JSON响应时出现406错误 [英] 406 error when responding with json
问题描述
我正试图通过batman-rails gem与node.js框架batman.js一起运行Rails应用程序.
I'm trying to get a rails app running with the node.js framework batman.js via the batman-rails gem.
当我在Rails控制器中响应json时,每次都会收到406错误,我也不知道为什么.这是我的控制器:
When I'm responding with json in my rails controller, I get a 406 error everytime, and I don't know why. Here's my controller:
respond_to :json
def index
respond_with Sample.all
end
无论如何,这都会给我406.我认为这与蝙蝠侠无关,但与护栏本身有关.但是,出于良好的考虑,这是我的蝙蝠侠代码:
This gives me a 406 no matter what. I do not think this is related to batman, but rails itself. But for good measure, here's my batman code:
index: (params) ->
TopNavTemplate.Sample.load (err) -> throw err if err
@set 'samples', TopNavTemplate.Sample.get('all')
然后我的index.html.erb文件只是说'index',它实际上还没有对蝙蝠侠做任何事情.
And then my index.html.erb file simply says 'index', it isn't really doing anything with batman yet.
有很多406个与JSON相关的问题,我还不能真正将它们应用于我的情况.使Rails使用JSON响应时我做错了吗?
There is a lot of 406 JSON related questions, I haven't really been able to apply them yet to my situation. Is there something I'm doing wrong to make rails respond_with JSON?
推荐答案
好吧,我制作了一个非常简单的应用程序来检查您的情况:
Alright, I made a very simple app to check out your situation:
SamplesController.rb
SamplesController.rb
class SamplesController < ApplicationController
respond_to :json
def show
respond_with Sample.find(params[:id])
end
def index
respond_with Sample.all
end
end
当我访问/samples.json
和samples/1.json
时,它按预期工作.但是,当我去/samples
和/samples/1
(没有.json扩展名)时,出现了406错误.
When I visited /samples.json
and samples/1.json
, it worked as intended. However, when I went to /samples
and /samples/1
(no .json extension), I got a 406 error.
为了使URL在不带.json扩展名的情况下工作,您需要按以下步骤修改config/routes.rb
文件:
In order to have the URL's work without the .json extension, you need to modify your config/routes.rb
file as follows:
resources :samples, defaults: {format: :json}
否则,Rails应用程序将尝试使用HTML响应来响应请求.
Otherwise, the Rails application will attempt to respond to the request with an HTML response.
