Unable to download text file through Chunked transfer encoding

Open sergiomartinez4 opened this issue 6 years ago • 14 comments

Issue

1. What problem do you get? I'm not able to download one text file (VTT file). Presumably, it's because the server is using Chunked transfer encoding.

2. Which version of FileDownloader are you using when you produce such problem? Version 1.7.4

3. How to reproduce such problem? Just try downloading the following VTT file. Please note that I added the VTT url to Bitly, because the url expires and I can keep updating it for testing purposes: http://bit.ly/2HtV0gP You might need to get the redirect url first. Please let me know if the url expires.

4. Do you set FileDownloadLog.NEED_LOG=true? Yes

5. Could you please reproduce this problem and provide all main process and :filedownloader process logcat See the logcat below.

6. Can you fix it by yourself and request PR, if not, what's problem do you get when you try to fix it Not at this moment

This is a good issue, thanks.

In fact, the log info has a very clear explanation:

com.liulishuo.filedownloader.exception.FileDownloadGiveUpRetryException: can't know the size of the download file, and its Transfer-Encoding is not Chunked either.
you can ignore such exception by add http.lenient=true to the filedownloader.properties

It means that the server response doesn't contain Content-Length and Transfer-Encoding, so FileDownload doesn't know the file length. Also, you can ignore this issue by adding http.lenient=true to filedownloader.properties, and let me know this solves your problem or not.

@rantianhua thanks for the quick response. Unfortunately, that didn't solve the problem. Here's the new log:

The pivotal log is:

fetched length[9788] != content length[1521], range[0, -1) offset[9788] fetch begin offset[0]

It means that the file length told by server and downloaded by FileDownloader actually are not coincident. It's probably a server's issue. So, I need the log of filedownloader process to find the real problem. If it's not convenient for you to collect the log of filedownloader process, you can add process.non-separate=true into filedownloader.properties so that you can get all log in the main process.

rantianhua avatar Jun 09 '18 04:06 rantianhua

Hi @rantianhua ,

I've added the process.non-separate=true and saved the log. You can find it here: http://bit.ly/2l0cqZM By the way, I'm able to download that VTT file using the web browser or using Android DownloadManager.

Thanks

sergiomartinez4 avatar Jun 11 '18 14:06 sergiomartinez4

I will give you a response tomorrow.

rantianhua avatar Jun 11 '18 14:06 rantianhua

The error message is:

com.liulishuo.filedownloader.exception.FileDownloadGiveUpRetryException: fetched length[9788] != content length[1521], range[0, -1) offset[9788] fetch begin offset[0]

Content-Length is 1521 but FileDownloader get 9788 bytes from the stream.

I get the redirect url from http://bit.ly/2HtV0gP, but it has expired. Could you please give me a useable url so that I can debug it.

rantianhua avatar Jun 12 '18 01:06 rantianhua

@rantianhua sure, here it is: http://bit.ly/2l4U3mA

sergiomartinez4 avatar Jun 12 '18 03:06 sergiomartinez4

@sergiomartinez4 I can sure this is a serve error.

FileDownloader will check the bytes read from stream and returned in the response header, if they are not coincident, FileDownloadGiveUpRetryException will be thrown. In your case, server told FileDownloader that the file size is 1521 bytes, but actually, real size is 9788 bytes. I copied the content downloaded by chrome and saved it in a file, and file size is 9788 bytes too.

2018-06-12 12 27 47

So, FileDownloader did the right action.

You said you can download the file through Chrome and Android DownloadManager, so FileDownloader. What's the difference is that FileDownloader adds a file size check after downloading.

rantianhua avatar Jun 12 '18 04:06 rantianhua

@rantianhua let me check this out and I'll get back to you. Thanks for the info!

sergiomartinez4 avatar Jun 12 '18 21:06 sergiomartinez4

@rantianhua I think one detail is being omitted here. FileDownloader sets Accept-encoding: gzip in the request asdas

To which server responds with Content-Length of gzipped data which is correct behaviour based on RFC 2616.

The file size you're seeing after downloading via Chrome and saving to file is most likely uncompressed. That's probably why you're seeing discrepancy there. That said, if FileDownloader sends Accept-encoding: gzip in the request and expects Content-Length value of uncompressed file, that is, I believe, incorrect behaviour.

I want to download this file https://v.redd.it/b5fdxaieg8y11/HLSPlaylist.m3u8, but get exception com.liulishuo.filedownloader.exception.FileDownloadGiveUpRetryException: fetched length[xxxx] != content length[xxxx], how can i escape this probleam? @rantianhua

You are right. When i try to download this file https://v.redd.it/b5fdxaieg8y11/HLSPlaylist.m3u8 directly, I got FileDownloadGiveUpRetryException: fetched length[xxxx] != content length[xxxx]. After i change the
Accept-encoding to identity , it works well without exception.

怎么解决这个错误呢？fetched length[1140621] != content length[1000887], range[0, -1) offset[1140621] fetch begin offset[0]

799837663 avatar Feb 26 '20 08:02 799837663

FYI: I found a workaround for this issue. I added the "Accept-Encoding" header with the "identity" value when downloading VTT files.

BaseDownloadTask task = FileDownloader.getImpl().create(...);
task.addHeader("Accept-Encoding", "identity");
...

Hope this help anyone else having this problem.
