Can someone tell me any link or code which I can download file from Azure storage - blob without any SDK and/or multiple files/libraries. It should be like a upload function.
Thanks in advance!
This is the sample that I referred to. It's very detailed and may help you understand using cURL to request API, like Get Blob API.
Request:
GET https://myaccount.blob.core.windows.net/mycontainer/myblob
x-ms-date: Mon, 24 Apr 2021 06:34:09 GMT
x-ms-version: 2014-02-14
Authorization: SharedKey myaccount:<signature_str>
You could refer to this.
<?php
$storageAccount = '';
$containerName = '';
$blobName = '';
$account_key = '';
$date = gmdate('D, d M Y H:i:s \G\M\T');
$version = "2019-12-12";
$stringtosign = "GET\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:". $date . "\nx-ms-version:".$version."\n/".$storageAccount."/".$containerName."/".$blobName;
$signature = 'SharedKey'.' '.$storageAccount.':'.base64_encode(hash_hmac('sha256', $stringtosign, base64_decode($account_key), true));
echo "\n\n" . $signature;
$header = array (
"x-ms-date: " . $date,
"x-ms-version: " . $version,
"Authorization: " . $signature
);
$url="https://$storageAccount.blob.core.windows.net/$containerName/$blobName";
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt ( $ch, CURLOPT_CUSTOMREQUEST, 'GET' );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $header);
curl_exec ( $ch );
$result = curl_exec($ch);
echo "\n\n" . $result;
if(curl_errno($ch)){
throw new Exception(curl_error($ch));
}
file_put_contents('D://demo//downloaded.txt', $result); // save the string to a file
curl_close($ch);
