先通过getNetCapabilities去获取网络的类型，判断默认网络是Wi-Fi还是蜂窝。
如果是Wi-Fi，则直接确认网络类型是Wi-Fi。如果是在蜂窝连接情况下，可以调用radio.getSignalInformation获取指定SIM卡槽对应的注册网络信号强度信息列表，返回SignalInformation对象的数组，其中，返回的signalType代表网络类型NetworkType，signalType的值对应网络类型如下：
具体可参考如下示例代码：
import { connection } from '@kit.NetworkKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { radio } from '@kit.TelephonyKit';
@Entry
@Component
struct Index {
build() {
Column() {
Button('获取网络类型')
.type(ButtonType.Normal)
.width(200)
.height(200)
.onClick(() => {
connection.getDefaultNet().then((netHandle: connection.NetHandle) => {
if (netHandle.netId == 0) {
// When there is currently no connected network, the obtained netHandler's netid is 0, which belongs to an abnormal scenario.
// Here, some processing mechanisms can be added according to the actual situation.
return;
}
// Obtain the capability information of the network corresponding to netHandle
connection.getNetCapabilities(netHandle, (error: BusinessError, data: connection.NetCapabilities) => {
if (error) {
console.error(`Failed to get net capabilities. Code:${error.code}, message:${error.message}`);
return;
}
console.info("Succeeded to get data: " + JSON.stringify(data));
if (data.bearerTypes[0] == 1) {
// console.info("Wi Fi network");
} else if (data.bearerTypes[0] == 0) {
// console.info("Cellular Network");
let slotId: number = 0; // Slot ID, -0: Slot 1, -1: Slot 2
radio.getSignalInformation(slotId, (err: BusinessError, data: Array<radio.SignalInformation>) => {
if (err) {
console.error(`getSignalInformation failed, callback: err->${JSON.stringify(err)}`);
return;
}
console.info(`getSignalInformation success, callback: data->${JSON.stringify(data)}`);
// Return an array of SignalInformation objects, where the returned signalType represents the network type NetworkType
});
}
})
}).catch((error: BusinessError) => {
console.error('error: ' + JSON.stringify(error));
});
})
}
