i have uploaded thousands of images to amazon s3 and i need to change their content type to be image.
i know that i should do it when i try to putObject
$this->s3->putObject(array(
'Bucket' => $this->s3_bucket,
'Key' => $file_name,
'Body' => file_get_contents($tmp_name),
'ACL' => 'private',
'ContentType' => 'image/jpeg'
));
but i need to do so for all files that have been uploaded before.
thanks
Here is S3Object API:
http://docs.aws.amazon.com/AWSRubySDK/latest/AWS/S3/S3Object.html#copy_to-instance_method
Use the copy_to method。
Put content_type in "Options Hash", tested ok in Ruby.

I'm wanting to access the custom metadata for an object uploaded via the S3 multipart upload after firing off the completeMultipartUpload method.
I initiate a multipart S3 upload with some added custom metadata like so:
$response = $this->client->createMultipartUpload([
'Bucket' => $this->bucket,
'Key' => $key,
'ContentType' => $type,
'Expires' => 60,
'Metadata' => [
'file-guid' => $fileGuid,
],
]);
When I complete the multipart upload, I'm wanting to access the file-guid metadata and pass it along in my response.
$result = $this->client->completeMultipartUpload([
'Bucket' => $this->bucket,
'Key' => $key,
'UploadId' => $uploadId,
'MultipartUpload' => [
'Parts' => $parts,
],
]);
$fileGuid = $result['?'] // Couldn't find the metadata in the result.
return response()->json(['file-guid' => $fileGuid]);
I've checked the S3 object after it's been uploaded and it shows the custom metadata, but I don't see how to access it. I assumed it would be part of the completeMultipartUpload response, but I'm not seeing it.
Any help would be appreciated. Thanks!
I found a solution, but it involves an additional request. If anyone knows of a way to access the metadata without making another request, that would be better.
$headObject = $this->client->headObject([
'Bucket' => $this->bucket,
'Key' => $key,
]);
When I download file from s3 bucket, I am using aws-sdk for that, it downloads the files but when i open that file it says It looks like we don't support this file format, here is my full code of it, can anyone please check my code and help me why image is doesn't open the image, my wholde code is in PHP, It looks like small error but doesn't working for me
$bucket = '*****';
$keyname = '1560346461616.jpg';
$s3 = new S3Client([
'version' => 'latest',
'region' => '******',
'credentials' => [
'key' => '******',
'secret' => '******',
],
]);
$result = $s3->getObject([
'Bucket' => $bucket,
'Key' => $keyname,
]);
header("Content-Type: {$result['ContentType']}");
header('Content-Disposition: attachment; filename='.$keyname);
echo $result['Body'];
} catch (Exception $e) {
echo $e->getMessage() . PHP_EOL;
}
Check the content type of your .jpg file stored in s3. Ensure the metadata for this object says image/jpeg.I don't think it is related to the object you downloaded,maybe the download file was corrupted.
When uploading to S3 via PHP SDK even after setting the correct ContentType S3 still shows application/octet-stream
$file = Aws::putObject([
'Bucket' => 'types-jpeg',
'Key' => 'current.jpg',
'SourceFile' => 'uploads/current.jpg',
'ContentType' => 'image/jpeg',
'ACL' => 'public-read',
]);
File successfully uploads except that viewing the file's meta data shows application/octet-stream instead of 'image/jpeg' on its Content-Type
Any ideas?
I can now upload JPG ifrom my BackpackForLaravel to AWS 3 Yahhh!!!
But how or where can i make change this code:
$this->crud->addField([ // image
'label' => "Produkt foto",
'name' => "productfoto",
'type' => 'image',
'tab' => 'Produktfoto',
'upload' => true,
'crop' => true,
'aspect_ratio' => 1,
'disks' => 's3images' // This is not working ??
]);
To showing url from AWS S3 mith my uploaded JPG... (instead of local public)
I can't find any documentation or code examples of it :-(
Please help...
I don't really know how this can be of help to you. Pictures to S3 usually need to be base64 encoded so you will need to decode them before you can store in your s3 bucket. So how i handled it sometime ago is this:
$getId = $request->get('myId');
$encoded_data = $request->get('myphotodata');
$binary_data = base64_decode($encoded_data);
$filename_path = md5(time().uniqid()).".jpg";
$directory = 'uploads';
Storage::disk('s3')->put($directory.'/'.$filename_path , $binary_data);
In summary, i am asuming you have the right permission on your bucket and ready to put in image from your storage disks.
Im trying to get file from s3 bucket using getObject
$s3 = AWS::createClient('s3');
$file = $s3->getObject(array(
'Bucket' => 'hotel4cast',
'Key' => $path->path,
'SaveAs' => public_path()
));
I'm getting below error
Error executing
"GetObject" on "https://s3.amazonaws.com/mybucket/filename.xlsx";
AWS HTTP error: Unable to open /var/www/html/laravel/public/ using mode r+: fopen(/var/www/html/laravel/public/):
ailed to open stream: Is a directory
if i take SaveAs out and dump $file i get object of data, body, stream all that stuff but not sure what to do with that.
I have figured out, there is bug in aws sdk,
i was able to get file to save by storing path in var before calling getObject
$r = fopen(public_path() . '/myfile.xlsx', 'wb');
$s3 = AWS::createClient('s3');
$file = $s3->getObject(array(
'Bucket' => 'bucketname',
'Key' => $path->path,
'SaveAs' => $r
));
can you tell me that what exactly these equals too ? So, I can guide you accordingly.
$path->path = ???
public_path() = ???
Edited
your method params should be like this, you just passing the saveAs path but attaching the key name, So, add the keyname with saveAs path, it will be downloaded.
$s3 = AWS::createClient('s3');
$file = $s3->getObject(array(
'Bucket' => 'hotel4cast',
'Key' => $path->path,
'SaveAs' => public_path()."/filename.xlsx"
));
here are the examples of code, which I am using for uploading file and coping file
for uploading
$result = $this->S3->putObject([
'ACL' => 'public-read-write',
'Bucket' => 'xyz', // REQUIRED
'Key' => 'file.xlsx', // REQUIRED
'SourceFile' => public_path()."/xlsx/file.xlsx",
]);
for Coping from one bucket to another
$copy = $this->S3->copyObject(array(
'ACL' => 'public-read-write',
'Bucket' => 'xyz', // REQUIRED
'Key' => 'file.xlsx', // REQUIRED
'CopySource' => 'mybucketname/xlsx/file.xlsx,
));
but your file which is exists in s3 bucket should have permission to read. other wise it will give you error to saveAs, copy etc
here are multiple permissions, you can see here
'ACL' => 'private|public-read|public-read-write|authenticated-read|aws-exec-read|bucket-owner-read|bucket-owner-full-control',
