Common scripting variables
The basic objects, such as the request and response, are available for all scripting languages.
| Name |
Description |
| request |
SlingHttpServletRequest![]() object, providing access to the HTTP request header information - extends the standard HttpServletRequest![]() - but also to Sling-specific things like resource, selectors, etc. |
| response |
SlingHttpServletResponse![]() object, providing access for the HTTP response that is created by the server. This is currently the same as the HttpServletResponse![]() from which it extends. |
| sling |
SlingScriptHelper![]() , containing convenience methods for scripts, mainly sling.include('/some/other/resource') for including the responses of other resources inside this response (eg. embedding header html snippets) and sling.getService(foo.bar.Service.class) to retrieve OSGi services available in Sling (Class notation depending on scripting language). |
| resource |
Current Resource![]() to handle, depending on the URL of the request. Same as request.getResource(). |
| reader |
Direct access to the Reader![]() of the request - same as request.getReader(). Use it for reading the data of an HTTP request body. |
| out |
Direct access to the PrintWriter![]() of the response - same as response.getWriter(). Use it for writing to the HTTP response body. |
| flush |
Indicates whether the output used by the script shall be flushed after the script evaluation ended. It is a Boolean, so use TRUE for flushing or FALSE for not flushing, which is the default value. The boolean value notation depends on the scripting language. |
| log |
Provides an SLF4J Logger![]() for logging to the Sling log system from within scripts, eg. log.info("Executing my script"). |
See also the api documentation of the org.apache.sling.api.scripting.SlingBindings.java![]()
which defines the common scripting variables.
