140 You may also set Content-Encoding using "content_encoding", and
142 Content-Disposition using "content_disposition".
143 You may specify the S3 storage class by setting "storage_class" to
145 either "standard", "reduced_redundancy", "standard_ia", or
146 "onezone_ia"; the default is "standard".
147 You may set website-redirect-location object metadata by setting
149 "website_redirect_location" to either another object name in the same
150 bucket, or to an external URL.
151 put_filename
153 # upload a file
154 my $object = $bucket->object(
155 key => 'images/my_hat.jpg',
156 content_type => 'image/jpeg',
157 );
158 $object->put_filename('hat.jpg');
159 # upload a file if you already know its md5_hex and size
161 my $object = $bucket->object(
162 key => 'images/my_hat.jpg',
163 content_type => 'image/jpeg',
164 etag => $md5_hex,
165 size => $size,
166 );
167 $object->put_filename('hat.jpg');
168 You may also set Content-Encoding using "content_encoding", and
170 Content-Disposition using "content_disposition".
171 You may specify the S3 storage class by setting "storage_class" to
173 either "standard", "reduced_redundancy", "standard_ia", or
174 "onezone_ia"; the default is "standard".
175 You may set website-redirect-location object metadata by setting
177 "website_redirect_location" to either another object name in the same
178 bucket, or to an external URL.
179 User metadata may be set by providing a non-empty hashref as
181 "user_metadata".
182 query_string_authentication_uri
184 # use query string authentication, forcing download with custom filename
185 my $object = $bucket->object(
186 key => 'images/my_hat.jpg',
187 expires => '2009-03-01',
188 );
189 my $uri = $object->query_string_authentication_uri({
190 'response-content-disposition' => 'attachment; filename=abc.doc',
191 });
192 size
194 # show the size of an existing object (if fetched by listing
195 # a bucket)
196 print $object->size . "\n";
197 uri
199 # return the URI of a publically-accessible object
200 my $uri = $object->uri;
201 initiate_multipart_upload
203 #initiate a new multipart upload for this object
204 my $object = $bucket->object(
205 key => 'massive_video.avi'
206 );
207 my $upload_id = $object->initiate_multipart_upload;
208 put_part
210 #add a part to a multipart upload
211 my $put_part_response = $object->put_part(
212 upload_id => $upload_id,
213 part_number => 1,
214 value => $chunk_content,
215 );
216 my $part_etag = $put_part_response->header('ETag')
217 Returns an L<HTTP::Response> object. It is necessary to keep the ETags for
219 each part, as these are required to complete the upload.
220 complete_multipart_upload
222 #complete a multipart upload
223 $object->complete_multipart_upload(
224 upload_id => $upload_id,
225 etags => [$etag_1, $etag_2],
226 part_numbers => [$part_number_1, $part_number2],
227 );
228 The etag and part_numbers parameters are ordered lists specifying the part
230 numbers and ETags for each individual part of the multipart upload.
231 user_metadata
233 my $object = $bucket->object(key => $key);
234 my $content = $object->get; # or use $object->get_filename($filename)
235 # return the user metadata downloaded, as a hashref
237 my $user_metadata = $object->user_metadata;
238 To upload an object with user metadata, set "user_metadata" at
240 construction time to a hashref, with no "x-amz-meta-" prefixes on the
241 key names. When downloading an object, the "get", "get_decoded" and
242 "get_filename" ethods set the contents of "user_metadata" to the same
243 format.
