Steps to Upload File to Huawei OBS (Object Storage Service)

1. Log in to the Huawei Cloud Management Console and navigate to the OBS Service page.
2. Create a bucket, which is a container for storing your data.
3. Click the bucket to open it and then select “Upload Files”.
4. Select the file you want to upload and click “Open” to start the upload process.

Sample PHP Script to upload Files to Huawei OBS (Object Storage Service)

<?php

// replace with your OBS access key and secret key
$accessKey = "YOUR_ACCESS_KEY";
$secretKey = "YOUR_SECRET_KEY";

// replace with your OBS endpoint and bucket name
$endpoint = "https://obs.cn-north-1.myhuaweicloud.com";
$bucket = "YOUR_BUCKET_NAME";

// replace with the path to your file
$filePath = "path/to/your/file.txt";

// create a request for the PUT object operation
$url = "$endpoint/$bucket/".basename($filePath);
$contentType = mime_content_type($filePath);
$date = gmdate('D, d M Y H:i:s T');
$signature = base64_encode(hash_hmac('sha1', "PUT\n\n$contentType\n$date\n/$bucket/".basename($filePath), $secretKey, true));

// upload the file
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    "Content-Type: $contentType",
    "Authorization: AWS $accessKey:$signature",
    "Date: $date",
]);
curl_setopt($ch, CURLOPT_INFILE, fopen($filePath, 'rb'));
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($filePath));
$response = curl_exec($ch);
curl_close($ch);

// check the response for success or failure
if ($response === false) {
    die("Failed to upload file: ".curl_error($ch));
} else if (substr($response, 0, 4) != "HTTP") {
    die("Failed to upload file: Unexpected response");
} else if (strpos($response, "200 OK") === false) {
    die("Failed to upload file: ".substr($response, 0, strpos($response, "\r\n")));
}

echo "File uploaded successfully";
