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.

Key API/Component Changes

Module	Class	Method/Attribute/Enumeration/Constant	Change Type
ohos.request	request	function download(context: BaseContext, config: DownloadConfig, callback: AsyncCallback): void;	Deleted.
ohos.request	request	function download(context: BaseContext, config: DownloadConfig): Promise;	Deleted.
ohos.request	request	function upload(context: BaseContext, config: UploadConfig, callback: AsyncCallback): void;	Deleted.

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);
}
