如何在Rails中发送简单的json响应?

问题描述

我需要发送json响应取决于输入中用户输入的数据，但是我无法发送简单的json请求.

I need to send json response depends on user entered data in input, but I'm failing to send simple json request.

我关注了这篇文章- http://paydrotalks.com/posts/45标准的json-response-for-rails-and-jquery .

添加了MimeType:

Added MimeType:

Mime::Type.register_alias "application/json", :jsonr, %w( text/x-json )

并在我的控制器中:

 def checkname
  respond_to do |format|
    format.jsonr do
      render :json => {
         :status => :ok,
         :message => "Success!",
         :html => "<b>congrats</b>"
      }.to_json
     end
  end
end

但是屏幕是空的，这是我对这个动作进行GET响应时来自fiddler2的响应代码:

but the screen is empty and here is response code from fiddler2 when I composed GET response to this action:

    HTTP/1.1 406 Not Acceptable
   Content-Type: text/html; charset=utf-8
   X-UA-Compatible: IE=Edge
   Cache-Control: no-cache
   X-Request-Id: 14a8467908d9ce322d054607efdacf92
   X-Runtime: 0.011000
   Content-Length: 1
   Connection: keep-alive
  Server: thin 1.4.1 codename Chromeo

我做错了什么?

推荐答案

不确定如何处理自定义MIME，但对于呈现JSON，这应该可以:

Not sure about dealing with custom MIME, but as for rendering JSON, this should work:

def testme
  respond_to do |format|
    msg = { :status => "ok", :message => "Success!", :html => "<b>...</b>" }
    format.json  { render :json => msg } # don't do msg.to_json
  end
end

如果您声明使用的是Ruby和Rails版本，这也可能会有所帮助.

Also it might help if you state which version of Ruby and Rails you are using.
