§Handling file upload
§Uploading files in a form using multipart/form-data
The standard way to upload files in a web application is to use a form with a special multipart/form-data
encoding, which allows to mix standard form data with file attachments.
Start by writing an HTML form:
@form(action = routes.Application.upload, 'enctype -> "multipart/form-data") {
<input type="file" name="picture">
<p>
<input type="submit">
</p>
}
Now let’s define the upload
action:
public static Result upload() {
MultipartFormData body = request().body().asMultipartFormData();
FilePart picture = body.getFile("picture");
if (picture != null) {
String fileName = picture.getFilename();
String contentType = picture.getContentType();
File file = picture.getFile();
return ok("File uploaded");
} else {
flash("error", "Missing file");
return redirect(routes.Application.index());
}
}
§Direct file upload
Another way to send files to the server is to use Ajax to upload files asynchronously from a form. In this case, the request body will not be encoded as multipart/form-data
, but will just contain the plain file contents.
public static Result upload() {
File file = request().body().asRaw().asFile();
return ok("File uploaded");
}
