如何在Rails中URL转义字符串？ [英] How do I URL-escape a string in Rails?

问题描述

如果我在Rails中使用RHTML视图，则很容易进行URL转义：

If I'm in an RHTML view in Rails, it is easy to URL-escape something:

<a href="/redirect?href=<%=u target %>">Foo</a>

我如何在字符串中这样做？我想做这样的事情：

How do I do this in a string? I'd like to do something like this:

<% redirect_href = "/redirect?#{url_escape target}&amp;foo=bar&amp;baz=some_other_stuff" -%>
<a href="<%= redirect_href =>">Foo</a>

这必须是微不足道的吗？

This must be trivial, right?

推荐答案

CGI.escape 将会执行：

<% redirect_href = "/redirect?#{CGI.escape target}&amp;foo=bar&amp;baz=some_other_stuff" -%>
<a href="<%= redirect_href =>">Foo</a>
