html - 错误的 URI Ruby on Rails : is it because long?

Question

所以我有一个完全可用的网站，在 URL 中编码了一些 URI。

但是，当我尝试将 URL 传递到我的 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}

-- 它在浏览器中抛出一个错误:

Bad Request

WEBrick/1.3.1 (Ruby/1.9.3/2014-11-13) at somewhere.com:3000

还在 Rails 控制台中显示 [2016-07-04 18:11:31] ERROR bad URI

版本:

• rails3
• ruby 1.9.3

知道如何让它工作吗？是因为URI中的{和}还是太长了？

根据传入请求解析 Controller 中的路径，使用 Rack::Utils#parse_nested_query，参见: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

通过控制台的例子:

$ bundle exec rails c
Running via Spring preloader in process 31944
Loading development environment (Rails 5.0.0)
irb(main):001:0> custom_params = Rack::Utils.parse_nested_query "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}"
