MultipartForm

To access multipart form entries, you can parse the binary with MultipartForm(). This returns a map[string][]string, so given a key, the value will be a string slice.

  1. func (c *Ctx) MultipartForm() (*multipart.Form, error)
  1. app.Post("/", func(c *fiber.Ctx) error {
  2.   // Parse the multipart form:
  3.   if form, err := c.MultipartForm(); err == nil {
  4.     // => *multipart.Form
  6.     if token := form.Value["token"]; len(token) > 0 {
  7.       // Get key value:
  8.       fmt.Println(token[0])
  9.     }
  11.     // Get all files from "documents" key:
  12.     files := form.File["documents"]
  13.     // => []*multipart.FileHeader
  15.     // Loop through files:
  16.     for _, file := range files {
  17.       fmt.Println(file.Filename, file.Size, file.Header["Content-Type"][0])
  18.       // => "tutorial.pdf" 360641 "application/pdf"
  20.       // Save the files to disk:
  21.       if err := c.SaveFile(file, fmt.Sprintf("./%s", file.Filename)); err != nil {
  22.         return err
  23.       }
  24.     }
  25.   }
  27.   return err
  28. })
