Setup
use HTTP::Server::Async;
use HTTP::Server::Middleware::JSON;
my HTTP::Server::Async $app .=new;
body-parse-json $app;
$app.handler: sub ($req, $res) {
# may or may not have parsed JSON depending on Content-Type
}
$app.handler: $sub ($req, $res) is json-consumer {
# trait<json-consumer>: calls a default or custom error handler for
# invalid JSON found in the body of the request
# if the request gets here then $req.params<body> represents the
# parsed JSON data passed in the request body
}
# this is how to set a custom error handler for invalid or missing JSON
json-error sub ($req, $res) {
#do your thing, the returned value is returned to the underlying HTTP::Server
# so it knows whether or not to continue processing
}
