At the risk of promoting my own tool, I created a tool (in Clojure and
ClojureScript) to debug just this sort of problem. It's called: POSThere.io (
https://github.com/SnootyMonkey/posthere.io )
Point your cURL command at POSTHere.io (you make up whatever URL you want, so I
just used the same one you were using, /todo/todos/delete):
curl -H "Content-Type: application/json" -X POST -d "{\"id\":1}"
http://posthere.io/todo/todos/delete
And update your CLJS code to use POSTHere.io:
(ajax/POST "http://posthere.io/todo/todos/delete";
{:format :json
:response-format :json
:handler #(dispatch [:handle-del-resp %1])
:error-handler #(dispatch [:handle-error %1])
:params {"id" id}})
Then visit that POSThere.io URL: http://posthere.io/todo/todos/delete
It'll show all the details about your two posts and you can see exactly how
they differ.
Cheers,
Sean
