html - 错误的URI on Ruby on Rails:是因为很长吗？

所以我有一个网站，完全正常工作，一些uri编码在url中。
但是，当我尝试将url传递给chrome浏览器时：
http://somewhere:3000/find/someOne?utf8=%E2%9C%93&search=someThing&choicen=no&querys={%22peopleName%22%3A%22%22%2C%22peopleGroup%22%3A%22%22%2C%22place%22%3A%22%22%2C%22pip%22%3A%22%22%2C%22hw%22%3A%22%22%2C%22somerock%22%3A%22%22%2C%22rocksomerock%22%3A%22%22%2C%22diedAt%22%3A%222016-01-01%20-%202016-12-31%22%2C%22borndAt%22%3A%22%22%2C%22taxRate%22%3A%22%22}
--它在浏览器中向我抛出一个错误：

在Rails控制台中也显示[2016-07-04 18:11:31] ERROR bad URI。
版本：

知道怎么让它工作吗？是因为uri中的{和}还是因为它太长？

最佳答案

在收到请求时分析控制器中的路径，使用Rack::Utils#parse_nested_query，请参阅：http://www.rubydoc.info/github/rack/rack/master/Rack/Utils.parse_nested_query

# config/routes.rb

get '/find/someOne/*str' => 'find#someOne'


# app/controllers/find_controller.rb

class FindController < ApplicationController
  def someOne
    custom_params = Rack::Utils.parse_nested_query(request.env['ORIGINAL_FULLPATH'])
    querys_hash = JSON.parse(custom_params["querys"])
  end
end
