ERR_CONTENT_LENGTH_MISMATCH 在 chrome 中加载视频时

ERR_CONTENT_LENGTH_MISMATCH when loading video in chrome

所以我在播放某些视频时遇到此错误。当 Chrome 完全下载视频时,它停止播放并出现此错误。此外,请求的状态从 206 更改为(失败),然后 Chrome 发送一些其他带有 Range:bytes=2990775- 的请求,服务器响应为:

Accept-Ranges:bytes
Cache-Control:private
Connection:keep-alive
Content-Disposition:attachment; filename="About The Author.mp4"
Content-Length:0
Content-Range:bytes 2990775-2990775/2990776
Content-Transfer-Encoding:binary
Content-Type:video/mp4

我在同一台服务器上还有另一个网站,在那里工作正常。

这是我的 PHP 代码:

        $filesize = filesize($resource->path);

        $matches = explode("-", substr($_SERVER['HTTP_RANGE'],6));
        if (empty($matches[1]))
        {
            $matches[1] = $filesize - 1;
        }

        $offset = intval($matches[0]);
        $length = intval($matches[1]) - $offset;

        $file = fopen($resource->path, 'r');

        fseek($file, $offset);

        $data = fread($file, $length);
        fclose($file);

        header('HTTP/1.1 206 Partial Content');
        header('Content-Range: bytes ' . $offset . '-' . ($offset + $length) . '/' . $filesize);

        header('Pragma: public');   
        header('Last-Modified: '.gmdate ('D, d M Y H:i:s', filemtime ($resource->path)).' GMT');
        header('Cache-Control: private',false);
        header('Content-Type: ' . $mime);
        header('Content-Length: ' . ($length + 1));
        header('Content-Disposition: attachment; filename="' . $resource->filename . '"');
        header('Content-Transfer-Encoding: binary');
        header('Accept-Ranges: bytes');

        print($data);

抱歉我的英语不好。

我找到问题了。

我把$data = fread($file, $length);改成了$data = fread($file, $length + 1);

我不知道为什么请求的长度应该加一,但它解决了问题。
