URL max lenght

[Jovo Mirkovic]

Is there any limit on the URL length in CN1?

I have a long URL (with image, Base64 converted), and I want call web service and put it in database.

 

When is image enough small, everything is OK, but when is image bigger, I get Error message 414: Request - URl to long.

 

If I put that URL directly to browser, everything is OK... That is reason why I think that is not problem on web server...

 

Thanks,

     Jovo

We don't have a limit but both servers and devices often have a limit frequently its 1024 bytes.
Why not just use post which has bigger limits?

If you want to upload binary data post will fail too (since it still has server/protocol limits), for that we provide the multipart API which has no limits in terms of size (at least in theory).

Thanks Shai.

 

I'll try change cr.setPost(false); to cr.setPost(true);, but it not enough :)
Do you have sample about multipart API...? I want send same text information and few pictures from phone to server, and save it in database...

Make sure your server supports post, it won't work if your server just implements get.
Just replace ConnectionRequest with MultipartRequest (its a subclass so they are pretty compatible). You can then add a binary file instead of Base64 encoding and the multipart aspect will kick in.

Notice that on the server you will have to accept multipart which isn't trivial:
