以下代码仅适用于从S3中的存储桶下载文本文件。这不适用于图像。有使用AWS开发工具包管理下载/类型的简便方法吗？文档中包含的示例并不明显。谢谢！
AWSCredentials myCredentials = new BasicAWSCredentials(
String.valueOf(Constants.act), String.valueOf(Constants.sk));
AmazonS3Client s3Client = new AmazonS3Client(myCredentials);
S3Object object = s3Client.getObject(new GetObjectRequest("bucket", "file"));
BufferedReader reader = new BufferedReader(new InputStreamReader(
object.getObjectContent()));
File file = new File("localFilename");
Writer writer = new OutputStreamWriter(new FileOutputStream(file));
while (true) {
String line = reader.readLine();
if (line == null)
break;
writer.write(line + "\n");
}
writer.close();
而不是Reader和Writer类，你应该使用InputStream和OutputStream类：
InputStream reader = new BufferedInputStream(
object.getObjectContent());
File file = new File("localFilename");
OutputStream writer = new BufferedOutputStream(new FileOutputStream(file));
int read = -1;
while ( ( read = reader.read() ) != -1 ) {
writer.write(read);
}
writer.flush();
writer.close();
reader.close();
