Acorn URI_Dispatch

Hi. First post here, so I hope it is in the right place.

I am trying to use the AcornURI module (version 0.22 14-Jan-2012) included in the Raspberry Pi Alpha build to send off a URI request to a webserver on a another computer.

I want to do this with my own software without using a conventional browser and reading the Acorn URI Handler Functional Description tells me that I should be able to do so.

But I can not make it work and can’t find any examples on the Internet.

When my task issues the URI_Dispatch SWI, I get two messages back from the URI module (URI_Mprocess and URI_MReturnResult) indicating that the URI was claimed for processing, but the webserver logs do not show the request arriving.

Does anybody have any examples of the code I need to use (preferably in BASIC) to get this working?

Have you checked that URI_MReturnResult is actually returning a succesful result (bit 0 of flags at messageblock+20 = 0)?

You can find an example program by John-Mark Bell (of NetSurf fame) here

Yes, Thanks. I can see that URI_MReturnResult is returning a success flag.

I have looked at the example program and it just causes NetSurf to be fired up. (I could do that).

What I want is for the request to be sent to the webserver without firing up NetSurf. (In effect, I wany my program to behave as if it is a web browser and just swallow up the returned web page.

I am not interested in seeing the webpage, but I do want the webserver to run the CGI script, so it deals with the message I am trying to sent it.

That’s not what AcornURI does. URI_Dispatch is used by applications which can’t handle Internet access to delegate the task to applications which can (say, NetSurf). It’s the module which enables you to double-click a URL in StrongED to launch it in a browser, and if you have Messenger Pro, that has a similar function for making URLs in plain text emails clickable.

It is NOT a web browser, it’s a middleman between your program and an actual web browser.

Maybe try wget?

OK – Thanks for that.

I have tried wget – but the versions I have tried do not work on the Raspberry Pi.

I just get an error message – “No writeable memory at this address”.

Try increasing the wimpslot.

Excellent :)

Thank you all – that works a treat. It also works on VRPC as well.

Problem solved. And so easy to use. :)
