有没有办法覆盖sinatra默认的NotFound错误页面("Sinatra不知道这个小曲")？我希望sinatra只显示一个普通的字符串作为"找不到方法",当它找不到合适的路由时,但是当我从路由中引发404错误时,我希望它显示传入的错误消息.

像这样实现not_found块:

 not_found do
    'Method not found.' 
  end

工作,但它不是一个有效的选项,因为我希望能够从这样的路线抛出我自己的NotFound错误消息:

 get '/' do
    begin
      # some processing that can raise an exception if resource not found
    rescue => e
      error 404, e.message.to_json
    end
  end

但正如预期的那样,not_found块会覆盖我的错误消息.

我有一个Sinatra :: Base webservice,我想从命令行Ruby程序开始,所以我有这个:

# command line program file
require 'mymodule/server'

puts "Running on 0.0.0.0:4567, debugging to STDOUT..."

MyModule::Server.run! bind: '0.0.0.0', port: 4567, environment: :production

这按预期工作但它抛出:

$ myscript
Running on 0.0.0.0:4567, debugging to STDOUT...
