如果您需要在 Bucket 中对文件进行重命名，您可以通过 CopyObject 接口将源对象拷贝至目标对象，然后通过 DeleteObject 接口删除源对象。
以下代码用于将存储桶中对象 src-object 重命名为 dest-object。
// 导入 SDK, 当 TOS Node.JS SDK 版本小于 2.5.2 请把下方 TosClient 改成 TOS 导入
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';
// 创建客户端
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
region: "Provide your region", // 填写 Bucket 所在地域。以华北2（北京)为例，则 "Provide your region" 填写为 cn-beijing。
endpoint: "Provide your endpoint", // 填写域名地址
});
function handleError(error) {
if (error instanceof TosClientError) {
console.log('Client Err Msg:', error.message);
console.log('Client Err Stack:', error.stack);
} else if (error instanceof TosServerError) {
console.log('Request ID:', error.requestId);
console.log('Response Status Code:', error.statusCode);
console.log('Response Header:', error.headers);
console.log('Response Err Code:', error.code);
console.log('Response Err Msg:', error.message);
} else {
console.log('unexpected exception, message: ', error);
}
}
const bucketName = 'node-sdk-test-bucket';
async function main() {
try {
const srcObjectKey = 'src-object';
const dstObjectKey = 'dest-object';
// 将源对象复制到目标对象
const { requestId } = await client.copyObject({
bucket: bucketName,
key: dstObjectKey,
srcBucket: bucketName,
srcKey: srcObjectKey,
});
console.log('copyObject Request ID:', requestId);
// 删除源对象
const { requestId: requestId2 } = await client.deleteObject({
bucket: bucketName,
key: srcObjectKey,
});
console.log('deleteObject Request ID:', requestId2);
} catch (error) {
handleError(error);
}
}
main();
以下代码用于将指定存储桶中目录 exampledir1/ 重命名为 exampledir2/。
