去datastore类里，看有没有定义put方法

  //变量缓存器
  export class DataStore {
      static getInstance() {
          if (DataStore.instance) {
              DataStore.instance = new DataStore();
          }
          return DataStore.instance;
      }
  
      constructor() {
              this.map = new Map();
          }
          //变量添加
      put(key, value) {
              this.map.set(key, value);
              return this;
          }
          //变量查询
      get(key) {
              return this.map.get(key);
          }
          //变量删除
      destroy() {
          for (let value of this.map.values()) {
              value = null;
          }
      }
  }
