渲染JSON但在Rails 3.0.1中编码字符 [英] Rendering json but encoded characters in rails 3.0.1

问题描述

我正在使用rails3.0.10

i'm using rails3.0.10

def districts
    @names = Node.where("name like ?", "%#{params[:term]}%").limit(5).map(&:name)
    respond_to do |format|
      format.json {render :json => @names}
      format.xml {render :xml => @names}
    end
  end

渲染xml获取正确的名称
但是渲染json使名称的编码方式类似于=> ["name1"，"name2"，"\ ufffd \ ufffd \ ufffd \ ufffd \ ufffd \ ufffd \ ufffd \ ufffd"]
我想用正确的语言来命名正确的名字

render xml get right names
but render json make the names is encoded like => ["name1", "name2", "\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd"]
i want to get right names in their right language

有什么帮助吗?

预先感谢

推荐答案

在发送响应之前，您必须将字符串强制为UTF-8

before sending the response you must force the strings to be UTF-8

为此行添加上面的代码

@names.map{|name| name.force_encoding('UTF-8')}

这将循环名称数组，并强制将它们从ASCII-8BIT编码为UTF-8

this will loop the array of names and force them to be encoded from ASCII-8BIT to UTF-8

所以我的方法将是

def districts
  @names = Node.where("name like ?", "%#{params[:term]}%").limit(5).map(&:name)
  @names.map{|name| name.force_encoding('UTF-8')}
  respond_to do |format|
    format.json {render :json => @names}
    format.xml {render :xml => @names}
  end
end

您还可以像

class Node < ActiveRecord::Base
 def name
  super().force_encoding('UTF-8')
 end
end

我确定此代码可正常运行
