Upload and Download Subsystem Changelog

cl.request.2 request API Change

Deleted the beta APIs in API version 9:

1. function download(context: BaseContext, config: DownloadConfig, callback: AsyncCallback<DownloadTask>): void;
2. function download(context: BaseContext, config: DownloadConfig): Promise<DownloadTask>;
3. function upload(context: BaseContext, config: UploadConfig, callback: AsyncCallback<UploadTask>): void;
4. function upload(context: BaseContext, config: UploadConfig): Promise<UploadTask>;

Change Impact

The application developed based on an earlier version in the stage model needs to be adapted to the new APIs. Otherwise, the original service logic will be affected.

Key API/Component Changes

Adaptation Guide

Call the new APIs. The following uses downloadFile as an example to show how it is called in the new version:

try {
    request.downloadFile(globalThis.abilityContext, { url: 'https://xxxx/xxxxx.hap',
        filePath: 'xxx/xxxxx.hap'}, (err, data) => {
        if (err) {
            console.error('Failed to request the download. Cause: ' + JSON.stringify(err));
            return;
        }
    });
} catch (err) {
    console.log("downloadFile callback fail." + "errCode:" + err.code + ",errMessage:" + err.message);
}
