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。 阅读java doc以获取详细信息

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);
