通过原生 iOS 应用使用 Devise 创建用户帐户

Question

我有一个使用Devise 进行身份验证的本机Rails 应用程序（使用token_authenticatable 模块）。使用现有帐户，一旦获得令牌，我就可以使用 JSON 在我的本机 iOS 应用程序中成功执行 API 调用。

我想添加通过 iOS 应用程序创建新帐户的功能，而无需使用浏览器。 Devise 是否只允许通过 HTML 创建帐户？

我看过这篇文章 Rails/Devise - Creating new users via json request

并通过 CURL 尝试了各种方法，包括：

$ curl -H "Content-Type: application/json" -d '{"email":"who@me.com","password":"mypass"}' -vX POST http://localhost:5000/users.json
...

为设计启用 json

config.navigational_formats = ["/", :json]

并添加新文件

class RegistrationsController < Devise::RegistrationsController

  def create

    @user = User.create(params[:user])
    if @user.save
      render :json => {:state => {:code => 0}, :data => @user }
    else
      render :json => {:state => {:code => 1, :messages => @user.errors.full_messages} }
    end

  end
end

在路线中：

  devise_for :users, :controllers => {:registrations => "registrations"}

更新

json 也应该是这样的：

{"user" : {"email":"who@me.com","password":"mypass"}}
