本文介绍删除对象的常用场景代码。

删除目录

以下代码用于删除指定目录下 exampledir/ 的对象。

import { TosClient, TosClientError, TosServerError } from '@volcengine/tos_harmonyos_sdk';

// 创建客户端
const client = new TosClient({
  accessKeyId: "Provide your ak", 
  accessKeySecret: "Provide your sk", 
  securityToken: 'Provide your securityToken',
  region: "Provide your region", // 填写 Bucket 所在地域。以华北2（北京)为例，"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 = 'harmonyos-sdk-test-bucket';
async function main() {
  try {
    // 删除目录下所有文件
    const dir = 'exampledir/';
    let continuationToken = '';
    while (true) {
      const res = await client.listObjectsType2({
        Bucket: bucketName,
        MaxKeys: 1000,
        ContinuationToken: continuationToken,
        Prefix: dir,
      });

      for (const obj of res.Contents) {
        const res2 = await client.deleteObject({
          Bucket: bucketName,
          Key: obj.Key,
        });
        console.log('deleteObject %s Request ID:', obj.Key, res2.RequestId);
      }
      if (!res.IsTruncated) {
        break;
      }
      continuationToken = res.NextContinuationToken ?? '';
    }
  } catch (error) {
    handleError(error);
  }
}

main();

清空桶

以下代码用于清空整个桶，包括删除所有对象、删除所有未合并的对象。

import { TosClient, TosClientError, TosServerError } from '@volcengine/tos_harmonyos_sdk';

// 创建客户端
const client = new TosClient({
  accessKeyId: "Provide your ak", 
  accessKeySecret: "Provide your sk", 
  securityToken: 'Provide your securityToken',
  region: "Provide your region", // 填写 Bucket 所在地域。以华北2（北京)为例，"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);
  }
}

async function main() {
  try {
    let continuationToken = '';
    while (true) {
      const res = await client.listObjectsType2({
        Bucket: bucketName,
        MaxKeys: 1000,
        ContinuationToken: continuationToken,
      });

      for (const obj of res.Contents) {
        const res2 = await client.deleteObject({
          Bucket: bucketName,
          Key: obj.Key,
        });
        console.log('deleteObject %s Request ID:', obj.Key, res2.RequestId);
      }
      if (!res.IsTruncated) {
        break;
      }
      continuationToken = res.NextContinuationToken ?? '';
    }
    let keyMarker2 = '';
    let uploadIdMarker = '';
    // 删除所有未合并的对象
    while (true) {
      const res = await client.listMultipartUploads({
        Bucket: bucketName,
        MaxUploads: 1000,
        KeyMarker: keyMarker2,
        UploadIdMarker: uploadIdMarker,
      });
      for (const upload of res.Uploads) {
        const res2 = await client.abortMultipartUpload({
          Bucket: bucketName,
          Key: upload.Key,
          UploadID: upload.UploadId,
        });
        console.log('abortMultipartUpload uploadId: %s, requestId: %s', upload.UploadId, res2.RequestId);
      }
      if (!res.IsTruncated) {
        break;
      }
      keyMarker2 = res.NextKeyMarker ?? '';
      uploadIdMarker = res.NextUploadIdMarker ?? '';
    }
    
  } catch (error) {
    handleError(error);
  }
}

main();

清空开启多版本的桶

以下代码用于清空整个开启多版本桶的示例代码，包括删除所有对象的多个版本、删除删除标记的多个版本、删除所有未合并的对象。

import { TosClient, TosClientError, TosServerError } from '@volcengine/tos_harmonyos_sdk';

// 创建客户端
const client = new TosClient({
  accessKeyId: "Provide your ak", 
  accessKeySecret: "Provide your sk", 
  securityToken: 'Provide your securityToken',
  region: "Provide your region", // 填写 Bucket 所在地域。以华北2（北京)为例，"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);
  }
}

async function main() {
  try {
    const bucketName = 'harmonyos-sdk-test-bucket';

    // 删除桶中所有对象
    let keyMarker = '';
    let versionIdMarker = '';
    while (true) {
      const res = await client.listObjectVersions({
        MaxKeys: 1000,
        Bucket: bucketName,
        KeyMarker: keyMarker,
        VersionIDMarker: versionIdMarker,
      });

      // 删除多版本对象
      for (const object of res.Versions) {
        const res2 = await client.deleteObject({
          Bucket: bucketName,
          Key: object.Key,
          VersionID: object.VersionId,
        });
        console.log('deleteObject %s Request ID:', object.Key, res2.RequestId);
      }

      // 删除标记信息
      for (const markers of res.DeleteMarkers) {
        const res2 = await client.deleteObject({
          Bucket: bucketName,
          Key: markers.Key,
          VersionID: markers.VersionId,
        });
        console.log('deleteObject DeleteMarker %s Request ID:', markers.Key, res2.RequestId);
      }
      if (!res.IsTruncated) {
        break;
      }
      keyMarker = res.NextKeyMarker ?? '';
      versionIdMarker = res.NextVersionIdMarker ?? '';
    }

    let keyMarker2 = '';
    let uploadIdMarker = '';
    // 删除所有未合并的对象
    while (true) {
      const res = await client.listMultipartUploads({
        Bucket: bucketName,
        MaxUploads: 1000,
        KeyMarker: keyMarker2,
        UploadIdMarker: uploadIdMarker,
      });
      for (const upload of res.Uploads) {
        const res2 = await client.abortMultipartUpload({
          Bucket: bucketName,
          Key: upload.Key,
          UploadID: upload.UploadId,
        });
        console.log('abortMultipartUpload uploadId: %s, requestId: %s', upload.UploadId, res2.RequestId);
      }
      if (!res.IsTruncated) {
        break;
      }
      keyMarker = res.NextKeyMarker ?? '';
      uploadIdMarker = res.NextUploadIdMarker ?? '';
    }
  } catch (error) {
    handleError(error);
  }
}

main();
