I've been +using it with a fait amount of success and I'm a fairly new Erlang +developer. I'm mainly interested in the REST "interface" of the application +and its way of doing RESTful things, and I like the way you did it (what +with all the content_types_provided, service_available, etc. functions). +I've tested the way the system reacted to the different Accept, +Content-Type, etc. headers and always got very well-opinionated responses +(406, 415, ...). + +A couple of questions remain though (I'm sorry if they've been asked +already but I've searched the web for answers and read the available docs +and couldn't find them): + +1. is it expected that, if I use cowboy_req:reply/2 in a GET handler +(coming from content_types_provided), the onresponse/4 hook be called +twice? I guess one is due to the reply and the other one due to the +workflow of the request, but is there a way to prevent the second execution? + +2. if I want to JSON-parse ALL my requests should I a) use the onrequest/1 +hook or b) do this on a per-request basis? Because I'd like to reply with a +400 ASAP but keep going if the JSON validates (I'm going to use JSON-schema +for validating input); and, if possible, have the JSON-parsed body stored +somewhere for future manipulation. + +3. I haven't seen examples that made use of the State (from the function +returns). When should I use this instead of the Request metadata? I'd like +to be able to set a generic error state for a request (either in meta ou +State) and that have a "standard" error response be created at a later time +(in a unique function, for example - e.g. onresponse/4). + +4. is there anything like a catch-all exception handler? I'd like to catch +exceptions that occur anywhere so I could log them and analyze them at a +later moment. + +I'm probably abusing the onresponse/onrequest hooks already, so your +answers should help me clarify this. + +Thanks. + +- Paulo +-------------- next part -------------- +An HTML attachment was scrubbed... +URL: <<A HREF="http://lists.ninenines.eu/archives/extend/attachments/20140520/cf7632e9/attachment.html">http://lists.ninenines.eu/archives/extend/attachments/20140520/cf7632e9/attachment.html</A>> +</PRE> + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="000383.html">[99s-extend] Gracefully stop Ranch +</A></li> + <LI>Next message: <A HREF="000386.html">[99s-extend] REST responses +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#384">[ date ]</a> + <a href="thread.html#384">[ thread ]</a> + <a href="subject.html#384">[ subject ]</a> + <a href="author.html#384">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://lists.ninenines.eu/listinfo/extend">More information about the Extend +mailing list</a><br> +</body></html> |
