php - Putting multiple objects in Amazon S3 with different meta data fails -

i've got array of file information being looped through , using aws php 2 skd upload contents of these files cloud, works brilliantly until try , add meta data, @ point, adds the metadata first object created, after following error message:

fatal error: uncaught aws\s3\exception\signaturedoesnotmatchexception: aws error code: signaturedoesnotmatch, status code: 403, aws request id: 8fc9360f2eb687ee, aws error type: client, aws error message: request signature calculated not match signature provided. check key , signing method., user-agent: aws-sdk-php2/2.2.1 guzzle/3.3.1 curl/7.24.0 php/5.3.13 thrown in d:\inetpub\wwwroot\thirdparty_resources\aws_sdk2\aws\aws-sdk-php\src\aws\common\exception\namespaceexceptionfactory.php on line 89

i've cropped code loop highlight area being naughty.

foreach($afiles $afile) { $arr_objectmeta = array(     'originalfilename'  => $afile['filename'] ,   'description'       => $afile['filedesc'] ,   'keywords'      => $afile['filekeyw'] );  // file upload $obj_fileupload = $obj_s3->putobject($sbucket, $sbucketfolder . $sfilenametosave, $sfile, 'public-read', $arr_objectmeta); if($obj_fileupload) {     $files_uploaded++; } else {     $files_not_uploaded++; }  // clear file upload s3 response object unset($obj_fileupload);  // delete downloaded file unlink($sserveruploadfolder.$sfilenametosave); } 

so second time around loop, seems bomb because of different meta values. when meta data same, loop executes without issue. help/pointers great.

you might confusing putobject method method upload helper method.

the upload helper method available of version 2.4 of sdk. using upload method following:

try {     $skey = $sbucketfolder . $sfilenametosave;     $obj_fileupload = $obj_s3->upload($sbucket, $skey, $sfile, 'public-read', array(         'metadata' => $arr_objectmeta     ));     $files_uploaded++; } catch (\aws\s3\exception\s3exception $e) {     $files_not_uploaded++; } 

you can same thing putobject method well, more verbose.

try {     $obj_fileupload = $obj_s3->putobject(array(         'bucket'     => $sbucket         'key'        => $sbucketfolder . $sfilenametosave,         'sourcefile' => $sfile,         'acl'        => 'public-read'         'metadata'   => $arr_objectmeta     ));     $files_uploaded++; } catch (\aws\s3\exception\s3exception $e) {     $files_not_uploaded++; }
