我們有一個網站可以將文件傳輸給我們的客戶。現在,我們開始使用大於300Mb的文件,並且沒有明顯的原因,下載內容隨機失敗。我們收到「下載被中斷」錯誤。文件下載在IIS中隨機失敗PHP
我們登錄到服務器,發現PHP進程有時會在下載開始時關閉,但事件查看器或日誌中沒有任何重要的內容。
下面是提供的下載代碼:
public function downloadAction($asset, $csrfToken) {
if ($this->securityContext->isCsrfProtectionTokenValid($csrfToken) === FALSE) {
throw new \TYPO3\Flow\Security\Exception\AccessDeniedException();
}
// This is a : \TYPO3\Flow\Resource\Resource
$resource = $asset->getResource();
$stream = $resource->getStream();
if (FALSE === $stream) {
$this->throwStatus(500);
}
try {
$streamMetadata = stream_get_meta_data($stream);
$modified = filemtime($streamMetadata['uri']);
$filename = $asset->getResource()->getFilename();
$this->response->setStatus(200);
$this->response->setHeader('Content-Type', 'application/octet-stream');
$this->response->setHeader('Content-Disposition', 'attachment; filename="' . $filename . '"');
$this->response->setHeader('Last-Modified', gmdate('r', $modified));
$this->response->setHeader('Content-Length', $asset->getResource()->getFileSize());
$this->response->setHeader('Content-transfer-encoding', 'binary');
$this->response->sendHeaders();
@set_time_limit(86400);
$fileBuffer = 8192;
while (!feof($stream)) {
print(fread($stream, $fileBuffer));
ob_flush();
flush();
}
} finally {
fclose($stream);
}
return '';
}
這裏是我們的設置:
- 的Windows Server 2008 R2
- IIS 7.5
- PHP 30年5月5日
我的嘗試:
我試圖增加memory_limit的到1024MB,增加超時,增加了腳本的執行時間,我們沒有從提高這些得到任何好處。
從事件查看器,我們得到了很多的錯誤,當下載失敗:

它看起來像修改,以12000個工作緩衝區的投入,但而不是11999.這是什麼樣的魔法?
我試圖做到這一點,但仍然有同樣的錯誤。這讓我想知道它可能是一個IIS配置問題... – CoachNono
