使用Devise 1.3对JSON登录请求进行身份验证

I am new to rails. I am trying to write an API for a mobile application which authenticates using JSON. I want to use Devise for the authentication. I believe Devise >1.3 adds support for JSON as well but I cant find any examples or literature on it.

我是铁杆新手。我正在尝试为使用JSON进行身份验证的移动应用程序编写API。我想使用Devise进行身份验证。我相信Devise> 1.3也增加了对JSON的支持，但我找不到任何关于它的例子或文献。

Can someone please point me to any resource for this or provide some sample code?

有人可以指出我的任何资源或提供一些示例代码？

Thanks! Satyam

Perhaps this one > http://jessehowarth.com/devise?

也许这个> http://jessehowarth.com/devise？

I plan to do the same thing in a week or two.

I couldn't get to the linked page in the top answer so I thought I would add my own. You don't need to create any custom controllers. All you need to do is the following:

我无法进入顶部答案中的链接页面，所以我想我会添加自己的。您无需创建任何自定义控制器。您需要做的就是以下内容：

In your application.rb add the following in your application class

在application.rb中，在应用程序类中添加以下内容

config.to_prepare do
  DeviseController.respond_to :html, :json
end

In config/initializers/devise.rb add :json to the formats. This line is commented out by default so you will need to uncomment the line.

在config / initializers / devise.rb中添加：json格式。默认情况下，此行已注释掉，因此您需要取消注释该行。

config.navigational_formats = ['*/*', :html, :json]

After this, you can send a json object to sign_in.json or whatever you have set up in your routes for sign-in.

在此之后，您可以将json对象发送到sign_in.json或您在路由中设置的任何用于登录的内容。

{
  "user": {
    "email": "blah@blah.com",
    "password": "blah"
  }
}

And on success it will return 201 created, and the logged in user as a JSON object. On error it will return 401 with a JSON message indicating the reason for failure.

并且在成功时它将返回201创建，并将登录用户作为JSON对象。如果出错，它将返回401，并带有指示失败原因的JSON消息。

Example:

例：

{"error":"Invalid email or password."}

Here is a good example if you are using Backbone/Marionntte on the front end.

如果您在前端使用Backbone / Marionntte，这是一个很好的例子。

The Jesse Howarth's solution will break logging with browser when using html format responses. If you want to make both JSON and HTML to work try someting like this:

使用html格式响应时，Jesse Howarth的解决方案将破坏浏览器的日志记录。如果你想让JSON和HTML都工作，试试这样：

class SessionsController < Devise::SessionsController
  def create
    resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new")
    set_flash_message(:notice, :signed_in) if is_navigational_format?
    sign_in(resource_name, resource)
    respond_to do |format|  
      format.html { respond_with resource, :location => after_sign_in_path_for(resource) }  
      format.json {  
         return render :json => {  :success => true, 
           :user => resource
         } 
      }  
    end
  end
end

And don't forget to change your routes to use this controller

并且不要忘记更改路由以使用此控制器
