api工具类(utils/http.js)

const appId = 'wxbdb4d63f81d98228' //此处为appId
class HTTP {

export {
	HTTP
}

model层获取数据(models/app.js)

import { HTTP } from 'utils/http.js'

class AppModel extends HTTP {
  login(params) {
    return this.request({
      url: `${this.baseUrl}/api/login`,
      method: 'POST',
      data: {
        ...params
      }
    })
  }
}

export { AppModel }

调用

import { AppModel } from 'models/app.js'
const appModel = new AppModel()
appModel.login(params)
  .then(response => {
    uni.showLoading({
      title: '加载中'
    })
    setTimeout(() => {
      uni.hideLoading();
    })
  })
  .catch(errors => {
    uni.hideLoading();
  })
