Simple Example of how to get the un-presigned s3 object url using the golang aws sdk v2
问题
我在Google/Stack Overflow上看到很多使用s3client.GetRequestObject的示例，但这个方法在SDK的v2版本中已被移除。
client := s3.NewFromConfig(cfg)
params := &s3.GetObjectInput{
Bucket: aws.String(bucket),
Key: aws.String(key),
}
req, _ := client.GetRequestObject(params)
我查看了SDK v2的示例，但没有找到一个明显的示例来完成这个操作。
我不想下载文件，只是提供一个下载链接。

I see lots of example on google/stackoverflow using s3client.GetRequestObject which is now removed from v2 of the sdk
client := s3.NewFromConfig(cfg)
params := &s3.GetObjectInput{
Bucket: aws.String(bucket),
Key: aws.String(key),
}
req, _ := client.GetRequestObject(params)

I looked through the sdk v2 examples:
https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/gov2/s3/
And nothing stands out to me as an example of how to do this.

以下是获取带有过期时间的对象的预签名URL的示例：
s3client := s3.NewFromConfig(cfg)
presignClient := s3.NewPresignClient(s3client)
presignedUrl, err := presignClient.PresignGetObject(context.Background(),
&s3.GetObjectInput{
Bucket: aws.String("bucket-name"),
Key: aws.String("key-name"),
},
s3.WithPresignExpires(time.Minute*15))
if err != nil {
log.Fatal(err)
}
fmt.Println(presignedUrl.URL)

Here is an example of getting presigned URL for an object with an expiration time:
s3client := s3.NewFromConfig(cfg)
presignClient := s3.NewPresignClient(s3client)
presignedUrl, err := presignClient.PresignGetObject(context.Background(),
&s3.GetObjectInput{
Bucket: aws.String("bucket-name"),
Key: aws.String("key-name"),
},
s3.WithPresignExpires(time.Minute*15))
if err != nil {
log.Fatal(err)
}
fmt.Println(presignedUrl.URL)
