恩codeuricomponent在轨对其进行解码 [英] Encodeuricomponent decoding it in rails

问题描述

通常情况下轨神奇地去codeS均 PARAMS 。现在，我得到一个JavaScript这确实 PARAMS =值=+ EN codeURIComponent（'AB＃CD'）; ，然后调用 HTTP ：//服务器/控制器值= AB％23cd ？。如果我访问 PARAMS [：值] 在我的控制器，它包含 AB％23cd ，而不是 AB＃CD 因为我期望的那样。

Normally rails magically decodes all params. Now I got a javascript which does params="value="+encodeURIComponent('ab#cd'); and then calls http://server/controller?value=ab%23cd. If I access params[:value] in my controller, it contains ab%23cd and not ab#cd as I would expect.

如何解决此问题？为什么导轨这个参数没有自动解码？

How to solve this? Why does rails no auto decoding of this param?

推荐答案

Rails的自动的处理参数与以下逻辑。

Rails "automagically" handles parameters with the following logic.

如果请求的是得到它会去查询字符串code什么：

If the request is GET it will decode anything in the query string:

GET http://server/controller?value=ab%23cd
  On the server this will generate params['value'] as ab#cd

如果该请求是一个查询字符串POST它将C中，它不会去$ C $：

If the request is a POST with a query string it will not decode it:

POST http://server/controller?value=ab%23cd
  On the server this will generate params['value'] as ab%23cd

如果该请求是数据参数的POST，它会去code的：

If the request is a POST with data parameters, it will decode it:

POST http://server/controller
  data: value=ab%23cd
  On the server this will generate params['value'] as ab#cd

我怀疑你所看到的，因为你包括与 POST 的要求，而不是一个查询字符串，这个问题 GET 要求等Rails是不是查询字符串解码。

I suspect that you're seeing this issue because you're including a query string with a POST request instead of a GET request and so Rails isn't decoding the query string.
