1、rails_kindeditor 的初始化集成请参考：https://github.com/Macrow/rails_kindeditor 2、rails_kindeditor 默认上传路径是项目 public 目录下，而我们有单独的上传图片接口，所以就把项目中 rails_kindeditor.rb 中的 config.upload_dir 这行注释掉了（可忽略），把

$(function(){
    KindEditor.create('#item_new_news_contents', {"items":["source","|","undo","redo","|","justifyleft","justifycenter","justifyright","justifyfull","fontname","fontsize","|","forecolor","bold","italic","underline","|","image","multiimage","media","preview"],"width":"100%","height":300,"allowFileManager":true,"uploadJson":"/img/uploadimg?city=123&aa=345&style=test","fileManagerJson":"http://192.168.1.96:2998/kindeditor/filemanager",urlType:'domain'});
  })

里面的 uploadJson 修改成自己的图片上传接口，最重要的是返回值要是 Object 类型。

Object {error: 0, url: "http://xxx.com/images/263804351010818/news/285…914/info/31cd5ce8-4f6b-4bbd-96f8-a9ec3f7d9d8b.jpg"}
