HttpUrlConnection reading chunked response

Question

I'm working on a project where i have to use HttpUrlConnection (Android~) for reading the input stream.

It turns out that when i'm reading the input stream the data is malformed and has a bigger size from the original content (which is sent by the server). Now, the server response header contains both "Content-Length" and "Transfer-Encoding: chunked", which from what i know is an issue as both of them shouldn't coexist.

Aside from that the input stream received from HttpUrlConnection contains all body content (with chunks offset informations).

I have two questions:

• Shouldn't the HttpUrlConnection handle chunked data?
• How to get the data from input stream without chunked informations?

Answer 1

The HttpUrlConnection should be handling chunked data, you're correct. The fact that you're seeing these headers at all means they're probably being malformed somewhere, and something has already sent either a \n\n or \r\n\r\n, so the HttpUrlConnection views it as part of the actual transmission.

If you WANT to be getting the raw data, use a socket and connect to the url on the correct port (probably 80, 443 for ssl)

EDIT: java.net.URLConnection states under the connect() method

Interact with the resource; query header fields and contents.

This shows that a URLConnection, prior to reading anything in from any sort of provided reader, queries the header information. Pardon me for not including this the first time.
