AWS PHP SDK Version 2 S3 putObject Error - php

So the AWS php sdk 2.x library has been put out recently and I've taken a turkey day plunge into upgrading from 1.5x. My first was to upgrade my S3 backup class. I've quickly run into an error:
Fatal error: Class 'EntityBody' not found in /usr/share/php/....my file here
when trying to upload a zipped file to an S3 bucket. I wrote a class to abstract the writing a bit to allow for multi-region backup, so the code below references to $this are that.
$response1 = $s3->create_object(
$this->bucket_standard,
$this->filename,
array(
'fileUpload' => $this->filename,
'encryption' => 'AES256',
//'acl' => AmazonS3::ACL_PRIVATE,
'contentType' => 'text/plain',
'storage' => AmazonS3::STORAGE_REDUCED,
'headers' => array( // raw headers
'Cache-Control' => 'max-age',
//'Content-Encoding' => 'gzip',
'Content-Language' => 'en-US'
//'Expires' => 'Thu, 01 Nov 2012 16:00:00 GMT'
),
'meta' => array(
'param1' => $this->backupDateTime->format('Y-m-d H:i:s'), // put some info on the file in meta tags
'param2' => $this->hostOrigin
)
)
);
The above worked fine on 1.5.x.
Now, in 2.x, I'm looking into their docs and they've changed just about everything (great...maximum sarcasm)
$s3opts=array('key'=> $this->accessKey, 'secret' => $this->secretKey,'region' => 'us-east-1');
$s3 = Aws\S3\S3Client::factory($s3opts);
so now I've got a new S3 object. And here is my 2.x syntax to do the same exact thing. My problem arises where they've (sinisterly) changed the old "fileupload" to "Body" and made it more abstract in how to actually attach a file! I've tried both and I'm thinking it has to do with the dependencies (Guzzle or Smyfony etc), but I get the error above (or substitute Stream if you like) whenever I try to execute this.
I've tried using Composer with composer.json, and the aws.phar but before I get into that, is there something dumb I'm missing?
$response1 = $s3->putObject(array(
'Bucket' => $this->bucket_standard,
'Key' => $this->filename,
'ServerSideEncryption' => 'AES256',
'StorageClass' => 'REDUCED_REDUNDANCY',
'Body' => EntityBody::factory(fopen($this->filename, 'r')),
//'Body' => new Stream(fopen($fullPath, 'r')),
'MetaData' => array(
'BackupTime' => $this->backupDateTime->format('Y-m-d H:i:s'), // put some info on the file in meta tags
'HostOrigin' => $this->hostOrigin
)
));
Thanks as always,
R

Did you import the EntityBody into your namespace?
use Guzzle\Http\EntityBody;
Otherwise, you'd have to do
'Body' => \Guzzle\Http\EntityBody::factory(fopen($this->filename, 'r')),

Amazon Polly AudioStream is always empty

I am trying to get Polly to read something for me, using PHP.
I have created a new project, installed Amazon composer require aws/aws-sdk-php and then created a file with code from SDK documentation example and modified a few minor things such as changing credential from default to value, var_dump to var_export and finally saved the content of the stream to file
<?php
require 'vendor/autoload.php';
use Aws\Exception\AwsException;
use Aws\Polly\PollyClient;
use Aws\Credentials\Credentials;
// Create a PollyClient
$client = new Aws\Polly\PollyClient([
//'profile' => 'default',
'credentials' => new Credentials('XXXXXXXXXXXXXXXXXXXX', 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'),
'version' => '2016-06-10',
'region' => 'us-east-2'
]);
try {
$result = $client->synthesizeSpeech([
'Text' => 'Hello',
'OutputFormat' => 'json', //json|mp3|ogg_vorbis|pcm
'VoiceId' => 'Joanna',
]);
var_export($result);
$data = $result->get('AudioStream')->getContents();
echo "\n\n";
var_export($data);
$file = fopen('test.txt','w+');
fwrite($file,$data);
fclose($file);
} catch (AwsException $e) {
echo $e->getMessage() . "\n";
}
The result I'm getting is following
Aws\Result::__set_state(array(
'data' => array (
'AudioStream' => GuzzleHttp\Psr7\Stream::__set_state(array(
'stream' => NULL,
'size' => NULL,
'seekable' => true,
'readable' => true,
'writable' => true,
'uri' => 'php://temp',
'customMetadata' => array (),
)),
'ContentType' => 'application/x-json-stream',
'RequestCharacters' => '5',
'#metadata' => array (
'statusCode' => 200,
'effectiveUri' => 'https://polly.us-east-2.amazonaws.com/v1/speech',
'headers' => array (
'x-amzn-requestid' => 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX',
'x-amzn-requestcharacters' => '5',
'content-type' => 'application/x-json-stream',
'transfer-encoding' => 'chunked',
'date' => 'Sat, 18 Sep 2021 05:11:20 GMT',
),
'transferStats' => array (
'http' => array (
0 => array (),
),
),
),
),
'monitoringEvents' => array (),
))
''
As you can see the size of the AudioStream is null (nothing in it) and also the created file is also empty since there is nothing in the stream to read.
If I change a credential to an invalid string, I get errors, and with the valid credential, the status code is 200, which makes me believe that my request is successful.
I changed voiceId to any other valid or invalid id and even changed the region with others with valid values getting status 200 and with invalid ones getting error messages, but I'm still not getting anything out of polly, it doesn't feel like talking!
Note: When I run $arr_voices = $polly->describeVoices();, I can read list of the voices without error.
Note: I had the same issue with .NET SDK too, which makes me think either there is something wrong with my request or some error message is missing from API.
Question
What I'm doing wrong?
You're not doing anything wrong, but it only outputs JSON if you're looking for speech marks. Try switching to an audio output format like MP3 as shown below.
$result = $client->synthesizeSpeech([
'Text' => 'Hello',
'OutputFormat' => 'mp3', //json|mp3|ogg_vorbis|pcm
'VoiceId' => 'Joanna',
]);
If you're looking for speech marks- metadata on the speech that will be synthesized- you need to specify SpeechMarkTypes as shown here https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-polly-2016-06-10.html#synthesizespeech

How do I upload a gzip object to s3?

I am creating a gzip string and uploading it as an object to s3. However when I download the same file from s3 and decompress it locally with gunzip I get this error: gunzip: 111.gz: not in gzip format When I look at the mime_content_type returned in the file downloaded from s3 it is set as: application/zlib
Here is the code I am running to generate the gzip file and push it to s3:
for($i=0;$i<=100;$i++) {
$content .= $i . "\n";
}
$result = $this->s3->putObject(array(
'Bucket' => 'my-bucket-name',
'Key' => '111.gz',
'Body' => gzcompress($content),
'ACL' => 'authenticated-read',
'Metadata' => [
'ContentType' => 'text/plain',
'ContentEncoding' => 'gzip'
]
));
The strange thing is that if I view the gzip content locally before I send it to s3 I am able to decompress it and see the original string. So I must be uploading the file incorrectly, any thoughts?
According to http://docs.aws.amazon.com/aws-sdk-php/v3/api/api-s3-2006-03-01.html#putobject the ContentType and ContentEncoding parameters belong on top level, and not under Metadata. So your call should look like:
$result = $this->s3->putObject(array(
'Bucket' => 'my-bucket-name',
'Key' => '111.gz',
'Body' => gzencode($content),
'ACL' => 'authenticated-read',
'ContentType' => 'text/plain',
'ContentEncoding' => 'gzip'
));
Also it's possible that by setting ContentType to text/plain your file might be truncated whenever a null-byte occurs. I would try with'application/gzip' if you still have problems unzipping the file.
I had a very similar issue, and the only way to make it work for our file was with a code like this (slightly changed according to your example):
$this->s3->putObject(array(
'Bucket' => 'my-bucket-name',
'Key' => '111.gz',
'Body' => gzcompress($content, 9, ZLIB_ENCODING_GZIP),
'ACL' => 'public-read',
'ContentType' => 'text/javascript',
'ContentEncoding' => 'gzip'
));
The relevant part being gzcompress($content, 9, ZLIB_ENCODING_GZIP), as AWS S3 wouldn't recognize the file nor serve it in the right format without the last ZLIB_ENCODING_GZIP parameter.

AWS Lambda PHP Create Function with Zip

I'm trying to create a PHP script that creates a function from some code that i zip up on our server. I uploaded the file manually to lambda, and it works fine. But when i try to use the aws sdk to create the function, it fails with an error message. Anyone got any clue?
Code:
private function createLambdaFunction() {
$result = $this->lambdaConn->createFunction(array(
'FunctionName' => $this->lambdaFunctionName,
'Runtime' => $this->runtime,
'Role' => $this->role,
'Handler' => $this->lambdaFunctionName.".".$this->handler,
'Description' => $this->description,
'Timeout' => $this->timeout,
'MemorySize' => $this->memorySize,
'Code' => array(
'ZipFile' => 'fileb://test.zip'
)
));
Error:
PHP Fatal error: Uncaught Aws\Lambda\Exception\LambdaException: AWS
Error Code: InvalidParameterValueException,
Status Code: 400, AWS Request ID: asdf, AWS Error Type: user,
AWS Error Message: Could not unzip uploaded file. Please check
your file, then try to upload again., User-Agent:
aws-sdk-php2/2.8.10 Guzzle/3.9.3 curl/7.35.0 PHP/5.5.9-1ubuntu4.9
I can't seem to find a good example on google, and the documentation is...less than ideal. I created the zip file with php, so I've tried passing that var, the full path to the file, relative path to file, etc. Finally learned you have to use fileb:// preface, but that didn't end up fixing anything.
Okay, I'm not sure why this is the case, but you need to base64 encode your zip file like:
$result = $this->lambdaConn->createFunction(array(
'FunctionName' => $this->lambdaFunctionName,
'Runtime' => $this->runtime,
'Role' => $this->role,
'Handler' => $this->lambdaFunctionName . "." . $this->handler,
'Description' => $this->description,
'Timeout' => $this->timeout,
'MemorySize' => $this->memorySize,
'Code' => array(
'ZipFile' => 'fileb://'.base64_encode(file_get_contents('test.zip'))
)
));
I'm not sure why this is required, as accourding to the doumentation and a post by an AWS employee, you dont have to have base64 encoding for create function. They must have mixed up something or another.

Set Cache-Control HTTP Header for S3 Objects from PHP AWS SDK

I using the Amazon SDK for PHP and trying to set Cache-control Header on the image. When I try to add it via MetaData = array("Cache-Control") it changes it to be x-amz-meta-cache-control when I login to the S3 bucket, and when I download the file, there is no Cache-control set. But if I manually change this setting, the Cache-control works perfectly. Is there some parameter I missing that I can use to set HTTP Request Headers programmatically on upload? I'm using the PutObject method. I believe the AWS SDK is from 2013.
The cache control isn't set via the "MetaData" index, "CacheControl" is at the same level as "MetaData", not contained within it.
http://docs.aws.amazon.com/aws-sdk-php-2/latest/class-Aws.S3.S3Client.html#_putObject
You'd use something like this as your configuration array for the putObject() method...
$s3client->putObject(array(
'Bucket' => '...',
'key' => '...',
'body' => '...',
'CacheControl' => 'max-age=172800',
'MetaData' => array(
'metaKey' => 'metaValue',
'metaKey' => 'metaValue'
)));
For the upload() method...
$s3client->upload(
'bucket',
'key',
fopen('sourcefile','r'),
'public-read',
array('params' => array(
'CacheControl' => 'max-age=172800',
'Metadata' => array(
'metaKey' => 'metaValue',
'metaKey' => 'metaValue'
))));
Also, it's worth pointing out that upload() will wrap putObject() for files of 5MB in size, otherwise it will initiate a multipart upload request.
If you want to add the CacheControl header to an item already in your bucket, use the SDK's copyObject method. Set the MetadataDirective param to REPLACE to make the item overwrite itself.
I noticed one weird thing: I had to set the ContentType header too, even though it was already set. Otherwise the image would not display inline in the browser but be offered as a download.
$result = $s3->copyObject(array(
'ACL' => 'public-read',
'Bucket' => $bucket, // target bucket
'CacheControl' => 'public, max-age=86400',
'ContentType' => 'image/jpeg', // !!
'CopySource' => urlencode($bucket . '/' . $key),
'Key' => $key, // target file name
'MetadataDirective' => 'REPLACE'
));

How do i update object using php-sdk? (The parameter object is required)

$response = $facebook->api(
'me/objects/namespace:result',
'POST',
array(
'app_id' => app_id,
'type' => "namespace:result",
'url' => "http://samples.ogp.me/370740823026684",
'title' => "Sample Result",
'image' => "https://fbstatic-a.akamaihd.net/images/devsite/attachment_blank.png",
'description' => ""
)
);
I get the following error.
The parameter object is required
I don't know where to add the parameter object.
I have been facing the same issue for the past couple of days, in the end I stopped trying to use the Facebook PHP SDK to send the request and resorted to using just sending a HTTP Request.
I am creating an object rather than updating one, but the implementation shouldn't differ much from your needs. I was getting the same error (The parameter object is required) and the below implementation resolved that issue.
I used the vinelab HTTP client composer package and built a request like this:
$request = [
'url' => 'https://graph.facebook.com/me/objects/namespace:object',
'params' => [
'access_token' => $fbAccessToken,
'method' => 'POST',
'object' => json_encode([
'fb:app_id' => 1234567890,
'og:url' => 'http://samples.ogp.me/1234567890',
'og:title' => 'Sample Object',
'og:image' => 'https://fbstatic-a.akamaihd.net/images/devsite/attachment_blank.png',
'og:description' => 'Sample Object'
])
]
];
// I'm using Laravel so this bit might look different for you (check the vine lab docs if you use that specific HTTP client)
$response = HttpClient::post($request);
// raw content
$response->content();
// json
$response->json();
As I said, I used the vinelab HTTP package in my implementation, you should be able to use any similar package or directly use curl in PHP instead.
