Golang GET多部分表单数据

Let say I have a html form

<form enctype="multipart/form-data" action="http://localhost:8080/incarcat" method="post">
    <input type="file" name="file" multiple="multiple"/>
    <input type="checkbox" name="delete" value="delete">
    <input type="submit" value="Load" />
</form>

and the following go code

read_form, err := req.MultipartReader()
for {
    part, err_part := read_form.NextPart()
    if err_part == io.EOF {
        break
    }
    if part.FormName() == "file" {
        //do something with files
    } else if part.FormName() == "delete" {
        //curata_folder()
        log.Println("delete is: ", part.Header.Get("delete"))
    }
}

How do i get the value of "delete"?

part.Header.Get("delete"))

it's not working

    You can probably content yourself by using the request.ParseMultipartForm method, then use the request.FormValue to get values as usual. Note that you also have the request.MultipartForm to get access to your files.

    Example:

    func(w http.ResponseWriter, r *http.Request) {
        // Here the parameter is the size of the form data that should
        // be loaded in memory, the remaining being put in temporary
        // files
        r.ParseMultipartForm(0)
    
        fmt.Println(r.FormValue("delete"))
    }
