Hi All,
I spent a few hours last night trying to hook a HaXR XML-RPC server up with WAI instead of using the built-in CGI support. Alas, I failed dismally. Is there any more thorough tutorial-style documentation for WAI? Or a good example project that does something more sophisticated than "Hello, Web!"?
What tripped me up was trying to figure out the enumerator part of the API so that I can read the request body (and turn it into a String) and run the XML-RPC request handler. Any help would be appreciated!
There's no tutorial on WAI at the moment. You could look at the code in yesod-core to get an idea of how to use it, but I doubt that will give you much of a return on your investment. In the future, I intend to add a nice explanation of WAI to the Yesod book, but I'm not there yet. As for your specific issue: if you don't mind reading the entire request body into memory, you can get a lazy bytestring fairly easily using the consume[1] function from the enumerator package. Converting that into a String depends on your character encoding. If you're looking to do *lazy* IO... that's a bit more complicated, and will necessarily involve some hacks, but it is possible. I'll likely be writing that kind of code in the not-too-distant future, so let me know if you're interested in that. Also, if you can think of specific examples you would like to see, let me know and I can try to add them to the repo.
