How to send simple json response in Rails?
提问by MID
I need to send json response depends on user entered data in input, but I'm failing to send simple json request.
我需要发送 json 响应取决于用户在输入中输入的数据，但我无法发送简单的 json 请求。
I followed this article - http://paydrotalks.com/posts/45-standard-json-response-for-rails-and-jquery.
我关注了这篇文章 - http://paydrotalks.com/posts/45-standard-json-response-for-rails-and-jquery。
Added MimeType:
添加了 MimeType：
Mime::Type.register_alias "application/json", :jsonr, %w( text/x-json )
and in my controller:
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
but the screen is empty and here is response code from fiddler2 when I composed GET response to this action:
但是屏幕是空的，这里是 fiddler2 的响应代码，当我对这个操作编写 GET 响应时：
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

Not sure about dealing with custom MIME, but as for rendering JSON, this should work:
不确定处理自定义 MIME，但至于呈现 JSON，这应该有效：
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
Also it might help if you state which version of Ruby and Rails you are using.
如果您说明您使用的是哪个版本的 Ruby 和 Rails，这也可能会有所帮助。
