要实现OSS PHP的断点续传,你可以使用以下步骤:
composer require aliyuncs/oss-php-sdk
require 'vendor/autoload.php';
use OSS\OssClient;
use OSS\Core\Config;
$accessKeyId = 'your-access-key-id';
$accessKeySecret = 'your-access-key-secret';
$region = 'your-region';
$config = new Config();
$config->setRegion($region);
$client = new OssClient($accessKeyId, $accessKeySecret, $config);
putObject
方法上传文件。为了实现断点续传,你需要在上传文件时设置Content-Type
为application/octet-stream
,并且将Content-Disposition
设置为attachment; filename="your-file-name"
。例如:$bucket = 'your-bucket-name';
$filePath = 'path/to/your-local-file';
$objectName = 'your-object-name';
$options = [
' Content-Type' => 'application/octet-stream',
' Content-Disposition' => 'attachment; filename="' . $objectName . '"',
];
$client->putObject($bucket, $objectName, $filePath, null, $options);
function uploadChunk($client, $bucket, $objectName, $filePath, $startOffset, $chunkSize)
{
$file = fopen($filePath, 'r');
fseek($file, $startOffset);
$options = [
' Content-Type' => 'application/octet-stream',
' Content-Disposition' => 'attachment; filename="' . $objectName . '"',
];
$partSize = 5 * 1024 * 1024; // 5MB
$hashTable = [];
for ($i = 0; $i < $chunkSize; $i += $partSize) {
$endOffset = min($startOffset + $chunkSize, filesize($filePath));
fread($file, $partSize); // Read the part
$data = fread($file, $endOffset - $startOffset);
$hash = md5($data);
if (isset($hashTable[$hash])) {
echo "Chunk with hash $hash has already been uploaded.\n";
continue;
}
$result = $client->putObject($bucket, $objectName, $startOffset, $data, $options);
if ($result) {
echo "Chunk with hash $hash uploaded successfully.\n";
$hashTable[$hash] = true;
} else {
echo "Failed to upload chunk with hash $hash.\n";
}
}
fclose($file);
}
$chunkSize = 10 * 1024 * 1024; // 10MB
uploadChunk($client, $bucket, $objectName, $filePath, 0, $chunkSize);
通过这种方式,你可以实现OSS PHP的断点续传功能。
