AmazonS3EncryptionClient

public AmazonS3EncryptionClient(EncryptionMaterials encryptionMaterials)

Constructs a new Amazon S3 Encryption client that will make anonymous requests to Amazon S3. If AmazonS3Client.getObject(String, String) is called, the object contents will be decrypted with the encryption materials provided.

Only a subset of the Amazon S3 API will work with anonymous (i.e. unsigned) requests, but this can prove useful in some situations. For example:

• If an Amazon S3 bucket has Permission.Read permission for the GroupGrantee.AllUsers group, anonymous clients can call AmazonS3Client.listObjects(String) to see what objects are stored in a bucket.
• If an object has Permission.Read permission for the GroupGrantee.AllUsers group, anonymous clients can call AmazonS3Client.getObject(String, String) and AmazonS3Client.getObjectMetadata(String, String) to pull object content and metadata.
• If a bucket has Permission.Write permission for the GroupGrantee.AllUsers group, anonymous clients can upload objects to the bucket.

putObject

public PutObjectResult putObject(PutObjectRequest putObjectRequest)
                          throws AmazonClientException,
                                 AmazonServiceException

インタフェースからコピーされた説明: AmazonS3

Uploads a new object to the specified Amazon S3 bucket. The PutObjectRequest contains all the details of the request, including the bucket to upload to, the key the object will be uploaded under, and the file or input stream containing the data to upload.

Amazon S3 never stores partial objects; if during this call an exception wasn't thrown, the entire object was stored.

Depending on whether a file or input stream is being uploaded, this method has slightly different behavior.

When uploading a file:

• The client automatically computes a checksum of the file. Amazon S3 uses checksums to validate the data in each file.
• Using the file extension, Amazon S3 attempts to determine the correct content type and content disposition to use for the object.

When uploading directly from an input stream:

• Be careful to set the correct content type in the metadata object before directly sending a stream. Unlike file uploads, content types from input streams cannot be automatically determined. If the caller doesn't explicitly set the content type, it will not be set in Amazon S3.
• Content length must be specified before data can be uploaded to Amazon S3. Amazon S3 explicitly requires that the content length be sent in the request headers before it will accept any of the data. If the caller doesn't provide the length, the library must buffer the contents of the input stream in order to calculate it.

If versioning is enabled for the specified bucket, this operation will never overwrite an existing object with the same key, but will keep the existing object as an older version until that version is explicitly deleted (see AmazonS3.deleteVersion(String, String, String).

If versioning is not enabled, this operation will overwrite an existing object with the same key; Amazon S3 will store the last write request. Amazon S3 does not provide object locking. If Amazon S3 receives multiple write requests for the same object nearly simultaneously, all of the objects might be stored. However, a single object will be stored with the final write request.

When specifying a location constraint when creating a bucket, all objects added to the bucket are stored in the bucket's region. For example, if specifying a Europe (EU) region constraint for a bucket, all of that bucket's objects are stored in the EU region.

The specified bucket must already exist and the caller must have Permission.Write permission to the bucket to upload an object.

インタフェースからコピーされた説明: AmazonS3

Gets the object stored in Amazon S3 under the specified bucket and key. Returns null if the specified constraints weren't met.

Callers should be very careful when using this method; the returned Amazon S3 object contains a direct stream of data from the HTTP connection. The underlying HTTP connection cannot be closed until the user finishes reading the data and closes the stream. Callers should therefore:

• Use the data from the input stream in Amazon S3 object as soon as possible,
• Close the input stream in Amazon S3 object as soon as possible.

If callers do not follow those rules, then the client can run out of resources if allocating too many open, but unused, HTTP connections.

To get an object from Amazon S3, the caller must have Permission.Read access to the object.

If the object fetched is publicly readable, it can also read it by pasting its URL into a browser.

When specifying constraints in the request object, the client needs to be prepared to handle this method returning null if the provided constraints aren't met when Amazon S3 receives the request.

If the advanced options provided in GetObjectRequest aren't needed, use the simpler AmazonS3.getObject(String bucketName, String key) method.

Instead of using AmazonS3.getObject(GetObjectRequest), use this method to ensure that the underlying HTTP stream resources are automatically closed as soon as possible. The Amazon S3 clients handles immediate storage of the object contents to the specified file.

To get an object from Amazon S3, the caller must have Permission.Read access to the object.

インタフェースからコピーされた説明: AmazonS3

Completes a multipart upload by assembling previously uploaded parts.

You first upload all parts using the AmazonS3.uploadPart(UploadPartRequest) method. After successfully uploading all individual parts of an upload, you call this operation to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the CompleteMultipartUpload request, you must provide the parts list. For each part in the list, you provide the part number and the ETag header value, returned after that part was uploaded.

Processing of a CompleteMultipartUpload request may take several minutes to complete.

Initiates a multipart upload and returns an InitiateMultipartUploadResult which contains an upload ID.

                                   AmazonServiceException

Uploads a part in a multipart upload. You must initiate a multipart upload before you can upload any part.

Your UploadPart request must include an upload ID and a part number. The upload ID is the ID returned by Amazon S3 in response to your Initiate Multipart Upload request. Part number can be any number between 1 and 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being uploaded. If you upload a new part using the same part number that was specified in uploading a previous part, the previously uploaded part is overwritten.

To ensure data is not corrupted traversing the network, specify the Content-MD5 header in the Upload Part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error.

When you upload a part, the returned UploadPartResult contains an ETag property. You should record this ETag property value and the part number. After uploading all parts, you must send a CompleteMultipartUpload request. At that time Amazon S3 constructs a complete object by concatenating all the parts you uploaded, in ascending order based on the part numbers. The CompleteMultipartUpload request requires you to send all the part numbers and the corresponding ETag values.

NOTE: Because the encryption process requires context from block N-1 in order to encrypt block N, parts uploaded with the AmazonS3EncryptionClient (as opposed to the normal AmazonS3Client) must be uploaded serially, and in order. Otherwise, the previous encryption context isn't available to use when encrypting the current part.
