Image Upload in Vapor 3 using PostgreSQL

Question

I\'m following this guys Martin Lasek Tutorials and now i\'m at \"image upload\". It seems that no one has the answer to the question \"How do you upload images i Vapor 3\"

Answer 1

This uses automatic decoding of the multi-part form:

router.get("upload") {
    request -> Future in
    return try request.view().render("upload")
}

struct ExampleUpload: Content {
    let document: File
}

// this saves the file into a Question
router.post(ExampleUpload.self, at:"upload") {
    request, upload -> Future in
    let question = try Question()
    question.imageData = upload.document.data
    question.imageName = upload.document.filename
    return question.save(on:request).transform(to: HTTPResponseStatus.ok)
}

The upload.leaf file is:

Using the type File enables the local filename of the uploaded file to be accessed as well as the file data. If you add in the rest of the Question fields to the ExampleUpload structure, you can use the route to capture the whole form's fields.
