Cannot parse multipart form without form: attributes

[emersion]

This works:

type UploadForm struct {
    Title      string                `form:"Title"`
    TextUpload *multipart.FileHeader `form:"TextUpload"`
}

But this produces an empty struct:

type UploadForm struct {
    Title      string
    TextUpload *multipart.FileHeader
}

But this produces an empty struct:

Why should this work?

[emersion]

Because it works with JSON:

type UploadForm struct {
    Title      string
    TextUpload *multipart.FileHeader
}

// is exactly the same as:

type UploadForm struct {
    Title      string `json:"Title"`
    TextUpload *multipart.FileHeader `json:"TextUpload"`
}
