MultiJson::LoadError token tak terduga

Saya mencoba mengikuti tutorial ini untuk membuat otentikasi token menggunakan Rancangan:

http://www.strukturedkaos.com/2011/09/19/soup-to-nuts-token-authentication-for-android-using-rails-3-devise/

Namun, ketika saya mencoba memastikan bahwa session_controller yang diuraikan dalam tutorial berfungsi dengan benar, saya mendapatkan kesalahan:

Ini adalah perintah yang saya uji dengan:

curl -v -H 'Content-Type: application/json' -H 'Accept: application/json' -X POST http://localhost:3000/sessions -d "{'user':{'username':'test', 'password':'password'}}"

Apa yang saya lakukan salah?

String JSON tidak dapat dibatasi dengan tanda kutip tunggal. Anda harus menggunakan tanda kutip ganda di sekitar kunci dan nilai Anda, dan tanda kutip tunggal untuk keluar dari data POST dari shell.

curl -v -H 'Content-Type: application/json' -H 'Accept: application/json' -X POST http://localhost:3000/sessions -d '{"user":{"username":"test", "password":"password"}}'

Kesalahan ini biasanya terjadi ketika JSON tidak ditulis dengan benar. Saya sarankan memeriksa format JSON menggunakan alat seperti: http://www.jsoneditoronline.org/
