AWS OVH (aws/aws-autoloader) - php

Question

I can connect to my ovh storage:
$s3Client = new S3Client(['profile' => 'default','endpoint' =>'http://storage.sbg.cloud.ovh.net', 'region' => 'SBG','version' => latest','credentials' => array('key' => $key,'secret' => $secret,)]);
and list all my containers
$result = $s3Client->listBuckets();var_dump($result);)
But I cannot create a new one:
$s3Client->createBucket(array('Bucket' => 'cont1',));
=> So I reate it on OVH web interface :swift,SBG,private,cont1.
When I would like to upload a file in this new container :
$result = $s3Client->upload('cont1', 'test.123', fopen($file_name, 'rb'), 'public-read');
I get :
PHP Fatal error: Uncaught exception 'Aws\\S3\\Exception\\S3Exception' with message 'Error executing "PutObject" on "http://moncontainer.storage.sbg.cloud.ovh.net/test.zip";
AWS HTTP error: Client error: `PUT http://moncontainer.storage.sbg.cloud.ovh.net/test.zip` resulted in a `400 Bad Request` response:\n\nMalformedXMLThe XML you provided was not well-formed (truncated...)\n MalformedXML (client): The XML you provided was not well-formed or did not validate against our published schema - \nMalformedXMLThe XML you provided was not well-formed or did not validate against our published schematx7bd76ec0ba114f32951bb-0061d553da'\n\nGuzzleHttp\\Exception\\ClientException: Client error: `PUT http://moncontainer.storage.sbg.cloud.ovh.net/test.zip` resulted in a `400 Bad Request` response:\n\nMalformedXMLThe in /home/SrvWeb/BackupOVH/Proc/JSR/aws/Aws/WrappedHttpHandler.php on line 195
but if I put 'cont1/' (with slash)
$result = $s3Client->upload('cont1/', 'test.123', fopen($file_name, 'rb'), 'public-read');
an object is created in 'cont1' but named '/test.123'
What is the good way to create a container and how to upload a file with the correct name ?

Answer 1

Good news... part of the answer :
To push a file in a container with the good filename :
$containername = 'moncontainer';
$result = $s3Client->upload($containername, $containername.'/'.basename($file_Path), fopen($file_Path, 'rb'), 'public-read');
Still investigating for the creation of the container :(
