我在生产服务器中遇到了错误“ Completed 406 Not Acceptable”，在登台服务器中没有遇到该错误。
相同的代码可以在暂存阶段正常工作，但不能在生产环境中运行。两个环境都安装了相同的gem。我使用的是Rails 3.0.10版本。
在我的生产环境中，GET请求被处理为html，但在过渡过程中被处理为js。我已定义了js格式的response_to块。我不确定为什么它在两种环境中的行为会有所不同。
我也尝试在route.rb中将默认格式添加为js，但这也无法正常工作。
match 'releases/cycle_paginate', :to => 'releases#cycle_paginate', :defaults => { :format => 'js' }
但这也不起作用。
以下是生产和暂存日志。
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
这让我发疯。感谢你的帮助。

最佳答案
经过大量的调试，终于得到了解决方案..
我的请求接受标头在服务器返回Javascript响应时期望HTML，因此浏览器不接受。
在我的情况下，一个Javascript文件在application.html.erb中缺少javascript_include_tag。该Javascript缺少是jquery_ujs.js。基本上，这将设置ajax加载的accept标头。此标签中包含的Javascript将被缓存和存储。
所以我添加了缺少的Javascript并删除了缓存的文件夹和YIPPEE，我的问题得到解决。
我将举一个我从博客中学到的小例子。看来这对其他人理解406错误会有所帮助。
406错误可以理解如下：
假设我要你读书，但我只能读英语和法语的书。如果您只有德文书籍，您会给我一个空的答复，状态为“ 406-不可接受”。
服务器406告诉您“我有您要的内容，但您不接受”。
这就是http请求中的Accept标头所针对的。例如，如果HTTP请求包含仅接受“ img / jpg” MIME类型的说明，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：
请求这些页面之一并分析http请求标头
注意响应的MIME类型，字符集，GZIP编码*
“ 406 not accept”是不寻常的状态码-最常见的是200、404、500、301。只有在服务器出现问题时（通常是愚蠢但难以诊断），您才会看到406。
