axios 请求

普通，显示“正在加载”

  request() {
    let data = {
      id: "1000001"
    };
    console.log(data);
    this.$vux.loading.show({ text: "正在加载" });
    this.$api.indexInterface.requestData(data)
      .then(res => {
        this.$vux.loading.hide();
        res = res.data;
        if (res.success) {
          this.list = res.data;
        } else {
          this.$vux.toast.show({ type: "cancel", text: "加载失败" });  //res.retMsg
        }
      })
      .catch(err => {
        this.$vux.loading.hide();
        console.error(err);
      });
  },

this.$api.indexInterface.requestData({
  id: "1000001"
}).then(res => {
  res = res.data;
  if (res.success) {
    this.table.count = res.data.count;
    this.table.body = (() => {
      let arr = [];
      [...res.data.dbPageList].map(m => arr.push(m));
      return arr;
    })();
  } else {
    this.$vux.toast.show({ type: "cancel", text: "加载失败" });  //res.retMsg
  }
}).catch(err => console.error(err))

Promise封装

const promise = new Promise((resolve, reject) => {
  this.$api.indexInterface.requestData({
      id: "1000001"
  }).then(res => {
    res = res.data;
    res.success ? resolve(res.data) : reject(res.retMsg);
  }).catch(err => console.error(err))
});

promise.then(resolve => {
  [...resolve].map(m => this.table.body.push(m));
}, reject => {
  console.error(reject);
})
