Upload and Download Subsystem Changelog
cl.request.2 request API Change
Deleted the beta APIs in API version 9:
- function download(context: BaseContext, config: DownloadConfig, callback: AsyncCallback<DownloadTask>): void;
- function download(context: BaseContext, config: DownloadConfig): Promise<DownloadTask>;
- function upload(context: BaseContext, config: UploadConfig, callback: AsyncCallback<UploadTask>): void;
- 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
Module | Class | Method/Attribute/Enum/Constant | Change Type |
---|---|---|---|
ohos.request | request | function download(context: BaseContext, config: DownloadConfig, callback: AsyncCallback<DownloadTask>): void; | Deleted |
ohos.request | request | function download(context: BaseContext, config: DownloadConfig): Promise<DownloadTask>; | Deleted |
ohos.request | request | function upload(context: BaseContext, config: UploadConfig, callback: AsyncCallback<UploadTask>): void; | Deleted |
ohos.request | request | function upload(context: BaseContext, config: UploadConfig): Promise<UploadTask>; | Deleted |
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);
}
