上传下载子系统ChangeLog

OpenHarmony 3.2.8.1版本相较于OpenHarmony 3.2.beta3版本，request子系统的API变更如下

cl.request.1 错误码定义及API部分接口名称变更

新增上传下载接口的错误码处理。
错误信息通过AsyncCallback或Promise的error对象返回。其中，参数类型和数量错误信息，通过抛出异常的方式返回。
API部分接口需要用新的接口替换，参数不变。

变更影响

基于此前版本开发的应用，需适配变更后的新错误码和错误信息返回方式，否则会影响原有业务逻辑。

适配指导

以downloadFile为例，在新版本上需要使用如下方式进行调用：

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);
}
