// 阿里云分片上传
private function multipartUpload($uploadFile,$object){
//第一步 初始化分片上传
$option=['accessKeyId'=>'','accessKeySecret'=>'','endpoint'=>'','bucket'=>''];
$ossClient = new OssClient($option['accessKeyId'], $option['accessKeySecret'], $option['endpoint']);
try{
//返回uploadId。uploadId是分片上传事件的唯一标识，您可以根据uploadId发起相关的操作，如取消分片上传、查询分片上传等。
$uploadId = $ossClient->initiateMultipartUpload($option['bucket'], $object);
} catch(OssException $e) {
$result = $e->getMessage();
}
//第二步 分片上传及设置
$partSize = 2 * 1024 * 1024;//分片文件2m
$uploadFileSize = filesize($uploadFile);
$pieces = $ossClient->generateMultiuploadParts($uploadFileSize, $partSize);
$responseUploadPart = array();
$uploadPosition = 0;
$isCheckMd5 = true;
foreach ($pieces as $i => $piece) {
$fromPos = $uploadPosition + (integer)$piece[$ossClient::OSS_SEEK_TO];
$toPos = (integer)$piece[$ossClient::OSS_LENGTH] + $fromPos - 1;
$upOptions = array(
// 上传文件。
$ossClient::OSS_FILE_UPLOAD => $uploadFile,
// 设置分片号。
$ossClient::OSS_PART_NUM => ($i + 1),
// 指定分片上传起始位置。
$ossClient::OSS_SEEK_TO => $fromPos,
// 指定文件长度。
$ossClient::OSS_LENGTH => $toPos - $fromPos + 1,
// 是否开启MD5校验，true为开启。
$ossClient::OSS_CHECK_MD5 => $isCheckMd5,
);
// 开启MD5校验。
if ($isCheckMd5) {
$contentMd5 = OssUtil::getMd5SumForFile($uploadFile, $fromPos, $toPos);
$upOptions[$ossClient::OSS_CONTENT_MD5] = $contentMd5;
}
try {
// 上传分片。
$responseUploadPart[] = $ossClient->uploadPart($option['bucket'], $object, $uploadId, $upOptions);
} catch(OssException $e) {
$result = $e->getMessage();
}
}
// $uploadParts是由每个分片的ETag和分片号（PartNumber）组成的数组。
$uploadParts = array();
foreach ($responseUploadPart as $i => $eTag) {
$uploadParts[] = array(
'PartNumber' => ($i + 1),
'ETag' => $eTag,
);
}
//第三步 合并分片
try {
// 执行completeMultipartUpload操作时，需要提供所有有效的$uploadParts。OSS收到提交的$uploadParts后，会逐一验证每个分片的有效性。当所有的数据分片验证通过后，OSS将把这些分片组合成一个完整的文件。
$result=$ossClient->completeMultipartUpload($option['bucket'], $object, $uploadId, $uploadParts);
} catch(OssException $e) {
$result = $e->getMessage();
}
return $result;
}
效果图如下：
