使用上传下载模块进行下载。最多支持4个任务同时下载。
参考代码如下：
import { request } from '@kit.BasicServicesKit';
import { BusinessError } from '@kit.BasicServicesKit';
// Using AppStore to store UIContext in ExitAbility
const context = AppStorage.get("context") as UIContext;
let downloadTask: request.DownloadTask;
try {
request.downloadFile(context.getHostContext(), { url: 'https://xxxx/xxxx.hap' }).then((data: request.DownloadTask) => {
downloadTask = data;
}).catch((err: BusinessError) => {
console.error(`Failed to request the download. Code: ${err.code}, message: ${err.message}`);
})
} catch (err) {
console.error(`Failed to request the download. err: ${JSON.stringify(err)}`);
