Type Members

1. trait AsyncCSRFTokenSupport extends AnyRef

   

   Provides cross-site request forgery protection.

   Provides cross-site request forgery protection.

   If a request is determined to be forged, the handleForgery() hook is invoked. Otherwise, a token for the next request is prepared with prepareCsrfToken.

2. trait CORSSupport extends AnyRef

   

   CORS(Cross-Origin Resource Sharing) Support.

3. trait CSRFTokenSupport extends AnyRef

   

   Provides cross-site request forgery protection.

   Provides cross-site request forgery protection.

   If a request is determined to be forged, the handleForgery() hook is invoked. Otherwise, a token for the next request is prepared with prepareCsrfToken.

4. trait ChunkedResponseSupport extends AnyRef

   

   Chunked Response (Transfer-Encoding: chunked).

5. trait ContentEncodingSupport extends Handler

   

   SkinnyMicro handler for gzipped responses.

6. trait FileUploadSupport extends SkinnyMicroBase with HasMultipartConfig

   

   FileUploadSupport can be mixed into a skinny.micro.SkinnyMicroServlet to provide easy access to data submitted as part of a multipart HTTP request.

   FileUploadSupport can be mixed into a skinny.micro.SkinnyMicroServlet to provide easy access to data submitted as part of a multipart HTTP request.

   Commonly this is used for retrieving uploaded files.

   Once the trait has been mixed into your handler, you need to enable multipart configuration in your web.xml or by using @MultipartConfig annotation. To configure in web.xml add <multipart-config /> to your <servlet> element. If you prefer annotations instead, place @MultipartConfig to your handler. Both ways provide some further configuration options, such as specifying the max total request size and max size for invidual files in the request. You might want to set these to prevent users from uploading too large files.

   When the configuration has been done, you can access any files using fileParams("myFile") where myFile is the name of the parameter used to upload the file being retrieved. If you are expecting multiple files with the same name, you can use fileMultiParams("files[]") to access them all.

   To handle any errors that are caused by multipart handling, you need to configure an error handler to your handler class:

   import skinny.micro.servlet.SizeLimitExceededException
   import skinny.micro.servlet.FileUploadSupport
   
   @MultipartConfig(maxFileSize=1024*1024)
   class FileEaterServlet extends SkinnyMicroServlet with FileUploadSupport {
     error {
       case e: SizeConstrainttExceededException => "Oh, too much! Can't take it all."
       case e: IOException                      => "Server denied me my meal, thanks anyway."
     }
   
     post("/eatfile") {
       "Thanks! You just provided me " + fileParams("lunch").size + " bytes for a lunch."
     }
   }

   }}* @note Once any handler with FileUploadSupport has accessed the request, the fileParams returned by FileUploadSupport will remain fixed for the lifetime of the request.

   Note

   Will not work on Jetty versions prior to 8.1.3. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=376324. The old scalatra-fileupload module still works for earlier versions of Jetty.

7. trait FlashMapSupport extends Handler with ServletContextAccessor with SkinnyContextInitializer with UnstableAccessValidationConfig with ServletApiImplicits with SessionImplicits

   

   Allows an action to set key-value pairs in a transient state that is accessible only to the next action and is expired immediately after that.

   Allows an action to set key-value pairs in a transient state that is accessible only to the next action and is expired immediately after that. This is especially useful when using the POST-REDIRECT-GET pattern to trace the result of an operation.

   post("/article/create") {
     // create session
     flash("notice") = "article created succesfully"
     redirect("/home")
   }
   get("/home") {
     // this will access the value set in previous action
     stuff_with(flash("notice"))
   }
