public interface SlingHttpServletRequest
The SlingHttpServletRequest
defines the interface to provide
client request information to a servlet.
Request Parameters Generally request parameters are transmitted as
part of the URL string such as GET /some/path?param=value
or as request data of content type application/x-www-form-urlencoded
or multipart/form-data. The Sling Framework must decode parameters
transferred as request data and make them available through the various
parameter accessor methods. Generally parameters transferred as
multipart/form-data will be accessed by one of the methods returning
RequestParameter
instances.
In any case, the ServletRequest.getReader()
and ServletRequest.getInputStream()
methods
will throw an IllegalStateException
if called after any methods
returning request parameters if the request content type is either
application/x-www-form-urlencoded or multipart/form-data
because the request data has already been processed.
Starting with Sling API 2.0.6, this interface als extends the
Adaptable
interface.

object on whose behalf the servlet acts.
Resource
object of this request.ResourceResolver getResourceResolver()
ResourceResolver
which resolved the
resource
of this request.
RequestPathInfo getRequestPathInfo()
RequestPathInfo
pertaining to this request.
RequestParameter getRequestParameter(String name)
RequestParameter
,
or null
if the parameter does not exist.
This method should only be used if the parameter has only one value. If
the parameter might have more than one value, use
getRequestParameters(String)
.
If this method is used with a multivalued parameter, the value returned
is equal to the first value in the array returned by
getRequestParameters
.
This method is a shortcut for
getRequestParameterMap().getValue(String)
.
name
- a String
specifying the name of the parameter
RequestParameter
representing the single value of the
parameter
IllegalArgumentException
- if name is null
.getRequestParameters(String)
,
RequestParameterMap.getValue(String)
RequestParameter[] getRequestParameters(String name)
RequestParameter
objects containing all of
the values the given request parameter has, or null
if the
parameter does not exist.
If the parameter has a single value, the array has a length of 1.
This method is a shortcut for
getRequestParameterMap().getValues(String)
.
name
- a String
containing the name of the parameter
the value of which is requested
RequestParameter
objects containing the
parameter values.
IllegalArgumentException
- if name is null
.getRequestParameter(String)
,
RequestParameterMap.getValues(String)
RequestParameterMap getRequestParameterMap()
Map
of the parameters of this request.
The values in the returned Map
are from type
RequestParameter
array (RequestParameter[]
).
If no parameters exist this method returns an empty Map
.
Map
containing parameter names as
keys and parameter values as map values, or an empty
Map
if no parameters exist. The keys in the
parameter map are of type String. The values in the parameter map
are of type RequestParameter
array (RequestParameter[]
).javax.servlet.RequestDispatcher getRequestDispatcher(String path, RequestDispatcherOptions options)
RequestDispatcher
object that acts as a wrapper
for the resource located at the given path. A
RequestDispatcher
object can be used to include the
resource in a response.
Returns null
if a RequestDispatcher
cannot
be returned for any reason.
