WARN 无法确定响应正文的内容长度.设置响应的内容长度或设置 Response#chunked = true

问题描述

可能的重复:
什么是"WARN 无法确定响应正文的内容长度."意思是我如何摆脱它?

我刚刚升级到 rails 3.2.2，现在在 rails s，页面加载时，我在日志中收到所有这些错误:

I just upgraded to rails 3.2.2, and now on rails s, page load, I get all these errors in the log:

[2012-03-07 19:46:14] WARN  Could not determine content-length of response body. Set content-length of the response or set Response#chunked = true
[2012-03-07 19:46:14] WARN  Could not determine content-length of response body. Set content-length of the response or set Response#chunked = true

根据之前的 SO 线程，我尝试了以下操作:

Per previous SO threads, I tried the following:

/config/application.rb

config.assets.logger = false
config.assets.logger = nil

这些都没有用.关于如何为此错误禁用此日志记录的任何想法?或者解决这个问题:)

None of these worked. Any ideas on how to disable this logging for this error? Or to fix the issue :)

谢谢

推荐答案

这是 Webrick 的问题.您可以改用瘦".

This is a problem of Webrick.you can use "Thin" instead.

将此添加到 Gemfile

Add this to Gemfile

gem 'thin'

然后 rails s 将使用 Thin 而不是 Webrick，并且警告将消失.

then rails s will use thin instead of Webrick, and the warn will disappear.
