 * # 一、组件引用
 * 模块引用：如app.json根组件引用
 * ``` json
 * "usingComponents": {
 *  "upload": "/components/upload/index",
 * }
 * ```
 * 上传令牌获取：xxxpage.js
 * ``` js
 *  async getUptoken() {
 *      // 根据config.js全局配置company的ID来获取上传口令
        let res = await Parse.Cloud.run('qiniu_uptoken', {
            company: getApp().globalData.company
        })
        console.log(Object.keys(res));
        console.log(res);
        this.setData({
            uptokenURL: res.uptoken,
            domain: res.domain,
            uploadURL: res.zoneUrl
        })
    },
    async onLoad(){
      this.getUptoken()
    }
 * ```
 # 二、组件示例
 * 模板标签：xxxpage.wxml 页面中使用<upload>标签传参使用
