Upload and Download Changelog

cl.request.1 Changes of Error Code Definitions and API Names

• Processing of error codes is added to the upload and download APIs.
• Error information is returned via the error object in AsyncCallback or Promise. Wherein, parameter type or quantity error information is returned by throwing an exception.
• Some APIs are replaced with new APIs, but the parameters remain unchanged.

Change Impact

The application developed based on earlier versions needs to adapt the method for returning API error information. Otherwise, the original service logic will be affected.

Key API/Component Changes

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);
}
