How to use the d2-crud-plus.d2CrudPlus.util function in d2-crud-plus

qiniu: {
    bucket: 'd2p-demo',
    getToken (custom) {
      return request({
        url: '/upload/qiniu/getToken',
        method: 'get'
      }).then(ret => {
        return ret.data // {token:xxx,expires:xxx}
      })
    },
    domain: 'http://d2p.file.veryreader.com'
  }
})

//  自定义字段类型示例
d2CrudPlus.util.columnResolve.addTypes({
  'time2': {
    form: { component: { name: 'el-date-picker', props: { type: 'datetime' } } }, // 编辑时支持日期时间
    search: { component: { props: { type: 'date' } } }, // 搜索时只支持日期
    formatter (row, column, value, index) {
      return value + '-->我是自定义字段类型：time2'
    },
    _handle (column) {
      //  此方法主要将column中某些依赖的用户配置的属性放到默认配置中，比如数据字典的配置
      if (column.dict != null) {
        this.form.component.props.dict = column.dict
        this.component.props.dict = column.dict
      }
    }
  }
})
