Rails的*完成406不可接受＆QUOT;在生产上分期..working [英] Rails *Completed 406 Not Acceptable" in production ..working in Staging

问题描述

我坚持到错误的，我没有面临临时服务器生产服务器已完成406不可接受。

I am stuck with an error "Completed 406 Not Acceptable" in the production server which I am not facing in the staging server .

同code工作正常分期，但安装了相同的宝石生产。无论环境下不能正常工作。我使用的是轨道版本3.0.10。

Same code is working fine in staging but not working in production .Both environment has same gems installed . I am using a rails version 3.0.10.

在我的生产环境中，GET请求被处理为HTML，但在分期为爵士。我已经定义了的respond_to块只为JS格式对其进行处理。我不知道为什么它是不同的行为在两种环境。

In my production environment , the GET request is processed as a html but in staging it is processed as js .I have defined the respond_to block only for js format . I am not sure why it is behaving differently in two environments.

此外，我曾尝试加入默认格式，在routes.rb中JS但也不能正常工作。

Also I have tried adding the defaults format as js in the routes.rb but that also is not working.

match 'releases/cycle_paginate', :to => 'releases#cycle_paginate', :defaults => { :format => 'js' }

不过，这也不能正常工作。

But this is also not working .

下面是日志，生产和分期。

Below is the log for production and staging .

制作：

Started GET "/releases/cycle_paginate/2?id=4" for 10.30.10.67 at Wed Aug 14 07:13:45 -0400 2013
  Processing by ReleasesController#cycle_paginate as JS
  Parameters: {"id"=>"4", "page"=>"2"}

切入：

Started GET "/releases/cycle_paginate/2?id=53" for 10.30.10.67 at Wed Aug 14 06:42:45 -0400 2013
  Processing by ReleasesController#cycle_paginate as HTML
  Parameters: {"id"=>"53", "page"=>"2"}

控制器：

def cycle_paginate

  @release = Release.find(params[:id])

  @cycles = []
  @cycles = Kaminari.paginate_array(@release.cycles) \
                  .page(params[:page]) \
                  .per(5)
  last_page = @cycles.num_pages
  if params[:page].to_i > last_page
    @cycles = @cycles.page(last_page)
  else
    @cycles = @cycles.page(params[:page].presence || 1)
  end
  respond_to do |format|
    format.js
  end
end

这是快把我逼疯了。鸭preciate你的帮助。

This is making me mad. Appreciate your help.

推荐答案

最后，我得到了很多的调试后的溶液。

Finally I got the solution after a lot of debugging ..

我的请求，接受头部期待一个HTML，而服务器返回一个js响应，以便不被浏览器接受。

My request accept header was expecting a HTML while server was returning a js response so that was not acceptable by browser .

在我的情况下，一个js文件中缺少application.html.erb .The的javascript_include_tag JavaScript的缺失是 * jquery_ujs.js * 。基本上这台接受头为Ajax加载.The javascipts包括在该标签将被缓存并存储。 所以我加了失踪JavaScript和删除缓存文件夹，并YIEPPE我的问题得到了解决。

In my case a js file was missing the javascript_include_tag in the application.html.erb .The javascript missing was *jquery_ujs.js* .Basically this sets the accept header for ajax loading .The javascipts included in this tag will be cached and stored. So I added the missing javascript and removed the cached folder and YIEPPE my problem got resolved.

会给出一个小例子，我学到什么地方从博客.Seems这将有利于别人理解406错误。

Will give a small example that I learnt somewhere from a blog .Seems it will be helpful for others to understand the 406 error.

可406错误理解为如下：  假如我问你一本书来读，但我只可以阅读英文和法文书籍。如果你只有在德国的书，你会给我一个的的一个空的响应。406 - 不接受状态的

406 error can be understood as below: Suppose I've asked you for a book to read, but I can only read books in English and French. If you only have books in German, you would give me an empty response with a "406 - not acceptable" status.

406是服务器告诉你我中有你问什么，但你不会接受他们。的

406 is the server telling you "I have what you asked for, but you won't accept them".

这就是Accept标头在HTTP请求是。举例来说，如果HTTP请求中包含的方向，它将只接受IMG / JPGMIME类型，服务器会发送一个406状态，如果请求的文件是一个Excel US preadsheet。

That's what Accept headers in the http request are for. For instance, if the http request includes directions that it will only accept "img/jpg" mime type, the server would send a 406 status if the file requested is an Excel spreadsheet.

要诊断：

• 在要求这些网页时，分析HTTP请求头
• 需要注意的是MIME类型的答复，字符集，GZIP编码*

406不能接受的，是一个不寻常的地位code - 最常见的有200，404，500，301。你只看到406时，什么是错的服务器，通常是一些愚蠢的，但很难诊断

"406 not acceptable" is an unusual status code - the most common are 200, 404, 500, 301. You only see a 406 when something is wrong with the server, usually something silly but hard to diagnose
