Question

我正在使用Ruby on Rails应用程序，该应用程序对第三方服务进行客户端API调用。然后它从第三方API获取字符串并使用它们生成URI。

不幸的是，由于编码错误，Rails无法解析某些URI。我试过通过encodeURIComponent运行字符串，但这不能解决问题。

这是我得到的错误：

Processing ApplicationController#index (for 67.101.113.66 at 2010-08-12 23:24:55) [GET]
  Parameters: {"name"=>"Camilo Andr\xE9s \xD1ustes", "recipient_id"=>"279"}

  /usr/ruby1.9.1/bin/thin:19:in `load'

  /usr/ruby1.9.1/bin/thin:19:in `<main>'

如何正确处理这些字符串作为我的应用程序的输入？

Answer 1

这对我有用：<%= u name -%>

每次我必须在我的视图中传递身份验证令牌时使用此技术： <%= u form_authenticity_token %>

由于以上是针对视图的，如果你想要特定于ruby：

require 'uri'
foo = "http://google.com?query=hello"

bad = URI.escape(foo)
good = URI.escape(foo, Regexp.new("[^#{URI::PATTERN::UNRESERVED}]"))

bad_uri = "http://mysite.com?service=#{bad}&bar=blah"
good_uri = "http://mysite.com?service=#{good}&bar=blah"

puts bad_uri
# outputs "http://mysite.com?service=http://google.com?query=hello&bar=blah"

puts good_uri
# outputs "http://mysite.com?service=http%3A%2F%2Fgoogle.com%3Fquery%3Dhello&bar=blah"

希望这有帮助。
