如何从NodeJS中的IBM Object Store Bucket读取.zip或.gz文件？

const COS = require('ibm-cos-sdk');
const fs = require('fs');

const config = {
  endpoint: 'your-endpoint',
  apiKeyId: 'your-api-key',
  ibmAuthEndpoint: 'your-auth-endpoint',
  serviceInstanceId: 'your-instance-id',
};

const cosClient = new COS.S3(config);

const params = {
  Bucket: 'your-bucket-name',
  Key: 'path/to/your-file.zip',
};

cosClient.getObject(params, (err, data) => {
  if (err) {
    console.error(err);
  } else {
    // 处理获取到的文件数据
    const fileData = data.Body;
    // ...
  }
});

const AdmZip = require('adm-zip');

const zip = new AdmZip(fileData);
const zipEntries = zip.getEntries();

zipEntries.forEach((entry) => {
  // 处理每个文件条目
  const entryData = entry.getData();
  // ...
});

const zlib = require('zlib');

zlib.gunzip(fileData, (err, uncompressedData) => {
  if (err) {
    console.error(err);
  } else {
    // 处理解压缩后的数据
    // ...
  }
});
