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
@MultipartConfigannotation. To configure in web.xml add<multipart-config />to your<servlet>element. If you prefer annotations instead, place@MultipartConfigto 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 usefileMultiParams("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:
}}* @note Once any handler with FileUploadSupport has accessed the request, the fileParams returned by FileUploadSupport will remain fixed for the lifetime of the request.
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.
