Raylarım uygulamasında http 200 kodu iyi görünüyor ancak bir hata varsa denetleyicimin hatayı JSON'a iletmesini istiyorum, böylece Android uygulamamda bununla başa çıkabilirim. API json'a Http hatası yanıtları döndürme
bir oylama benim raylar sunucusunda aşağıdaki olsun başarılı ise

o (kişi önce oy verildiği için) aşağıdaki alıyorum başarısız olursa
Sorun Tamamlandı 302 Bulunan yanıtı Android uygulamamıza geri gönderemiyorum. Sadece boş geri geçer.Kontrolör: Bir hata varsa
def upvote
@article.upvote_by current_user
if @article.vote_registered?
flash[:success] = "Successfully liked"
respond_to do |format|
format.html {redirect_to :back }
format.json { render json: { count: @article.get_upvotes.size } }
end
else
flash[:danger] = "You have already liked this"
respond_to do |format|
format.html {redirect_to :back }
format.json { render json: { status: :found }, status: 302 }
end
end
end
Android uygulaması oylama ve dize WebResponse uğraşan geri boş geliyor. 401 yetkisiz, 302 bulundu, vb, hala boş geri dönerse fark etmez:
Çok teşekkürler.
