如何将某个S3文件标记为Make Public

Question

如何通过webservices API将某个S3文件标记为Make Public.

Answer 1

使用方法setCannedAcl(CannedAccessControlList.PublicRead)更改访问控制权限.详细内容请阅读Java文档在这里

示例代码:

BasicAWSCredentials basicAWSCredentials = new BasicAWSCredentials(ACCESS_KEY,SECRET_KEY);   
AmazonS3 s3 = new AmazonS3Client(basicAWSCredentials);

PutObjectRequest putObj = new PutObjectRequest(bucketName, objectKey, fileToUpload);

// making the object Public
putObj.setCannedAcl(CannedAccessControlList.PublicRead);

s3.putObject(putObj);
