越來越不想寫部落格了，真的是累！

好了，廢話不多說，進入正題。

前臺：

既然你們都走到這裡來了，那麼前面的就不在多說了，直接進去配置好的頁面。

<script type="text/javascript">
  var ue = UE.getEditor('editor', {
    maximumWords : 2000000, //允許的最大字元數
    sourceEditorFirst : false,
    allHtmlEnabled : true,
  });

  //圖片和檔案存入OSS中
  UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
  UE.Editor.prototype.getActionUrl = function(action) {
    if (action == 'uploadimage' || action == 'uploadfile') {
      return '${path}/web/ueuploadimageoss!ueUploadImgaeOSS';  //此處改需要把圖片上傳到哪個Action（Controller）中
    } else {
      return this._bkGetActionUrl.call(this, action);
    }
  };
</script>
 

需要上傳的路徑返回過去，記得把config.json 中的 imageUrlPrefix 清空。

非常簡單，核心是：只要知道哪裡改上傳的URL 和怎麼返回資料格式。
