访问控制器中的create方法时出现WEBrick :: HTTPStatus :: LengthRequired错误

Question

我有一个非常简单的控制器设置:

class LibrariesController < ApplicationController

...

  def create
    @user.libraries << Library.new(params)
    @user.save
    render :json => "success!"
  end

...

end

基本上,每当我尝试使用HTTParty.post访问LibrariesController的create方法时,我在服务器上得到一个WEBrick :: HTTPStatus :: LengthRequired错误.甚至没有访问该方法!这是堆栈跟踪(这是完整的输出服务器端 - 注意控制器甚至没有被访问):

我正在运行rails 2.3.5和ruby 1.8.7.任何帮助将不胜感激.如果您需要更多详细信息,请告诉我们.

Answer 1

当我做一个空身的POST时,我得到了这个.我正在使用卷曲.

就像是:

curl -X POST http://url/

我添加了-d'',它解决了这个问题.

curl -X POST http://url/ -d ''

在您的情况下,您可能需要在HTTParty.post中的一个:body =>''属性中添加一些内容

Answer 2

使用:body而不是:query发布和发出请求.

Answer 3

我不知道这是否仍然与 Webrick 相关，或者是否已修复，但您收到的错误有一个已知问题Read line 2 on this TODO page on RubyForge

您是否尝试过gem install mongrel使用 mongrel 或其他 ruby​​ 服务器运行它？
