Question

I want to design a controller in Grails which accepts multipart like “XML+binary file1+binary file2+…”. How could I parse this request? I appreciate any sample codes!

Thanks,

So I’m assuming you are talking about an input type file that has the multiple attribute. Here is how you would process it server side:

List<MultipartFile> files = request.multiFileMap.nameOfInputFileElement

files.each { uploadedFile ->

    if(!uploadedFile.empty){

        File newFile = new File( parentDir, uploadedFile.originalFilename)
        uploadedFile.transferTo(newFile)
    }
}
