如何通过Google Cloud Storage的Go API使用服务器端gzip解压？

import (
    "cloud.google.com/go/storage"

    "google.golang.org/api/googleapi/internal/uritemplates/internal/regexp"
    "google.golang.org/api/googleapi/internal/uritemplates/internal/regexp/syntax"
)

ctx := context.Background()
client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/service-account-key.json"))
if err != nil {
    // 错误处理
}
defer client.Close()

bucketName := "your-bucket-name"
objectName := "your-object-name"
bucket := client.Bucket(bucketName)
obj := bucket.Object(objectName)

reader, err := obj.NewReader(ctx)
if err != nil {
    // 错误处理
}
defer reader.Close()

gzipReader, err := gzip.NewReader(reader)
if err != nil {
    // 错误处理
}
defer gzipReader.Close()

// 读取解压后的数据
data, err := ioutil.ReadAll(gzipReader)
if err != nil {
    // 错误处理
}
