Requests and responses
Request
Inside any action, the current request is available through the request variable.
The underlying servlet request is implicitly extended with the following methods:
- body
- to get the request body as a string.
- isAjax
- to detect AJAX requests.
- cookies
- a Map view of the request's cookies.
- multiCookies
- a Map view of the request's cookies.
The request also implements a scala.collection.mutable.Map backed by the
request attributes.
The
scalatra-http-demo
is a good place to start if you need to see basic requests and response, cookies,
and dealing with form input.
Response
The response is available through the response variable.
If you override the Scalatra handling and write directly to
the response object (e.g. response.getOutputStream), then your action should
return Unit() to prevent a conflict with multiple writes.
ServletContext
The servlet context is available through the servletContext variable. The
servlet context implicitly implements scala.collection.mutable.Map backed
by servlet context attributes.
