php – 在Chrome中加载视频时的ERR_CONTENT_LENGTH_MISMATCH

因此,当某些视频播放时,我会收到此错误消息.当Chrome完全下载视频时,它会停止播放此错误.此外,请求的状态从206更改为(失败),然后Chrome发送一些其他请求,范围：bytes = 2990775-,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有另一个网站,它在那里工作正常.

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);

对不起,我的英语不好.

解决方法:

我发现了这个问题.

我更改了$data = fread($file,$length); $data = fread($file,$length 1);.

我不知道为什么要求的长度应加一,但它解决了问题.
