how to get chunked data in a webrequest

[cool_zephyr]

hello everyone..i'm trying to get a file in a server using a WebRequest..the server sends some headers saying "Transfer-Encoding :chunked"..what does this basically mean??? I'm using a BinaryReader to read the data..but after some few hundred bytes the transfer just stops..do i have to make a WebRequest again to get the remaining portion of the file??? Please help.

Try this:
http://blog.degree.no/2011/06/webclient-httpwebresponse-problems-with-chunked-transfer-encoding/

... which says:

The easiest way to fix this is to make sure the HttpWebRequest is sent using HTTP 1.0 - this way the server will reply with a HTTP Header specifying Content-Length.

HttpWebRequest wr = (HttpWebRequest)WebRequest.Create("http://www.degree.no");
wr.ProtocolVersion = Version.Parse("1.0");

hey thanks for reply..it works this way..one more question, if the server uses UTF-8 encoding,does it apply to the binary data in file transfer too or just the text type??

[thines01]

...not sure. Is your download coming to you with the wrong encoding?

[cool_zephyr]

yeah i get the HTML code..then the transfer stops..but the data i want to retrieve is a stream audio..and I don't know how to access it..could you tell me how to do that??

[thines01]

Did you open a stream?

like:

protected static Stream GetRepsonseStream(string strURI)
      {
         HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(strURI);
         req.ProtocolVersion = HttpVersion.Version10;
         return req.GetResponse().GetResponseStream();
      }

Also, if you did, I saw this post on keeping the sample rate low

[cool_zephyr]

yeah and after getting the stream..i'm using a binaryreader to read the stream..

BinaryReader reader = new BinaryReader(dataStream);
            
byte[] b = new byte[999999];
int index = 0;        
while ((reader.Read(b, index, 2000)) != 0)
{                
    index += 2000;              
}

my confusion is that..the server is sending HTML codes n stopping the transfer..how do i get an audio stream?? (suppose i'm playing a streaming mp3 file)

[thines01]

Right. Do you have a URI to the actual stream?

[cool_zephyr]

yeah

[thines01]

What happens if you just use the stream and not the BinaryReader?

[cool_zephyr]

if just retrieves the HTML page n stops the transfer

[thines01]

Do you have a public page with this kind of stream on it where I can try something?

[cool_zephyr]

http://loudwire.com/iced-earth-vs-lamb-of-god-death-match/
try this

[thines01]

OK. There is LOTS of content on that page.
Which piece are you trying to get?

[cool_zephyr]

well the first video or the 2nd one..anything does just need to know how to do this

[thines01]

That is a completely different problem.
Those are YouTube videos and require different handling altogether.

You can harvest some code from this YouTube Downloader on codeplex or you can get a utility like CucuSoft YouTube Mate if you just want the video without coding.
