Try it

             // init中添加如下代码
          init:{  
            'Key': function(up, file) {
                // 若想在前端对每个文件的key进行个性化处理，可以配置该函数
                // 该配置必须要在 unique_names: false , save_key: false 时才生效

                // do something with key here
                return key;
            }
          }
