微信小程序请求封装

requers.js

  /**
   * Promise封装微信请求
   */
  function request(url, method, data, contentType = 'json', host) {
    contentType === 'form' && (contentType = 'application/x-www-form-urlencoded')
    contentType === 'json' && (contentType = 'application/json; charset=utf-8')
    contentType === 'file' && (contentType = 'multipart/form-data')
    let header = {
      'Content-Type': contentType,
      Authorization: wx.getStorageSync('token')
    }
    return new Promise((resolve, reject) => {
      wx.request({
        url: host + url,
        method: method,
        data: data,
        header: header,
        timeout: 6000,
        success: function (res) {
          if (res.statusCode === 401) {
          //  ...
          }
          resolve(res.data)
        },
        fail: function (err) {
          reject(err);
        }
      })
    })
  }
  module.exports = request

api.js

const app = getApp()
import request from './request'
const baseUrl = app.globalData.baseUrl

module.exports = {
  common: {
    login(params) {
      return request('/core/sys/XXXX', 'POST', params, 'form', baseUrl)
    },
    // ...
  },
  // ...
}

使用

    app.$api.common.login(data).then(res => {
      if (res.code === 200) {
        
      }
    })
