Upload and Download Subsystem Changelog

cl.request.2 Upload and Download API Change

Deleted the beta APIs in API version 9:

function download(context: BaseContext, config: DownloadConfig, callback: AsyncCallback): void;
function download(context: BaseContext, config: DownloadConfig): Promise;
function upload(context: BaseContext, config: UploadConfig, callback: AsyncCallback): void;
function upload(context: BaseContext, config: UploadConfig): Promise;

Change Impact

The application developed based on the Stage mode of earlier versions needs to be adapted. Otherwise, the service logic will be affected.

Adaptation Guide

The following sample code shows how to call downloadFile 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);
}
