '@kit.NetworkKit';
// Check if the network is connected
connection.hasDefaultNet((error, data) => {
console.log('data: ' + data);
})
// Obtain network capability information
connection.getDefaultNet().then((netHandle) => {
connection.getNetCapabilities(netHandle, (error, data) => {
console.log(JSON.stringify(error));
console.log(JSON.stringify(data));
})
}) Reference
