Shrine upload_endpoint on Sinatra 400 Bad Request

[Daniel]

Report

Following the Shrine docs, seems simple to use upload_endpoint with sinatra!

just place the on config.ru

map "/upload" do
  run ImageUploader.upload_endpoint(:cache)
end

but after that and test with

curl -i -X POST http://localhost:9393/upload

the log spits out

Upload Not Found[daniel@daniel-82mf boilerplate]$ curl -i -X POST http://localhost:9393/upload
HTTP/1.1 400 Bad Request
Content-Type: text/plain
Content-Length: 16

my config.ru

# frozen_string_literal: true

# $LOAD_PATH.unshift '.'
require './config/environment'
# require_relative "../uploaders/image_uploader"

if ActiveRecord::Base.connection.migration_context.needs_migration?
  raise 'Migrations are pending. Run `rake db:migrate` to resolve the issue.'
end



#map '/upload/store' do
  # run Shrine.upload_enpdoint(:cache)

 # run ImageUploader.upload_endpoint(:store) => '/upload/store'
#end

map "/upload" do
  run ImageUploader.upload_endpoint(:cache)
end
use Rack::MethodOverride
use SessionController
use LocationsController
run ApplicationController

my shrine.rb initializer

# frozen_string_literal: true

require 'shrine'
require 'shrine/storage/file_system'


Shrine.storages = {
  cache: Shrine::Storage::FileSystem.new('public', prefix: 'uploads/cache'), # temporary
  store: Shrine::Storage::FileSystem.new('public', prefix: 'uploads') # permanent
}
Shrine.plugin :upload_endpoint#, url: true
Shrine.plugin :activerecord
Shrine.plugin :cached_attachment_data
Shrine.plugin :restore_cached_data

Shrine.plugin :rack_file # for non-Rails apps
Shrine.plugin :determine_mime_type

So I've tried the routes

post "/upload" do

local_file = params[‘image’][:filename]
temp_file = params[‘image’][:tempfile]

@location = image_upload(local_file, temp_file)

if @location.save

      erb :"/locations/new"
else
  erb :"/locations/new"

end
end

or

    post "/upload2" do
  uploader = ImageUploader.new(:cache)
  file     = Shrine.rack_file(params["file"]) # only `params[:file]` in Rails

  uploaded_file = uploader.upload(file)

  json uploaded_file.data
end

i even tried to place the after the controllers on config.ru

map "/upload" do
run ImageUploader.upload_endpoint(:cache)
end

an that result in

Upload Not Found[daniel@daniel-82mf boilerplate]$ curl -i -X POST http://localhost:9393/upload
HTTP/1.1 500 Internal Server Error
Content-Type: text/html;charset=utf-8

So someone can help configure shrine with sinatra we appreciate

You need to pass an actual file to the POST request, concretely a file multipart POST parameter.

$ curl -i -X POST -F file=@/path/to/file http://localhost:9393/upload
