Pyjamas txJSON-RPC examples may be broken

[Duncan McGreggor]

Terry Jones reported that he couldn't get the pyjamas txSJON-RPC examples to work. If this is a problem with the txJSON-RPC lib, it needs to be fixed. If it's a problem with the pyjamas examples, that needs to be communicated to upstream.

Here are some notes from Terry in an IRC chat:

[09:10] <terrycojones> i tried the pyjamas book example, followed it closely, but doesn't want to work for me. i get:
[09:10] <terrycojones> Method Not Allowed
[09:10] <terrycojones> The requested method POST is not supported by /output/test_slide.txt.
[09:10] <terrycojones> 405
[09:17] <terrycojones> their code: HTTPRequest().asyncPost("test_slide.txt", "", SlideLoader(self))
[09:17] <terrycojones> looks wrong. seems like that should be "/test".

I verified that hitting the twisted.web2 server with

$ curl -d '{"params":["blahblah"],"method":"echo"}' http://localhost:7080/test/

was working. (Note that this is twisted.web2 since that's the example used in the Pyjamas book.)

The book example isn't very clear about what you're supposed to do. I used
root = static.File(".")
and ran twistd in that same dir (the one that contains the output directory after running
pyjsbuild Slideshow.py. Then visit http://localhost:7080/output/Slideshow.html in your browser.

At least according to http://pyjs.org/book/output/Bookreader.html#Rest%20of%20the%20World
you should have root.putChild("test", Example()) in your server.tac file, which is what led
me to comment that the line in the example with HTTPRequest().asyncPost("test_slide.txt"
seems wrong (try it, you'll see an error about not being able to POST to /test_slide.txt)
so I tried with "/test" which produces the text of the Twistd server's echo call
(i.e., the call is made, and the returned JSON is simply displayed in the browser - which
is to say that it looks nothing like a slideshow :-))

And at that point I stopped...
