Rails *已完成406不可接受“在生产中......在分段中工作

Question

我在生产服务器中遇到错误“ 已完成406不可接受 ”，我在登台服务器中没有遇到此错误。

相同的代码在暂存时工作正常但在生产中不起作用。这两个环境都安装了相同的gem。 我使用的是rails 3.0.10。

在我的生产环境中，GET请求作为html处理，但在暂存时它被处理为js。我已经为js格式定义了respond_to块。 我不确定为什么它在两种环境中表现不同。

此外，我尝试在routes.rb中添加默认格式为js，但这也无效。

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

但这也行不通。

以下是生产和分期的日志。

生产：

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"}

分期：

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

这让我很生气。 感谢您的帮助。

Answer 1

最后我经过大量的调试后得到了解决方案..

我的请求接受标头期待HTML，而服务器返回Javascript响应，因此浏览器无法接受。

在我的情况下，一个Javascript文件缺少application.html.erb中的javascript_include_tag。缺少的Javascript是jquery_ujs.js。基本上这设置了ajax加载的接受标头。此标记中包含的Javascripts将被缓存并存储。 所以我添加了缺少的Javascript并删除了缓存的文件夹和YIPPEE，我的问题得到了解决。

我将举一个小例子，我从博客中学到了一些东西。 似乎对其他人理解406错误会有所帮助。

406错误可以理解如下：假设我已经要求你阅读一本书，但我只能阅读英文和法文书籍。 如果您只有德语书籍，您会给我一个空的回复，其中包含“406 - 不可接受”的状态。

406是服务器告诉你“我有你要求的，但你不会接受它们”。

这就是http请求中的Accept标头的用途。 例如，如果HTTP请求包含仅接受“img / jpg”MIME类型的指示，则如果请求的文件是Excel电子表格，则服务器将发送406状态。

诊断：

• 请求其中一个页面并分析http请求标头
• 注意响应的MIME类型，字符集，GZIP编码*

“406不可接受”是一个不寻常的状态代码 - 最常见的是200,404,500，301。当服务器出现问题时，你只看到406，通常是愚蠢但很难诊断的东西。

Answer 2

我有同样的问题。 我的问题是我正在发出HTML请求，但我的respond_to块只接受了js。

所以我需要改变这个：

respond_to do |format|
  format.js
end

对此：

respond_to do |format|
  format.html
  format.js
end

然后一切都恢复了。
