Rails 当 public 目录下存在 index.html 时路径请求问题
在 Rails 开发环境下 (rails server 启动) 此时，如果 public 目录下有 index.html。当访问路径如下时： http://localhost:3000/ http://localhost:3000/index http://localhost:3000/index.html 为什么会优先访问 public/index.html?
Anything in the public directory is rendered as a static asset, so no Ruby code in there.
Instead, you should remove the index.html file in that directory, and replace it with something else within your app. For example, you can do something like this:
# app/controllers/site_controller.rb
class SiteController < ApplicationController
def index
# ...
end
end
# config/routes.rb
root to: 'site#index'
# app/views/site/index.html.erb
<!-- Your HTML and Ruby here -->
This will give you the behavior you want.
